Answer:
Step-by-step explanation:
a) To find the recurrence relation for the problem, let's denote the population at the (n+1)th year as P(n+1). According to the given information, the increase in population at the (n+1)th year is equal to the average population of the previous two years plus n-th power of 2.
Based on this, we can write the recurrence relation as follows:
P(n+1) = (P(n) + P(n-1)) / 2 + n²
b) Now, let's find the explicit solution for the population at the n'th year, given the initial two years of population as 0 and 1.
To find the explicit solution, we need to expand the recurrence relation until we reach the base cases or initial conditions.
Let's start expanding the relation:
For n = 0:
P(1) = (P(0) + P(-1)) / 2 + 0²
Since P(-1) is not defined, we can use the initial condition P(0) = 0.
P(1) = (0 + P(-1)) / 2 + 0
P(1) = P(-1) / 2
For n = 1:
P(2) = (P(1) + P(0)) / 2 + 1²
Since we know P(1) = 1 and P(0) = 0, we can substitute these values:
P(2) = (1 + 0) / 2 + 1
P(2) = 1/2 + 1
P(2) = 3/2
For n = 2:
P(3) = (P(2) + P(1)) / 2 + 2²
Using the values we found earlier:
P(3) = (3/2 + 1) / 2 + 4
P(3) = 5/4 + 4
P(3) = 9/4 + 16/4
P(3) = 25/4
Continuing this process, we can find the explicit solution for the population at the n'th year.
Based on the pattern observed, we can express the explicit solution as follows:
P(n) = f(n)
where f(n) is a function defined recursively as:
f(0) = 0
f(1) = 1
f(n) = (f(n-1) + f(n-2)) / 2 + n²
Therefore, the explicit solution for the population at the n'th year is given by the function f(n) defined recursively as above.

use cylindrical coordinates to find the volume of the region bounded by the plane z=2√10 and the hyperboloid z=√4 x^2 y^2
The triple integral to find the volume of the region bounded by the plane [tex]z = 2\sqrt{10[/tex] and the hyperboloid [tex]z = \sqrt{4x^2 + y^2}[/tex] in cylindrical coordinates is [tex]\frac{400\pi}{3}[/tex] approximately equal to 418.88
To find the volume of the region bounded by the plane z = 2√10 and the hyperboloid [tex]z = \sqrt{4x^2 + y^2}[/tex], we can use cylindrical coordinates. In cylindrical coordinates, we have three variables: r (radius), θ (angle), and z (height).
The conversion from Cartesian coordinates to cylindrical coordinates is given by:
x = rcos(θ)
y = rsin(θ)
z = z
Let's begin by finding the intersection points of the plane and the hyperboloid:
Setting [tex]z = 2\sqrt{10}[/tex] in the hyperboloid equation:
[tex]2\sqrt{10}= \sqrt{4x^2 + y^2}[/tex]
Squaring both sides:
[tex]40 = 4x^2 + y^2[/tex]
Dividing both sides by 4:
[tex]10 = x^2 + 0.25y^2[/tex]
Now we have an equation in terms of x and y that describes the ellipse formed by the intersection of the plane and the hyperboloid.
To find the bounds for r, we need to determine the radius of this ellipse. We can do this by finding the maximum value of x and y on the ellipse.
Since [tex]x^2 + 0.25y^2 = 10[/tex], we can rearrange the equation to solve for [tex]x^2[/tex]:
[tex]x^2 = 10 - 0.25y^2[/tex]
The maximum value of x occurs when y = 0, so substituting y = 0 into the equation above:
[tex]x^2 = 10 - 0.25(0)^2\\x^2 = 10[/tex]
Taking the square root:
x = ±[tex]\sqrt{10}[/tex]
Similarly, the maximum value of y occurs when x = 0, so substituting x = 0 into the equation [tex]x^2 + 0.25y^2 = 10[/tex]:
[tex]0 + 0.25y^2 = 10\\y^2 = 40\\[/tex]
y = ±[tex]\sqrt{40}[/tex] = ±2[tex]\sqrt{10}[/tex]
Thus, the bounds for r are from 0 to √10.
Next, let's find the bounds for θ. Since we are considering the entire region bounded by the plane and the hyperboloid, θ will vary from 0 to 2π.
Finally, for the bounds of z, we can see that the plane z = 2[tex]\sqrt{10}[/tex] gives us the upper bound for z. Hence, z will vary from 0 to 2[tex]\sqrt{10}[/tex].
Now we have all the necessary bounds to set up the volume integral. The volume can be calculated using the triple integral in cylindrical coordinates:
V = ∫∫∫ r dz dr dθ
The limits for integration are as follows:
θ: 0 to 2π
r: 0 to [tex]\sqrt{10}[/tex]
z: 0 to 2[tex]\sqrt{10}[/tex]
Therefore, the volume can be calculated as:
[tex]V = \int_0 ^{2\pi}{ \int_0^{ \sqrt{10}} \int_0^{2\sqrt{10}}{ r \, dz }\, dr \, }d\theta[/tex]
[tex]V= 400\pi/3 = 418.88[/tex]
Therefore, the triple integral to find the volume of the region bounded by the plane [tex]z = 2\sqrt{10[/tex] and the hyperboloid [tex]z = \sqrt{4x^2 + y^2}[/tex] in cylindrical coordinates is [tex]\frac{400\pi}{3}[/tex] approximately equal to 418.88

Find the area bounded by the t-axis and y(t)=sin(t/18) between t=2 and 7. Accurately sketch the area.
The area bounded by the t-axis and the curve y(t) = sin(t/18) between t = 2 and t = 7 can be found by integrating absolute value of function over that interval. The integral represents the area under the curve.
To calculate the area, we can set up the integral as follows:
A = ∫[2, 7] |sin(t/18)| dt
The absolute value is used to ensure that the area is always positive. Integrating the absolute value of sin(t/18) over the interval [2, 7] will give us the area bounded by the curve and the t-axis.
To evaluate this integral, we can use appropriate integration techniques or numerical methods such as numerical approximation or numerical integration.
To accurately sketch the area, we can plot the curve y(t) = sin(t/18) on a graph with the t-axis and shade the region between the curve and the t-axis between t = 2 and t = 7. The shaded region represents the area bounded by the curve and the t-axis.

The Demand Function And The Average Cost Function Of A Firm Are As Follows: 90-9 P= 2 AC =q²-8q+57 + a) Find The Amount Of Output That Maximize The Total Revenue b) Based On Answer a), Find The Maximum Total Revenue c) Find The Amount Of Output That Minimizes The Marginal Cost d) Find The Amount Of Output That Maximizes Profits
The demand function tells us how much the firm can sell at a given price. The marginal cost function tells us how much it costs the firm to produce one more unit.
The amount of output that maximizes total revenue is the amount of output where the marginal revenue equals zero. This is because the marginal revenue is the additional revenue that the firm earns by selling one more unit. If the marginal revenue is zero, then the firm is not earning any additional revenue by selling one more unit, so it cannot increase its total revenue by selling more units.
The maximum total revenue is equal to the total revenue at the output level where the marginal revenue equals zero. In this case, the maximum total revenue is 81 units.
The amount of output that minimizes marginal cost is the amount of output where the marginal cost is equal to the average cost. This is because the marginal cost is the cost of producing one more unit, and the average cost is the cost of producing all units. If the marginal cost is equal to the average cost, then the firm is not making any profit or loss by producing one more unit, so it cannot reduce its costs by producing more units.
The amount of output that maximizes profits is the amount of output where profits are equal to zero. This is because profits are the difference between total revenue and total cost. If profits are equal to zero, then the firm is not making any profit or loss, so it cannot increase its profits by producing more units.
In this case, the amount of output that maximizes profits is 7 units.

The function attains its absolute minimum at the critical point (0,0), and it attains its absolute maximum at the point (2,0) and (-2,0)
The given function is f(x,y)=4x+2y subjected to the domain x^2+y^2≤4. To find absolute minimum and absolute maximum, we need to compute its critical points, then we will compare the function's values on these critical points and boundary points of the domain. It's not difficult to realize that the domain of the function is the closed disk centered at (0,0) with radius 2. The critical points of f(x,y) are obtained by taking the partial derivatives of the function with respect to x and y and equating them to zero. [tex]$$\frac{\partial f}{\partial x}=4 $$ $$\frac{\partial f}{\partial y}=2 $$[/tex]
Equating both these to zero, we get that the critical point is (0,0).Since this point lies on the boundary of the given domain, we will compare the function's values on this point to those on the boundary.
Since f(x,y) increases as we move away from (0,0) in any direction, Therefore, we can conclude that the function attains its absolute minimum at the critical point (0,0), and it attains its absolute maximum at the point (2,0) and (-2,0).

(c) f(g(x)) = 1/(3x + 5), applying the function f to g(x).
(d) g(f(x)) = 3/x + 5, applying the function g to f(x).
n part (a), we find the product of the functions f(x) and g(x). Since f(x) = 1/x and g(x) = 3x + 5, we can multiply them to get f(x)g(x) = (1/x)(3x + 5). Simplifying this expression gives us 3 + 5/x.
In part (b), we need to divide f(x) by g(x). By dividing 1/x by (3x + 5), we get f(x)/g(x) = 1/(x(3x + 5)). This is the quotient of the two functions.
In part (c), we apply the function f to g(x). Substituting g(x) = 3x + 5 into f(x), we obtain f(g(x)) = f(3x + 5) = 1/(3x + 5). This means we substitute g(x) into f(x) and simplify the expression.

Determine on what point(s) the graph of f(x) = x3 −3x2 is

give the interval(s) where f(x) is concave up and the interval(s)
of concave down.
The graph of the function f(x) = x^3 - 3x^2 changes its concavity at x = 0 and x = 2/3. The function is concave up on the intervals (-∞, 0) and (2/3, ∞), and concave down on the interval (0, 2/3).
To determine where the graph of f(x) changes its concavity, we need to find the points where the second derivative of f(x) changes sign. Let's start by finding the second derivative of f(x):f'(x) = 3x^2 - 6x,f''(x) = 6x - 6.The second derivative is a linear function, and it changes sign at x = 1. This means that the concavity changes at x = 1. Now, we can look for other points where the second derivative may change sign by solving f''(x) = 0:6x - 6 = 0,x = 1
So, x = 1 is the only critical point where the second derivative is zero. However, we also need to check the concavity around x = 1. To do this, we can evaluate the second derivative at points near x = 1. Taking a value less than 1, let's say x = 0.5:f''(0.5) = 6(0.5) - 6 = -3.The second derivative is negative, indicating that the graph is concave down around x = 1. Similarly, for x = 1.5:f''(1.5) = 6(1.5) - 6 = 3.The second derivative is positive, indicating that the graph is concave up around x = 1.Therefore, the graph of f(x) = x^3 - 3x^2 changes its concavity at x = 0 and x = 2/3. It is concave up on the intervals (-∞, 0) and (2/3, ∞), and concave down on the interval (0, 2/3).

Compute the gradient of the following function and evaluate it at the given point P g(x,y)=x² −4x² y−5xy² ;P(−2,1)
The gradient of `g(x,y)` is `[7, -36]` evaluated at point `P(-2,1)`.
Given function: `g(x,y) = x² − 4x²y − 5xy²`.
To find the gradient of the given function, we need to find its partial derivatives with respect to x and y.
Step-by-step explanation: Let's find the partial derivative of `g(x,y)` with respect to `x`.
To do that, differentiate `g(x,y)` with respect to `x` by treating `y` as a constant.
g(x,y) = `x² − 4x²y − 5xy²`∂g/∂x = `2x − 8xy − 5y²`
This is the partial derivative of `g(x,y)` with respect to `x`.
Let's now find the partial derivative of `g(x,y)` with respect to `y`. To do that, differentiate `g(x,y)` with respect to `y` by treating `x` as a constant.
g(x,y) = `x² − 4x²y − 5xy²`∂g/∂y = `-4x² − 10xy`
This is the partial derivative of `g(x,y)` with respect to `y`.
The gradient of `g(x,y)` is the vector of its partial derivatives.
Therefore, the gradient of `g(x,y)` is given by:
grad `g(x,y)` = ∇`g(x,y)` = [∂g/∂x, ∂g/∂y]
On substituting the partial derivatives of `g(x,y)` obtained earlier, we get:
grad `g(x,y)` = ∇`g(x,y)` = [2x − 8xy − 5y², -4x² − 10xy]
Now, we need to evaluate the gradient of `g(x,y)` at point `P(-2, 1)`.
Substitute `x = -2` and `y = 1` in the gradient we obtained to find the gradient at `P(-2,1)`.
grad `g(-2,1)` = [2(-2) − 8(-2)(1) − 5(1)², -4(-2)² − 10(-2)(1)]
grad `g(-2,1)` = [-4 + 16 - 5, -16 + (-20)]
grad `g(-2,1)` = [7, -36]
Hence, the gradient of `g(x,y)` is `[7, -36]` evaluated at point `P(-2,1)`.

Find an explicit solution to the following initial value problem using an integrating factor. Identify any singular points that may exist. dy/dx + 3y/x + 2 = 3x: y(1) = 1
The integrating factor becomes infinite at x = 0.
The differential equation that has to be solved is given by:
dy/dx + 3y/x + 2 = 3x
The integrating factor is given by:
μ(x) = e^(∫(3/x)dx)
integrating both sides:
∫(3/x)dx = 3 ln(x) + c
Therefore, the integrating factor is given by:
μ(x) = e^(3 ln(x) + c) = e^(ln(x^3)) * e^(c) = k x^3
where k = e^c.
Substituting the value of the integrating factor into the given differential equation:
k x^3 dy/dx + 3k x^2 y + 2k x^3
= 3k x^4
Simplifying the above equation:
x^3 dy/dx + 3 x^2 y + 2x^3
= 3x^4
Rearranging the above equation:
dy/dx + (3/x) y = x
Multiplying the equation by the integrating factor:
k x^3 dy/dx + 3k x^2 y = 3k x^4
The left-hand side of the above equation can be written as d/dx (k x^3 y)
which gives the solution to the differential equation as:
k x^3 y = ∫3k x^4 dx = (3k/5) x^5 + c
Therefore, the solution to the given differential equation is given by:
y = ((3/5) x^2 + c/x^3)
where c is the constant of integration.
The initial condition is y(1) = 1.
Substituting the above initial condition into the solution of the differential equation:
1 = ((3/5) * 1^2 + c/1^3)
Solving for c,
c = 2/5
Therefore, the explicit solution to the given differential equation with the given initial condition is given by:
y = ((3/5) x^2 + (2/5)/x^3)

Use the integral test to see if series convergee or diverges. 1. ∑n=1[infinity]n2e−n3.
In this question, the series ∑(n=1 to infinity) n^2e^(-n^3) converges by the integral test.
To determine if the series ∑(n=1 to infinity) n^2e^(-n^3) converges or diverges, we can use the integral test.
The integral test states that if f(x) is a continuous, positive, and decreasing function on the interval [1, infinity) and the function f(n) corresponds to the terms of the series, then the series converges if and only if the improper integral ∫(1 to infinity) f(x) dx converges.
In this case, we have f(x) = x^2e^(-x^3). To apply the integral test, we need to check if f(x) satisfies the conditions.
f(x) is continuous, positive, and decreasing for x ≥ 1:
The function x^2 is always positive for x ≥ 1.
The exponential function e^(-x^3) is positive for all x.
Taking the derivative of f(x), we have f'(x) = 2xe^(-x^3) - 3x^4e^(-x^3). Since x ≥ 1, f'(x) ≤ 0, indicating that f(x) is decreasing.
Evaluate the integral ∫(1 to infinity) f(x) dx:
∫(1 to infinity) x^2e^(-x^3) dx = (-1/3) e^(-x^3) from 1 to infinity.
Taking the limit as the upper bound approaches infinity:
lim (b→∞) [(-1/3) e^(-b^3) - (-1/3) e^(-1^3)].
Since e^(-b^3) approaches 0 as b approaches infinity, the limit simplifies to (-1/3) e^(-1^3) = (-1/3) e^(-1).
Now, if the integral converges, the series converges. If the integral diverges, the series diverges.
Since the integral ∫(1 to infinity) f(x) dx converges to a finite value (-1/3) e^(-1), we can conclude that the series ∑(n=1 to infinity) n^2e^(-n^3) converges.

the initial value problem is: dI/dt = 0.0001 * I(t) * (2000 - I(t)), with the initial condition I(0) = 20. To find the solution, we need to solve this differential equation.
Let I(t) denote the number of infected individuals at time t. Based on the problem's description, the rate of change of the infected population is given by the equation dI/dt = k * I(t) * (2000 - I(t)), where k is the proportionality constant and (2000 - I(t)) represents the non-infected population.

The three numbers that satisfy the given conditions (between 20 and 40 and present in both sequences) are 21, 23, and 25.
To find the numbers that are in both sequences and between 20 and 40, we need to solve the inequalities based on the given nth term expressions.
For the first sequence: nth term = 2n + 3
We set up the inequality:
20 ≤ 2n + 3 ≤ 40
Subtracting 3 from all parts of the inequality, we get:
17 ≤ 2n ≤ 37
Dividing all parts of the inequality by 2, we have:
8.5 ≤ n ≤ 18.5
Since n represents the position or index of the term in the sequence, we need to find the corresponding numbers by substituting the values of n into the nth term expression.
For n = 9, we have:
2n + 3 = 2(9) + 3 = 18 + 3 = 21
For n = 10, we have:
2n + 3 = 2(10) + 3 = 20 + 3 = 23
For n = 11, we have:
2n + 3 = 2(11) + 3 = 22 + 3 = 25
Therefore, the three numbers that satisfy the given conditions (between 20 and 40 and present in both sequences) are 21, 23, and 25.

The critical numbers of the function are x = 2 and x = 8.
The smaller critical number is x = 2.
The larger critical number is x = 8.
To find the critical numbers of the function f(x) = 2x³ - 30x² + 96x - 10, we need to take the derivative of the function and set it equal to zero.
Calculate the derivative of f(x):
f'(x) = 6x² - 60x + 96
Set the derivative equal to zero and solve for x:

A student solved the following related rates problem correctly: "A spherical hot-air balloon is being inflated at a rate of 10 cubic meters per hour. When the surface area of the balloon is 100 meters squared, how fast is the radius changing?" The student correctly found that dr/dt = 1/ 10
but isn't sure what the units are or what this means in the context of this problem. (a) What are the correct units for dr/dt ? (b) Write an interpretation of what the numerical answer and units mean in the context of this problem. Be sure to write in complete sentences.
The correct units for dr/dt are meters per hour (m/h) in a related rates problem involving a spherical hot-air balloon. The numerical answer of 1/10 means the radius increases by 1/10 of a meter per hour when the surface area is 100 square meters.
(a) The correct units for dr/dt can be found using the units of the given information. The rate of inflation is given in cubic meters per hour, which means the units of volume are meters cubed (m^3) and the units of time are hours (h). The surface area of the balloon is given in square meters (m^2). The formula for the surface area of a sphere is A = 4πr^2, where r is the radius. Taking the derivative of both sides with respect to time, we get:
dA/dt = 8πr dr/dt
Solving for dr/dt, we get:
dr/dt = (dA/dt)/(8πr)
Substituting the given values, we get:
dr/dt = (10 m^3/h)/(8πr)
Therefore, the units of dr/dt are meters per hour (m/h).
(b) The numerical answer of dr/dt = 1/10 means that the radius of the spherical hot-air balloon is increasing at a rate of 1/10 meters per hour when the surface area of the balloon is 100 square meters. The units of meters per hour (m/h) indicate the rate of change of the radius over time. In other words, for every hour that passes, the radius of the balloon increases by 1/10 of a meter. This is because the balloon is being inflated at a constant rate of 10 cubic meters per hour, and as the volume of the balloon increases, so does its radius.

0.16ft
60 degrees
A unit vector orthogonal to both u and v is approximately (0.628, 0.387, 0.676). The magnitude of the torque on the crankshaft is 120√3 lb-ft.
To find a unit vector that is orthogonal (perpendicular) to both vectors u and v, we can calculate the cross product of u and v, and then normalize the resulting vector.
Given vectors u = (-8, -6, 4) and v = (12, -16, -2), the cross product can be found as follows:
u x v = (u2v3 - u3v2, u3v1 - u1v3, u1v2 - u2v1)
= ((-6)(-2) - (4)(-16), (4)(12) - (-8)(-2), (-8)(-16) - (-6)(12))
= (-12 + 64, 48 - 16, 128 - 72)
= (52, 32, 56)
To normalize the resulting vector, we calculate its magnitude and divide each component by the magnitude:
Magnitude = √[tex](52^2 + 32^2 + 56^2)[/tex]
= √(2704 + 1024 + 3136)
= √6864
≈ 82.8
The unit vector orthogonal to u and v is:
(52/82.8, 32/82.8, 56/82.8) ≈ (0.628, 0.387, 0.676)
To find the magnitude of the torque on the crankshaft, we can use the formula:
Torque = Force * Radius * sin(θ)
Given:
Force (F) = 1500 lb
Radius = 0.16 ft
Angle (θ) = 60 degrees
Converting the angle to radians: θ = 60 degrees * π/180 = π/3 radians
Plugging in the values into the formula:
Torque = 1500 lb * 0.16 ft * sin(π/3)
= 1500 * 0.16 * (√3/2)

(iv) 0.01 seconds
Given that, the height in feet after t seconds is given by:
y = 42t - 16t². To find the average velocity, use the following formula:
Average velocity = Δy / ΔtWhere Δy is the change in the distance and Δt is the change in time.
(i) For t = 2 and Δt = 0.5, the average velocity can be found as:
Δy = y2 + Δt - y2

a. f(x+h):
To find f(x+h), we substitute (x+h) into the function:
f(x+h) = 9/(x+h)
b. f(x+h)−f(x):
To find f(x+h)−f(x), we substitute (x+h) and x into the function, and then subtract:
f(x+h)−f(x) = (9/(x+h)) - (9/x)
To simplify this expression, we need to find a common denominator:
f(x+h)−f(x) = (9x - 9(x+h)) / (x(x+h))
f(x+h)−f(x) = (9x - 9x - 9h) / (x(x+h))
f(x+h)−f(x) = -9h / (x(x+h))
c. [f(x+h)−f(x)]/h:
To find [f(x+h)−f(x)]/h, we divide f(x+h)−f(x) by h:
[f(x+h)−f(x)]/h = (-9h / (x(x+h))) / h
[f(x+h)−f(x)]/h = -9 / (x(x+h))

Now, let's consider the critical points of the function. To find the critical points, we need to find where the gradient of the function is zero or undefined. Since the function is defined in terms of both \(x\) and \(y\), we will find the partial derivatives with respect to \(x\) and \(y\) and set them equal to zero.
[tex]\(f_x = 2x(y-2)\)[/tex]

3. Distance between parallel planes:
The distance between two parallel planes given by the equations
Ax + By + Cz + D = 0 and Ax + By + Cz + E = 0 is:
|D − E| / √(A² + B² + C²)
Plugging in the values from the problem, we have the two planes:
4z = 6y − 2x and 6z = 1 − 3x + 9y.
Both planes are already in the form Ax + By + Cz + D = 0,
so we can read off the coefficients and plug them into the formula above:

Evaluate the difference quotient for the given function. Simplify your answer. f(x)=x+7/x+1,f(x)−f(5)/x-5
We have been given f(x) = (x+7)/(x+1) and we need to find the difference quotient given by (f(x) - f(5))/(x - 5).
First, we will calculate f(x) and f(5) and substitute in the above expression.
f(x) = (x+7)/(x+1)
f(5) = (5+7)/(5+1) = 12/6 = 2
(f(x) - f(5))/(x - 5) = {[ (x+7)/(x+1)] - 2}/(x-5)
Multiplying the numerator by (x+1),
we get:
(f(x) - f(5))/(x - 5) = [x+7 - 2(x+1)]/[(x+1) (x-5)]
Simplifying the numerator:
f(x) - f (5) = x + 7 - 2x - 2
f(x) - f (5) = -x + 5
Now, substituting these values in the original expression,
we get:
(f(x) - f(5))/(x - 5) = [(-x+5)/(x+1) (x-5)]
The final answer can be written as:
-x + 5 / (x² - 4x - 5)
To calculate the difference quotient for the given function f(x) = (x+7)/(x+1), we need to substitute the values of x and 5 in the expression (f(x) - f(5))/(x - 5).
First, we calculate the value of f(x) and f(5) and substitute it in the expression.
Simplifying the numerator, we get -x + 5. Finally, substituting the values, we simplify the expression to -x + 5 / (x² - 4x - 5). Therefore, the difference quotient for the given function is (-x + 5)/ (x² - 4x - 5).

solve the given differential equation. x2y'' 13xy' 36y = 0 y(x) = , x > 0
The solution to the given differential equation is y(x) = c1x^4 + c2/x^9, where c1 and c2 are arbitrary constants.
To solve the given differential equation, we can assume a solution of the form y(x) = x^r, where r is a constant to be determined. Plugging this solution into the differential equation, we get:
x^2y'' + 13xy' + 36y = 0
x^2(r(r-1)x^(r-2)) + 13x(rx^(r-1)) + 36x^r = 0
r(r-1)x^r + 13rx^r + 36x^r = 0
Factoring out x^r, we have:
x^r(r(r-1) + 13r + 36) = 0
For this equation to hold for all x > 0, the expression in the parentheses must be equal to zero. So we have:
r(r-1) + 13r + 36 = 0
r^2 + 12r + 36 = 0
(r + 6)^2 = 0
Solving for r, we find r = -6. Therefore, one solution is y1(x) = x^(-6).
Using the method of reduction of order, we can find a second linearly independent solution. We assume a second solution of the form y2(x) = v(x)y1(x), where v(x) is a function to be determined. Substituting this into the differential equation, we get:
x^2(v''(x)y1(x) + 2v'(x)y1'(x) + v(x)y1''(x)) + 13x(v'(x)y1(x) + v(x)y1'(x)) + 36v(x)y1(x) = 0
Simplifying and rearranging terms, we have:
v''(x)x^2 + 2v'(x)x^2(-6x^(-7)) + v(x)x^2(36x^(-12)) + 13v'(x)x(-6x^(-7)) + 13v(x)(-6x^(-8)) + 36v(x)x^(-6) = 0
Simplifying further, we get:
v''(x)x^2 - 12v'(x)x^(-5) + 36v(x)x^(-12) - 78v'(x)x^(-7) - 78v(x)x^(-8) + 36v(x)x^(-6) = 0
Dividing through by x^2, we obtain:
v''(x) - 12v'(x)x^(-7) + 36v(x)x^(-14) - 78v'(x)x^(-9) - 78v(x)x^(-10) + 36v(x)x^(-8) = 0
Notice that the resulting equation has terms involving positive powers of x and their derivatives. To eliminate these terms, we can make the substitution u(x) = x^6v(x). Substituting this into the equation, we get:
u''(x) - 12u'(x)x^(-1) + 36u(x)x^(-2) = 0
This is a simpler differential equation to solve, and the general solution is u(x) = c1x^4 + c2/x^9, where c1 and c2 are arbitrary constants.
Finally, substituting back u(x) = x^6v(x) and y1
