Answer 1

Total surplus is the sum of producer surplus and consumer surplus. It represents the combined value that consumers and producers obtain from trading.

The demand and supply functions for a Pent Scarce two-hockey stick maker for consumer, producer and total output are given below:

g(x) = −x2 − 2tx + 851y

f(x) = 5x2 + 3x + 13 where x is the number of hundreds of hockey sticks demanded and p is the price in dollars.

Therefore, in general, consumer demand is a reflection of their income and is a measure of the level of satisfaction that individuals derive from consuming goods and services. The relationship between income and consumer demand can be direct or inverse. An increase in consumer income could lead to an increase in consumer demand if the goods and services in question are classified as normal goods, or vice versa for inferior goods.

On the other hand, producers produce goods and services that are used by consumers. As a result, the supply of goods and services is dependent on the cost of production, technology, and a variety of other factors that impact the price and quantity of goods and services supplied. Producers will attempt to supply a higher quantity of goods and services if the price is high enough to offset the cost of production and make a profit, or vice versa if the price is insufficient to cover costs.

Consumer surplus is the difference between the maximum amount a consumer is willing to pay for a good and the price they actually pay. A producer's surplus is the difference between the minimum price a producer is willing to sell a good for and the price they actually sell it for. This corresponds to the difference between total revenue and total variable cost, which is the amount of revenue left over after all variable costs have been paid.

Total surplus is the sum of producer surplus and consumer surplus. It represents the combined value that consumers and producers obtain from trading.

Consider y′′+y=0. Is y(x)=5sinx+3cosx a solution?

Answers

To determine if y(x) = 5sin(x) + 3cos(x) is a solution to the differential equation y′′ + y = 0, we need to check if substituting y(x) into the equation satisfies it.

First, let's calculate the first and second derivatives of y(x):

y'(x) = 5cos(x) - 3sin(x)

y''(x) = -5sin(x) - 3cos(x)

Substituting y(x) and its derivatives into the differential equation, we have:

(-5sin(x) - 3cos(x)) + (5sin(x) + 3cos(x)) = 0

Simplifying, we get:

0 = 0

Since the equation holds true, we can conclude that y(x) = 5sin(x) + 3cos(x) is indeed a solution to the differential equation y′′ + y = 0.

The given function is y = x³ + 3x² - 2x + 1. Here, we are supposed to find the derivative of this function using the rules including the extended power rule, the product and quotient rules and the chain rule. To find the derivative of y, we need to differentiate each term of the function separately using the rules as follows:

Extended power rule: If f(x) = xⁿ,
then f'(x) = nxⁿ⁻¹.

Product rule: If f(x) = u(x)v(x), then

f'(x) = u'(x)v(x) + u(x)v'(x).

Quotient rule:

If f(x) = u(x)/v(x), then

f'(x) = [v(x)u'(x) - u(x)v'(x)]/[v(x)]².

Chain rule: If

Given

y = x³ + 3x² - 2x + 1

Now,

y' = d/dx [x³] + d/dx [3x²] - d/dx [2x] + d/dx [1]

d/dx [x³] = 3x²

Using the product rule,

d/dx [3x²]

(c) There is a higher likelihood of a stream alongside Path B, as the contour lines show a pattern similar to that of a river or stream.

(a) To determine which path requires climbing more steeply, we need to analyze the contour lines on the map. Contour lines represent points of equal elevation. When the contour lines are closer together, it indicates a steeper slope. By comparing the contour lines along paths A and B, we can observe that the lines are closer together on Path B, suggesting a steeper climb.

(b) The path that offers a better view of the surrounding countryside can be determined by considering the elevation represented by the contour lines. Higher contour lines correspond to higher elevations. Therefore, Path B, which has higher contour lines, will likely provide a better view of the surrounding countryside compared to Path A.

(c) The likelihood of a stream alongside a path can be assessed by observing the contour lines. Contour lines that are closer together and form a pattern resembling a river or stream indicate the presence of flowing water. By examining the contour lines adjacent to paths A and B, we can determine that Path B is more likely to have a stream, as the contour lines alongside it exhibit a pattern similar to a stream.

Path B requires a steeper climb, offers a better view of the surrounding countryside, and is more likely to have a stream alongside it compared to Path A, based on the analysis of the contour map.

The focus (-8, -3) and the directrix y = -9, the standard form parabola The equation for is:

y = (1/24)[tex]x ^2[/tex] + (2/3)x - 10/3

To find the parabola equation taking into account the focus and directrix, you can use the standard form of the parabola equation.

4p(y - k) = [tex](x - h)^2[/tex]

Where (h,k) represents the vertices of the parabola and 'p' is the distance from the apex to the focal point and the distance from the apex to the directrix represents

From the information given, we know that the focus is at (-8, -3) and the guideline is the horizon y = -9.

Since the guideline is a horizontal line, the parabola opens up and down.

Let's start by finding the vertex of the parabola.

Since the vertex is halfway between the focal point and the guideline, the vertex's x-coordinate is -8, which is the same as the focal point's x-coordinate.

To find the y-coordinate of the vertex, average the y-coordinates of the focus (-3) and directrix (-9):

(-3 + (-9)) / 2 = -12 / 2 = -6

So the vertex of the parabola is (-8, -6).

Next we need to find the value of 'p' which is the distance between the vertex and the focal point or guideline.

In this case, we can find 'p' by measuring the perpendicular distance from the vertex to the directrix.

The guideline is a straight line y = -9, so the distance between the vertices (-8, -6) and the guideline is 6 units.

Now that we have vertices (-8, -6) and a "p" value of 6, we can plug these values ​​into the standard geometry equation.

4p(y - k) = [tex](x - h)^2[/tex]

4(6)(y - (-6)) = [tex](x - (-8))^2[/tex]

24(y + 6) = [tex](x + 8)^2[/tex]

Expanding further, simplification:

24y + 144 = [tex]x^2[/tex] + 16x + 64

24y = [tex]x^2[/tex] + 16x - 80

Divide the whole equation by 24:

Answers

he growth rate at t = 23 months is 112 mice/month. The correct answer is option D.

To find the growth rate at t = 23 months, we need to find the derivative of the population function P with respect to time (t) and evaluate it at t = 23.

Given the population function:

P = 100(1 + 0.2t + 0.02t^2)

Taking the derivative of P with respect to t:

dP/dt = 100(0 + 0.2 + 0.04t)

Simplifying:

dP/dt = 20 + 4t

Now, we substitute t = 23 into the derivative:

dP/dt at t = 23 = 20 + 4(23) = 20 + 92 = 112 mice/month

In a volatile housing market, the overall value of a home can be modeled by V(x) = 210x2 - 4400x + 125000, where V represents the value of the home and x represents each year after 2020. Find the vertex and
interpret what the vertex of this function means in terms of the value of the home. Show the work you completed to determine the vertex.

Answers

The maximum value of the home is $104,000, and it occurs in the year 2030, which is ten years after 2020.

To find the vertex and interpret what the vertex of the function V(x) = 210x² - 4400x + 125000 represents in terms of the value of a home.

We need to complete the square as follows:

V(x) = 210x² - 4400x + 125000V(x)

= 210(x² - 20x) + 125000V(x)

= 210(x² - 20x + 100 - 100) + 125000V(x)

= 210[(x - 10)² - 100] + 125000V(x)

= 210(x - 10)² - 21000 + 125000V(x)

= 210(x - 10)² + 104000

The vertex form of a parabola is given by y = a(x - h)² + k, where (h, k) is the vertex.

In this case a = 210, b = -4400 and c = 125000.

Using the formula:

x = -(-4400) / (2 * 210)

x = 4400 / 420

x ≈ 10.476

To find it, put that value back into an expression.

V(10.476) = 210(10.476)2 - 4400(10.476) + 125000

V(10.476) ≈ 17569.27

From the expression above, the vertex of the function V(x) = 210x² - 4400x + 125000 is (h, k) = (10, 104000).

Interpretation of vertex in terms of the value of the home:

The vertex of the function V(x) = 210x² - 4400x + 125000, (h, k) = (10, 104000) represents the maximum value of the home and the year in which the home value is highest.

Answers

The answer is  "The required Taylor Polynomial `P₅(x)` for the function `f(x) = 1 + x³` at `c = 0` is `P₅(x) = 1 + (1/2)x³`.

Given function, `f(x) = 1 + x³`

The formula for Taylor Polynomial `Pn(x)` for function `f(x)` at point `x = a` is given as:

P_n(x) = f(a) + f'(a)(x-a) + \frac{f''(a)}{2!}(x-a)^2 + \frac{f'''(a)}{3!}(x-a)^3 + ... + \frac{f^n(a)}{n!}(x-a)^n

For the given function, `f(x) = 1 + x³`, we have to find the Taylor Polynomial `P₅(x)` at `c = 0`.

First, we need to find the first five  of the function `f(x)`.

Differentiating the function `f(x) = 1 + x³` with respect to `x`, we get:

f(x) = 1derivatives + x^\Rightarrow f'(x) = 3x^2 \Rightarrow f''(x) = 6x \Rightarrow f'''(x) = 6\Rightarrow f^{(4)}(x) = 0\Rightarrow f^{(5)}(x) = 0

Substitute the values of `f(0) = 1`, `f'(0) = 0`, `f''(0) = 0`, `f'''(0) = 6`, and `f⁽⁴⁾(0) = 0` in the formula of Taylor Polynomial `P₅(x)` to get:

\begin{aligned} P_5(x) &= f(0) + f'(0)(x-0) + \frac{f''(0)}{2!}(x-0)^2 + \frac{f'''(0)}{3!}(x-0)^3 + \frac{f^{(4)}(0)}{4!}(x-0)^4 + \frac{f^{(5)}(0)}{5!}(x-0)^5 \\ &= 1 + 0(x) + \frac{0}{2}(x)^2 + \frac{6}{3!}(x)^3 + \frac{0}{4!}(x)^4 + \frac{0}{5!}(x)^5 \\ &= 1 + \frac{1}{2}x^3 \end{aligned}

Hence, the required Taylor Polynomial `P₅(x)` for the function `f(x) = 1 + x³` at `c = 0` is `P₅(x) = 1 + 0(x) + 0(x)² + (6/3!)(x)³ + 0(x)⁴ + 0(x)⁵ = 1 + (1/2)x³`.

Step-by-step explanation:

The question has given us two lines, labelled A and B, on a graph, and asked us to figure out how many solutions there are for the pair of equations of the given lines.

To do this, we have to understand what a solution for a pair of equations actually means.

When we find the solution to a system of equations (also called simultaneous equations), what we calculate are a pair of x and y-values that satisfy both equations.

This means, at the calculated point, the graphs of the equations have the same x and y-coordinates. Hence, they intersect at that point, meaning they touch and cross paths.

Therefore, to find the number of solutions for the given pair of equations, we simply have to see how many times they intersect.

As we can see from the graph, the lines intersect once, so there is one solution to the given pair of equations.

P.S.

The actual solution to the pair of equations lies at the point of their intersection. As we can see from the graph, the lines intersect at the point (1, 4) and therefore that is the solution (x =1 and y = 4).

Yes No

Answers

No, the given function y = (2/3)ex + e-2x is not a solution of the differential equation y' + 2y = 2ex.

To determine whether the given function is a solution, we need to substitute it into the differential equation and check if the equation holds true.

Taking the derivative of y with respect to x, we have y' = (2/3)ex - 2e-2x.

Substituting the values of y and y' into the differential equation, we get (2/3)ex - 2e-2x + 2((2/3)ex + e-2x) = 2ex.

Simplifying the equation further, we have (2/3)ex - 2e-2x + (4/3)ex + 2e-2x = 2ex.

Combining like terms, we get (2/3 + 4/3)ex + (-2e-2x + 2e-2x) = 2ex.

Simplifying the equation even more, we have (6/3)ex = 2ex.

This equation does not hold true for all values of x. The left-hand side is not equal to the right-hand side. Therefore, the given function is not a solution to the differential equation y' + 2y = 2ex.

In conclusion, the answer is "No," the given function is not a solution to the differential equation.

Answers

 The value of ∮ C (2xye - y^2)dx + (x^2e - y^2 - 2x^2y^2e - y^2)dy is -1/2.

(d) The given path C is closed, and it encloses a region in the xy-plane. Therefore, we can apply Green’s theorem here.

Given,

F(x, y) = ⟨2xy^2, y^3⟩

Let P(x, y) = 2xy^2 and Q(x, y) = y^3

So, ∂Q/∂x = 0 and ∂P/∂y = 4xy

Using Green's Theorem,

∮ C F . dr = ∫∫R (∂Q/∂x - ∂P/∂y) dA……(1)

Here, C consists of three line segments which are joined end to end, the first line segment is y − x = 0, 0 ≤ x ≤ 1, and the second line segment is from (1, 1) to (2, 0) along the straight line y = 2 - x, and the third line segment is from (2, 0) to (0, 0) along the x-axis.

So, let's calculate each integral separately along these three line segments: Along the first line segment,

y = x, 0 ≤ x ≤ 1
∫(0,0)C1P.dx + Q.dy= ∫01 [2x(x)^2]dx + [x^3]dy

= ∫01 2x^3 dx + x^3 dy

= ∫01 (2x^3 + x^3)dx

= ∫01 3x^3 dx

= [3/4 x^4]01

= 3/4

Along the second line segment, y = 2 - x, 1 ≤ x ≤ 2
= ∫(1,1)C2P.dx + Q.dy

= ∫21 [2x(2-x)^2]dx + [(2-x)^3]dy

= ∫21 (8x - 12x^2 + 4x^3 + (2-x)^3)dx

= ∫21 (8x - 12x^2 + 4x^3 + 8 - 12x + 6x^2 - x^3)dx

= ∫21 (3x^3 - 6x^2 - 4x + 8)dx

= [3/4 x^4 - 2x^3 - 2x^2 + 8x]21

= -7/4

Along the third line segment, y = 0, 2 ≤ x ≤ 0
∫(2,0)C3P.dx + Q.dy= ∫20 [2x(0)^2]dx + [0]dy

= 0

Using Green’s Theorem,
∮ C F . dr = ∫∫R (∂Q/∂x - ∂P/∂y) dA

= 3/4 - 7/4

= -1/2

The value of ∮ C (2xye - y^2)dx + (x^2e - y^2 - 2x^2y^2e - y^2)dy is -1/2.

The sale of a computer is £420 after a 15% reduction. What was the original price before the reduction?

Answers

Answer: £494.12

Step-by-step explanation:

Let the original price be x.

15% of the original price = 15/100 * x = 0.15x

Now, according to the problem,

Selling price of computer = £420

After a 15% reduction,

The selling price of the computer = 85% of the original price

= 85/100 * x

= 0.85x

Therefore,

0.85x = 420

x = 420/0.85

x = 494.12

Therefore, the original price of the computer before the reduction was £494.12.

An undamped mass spring system is modeled by the differential equation y′′+16y=0 a) Convert the above differential equation into a system of first order differential equation. b) If initial displacement and velocity are given as y(0)=0.1 and y′(0)=0, find the solution using matrix diagonalization method.

Answers

Answer:

Step-by-step explanation:

a) To convert the given second-order differential equation into a system of first-order differential equations, we introduce a new variable z = y'.

The first equation becomes y' = z, which represents the velocity of the mass.

Differentiating the first equation with respect to time, we get y'' = z'.

Substituting this into the second equation, we have z' + 16y = 0, which can be rewritten as z' = -16y.

Therefore, the system of first-order differential equations is:

dy/dt = z

dz/dt = -16y

b) Using the matrix diagonalization method, we rewrite the system in matrix form:

Y' = AY

where Y = [y, z]' and A is the coefficient matrix [[0, 1], [-16, 0]].

To find the solution, we diagonalize the matrix A by finding its eigenvalues and eigenvectors. Solving the characteristic equation det(A - λI) = 0, we obtain eigenvalues λ = ±4i.

For λ = 4i, the eigenvector is [i/4, 1] and for λ = -4i, the eigenvector is [-i/4, 1].

We then construct the diagonal matrix D with the eigenvalues on the diagonal: D = [[4i, 0], [0, -4i]].

The matrix of eigenvectors P = [[i/4, -i/4], [1, 1]].

Using the matrix exponential, we have Y(t) = P * exp(Dt) * P^(-1) * Y(0), where Y(0) = [0.1, 0].

Calculating the matrix exponential and evaluating Y(0), we obtain the solution:

y(t) = (e^(4it) - e^(-4it))/8

z(t) = (e^(4it) + e^(-4it))/8

Therefore, the solution to the system of differential equations with initial conditions y(0) = 0.1 and y'(0) = 0 is y(t) = (e^(4it) - e^(-4it))/8 and z(t) = (e^(4it) + e^(-4it))/8.

Find d 2y/dx 2

implicitly in terms of x and y. 5xy+sin(x)=7 d 2y/dx 2 =

Answers

To find d^2y/dx^2 implicitly in terms of x and y, we need to differentiate the given equation, which is 5xy + sin(x) = 7, twice with respect to x. The result is d^2y/dx^2 = -10y/x^2 - cos(x).

To differentiate the equation 5xy + sin(x) = 7 implicitly, we apply the chain rule and product rule.

First, differentiate both sides of the equation with respect to x:

d/dx(5xy) + d/dx(sin(x)) = d/dx(7)

5y + cos(x) = 0

Next, differentiate the equation again with respect to x:

d/dx(5y) + d/dx(cos(x)) = d/dx(0)

0 + (-sin(x)) = 0

Simplifying the second derivative, we have:

d^2y/dx^2 = -10y/x^2 - cos(x)

Therefore, the second derivative implicitly in terms of x and y is given by d^2y/dx^2 = -10y/x^2 - cos(x).

The second derivative, d^2y/dx^2, can be found implicitly by differentiating the given equation twice with respect to x. The result is d^2y/dx^2 = -10xy - cos(x).

To find the second derivative, we differentiate the given equation, 5xy + sin(x) = 7, implicitly twice with respect to x.

First, we differentiate once using the product rule and chain rule:

d/dx(5xy) + d/dx(sin(x)) = 0

5y + 5xdy/dx + cos(x) = 0

Next, we differentiate again:

d/dx(5y) + d/dx(5xdy/dx) + d/dx(cos(x)) = 0

0 + 5(dy/dx + x(d^2y/dx^2)) - sin(x) = 0

Simplifying the equation, we can solve for d^2y/dx^2:

5(dy/dx + x(d^2y/dx^2)) = sin(x)

dy/dx + x(d^2y/dx^2) = sin(x)/5

d^2y/dx^2 = (sin(x)/5 - dy/dx)/x

Finally, using the initial equation 5xy + sin(x) = 7, we substitute dy/dx to get:

d^2y/dx^2 = (sin(x)/5 - (7 - sin(x))/(5x))/x

Simplifying further gives:

d^2y/dx^2 = -10xy - cos(x)

QUESTION 1 Express the vector as a product of its length and direction. 5 12 - 71-7) 131 5 7 13 7(-1-j) 169 5 12 49 7 131 12. 5 13

Answers

The vector 5 12 - 71-7) 131 5 7 13 7(-1-j) 169 5 12 49 7 131 12 can be expressed as the product of its length and direction.

It seems that your question is asking to express several vectors as a product of their length and direction. Let's go through each vector one by one:

1.Vector (5, 12, -71, -7):

To express this vector as a product of its length and direction, we need to find the length (magnitude) of the vector and its direction (unit vector). The length of the vector can be found using the formula:

|v| = [tex]\sqrt(x^2 + y^2 + z^2)[/tex],

where (x, y, z) are the components of the vector.

Applying this formula to the given vector, we have:

|v| = [tex]\sqrt(5^2 + 12^2 + (-71)^2 + (-7)^2)[/tex]

= [tex]\sqrt(25 + 144 + 5041 + 49)[/tex]

= [tex]\sqrt(6259)[/tex]

≈ 79.11 (rounded to two decimal places).

Now, let's find the direction (unit vector) of this vector. The direction of a vector can be obtained by dividing each component by the magnitude of the vector:

u = (x/|v|, y/|v|, z/|v|).

Applying this formula to the given vector, we have:

u = (5/79.11, 12/79.11, -71/79.11, -7/79.11)

≈ (0.063, 0.152, -0.898, -0.089).

Therefore, the vector (5, 12, -71, -7) can be expressed as the product of its length (magnitude) and direction as:

79.11 * (0.063, 0.152, -0.898, -0.089).

2.Vector (131, 5, 7, 13):

Following the same steps as above, let's calculate the length (magnitude) and direction (unit vector) of this vector.

|v| = [tex]\sqrt(131^2 + 5^2 + 7^2 + 13^2)[/tex]

=[tex]\sqrt(17161 + 25 + 49 + 169)[/tex]

= [tex]\sqrt(17404)[/tex]

≈ 131.94 (rounded to two decimal places).

u = (131/131.94, 5/131.94, 7/131.94, 13/131.94)

≈ (0.994, 0.038, 0.053, 0.098).

Therefore, the vector (131, 5, 7, 13) can be expressed as the product of its length (magnitude) and direction as:

131.94 * (0.994, 0.038, 0.053, 0.098).

3.Vector (7, -1 -j, 169, 5, 12, 49, 7):

It seems that this vector has complex components (with the presence of "-j"). To express this vector as a product of its length and direction, we need to find the magnitude of the vector and its direction.

|v| = [tex]\sqrt((7^2) + (-1 - j)^2 + 169^2 + 5^2 + 12^2 + 49^2 + 7^2)[/tex]

= [tex]\sqrt(49 + 1 + 2j + j^2 + 169 + 25 + 144 + 2401 + 49)[/tex]

= [tex]\sqrt(2839 + 2j)[/tex]

≈[tex]\sqrt(2839)[/tex] * [tex]\sqrt(1 + 2j/2839)[/tex] (approximation)

The direction (unit vector) can be obtained by dividing each component by the magnitude:

u = (7/|v|, (-1 - j)/|v|, 169/|v|, 5/|v|, 12/|v|, 49/|v|, 7/|v|).

Therefore, the vector (7, -1 -j, 169, 5, 12, 49, 7) can be expressed as the product of its length and direction as:

[tex]\sqrt(2839)[/tex] * [tex]\sqrt(1 + 2j/2839)[/tex] * (7/|v|, (-1 - j)/|v|, 169/|v|, 5/|v|, 12/|v|, 49/|v|, 7/|v|).

It's important to note that for the third vector, I've made an approximation for simplicity since the square root of a complex number can be challenging to represent precisely.

a) The process described in part (a) is not a correct process for solving the given exact differential equation. The errors in the process can be identified as follows:

1. Rewriting the equation: The equation is rewritten as (3x² - 2xy + 3y²) dy = (y² - 6xy - 3x²) dx. This step is incorrect because the original equation is already in the correct form for an exact differential equation.

2. Integrating both sides separately: Integrating the equation separately with respect to y and x is not a valid approach for solving an exact differential equation. In an exact differential equation, the equation is already the result of taking the partial derivatives of a potential function, and integrating both sides as separate functions will not yield the correct solution.

3. Ignoring terms with y in the second integrand: By ignoring the terms with y in the second integrand, the process disregards an important part of the equation, leading to an incorrect solution.

The correct method for solving an exact differential equation involves finding a potential function and using it to derive the solution.

b) To solve the given exact differential equation, we follow the correct process:

The given equation is:

(3x² - 2xy + 3y²) dy = (y² - 6ay - 3x²) dx

To check if the equation is exact, we calculate the partial derivatives of the expression with respect to x and y:

∂M/∂y = 6y - 2x

∂N/∂x = -6y - 2x

Since ∂M/∂y is not equal to ∂N/∂x, the equation is not exact.

To make the equation exact, we multiply it by an integrating factor. The integrating factor is defined as the exponential of the integral of the difference between the coefficients of dy and dx:

[tex]\[ \mu = e^{\int \frac{\frac{\partial N}{\partial x} - \frac{\partial M}{\partial y}}{N} \, dx} = e^{\int \frac{-4x}{-6y - 2x} \, dx} = e^{\frac{2x}{3y}} \][/tex]

Multiplying both sides of the equation by the integrating factor, we get:

[tex]\[ e^{\frac{2x}{3y}}(3x^2 - 2xy + 3y^2) \, dy = e^{\frac{2x}{3y}}(y^2 - 6ay - 3x^2) \, dx \][/tex]

Now, the equation becomes exact. We can find the potential function by integrating the terms with respect to the appropriate variables.

Integrating the left-hand side with respect to y:

[tex]\[ \int e^{\frac{2x}{3y}} (3x^2 - 2xy + 3y^2) \, dy = \int (3x^2e^{\frac{2x}{3y}} - 2xye^{\frac{2x}{3y}} + 3y^2e^{\frac{2x}{3y}}) \, dy \][/tex]

This integration yields:

[tex]\[3x^2ye^{\frac{{2x}}{{3y}}} + 3e^{\frac{{2x}}{{3y}}} + y^3e^{\frac{{2x}}{{3y}}} + C(x) = F(x, y)\][/tex]

Here, C(x) is an arbitrary function of x.

Now, we differentiate the result with respect to x and equate it to the right-hand side of the original equation to find C(x):

[tex]\[ \frac{{\partial F(x, y)}}{{\partial x}} = \frac{{\partial (3x^2ye^{\frac{{2x}}{{3y}}}) + 3e^{\frac{{2x}}{{3y}}} + y^3e^{\frac{{2x}}{{3y}}} + C(x)}}{{\partial x}} \][/tex]

Comparing this with (y² - 6ay - 3x²), we can equate the coefficients:

∂F(x, y)/∂x = -3x²

[tex]\[ \frac{{\partial(3x^2ye^{\frac{{2x}}{{3y}}}) + 3e^{\frac{{2x}}{{3y}}} + y^3e^{\frac{{2x}}{{3y}}} + C(x)}}{{\partial x}} = -3x^2 \][/tex]

By differentiating and solving the above equation, we can find C(x).

Finally, the solution to the exact differential equation will be given by F(x, y) = constant, where F(x, y) is the potential function obtained by integrating the original equation.

Answers

In the first limit, lim(x->0) (1 - cos(2x))/(7x), the type of indeterminate form is 0/0. By applying L'Hopital's Rule, we can find the limit by differentiating the numerator and denominator with respect to x.

(a) For the limit lim(x->0) (1 - cos(2x))/(7x), we have an indeterminate form of 0/0. To apply L'Hopital's Rule, we differentiate the numerator and denominator with respect to x:

Numerator: d(1 - cos(2x))/dx = 0 - (-2sin(2x)) = 2sin(2x)

Denominator: d(7x)/dx = 7

Now, we evaluate the limit of the ratio of the derivatives:

lim(x->0) (2sin(2x))/7

Since sin(2x)/x approaches 1 as x approaches 0, we can substitute the limit:

lim(x->0) (2sin(2x))/7 = (2 * 1)/7 = 2/7

Therefore, the limit of (1 - cos(2x))/(7x) as x approaches 0 is 2/7.

(b) For the limit lim(x->∞) √(ln(x)), we have an indeterminate form of ∞ * 0. However, L'Hopital's Rule is not applicable in this case as it is specifically used for the indeterminate forms 0/0 and ∞/∞. Therefore, we cannot evaluate this limit using L'Hopital's Rule. Other methods, such as using properties of limits or algebraic manipulations, may be needed to find the limit in this case.

Answers

The problem involves finding the triple integral of the function z over a solid region E in the first octant. The triple integral to find the volume of the solid E is ∫∫∫_E z dv = ∫₀⁻⁰ ∫₀⁽⁹²⁾ ∫₋√(⁸¹⁻y²) √(⁸¹⁻y²) z dx dy dz.

To set up the triple integral, we need to consider the limits of integration for each variable. The given solid is bounded by the cylinder y² + 2² = 81, which can be rewritten as y² = 77. This means that the values of y will range from -√77 to √77. The planes z = 0 and z = -0 indicate that the z-values will range from 0 to -0, which means that the z-limits are fixed. Finally, the plane y = 92 limits the y-values to be from 0 to 92.

To set up the triple integral, we use the differential volume element dv = dz dy dx. The limits of integration for z are from 0 to -0, the limits for y are from 0 to 92, and the limits for x depend on the equation of the cylinder. Since the cylinder is symmetric about the y-axis, the limits for x can be taken from -√(81 - y²) to √(81 - y²).

Therefore, the triple integral to find the volume of the solid E is ∫∫∫_E z dv = ∫₀⁻⁰ ∫₀⁽⁹²⁾ ∫₋√(⁸¹⁻y²) √(⁸¹⁻y²) z dx dy dz.

13. Find the limit. sine lim 8-00+ tane

Answers

The limit of sin(tan(t)) as t approaches positive infinity is undefined.

To find the limit of sin(tan(t)) as t approaches positive infinity, we need to evaluate the behavior of the function as t becomes arbitrarily large.

The function tan(t) oscillates between positive and negative infinity as t approaches positive infinity. Since the sine function, sin(t), oscillates between -1 and 1, the composition sin(tan(t)) does not have a well-defined limit as t goes to infinity. This is because the oscillations of the tangent function cause the output of the sine function to constantly change between -1 and 1.

Therefore, the limit of sin(tan(t)) as t approaches positive infinity is undefined. It does not converge to a specific value. In cases like this, where the function oscillates or exhibits unpredictable behavior, the limit is said to be "undefined" or "does not exist."
