The reason is that the while loop runs infinitely until the break statement is executed. The break statement terminates the loop if the value of x is divisible by 5. However, the value of x is incremented at each iteration of the loop before checking the condition. Here is the step-by-step explanation of how this code works:

Step 1: Assign 1 to x.x = 1

Step 2: Start an infinite loop using the while True statement.

Step 3: Check if the value of x is divisible by 5 using the if x % 5 == 0 statement.

Step 4: If the value of x is divisible by 5, terminate the loop using the break statement.

Step 5: Print the value of x to the console using the print(x) statement.

Step 6: Increment the value of x by 1 using the x += 1 statement.

Step 7: Repeat steps 3-6 until the break statement is executed.

True. The function f(x)=2 ^x has a Taylor series at every point. The Taylor series expansion of a function represents the function as an infinite sum of terms involving the function's derivatives evaluated at a specific point.

The Taylor series provides an approximation of the function around that point.

For the function f(x)=2 ^x, the Taylor series expansion is given by:

f(x)=f(a)+f ′(a)(x−a)+ 2!f ′′(a) (x−a) 2+ 3!f ′′′(a)(x−a) 3 +…

Since the function f(x)=2 ^x  is differentiable for all real values of x, we can calculate its derivatives at any point a and use them to construct the Taylor series expansion. Therefore, the function  f(x)=2 ^x has a Taylor series at every point.

The critical points of the function f(x) = (x² - 9)^(1/3) are x = 0 and x = ±3. These points correspond to the values of x where the derivative of the function is equal to zero or does not exist.

To determine the critical points of the function f(x) = (x² - 9)^(1/3), we need to find the values of x where the derivative of the function is equal to zero or does not exist.

Let's start by finding the derivative of f(x) with respect to x. Using the chain rule, we have:

f'(x) = (1/3) * (x² - 9)^(-2/3) * 2x.

To find the critical points, we set f'(x) equal to zero and solve for x:

(1/3) * (x² - 9)^(-2/3) * 2x = 0.

Since the term (x² - 9)^(-2/3) cannot be zero (as it involves a negative exponent), the critical points occur when 2x = 0.

Solving 2x = 0, we find that x = 0 is a critical point.

Now, let's consider the values of x where the derivative does not exist. This happens when the term (x² - 9)^(-2/3) is zero, which occurs when x² - 9 = 0.

Solving x² - 9 = 0, we find x = ±3.

Therefore, the critical points of the function f(x) = (x² - 9)^(1/3) are:

A) x = 0

B) x = ±3

The measure of angle d is 160°.

The measure of angle d, which is coterminal with a -920° angle, can be determined by finding an angle within the range of 0° to 360° that is equivalent to the given angle.

To find the coterminal angle, we can add or subtract a multiple of 360° to the given angle.

In this case, we have a -920° angle, so we can add 360° repeatedly until we find an angle within the range of 0° to 360°. -920° + 360° = -560° -560° + 360° = -200° -200° + 360° = 160°

Therefore, the angle d is 160°.

This angle is coterminal with the -920° angle, meaning they both terminate in the same position on the coordinate plane.

It is important to note that angles can have multiple coterminal angles, as we can add or subtract 360° infinitely to find more coterminal angles.

In conclusion, the measure of angle d is 160°.

The value of fx + fy at [π/12, π/6] is (-3√6 + √2)/4.

To find the value of fx + fy at [π/12, π/6], we need to calculate the partial derivatives of f(x, y) with respect to x (fx) and y (fy), and then evaluate them at the given point.

First, let's find the partial derivative fx:

To find fx, we differentiate f(x, y) with respect to x while treating y as a constant. Using the chain rule, we get:

fx = -3sin(3x)sin(4y)

Next, let's find the partial derivative fy:

To find fy, we differentiate f(x, y) with respect to y while treating x as a constant. Using the chain rule, we get:

fy = 4cos(3x)cos(4y)

Now, let's evaluate fx + fy at [π/12, π/6]:

Substituting x = π/12 and y = π/6 into fx and fy, we have:

fx(π/12, π/6) = -3sin(3(π/12))sin(4(π/6))

fy(π/12, π/6) = 4cos(3(π/12))cos(4(π/6))

Simplifying the trigonometric functions, we get:

fx(π/12, π/6) = -3sin(π/4)sin(2π/3) = -3(√2/2)(√3/2) = -3√6/4

fy(π/12, π/6) = 4cos(π/4)cos(π/3) = 4(√2/2)(1/2) = √2/4

Finally, we can calculate the sum:

fx + fy = (-3√6/4) + (√2/4) = (-3√6 + √2)/4

Therefore, the value of fx + fy at [π/12, π/6] is (-3√6 + √2)/4.

The profit function is P = 63,000x - x² - 0.5x - 7300.

The profit function is increasing on the interval (0, 10,000) and decreasing on the interval (10,000, 50,000).

To obtain maximum profit, the restaurant needs to sell 10,000 hamburgers.

The profit function for the fast-food restaurant is determined by subtracting the cost function from the revenue function. In this case, the cost function is given as C = 0.5x + 7300, and the revenue function is R = (63,000x - x²). Subtracting the cost function from the revenue function gives us the profit function: P = R - C. Simplifying this equation yields P = (63,000x - x²) - (0.5x + 7300), which can be further simplified to P = 63,000x - x² - 0.5x - 7300.

To determine the intervals on which the profit function is increasing and decreasing, we analyze the behavior of the profit function with respect to changes in x. By examining the coefficient of the x² term, which is negative (-1), we can conclude that the profit function is a downward-opening parabola. Therefore, the profit function will be decreasing when x is within certain intervals. Conversely, the profit function will be increasing in other intervals.

To find the number of hamburgers needed to obtain maximum profit, we need to identify the point at which the profit function transitions from decreasing to increasing. This occurs at the vertex of the parabola, which represents the maximum point. In this case, the maximum profit occurs at the value of x where the profit function changes from decreasing to increasing. Therefore, the correct answer is "Because the function changes from decreasing to increasing at this value of x, the maximum profit occurs at this value."

To evaluate the surface integral ∬S F ⋅ dS, we need to compute the dot product of the vector field F = ⟨2xy, z=y^2, z^2⟩ with the outward unit normal vector dS for each surface element on S and then integrate over the entire surface.

The closed surface S consists of the bounded cylinder x^2 + y^2 = 4, 0 ≤ z ≤ 3, along with the disks on the top (z = 3) and bottom (z = 0).

The outward unit normal vector dS for the curved surface of the cylinder is given by dS = ⟨2x, 2y, 0⟩, and for the top and bottom disks, the normal vectors are ⟨0, 0, 1⟩ and ⟨0, 0, -1⟩, respectively.

Now, we calculate the dot product of F with dS for each surface element and integrate over the surface. The dot product F ⋅ dS is given by:

F ⋅ dS = 2xy(2x) + y^2(2y) + z^2(0) = 4x^2y + 2y^3

Integrating F ⋅ dS over the curved surface of the cylinder, we use cylindrical coordinates where x = 2cosθ, y = 2sinθ, and z ranges from 0 to 3. The integral becomes:

∫∫(cylinder) (4x^2y + 2y^3) dS = ∫∫(cylinder) (4(2cosθ)^2(2sinθ) + 2(2sinθ)^3) (2dθdz) = ∫(0 to 3) ∫(0 to 2π) (16cos^2θsinθ + 16sin^3θ) dθdz

Evaluating the above integral, we get:

∫(0 to 3) ∫(0 to 2π) (16cos^2θsinθ + 16sin^3θ) dθdz = 36π

Therefore, the surface integral ∬S F ⋅ dS evaluates to 36π.

The term "average" in statistics refers to a measure that summarizes the central tendency of a data set. Another term that could be used in place of "average" is "mean.  Average plays a crucial role in statistics as it provides a summary measure of central tendency.

The term "average" in statistics refers to a measure that represents the central tendency of a data set. It is commonly used to summarize and describe the typical value or typical level of a particular variable within a population or sample.

The role of the term "average" is to provide a single value that represents the collective information of the data set. It helps in simplifying and summarizing complex data by providing a measure that is representative of the entire distribution. It allows for comparisons, analysis, and inference based on a single value rather than considering each individual data point.

However, it's important to note that depending on the context and the nature of the data, alternative measures of central tendency may be more appropriate than the "average." For example, if the data set contains outliers or is heavily skewed, the median or mode might be better indicators of the typical value.

In summary, the term "average" plays a crucial role in statistics as it provides a summary measure of central tendency. However, it is important to consider the specific characteristics of the data set and potentially use alternative measures when necessary.

The area bounded by the graphs of the given equations over the interval -3 ≤ x ≤ 0 is 81 square units.

To find the area bounded by the graphs of the equations y = x² - 18 and y = 0 over the interval -3 ≤ x ≤ 0, we need to calculate the definite integral of the difference between the two functions over that interval.

The area can be calculated as follows:

Area = ∫[from -3 to 0] (x² - 18) dx

Integrating the function x² - 18 with respect to x gives us:

Area = [x³/3 - 18x] [from -3 to 0]

Substituting the upper and lower limits into the antiderivative, we get:

Area = [(0³/3 - 18(0)) - ((-3)³/3 - 18(-3))]

Simplifying further:

Area = [0 - (27/3 + 54)]

Area = -27 - 54

Area = -81 square units

Since the area cannot be negative, the absolute value of the calculated area is 81 square units.

The value of the definite integral ∫ [sinx+cosx]dx over the interval 0 to 2π, where [] represents the greatest integer function, is equal to 2.

The greatest integer function [x] returns the largest integer less than or equal to x. To evaluate the given integral, we need to split the interval [0, 2π] into subintervals where the values of sinx and cosx change.

For each subinterval, we evaluate the integral of [sinx+cosx] over that interval. Since the greatest integer function only takes integer values, [sinx+cosx] will take different constant values for different subintervals.

In the interval [0, π/2), both sinx and cosx are positive, so [sinx+cosx] = 1. Therefore, the integral over this interval is equal to π/2 – 0 = π/2.

In the interval [π/2, π), sinx is positive and cosx is negative, so [sinx+cosx] = 0. The integral over this interval is 0 – (π/2) = -π/2.

In the interval [π, 3π/2), both sinx and cosx are negative, so [sinx+cosx] = -1. The integral over this interval is equal to 0 – (-π/2) = π/2.

In the interval [3π/2, 2π], sinx is negative and cosx is positive, so [sinx+cosx] = 0. The integral over this interval is (π/2) – 0 = π/2.

Adding up the integrals over each subinterval, we get (π/2) + (-π/2) + (π/2) + (π/2) = 2π/2 = 2.

The equation 4x^3 - 28x^2 + 64x - 48 = 0 has a root of multiplicity 2. To find the other two roots, we can factor out (x - r)^2, where r is the root of multiplicity 2. The roots of the equation are 1 and 4.

Given the equation 4x^3 - 28x^2 + 64x - 48 = 0, we know that it has a root of multiplicity 2. Let's denote this root by r. Then we can write the equation as:

4x^3 - 28x^2 + 64x - 48 = 4(x - r)^2(x - s) = 4(x^2 - 2rx + r^2)(x - s)

Expanding the right side and comparing coefficients with the left side, we get:

-2r + s = -7        (1)

r^2 - 2rs = 16     (2)

r^2s = 12           (3)

Since r is a root of multiplicity 2, it is a solution to the equation. We can use this to simplify the other equations. From equation (1), we get s = -7 + 2r. Substituting this into equation (2), we get r^2 - 2r(-7 + 2r) = 16, which simplifies to 4r^2 - 14r - 16 = 0. Solving this quadratic equation, we get r = 2 or r = 2 - √5/2.

We know that r is a root of multiplicity 2, so the other root must be s = 2r - 7. Substituting r = 2, we get s = -3. Therefore, the roots of the equation are 1, 2, and -3. Alternatively, substituting r = 2 - √5/2, we get s = 2 - 3√5/2. Therefore, the roots of the equation are 1, 2 - √5/2, and 2 - 3√5/2.

With initial condition, y(8) = 1 Integrating both sides, we have:

∫dy/y = ∫ dt(t2 − 16t + 55)

Taking integrals of both sides, we have:

ln|y| = 1/3t3 - 8t2 + 55t + C

where C is the constant of integration

Applying the initial condition y(8) = 1, we get:

ln|1| = 1/3(8)3 - 8(8)2 + 55(8) + C0

= 1/3(512) - 8(64) + 440 + C0

= -170

Therefore, the solution to the differential equation is given by:

ln|y| = 1/3t3 - 8t2 + 55t - 170

Taking the exponential of both sides, we have:

|y| = e^(1/3t³ - 8t² + 55t - 170)

Now, we will check the sign of y

The sign of y can be either positive or negative.

In order to decide the sign of y, we use the initial condition:

y(8) = 1

So, y(8) = |e^(1/3(8)³ - 8(8)² + 55(8) - 170)|

= |e^8|> 0

Thus, the solution is valid for all real numbers.

First, let's find the limits of integration. The curves y = x^2 and y = 8 - 7x intersect at two points. Setting them equal to each other, we have x^2 = 8 - 7x, which simplifies to [tex]x^{2}[/tex] + 7x - 8 = 0. Solving this quadratic equation, we find x = -8 and x = 1. Since we are interested in the region for x > 0, the limits of integration will be from 0 to 1.

Now, we express the equations in terms of y to determine the height of each shell. Solving y = [tex]x^{2}[/tex] for x gives x = √y. Similarly, solving y = 8 - 7x for x gives x = (8 - y) / 7. Therefore, the height of each shell is h = (8 - y) / 7 - √y. The radius of each shell is the distance from the y-axis to the curve x = 0, which is simply x = 0 or r = 0.

The differential volume of each shell is given by dV = 2πrhΔy. Substituting the expressions for r and h, we have dV = 2π(0)((8 - y) / 7 - √y)Δy. Now, we integrate the differential volume over the interval from 0 to 1: V = ∫(0 to 1)2π(0)((8 - y) / 7 - √y)dy. Simplifying the integral, we have V = 2π/7 ∫(0 to 1)((8 - y) - 7√y)dy.

Evaluating the integral, V = 2π/7 [(8y - ([tex]y^{2}[/tex]/2)) - (14/3)([tex]y^(3/2)[/tex])] evaluated from 0 to 1. After substitution and simplification, V = 2π/7 (23/6). Therefore, the volume of the solid generated by revolving the given region about the y-axis is (23π/21) cubic units.

Let A be the origin and let the y-axis be the axis of symmetry of the region R.

Since the curves of R are symmetric with respect to the y-axis, the x-coordinate of the centroid of R is 0.

So,  Qd= 2000q (where q is the demand in pounds)Also, we can express the equation as:Qd = a - bp + cp2Where a = 400 * 2000 = 800,000b = 100 * 2000 = 200,000c = 0.011 * 2000 = 22The negative sign on the b-coefficient is because the price and quantity demanded have an inverse relationship with one another.

So, the demand function for pork in pounds in the city is:q = 4,000 - 200p + 22iWhere q is the quantity demanded in pounds per week, p is the price per pound, and i is the average income in the city.

The demand function for pork is Qd = 400-100P+0.011INCOME where Qd is the tons of pork demanded in your city per week, P is the price of a pound of pork, and INCOME is the average household income in the city.

Converting tons to pounds we have, 1 ton = 2000 poundsSo, Qd= 2000q (where q is the demand in pounds). Also, we can express the equation as:Qd = a - bp + cp2 where a = 400 * 2000 = 800,000, b = 100 * 2000 = 200,000, and c = 0.011 * 2000 = 22.

The negative sign on the b-coefficient is because the price and quantity demanded have an inverse relationship with one another. So, the demand function for pork in pounds in the city is: q = 4,000 - 200p + 22i where q is the quantity demanded in pounds per week, p is the price per pound, and i is the average income in the city.The demand for pork in the city is influenced by its price and income levels.

As per the demand function equation, the higher the price of pork, the lower will be the quantity demanded, and the lower the price of pork, the higher will be the quantity demanded. Therefore, the demand curve for pork is downward-sloping, indicating the inverse relationship between price and quantity demanded of pork. The demand for pork can be predicted by considering the price and income level of people.

The demand function equation, q = 4,000 - 200p + 22i, helps in understanding how the demand for pork is influenced by its price and income level.

The quantity demand is changing at a rate of -9000 tires per week when the price per tire is increasing at a rate of 2 dollars per week and 9000 tires are sold at 63 dollars each.

Let's find the derivative of  the given equation with respect to time t:

d(P + x^2)/dt = d(144)/dt

We can rewrite the equation as:

dP/dt + 2x(dx/dt) = 0

We are given that dx/dt (the rate of change of price per tire) is 2 dollars per week. Substituting this value into the equation, we get:

dP/dt + 2x(2) = 0

Now, we need to find the value of x when P = 63 (price per tire) and x = 9 (thousands of tires sold). Substituting these values into the equation, we have:

dP/dt + 2(9)(2) = 0

Simplifying, we get:

dP/dt + 36 = 0

Therefore, the rate of change of quantity demand (dP/dt) is -36 units per week, which means the quantity demand is changing at a rate of -9000 tires per week. The negative sign indicates a decrease in demand as the price per tire increases.

To find the equilibrium point, we set the demand function D(x) equal to the supply function S(x) and solve for x: Total Income = P × 2.2255 but presently total amount cant be determined

D(x) = S(x)

[tex]64 - x^2 = 3x^2[/tex]

Rearranging the equation:

[tex]4x^2 + x^2 = 64[/tex]

Combining like terms:

[tex]5x^2 = 64[/tex]

Dividing both sides by 5:

[tex]x^2 = 64/5[/tex]

Taking the square root of both sides:

x = ±√(64/5)

Therefore, the equilibrium points are x = √(64/5) and x = -√(64/5).

b. To find the consumer surplus, we need to calculate the area between the demand curve and the equilibrium quantity. The consumer surplus is given by the integral of the demand function from 0 to the equilibrium quantity:

Substituting the demand function D(x) =[tex]64 - x^2:[/tex]

Consumer Surplus = ∫[0, x] (64 - [tex]t^2[/tex]) dt

Evaluating the integral, we get:

Consumer Surplus = [64t - (1/3)[tex]t^3[/tex]] evaluated from 0 to x

2. Continuous Money Flow:

To find the total income in 8 years using a continuous money flow with a rate of f(t) = [tex]e^{0.06t}[/tex] and a present value in 8 years with r = 10%, we can use the formula:

Total Income = Present Value × [tex]e^{(rate * time)}[/tex]

Given that the present value is the amount after 8 years and the rate is 10% (0.1) while f(t) = [tex]e^{(0.06t)}[/tex], we have:

Total Income = Present Value × [tex]e^{(0.1 × 8)}[/tex]

           = Present Value × [tex]e^{0.8}[/tex]

Now, we need to calculate e^0.8 and multiply it by the present value to obtain the total income.

For the present value, we'll assume it is denoted as P.

Total Income = P × [tex]e^{0.8}[/tex]

To find the present value in 8 years with a rate of 10%, we can use the formula for compound interest:

Present Value = Future Value / [tex](1 + r)^n[/tex]

Given that the future value is the total income after 8 years, the rate is 10% (0.1), and the number of years is 8, we have:

Present Value = Total Income / [tex](1 + 0.1)^8[/tex]

The formula involves the value of e^0.8, which is approximately 2.2255.

Total Income = P × 2.2255

This provides an equation relating the total income, present value, and the value of e^0.8. Without further information or values, we cannot determine the specific amount of total income or present value.

which is positive. Therefore, x

= 2 is a local minimum.Therefore,

the function has a local maximum at x

= -5 and a local minimum at x

= 2 in the interval \[ (-9.7) \].

The given function is \[ f(x)

=x^{3}+\/{9 x^{2}}{2}-30 x \]

use the Second Derivative Test to find the location of all local extrema in the interval, we need to follow the following steps:Step 1: Calculate the first derivative of the function f(x) using the power rule of derivatives:\[ f'(x)

= 3x^2+9x-30 \]

Step 2: Calculate the second derivative of the function f(x) using the power rule of derivatives:\[ f''(x)

= 6x+9 \]

Step 3: Find the critical points of f(x) by setting f'(x) equal to zero and solving for x:

\[ f'(x)

= 3x^2+9x-30

= 0 \]\[ \Rightarrow x^2+3x-10

= 0 \]\[ \Rightarrow (x+5)(x-2)

= 0 \]

= 2.

These critical points divide the interval \[ (-9.7) \] into three subintervals:

\[ (-9.7, -5) \], \[ (-5, 2) \], and \[ (2, 9.7) \].

Step 4: Evaluate f''(x) at each critical point. If f''(x) is positive, then the critical point is a local minimum. If f''(x) is negative, then the critical point is a local maximum. If f''(x) is zero, then the Second Derivative Test is inconclusive, and we need to use another method to determine if the critical point is a local minimum or maximum. For x

= -5,

we have f''(-5)

= -21, which is negative. The x

= -5 is a local maximum.For x

To determine the equation of the tangent plane and normal line of the given curve at the point P(2, -3, 18), we need to find the partial derivatives of the function f(x, y, z) = x^2 + y^2 - 2xy - x + 3y - z - 4.

Taking the partial derivatives with respect to x, y, and z, we have:

fx = 2x - 2y - 1

fy = -2x + 2y + 3

fz = -1

Evaluating these partial derivatives at the point P(2, -3, 18), we find:

fx(2, -3, 18) = 2(2) - 2(-3) - 1 = 9

fy(2, -3, 18) = -2(2) + 2(-3) + 3 = -7

fz(2, -3, 18) = -1

The equation of the tangent plane at P is given by:

9(x - 2) - 7(y + 3) - 1(z - 18) = 0

Simplifying the equation, we get:

9x - 7y - z - 3 = 0

To find the equation of the normal line, we use the direction ratios from the coefficients of x, y, and z in the tangent plane equation. The direction ratios are (9, -7, -1).Therefore, the equation of the normal line passing through P(2, -3, 18) is:

x = 2 + 9t

y = -3 - 7t

z = 18 - t

where t is a parameter representing the distance along the normal line from the point P.

The length of the path of c(t) over the interval 1 ≤ t ≤ 4, using high school geometry, is also 6√5 or approximately 13.42 units, consistent with the result obtained using the arc length formula.

The length of the path of c(t) = (1+2t, 2+4t) over the interval 1 ≤ t ≤ 4 can be found using the arc length formula. The main answer can be summarized as: "The length of the path is 10 units."

In more detail, to find the arc length using the formula, we can first compute the derivative of c(t) with respect to t, which gives us the velocity vector. In this case, the derivative is c'(t) = (2, 4). The magnitude of the velocity vector is the speed of the particle at any given point on the curve, which is constant in this case and equal to √(2^2 + 4^2) = √20 = 2√5.

Next, we can integrate the magnitude of the velocity vector over the interval from 1 to 4:

∫[1,4] 2√5 dt = 2√5 ∫[1,4] dt = 2√5 [t] from 1 to 4 = 2√5 (4 - 1) = 2√5 (3) = 6√5.

Hence, the length of the path of c(t) over the interval 1 ≤ t ≤ 4, using the arc length formula, is 6√5 or approximately 13.42 units.

Now, let's consider the second approach using high school geometry. We can visualize the path of c(t) as a line segment connecting two points in a Cartesian plane: (1+2(1), 2+4(1)) = (3, 6) and (1+2(4), 2+4(4)) = (9, 18). The length of this line segment can be found using the distance formula, which is the Pythagorean theorem in two dimensions.

Using the distance formula, the length of the line segment connecting these two points is √((9-3)^2 + (18-6)^2) = √(6^2 + 12^2) = √(36 + 144) = √180 = 6√5.

Therefore, the length of the path of c(t) over the interval 1 ≤ t ≤ 4, using high school geometry, is also 6√5 or approximately 13.42 units, consistent with the result obtained using the arc length formula.

the length of the arc of the function[tex]\(y = \sqrt{x}\)[/tex] from[tex]\(x = 1\) to \(x = 9\)[/tex]is approximately 8.27 units.

To find the length of the arc of the function[tex]\(y = \sqrt{x}\)[/tex] from[tex]\(x = 1\)[/tex] to [tex]\(x = 9\),[/tex] we can use the arc length formula:

[tex]\[L = \int_{x_1}^{x_2} \sqrt{1 + \left(\frac{dy}{dx}\right)^2} \, dx\][/tex]

First, let's find[tex]\(\frac{dy}{dx}\)[/tex]by differentiating[tex]\(y = \sqrt{x}\)[/tex]with respect to[tex]\(x\)[/tex]:

[tex]\[\frac{dy}{dx} = \frac{1}{2\sqrt{x}}\][/tex]

Now we can substitute this into the arc length formula:

[tex]\[L = \int_{1}^{9} \sqrt{1 + \left(\frac{1}{2\sqrt{x}}\right)^2} \, dx\][/tex]

Simplifying the expression inside the square root:

[tex]\[L = \int_{1}^{9} \sqrt{1 + \frac{1}{4x}} \, dx\][/tex]

To solve this integral, we can make a substitution by letting[tex]\(u = 1 + \frac{1}{4x}\).[/tex]Taking the derivative of[tex]\(u\)[/tex]with respect to [tex]\(x\)[/tex], we have [tex]\(du = -\frac{1}{4x^2} \, dx\).[/tex]Rearranging, we get [tex]\(-4x^2 \, du = dx\).[/tex]

Substituting these values into the integral:

[tex]\[L = \int_{1}^{9} \sqrt{u} \cdot (-4x^2 \, du) = -4 \int_{u_1}^{u_2} \sqrt{u} \, du\][/tex]

The limits of integration,[tex]\(u_1\)[/tex] and[tex]\(u_2\),[/tex]can be determined by substituting [tex]\(x = 1\)[/tex]and[tex]\(x = 9\)[/tex]into the expression for \(u\):

[tex]\(u_1 = 1 + \frac{1}{4(1)} = \frac{5}{4}\)\(u_2 = 1 + \frac{1}{4(9)} = \frac{37}{36}\)[/tex]

Now we can evaluate the integral:

[tex]\[L = -4 \int_{5/4}^{37/36} \sqrt{u} \, du\][/tex]

This integral can be solved using the power rule for integration:

[tex]\[L = -4 \left[\frac{2}{3}u^{3/2}\right]_{5/4}^{37/36}\][/tex]

Simplifying further:

[tex]\[L = -4 \left(\frac{2}{3}\right) \left[\left(\frac{37}{36}\right)^{3/2} - \left(\frac{5}{4}\right)^{3/2}\right]\][/tex]

Evaluating this expression, we find:

[tex]\[L \approx 8.27\][/tex]

Therefore, the length of the arc of the function[tex]\(y = \sqrt{x}\)[/tex] from[tex]\(x = 1\) to \(x = 9\)[/tex]is approximately 8.27 units.

The values of p for which demand is elastic are (-∞, -15/2) U (-15/2, 15/2) U (15/2, ∞). The values of p for which demand is inelastic are [-15/2, 15/2].

To determine whether demand is elastic or inelastic at different price levels, we need to analyze the price-demand equation. The elasticity of demand can be determined by evaluating the absolute value of the derivative of demand with respect to price (|dD/dp|), and comparing it to 1.

Given the price-demand equation x = 2500 - 4[tex]p^2[/tex], we need to find |dD/dp|. The derivative of demand with respect to price is dD/dp = -8p. Taking the absolute value, we have |dD/dp| = |-8p| = 8|p|.

When demand is elastic, |dD/dp| > 1. Therefore, we need to find the values of p for which 8|p| > 1. Solving this inequality, we get |p| > 1/8, which implies p < -1/8 or p > 1/8.

To summarize, the values of p for which demand is elastic are (-∞, -15/2) U (-15/2, 15/2) U (15/2, ∞). The intervals (-∞, -15/2) and (15/2, ∞) represent the values of p that make demand elastic.

On the other hand, when demand is inelastic, |dD/dp| < 1. Thus, we need to find the values of p for which 8|p| < 1. Solving this inequality, we have |p| < 1/8, which means -1/8 < p < 1/8.

In conclusion, the values of p for which demand is inelastic are [-15/2, 15/2]. This interval represents the values of p that make demand inelastic.
