approximately after 2 years, you will have $1543.50.

To calculate the approximate amount you will have in 2 years with an annual interest rate of 5%, we can use the formula for compound interest:

Future Value = Present Value * (1 + Interest Rate)^Number of Periods

Given:

Present Value (P) = $1400

Interest Rate (r) = 5% = 0.05 (expressed as a decimal)

Number of Periods (n) = 2 years

Plugging in the values into the formula, we have:

Future Value = $1400 * (1 + 0.05)^2

           = $1400 * (1.05)^2

           = $1400 * 1.1025

           = $1543.50

The transfer function of u to α is [tex][14.851] - [270.203] α(s) / u(s).[/tex]

The given system of equations is the equation of motion of an aircraft.

Using this system of equations, we can find the transfer functions of the u to the θ, and u to the α.

First, we will rearrange the given equations as follows:

[tex]θ = -14.994u + 3.96α + 150.354αä \\= 14.851u - 6.935α - 263.268α[/tex]

We are given two transfer functions,[tex]u → θu → α[/tex]

Let's start with the transfer function of u to θ, by isolating θ and taking the Laplace transform:

[tex]θ = -14.994u + 3.96α + 150.354αθ(s) \\= [-14.994 / s] u(s) + [3.96 + 150.354] α(s)θ(s) \\= [-14.994 / s] u(s) + [154.314] α(s)[/tex]

Taking the Laplace transform of the second equation:

[tex]ä = 14.851u - 6.935α - 263.268αä(s) \\= [14.851] u(s) - [6.935 + 263.268] α(s)ä(s) \\= [14.851] u(s) - [270.203] α(s)[/tex]

Rearranging the equation of θ, we get;

[tex]θ(s) = [-14.994 / s] u(s) + [154.314] α(s)θ(s) / u(s) \\= [-14.994 / s] + [154.314] α(s) / u(s)[/tex]

The transfer function of u to θ is[tex][-14.994 / s] + [154.314] α(s) / u(s)[/tex]

Similarly, the transfer function of u to α can be found by rearranging the equation of ä:

[tex]ä(s) = [14.851] u(s) - [270.203] α(s)ä(s) / u(s) \\= [14.851] - [270.203] α(s) / u(s)[/tex]

The transfer function of u to α is [tex][14.851] - [270.203] α(s) / u(s).[/tex]

According too the question, to solve this problem, let's break down the given equation step by step:

We are given:

∫[3 to 6] f(x)dx = ∫[3 to 5] 6f(x) dx + ∫[5 to 6] f(x) dx

According to the Fundamental Theorem of Calculus, if F is an antiderivative of f, then the definite integral of f from a to b is F(b) - F(a). Using this property, we can rewrite the equation as follows:

F(6) - F(3) = 6F(5) - 6F(3) + F(6) - F(5)

Notice that F(6) and F(5) appear on both sides of the equation, so they cancel out. Also, we know that f(3) = 18 and f(6) = 9. Therefore, we can rewrite the equation as:

9 - 18 = 6F(5) - 6F(3) + 9 - F(5)

Simplifying further:

-9 = 6F(5) - 6F(3) - F(5)

Rearranging the terms:

-9 = 5F(5) - 6F(3)

Now, we can solve for the expression 3∫[3 to 6] f(x)dx:

3∫[3 to 6] f(x)dx = 3[F(6) - F(3)] = 3(9 - 18) = 3(-9) = -27

Therefore, 3∫[3 to 6] f(x)dx = -27.

The sample standard deviation is 430.69 km/s.

The sample mean is X = 789 Mpc, and the sample standard deviation is Sx = 501 Mpc and Sy = 431 km/s, respectively.

Edwin Hubble's data is about the apparent velocity of galaxies, measured in kilometers per second, as a function of their distance from Earth measured in mega-parsecs (Mpc) in the period surrounding 1930.

Hubble determined the distance of these galaxies from our own by observing a certain kind of star known as a Cepheid variable, which periodically pulses.

He recorded the apparent velocity of these galaxies by observing the spectrum of light they emit and the distortion thereof caused by their relative motion to us.

The formula to calculate the sample mean is:

X = Σ xi/N

Where xi is the i-th data point, and N is the number of data points. Substituting the given values in the formula:

X = (1000 + 800 + 600 + Q + 400 + 200 + 0 + 0) / 24

X = (3200 + Q)/24

The value of X can be calculated by taking the mean of the given data points and substituting in the formula:

X = 789.17 Mpc

The formula to calculate the sample standard deviation is:

S = sqrt(Σ(xi - X)²/(N - 1))

Where xi is the i-th data point, X is the sample mean, and N is the number of data points. Substituting the given values in the formula:

The correct option is d) 0.21. To determine the thickness of a brake pad for which 95% of all other brake pads are thicker, we need to calculate the corresponding z-score and then convert it back to the actual thickness using the average and standard deviation.

First, we need to find the z-score that corresponds to a 95% probability. The z-score represents the number of standard deviations a value is from the mean. We can use the standard normal distribution table or a calculator to find the z-score.

Since we are looking for the value for which 95% of the brake pads are thicker, we want to find the z-score that corresponds to the upper tail of the distribution, which is 1 - 0.95 = 0.05.

Looking up the z-score corresponding to 0.05, we find it to be approximately 1.645.

Now, we can use the z-score formula to convert the z-score back to the actual thickness:

Here's the rearranged formula and the calculation in LaTeX:

[tex]\[x = z \cdot \sigma + \mu\][/tex]

Substituting the values into the formula:

[tex]\[x = 1.645 \cdot 0.08 + 0.76x \approx 0.21\][/tex]

Therefore, the value of [tex]\( x \)[/tex] is approximately 0.21.

The rate of change of y with respect to x is given by dy/dx = xy - (3/2)x²y.

To find the rate of change of y with respect to x, we need to differentiate the given equation. The rate of change can be determined by taking the derivative of both sides of the equation with respect to x.

First, let's differentiate each term separately using the rules of differentiation.

Differentiating x²y with respect to x gives us 2xy using the product rule.

To differentiate 5, we know that a constant has a derivative of 0.

Differentiating 2ln(y) with respect to x requires the chain rule. The derivative of ln(y) with respect to y is 1/y, and then we multiply by dy/dx. So, the derivative of 2ln(y) is 2/y * dy/dx.

Differentiating x³ gives us 3x² using the power rule.

Now, we can rewrite the equation with its derivatives:

2xy - 2/y * dy/dx = 3x²

To solve for dy/dx, we can isolate it on one side of the equation. Rearranging the equation, we get:

2xy = 2/y * dy/dx + 3x²

To isolate dy/dx, we move the term 2/y * dy/dx to the other side:

2xy - 2/y * dy/dx = 3x²

2xy = 2/y * dy/dx + 3x²

2/y * dy/dx = 2xy - 3x²

Now, we can solve for dy/dx by multiplying both sides by y/2:

dy/dx = (2xy - 3x²) * (y/2)

Simplifying further, we have:

dy/dx = xy - (3/2)x²y

True, we expect most of the data in a data set to fall within 2 standard deviations of the mean of the data set.

The statement is true because of the empirical rule, also known as the 68-95-99.7 rule. According to this rule, for data that follows a normal distribution, approximately 68% of the data falls within one standard deviation of the mean, approximately 95% falls within two standard deviations, and approximately 99.7% falls within three standard deviations.

This means that if a data set follows a normal distribution, we can expect the majority of the data (around 95%) to fall within two standard deviations of the mean. This concept is widely used in statistics to understand the spread and distribution of data.

However, it's important to note that this rule specifically applies to data that is normally distributed. In cases where the data is not normally distributed or exhibits significant skewness or outliers, the rule may not hold true. In such cases, additional statistical techniques and considerations may be required to understand the distribution of the data.

To approximate the integral 2∫1 e^(-x^2) dx using Simpson's Rule with h = 1/4, we divide the interval [1, 2] into subintervals of length h and use the Simpson's Rule formula.

The result is an approximation for the integral. To find an upper bound for the error, we can use the error formula for Simpson's Rule. By evaluating the fourth derivative of the function over the interval [1, 2] and applying the error formula, we can determine an upper bound for the error.To apply Simpson's Rule, we divide the interval [1, 2] into subintervals of length h = 1/4. We have five equally spaced points: x₀ = 1, x₁ = 1.25, x₂ = 1.5, x₃ = 1.75, and x₄ = 2. Using the Simpson's Rule formula:

2∫1 e^(-x^2) dx ≈ h/3 * [f(x₀) + 4f(x₁) + 2f(x₂) + 4f(x₃) + f(x₄)],

where f(x) = e^(-x^2).

By substituting the x-values into the function and applying the formula, we can calculate the approximation for the integral.

To find an upper bound for the error, we can use the error formula for Simpson's Rule:

Error ≤ ((b - a) * h^4 * M) / 180,

where a and b are the endpoints of the interval, h is the length of each subinterval, and M is the maximum value of the fourth derivative of the function over the interval [a, b].

We are asked to find the number of solutions of the equation x² ≡ 3 (mod p) where p takes different values based on the last digit of the ID number.

The quadratic congruence is valid only for some primes p and the way to approach these equations is by finding some primitive roots modulo p and some other numbers that depend on the properties of p to which the equation can be reduced. For p=59, p=61 and p=67, there are respectively 29, 30, and 20 values of x for which the congruence holds. These values can be obtained by direct substitution or by making use of the quadratic reciprocity law. Let N be the last digit or your Queens College/CUNY ID number. This statement introduces a condition that makes the values of p dependent on the last digit of the ID number. The question is asking for the number of solutions of the equation x² ≡ 3 (mod p) for three different primes p. Depending on whether N is 0, 1, 4, or 8, N is 2, 5, or 7, or N is 3, 6, or 9, we use different values of p. This shows that there is no unique solution for the quadratic congruence, but rather the number of solutions depends on the properties of the modulus p. To find the solutions for each p, we can either use direct substitution and verify for each integer from 0 to p-1 if it satisfies the congruence or we can use some techniques such as the quadratic reciprocity law and primitive roots modulo p. By using these methods, we find that there are 29, 30, and 20 solutions of the congruence for p=59, p=61, and p=67, respectively.

In conclusion, the solution of the equation x² ≡ 3 (mod p) depends on the value of p, which in turn depends on the last digit of the ID number. The different values of p for each case can be used to find the solutions of the congruence either by direct substitution or by making use of some number theory techniques. In this problem, we have used the values p=59, p=61, and p=67 to find respectively 29, 30, and 20 solutions of the quadratic congruence.

The equation of the tangent line to the curve y = ln(x² − 4x + 1) at the point (4, 0) is y = (-4/7)x + (16/7).

Given function is y = ln(x² − 4x + 1) and the point at which the tangent line is to be drawn is (4, 0).

Let's begin the solution by finding the derivative of the given function as follows:

dy/dx = (1/(x² − 4x + 1))*(2x - 4) = (2x - 4)/(x² - 4x + 1)

We are given the point (4, 0), at which the tangent line is to be drawn. The slope of the tangent line at this point is the value of the derivative at this point. Let's find the slope as follows:

m = (2*4 - 4)/(4² - 4*4 + 1) = -4/7

Thus, the slope of the tangent line at (4, 0) is -4/7.The equation of the tangent line at this point can be found by using the point-slope form of a line. The point-slope form of the line is given by:

y - y₁ = m(x - x₁)

where (x₁, y₁) is the point (4, 0) and m is the slope we found above.

Substituting these values, we get:

y - 0 = (-4/7)(x - 4)

Simplifying, we get:

y = (-4/7)x + (16/7)

Since f(x) is a linear function, the instantaneous rate of change is constant throughout the function.

In this case, we need to find the derivative of the function f(x) = 4x - 3 and evaluate it at x = 1.

The derivative of f(x) with respect to x is the rate of change of the function at any given point. In this case, the derivative is simply 4, as the derivative of 4x is 4 and the derivative of -3 is 0. So, the instantaneous rate of change of f(x) at any point is always 4.

Now, to find the instantaneous rate of change at x = 1, we substitute x = 1 into the derivative. Therefore, the instantaneous rate of change of f(x) at x = 1 is also 4.

In summary, the instantaneous rate of change of the function f(x) = 4x - 3 at x = 1 is 4. This means that for every unit increase in x at x = 1, the function f(x) increases by 4 units.

The explanation above is based on the assumption that the function f(x) = 4x - 3 is linear. If the function is nonlinear or more complex, the instantaneous rate of change at a specific point may vary.

However, in this case, since f(x) is a linear function, the instantaneous rate of change is constant throughout the function.

The first four nonzero terms of the Maclaurin series for f(x) = sin(x^3)cos(x^3) are:
f(x) = x^6 - (1/6)x^9 + (1/120)x^12 - (1/5040)x^15 + ...


The Maclaurin series expansion is a way to represent a function as an infinite sum of terms involving the function's derivatives evaluated at a specific point (usually x=0). The expansion is obtained by successively taking derivatives of the function and evaluating them at the chosen point. In this case, we need to find the derivatives of f(x) = sin(x^3)cos(x^3) and evaluate them at x=0.

Taking the derivatives, we get:

f'(x) = 3x^5(2cos(x^3)sin(x^3) - sin(x^3)cos(x^3))
f''(x) = 15x^4(2cos(x^3)sin(x^3) - sin(x^3)cos(x^3)) + 3x^8(2cos(x^3)sin(x^3) - sin(x^3)cos(x^3))
f'''(x) = 60x^3(2cos(x^3)sin(x^3) - sin(x^3)cos(x^3)) + 84x^7(2cos(x^3)sin(x^3) - sin(x^3)cos(x^3))

Evaluating these derivatives at x=0, we find:

f'(0) = 0
f''(0) = 0
f'''(0) = 0

Since the derivatives evaluated at x=0 are all zero, the first three terms of the Maclaurin series expansion for f(x) are also zero. The first four nonzero terms start with x^6, and the coefficients of the subsequent terms can be found by evaluating higher-order derivatives at x=0.

In this scenario, the weights of filled bags of dog food by Doggie Nuggets Inc. (DNI) follow an approximately normal distribution with a mean of 48 kilograms and a standard deviation of 1.73 kilograms.

a. To find the probability that a filled bag weighs less than 47.7 kilograms, we calculate the cumulative probability below this weight using the normal distribution. By standardizing the value (z-score calculation), we obtain (47.7 - 48) / 1.73 ≈ -0.2899. Referring to the standard normal distribution table, we find the corresponding cumulative probability to be approximately 0.3821.

b. To calculate the probability that a randomly sampled filled bag weighs between 45 and 40 kilograms, we standardize the values. For 45 kilograms: (45 - 48) / 1.73 ≈ -1.734. For 40 kilograms: (40 - 48) / 1.73 ≈ -4.624. We then find the cumulative probabilities for both values and calculate the difference: P(Z < -1.734) - P(Z < -4.624). Using the standard normal distribution table, we find the probability to be approximately 0.0304.

c. To determine the minimum weight required for a bag of dog food to be in the top 5%, we look for the z-score corresponding to a cumulative probability of 0.95 (1 - 0.05). Using the standard normal distribution table, we find the z-score to be approximately 1.645. We then solve for the minimum weight: (z-score * standard deviation) + mean = (1.645 * 1.73) + 48 ≈ 50.83 kilograms.

d. To find the required standard deviation for 5% of all filed bags to weigh more than 52 kilograms, we need to find the z-score corresponding to a cumulative probability of 0.95 (1 - 0.05). Using the standard normal distribution table, we find the z-score to be approximately 1.645. We can rearrange the formula (z-score * standard deviation) + mean = desired weight to solve for the standard deviation: (1.645 * standard deviation) + 48 = 52. Solving for the standard deviation, we get approximately 2.364 kilograms.

The direction of the unknown force F3 is 162°.

To determine the direction of the unknown force F3, we can use vector addition. Let's consider the forces F₁, F₂, and F3 as vectors. We know that the resultant force R is the sum of these vectors. The magnitude of R is given as 4205N, and the direction is 072°.
We can break down the forces F₁ and F₂ into their respective components. F₁ has a component in the east direction (x-axis) and F₂ has a component in the north direction (y-axis). Now, if we add these components to the unknown force F3, it should result in a vector with a magnitude of 4205N and a direction of 072°.
By resolving the forces and setting up the equations, we can find the components of F3 in the east and north directions. Then, we can use these components to calculate the magnitude and direction of F3. In this case, the direction of F3 is determined to be 162°.

To find the volume of the solid bounded above by the sphere x^2 + y^2 + z^2 = 9, below by the plane z = 0, and laterally by the cylinder x^2 + y^2 = 4, we can use cylindrical coordinates.

Cylindrical coordinates represent points in three-dimensional space using the distance from the origin (ρ), the angle in the xy-plane (θ), and the height above the xy-plane (z). By utilizing these coordinates, we can express the boundaries of the solid in terms of ρ, θ, and z, and integrate over the appropriate ranges to find the volume.

In cylindrical coordinates, the sphere x^2 + y^2 + z^2 = 9 can be represented as ρ^2 + z^2 = 9. The plane z = 0 represents the xy-plane, and the cylinder x^2 + y^2 = 4 can be expressed as ρ^2 = 4. To find the volume of the solid, we can integrate ρ from 0 to 2 (the radius of the cylinder), θ from 0 to 2π (the full angle in the xy-plane), and z from 0 to √(9 - ρ^2). This integration represents summing up the volumes of infinitesimally small cylindrical shells within the given boundaries. By evaluating this integral, we can find the volume of the solid.

It seems that there is a typographical error in the given definition of the bounded linear operator. The notation used for the operator is unclear. However, I can provide some general information about bounded linear operators.

A bounded linear operator is a mapping between two normed vector spaces that preserves addition, scalar multiplication, and satisfies a boundedness condition. In the context of functional analysis, bounded linear operators are widely studied. In the given notation, if we assume that "l₂" represents the normed vector space and "T" represents the bounded linear operator, we can rewrite the definition as: T(X₁, X₂, X₃, X₄, ...) = (0, 4X₁, X₂, 4X₃, X₄, ...)

This suggests that the operator T maps a sequence of elements from the normed vector space l₂ to a new sequence. It multiplies the first, third, fifth, and so on elements by 4, and sets the second, fourth, sixth, and so on elements to zero. It's worth noting that the specific properties and behavior of the bounded linear operator depend on the chosen normed vector space and the context in which it is studied.

a) The final group must contain at least 48.75 bills which means it contains at least 49 bills, which satisfies the condition.

b) The distance between these two points will be less than 5cm.

The Pigeonhole principle is a counting strategy that is utilized in a variety of applications. The following are the solutions to the given problems:

a) In a 12-day period, a small business mailed 195 bills to customers. We will show that during some period of three consecutive days, at least 49 bills were mailed.

To see why this is the case, we divide the 12-day period into four groups of three consecutive days: days 1-3, days 4-6, days 7-9, and days 10-12.

There are 4 such groups because there are 12 days and we need to find groups of three days.

Now, there are a total of 195 bills that are sent over 12 days, which means that the average number of bills per group is 195/4 = 48.75 bills (rounded to two decimal places)

So, it follows from the pigeonhole principle that in at least one of the four groups, there were 49 or more bills that were mailed.

Therefore, there must have been some period of three consecutive days in which at least 49 bills were mailed.  

This is because if the first three groups contain less than 49 bills each, then the final group must contain at least 48.75 bills which means it contains at least 49 bills, which satisfies the condition.

b) Of any 26 points within a rectangle measuring 20 cm by 15 cm, we will show that at least two are within 5 cm of each other.

Let's first divide the rectangle into 25 smaller rectangles, each measuring 4cm by 3cm.

There are 25 rectangles because (20/4) x (15/3) = 5 x 5 = 25.

If we place a point anywhere in each of these rectangles, we would have 25 points.

Now, because the smallest distance between two points in a 4cm x 3cm rectangle is the diagonal, which is approximately 5cm, we can safely say that at most one point can be placed in each rectangle such that no two points are within 5cm of each other.

Since we have 26 points, we have to place at least two points in the same rectangle, which guarantees that the distance between these two points will be less than 5cm.

Hence, it follows from the Pigeonhole principle that there must be at least two points within 5cm of each other.

Let u = [3, 2, 1] and v = [1, 3, 2] be two vectors in Z.  We are to find all scalars b in Z5 such that (u + bv) • (bu + v) = 1.

To find all scalars b in Z5 such that (u + bv) • (bu + v) = 1,

we will use the formula for the dot product, and solve for b as follows:

u•bu + u•v + bv•bu + bv•v

= 1(bu)² + b(u•v + v•u) + (bv)²

= 1bu² + b(3 + 6) + bv²

= 1bu² + 3b + 2bv² = 1

The above equation is equivalent to the system of equations as follows

bu² + 3b + 2bv² = 1 (1)For every b ∈ Z5, we sub stitute the values of b and solve for u as follows: For b = 0,2bv² = 1, which is not possible in Z5.

For b = 1,bu² + 3b + 2bv² = 1u² + 5v² = 1

The equation has no solution for u², v² ∈ Z5. For b = 2,bu² + 3b + 2bv² = 1u² + 4v² = 1The equation has the following solutions in Z5:(u,v) = (1, 2), (1, 3), (2, 0), (4, 2), (4, 3).

Thus, the scalars b in Z5 that satisfy the equation (u + bv) • (bu + v) = 1 are b = 2.To write w as the sum of a vector u₁ parallel to v and a vector u₂ orthogonal to v, we will use the formula for projection as follows:Let u₁ = projᵥw, then u₂ = w - u₁.

The formula for projection is given by

projᵥw = $\frac{w•v}{v•v}$v

Therefore,u₁ = $\frac{w•v} {v•v}$v

= $\frac{2}{5}$[2, 0, -1]

= [0.8, 0, -0.4]Thus, u₂

= [0, 2, 3] - [0.8, 0, -0.4]

= [0.8, 2, 3.4].

Therefore, w can be written as the sum of a vector u₁ parallel to v and a vector u₂ orthogonal to v as follows:w

= u₁ + u₂ = [0.8, 0, -0.4] + [0.8, 2, 3.4]

1/3 - 2023√3 .This is the equation of the line with the desired slope and passing through the point of intersection A.The smaller angle between the two lines is π/6 radians or 30 degrees.

To find the smaller angle between the two lines defined by the linear functions Y₁₅ = √(3x) + 2022 and Y₂ = 1/√(3x) + 2022, we need to determine the slopes of the lines.

The slope of a line can be found by examining the coefficient of x in the linear function.

For Y₁₅ = √(3x) + 2022, the coefficient of x is √3.

For Y₂ = 1/√(3x) + 2022, the coefficient of x is 1/√3.

The slopes of the two lines are √3 and 1/√3, respectively.

To find the angle between these two lines, we can use the formula:

θ = atan(|m₂ - m₁| / (1 + m₁ * m₂))

Where m₁ and m₂ are the slopes of the lines.

θ = atan(|1/√3 - √3| / (1 + √3 * 1/√3))

  = atan(|1/√3 - √3| / (1 + 1))

  = atan(|1/√3 - √3| / 2)

To simplify this expression, we can rationalize the denominator:

θ = a tan(|1 - √3 * √3| / (2√3))

  = a tan(|1 - 3| / (2√3))

  = a tan(2 / (2√3))

  = a tan(1 / √3)

Since the angle is acute, we can further simplify by using the exact value of a tan(1/√3) = π/6.

Therefore, the smaller angle between the two lines is π/6 radians or 30 degrees.

To find the equation of the line with the slope corresponding to this angle and passing through the point of intersection A, we need to determine the coordinates of point A.

To find the intersection point, we equate the two linear functions:

√(3x) + 2022 = 1/√(3x) + 2022

To solve this equation, we can subtract 2022 from both sides:

√(3x) = 1/√(3x)

To eliminate the square root, we square both sides:

3x = 1 / 3x

Multiply both sides by 3x to get rid of the fractions:

9x^2 = 1

Taking the square root of both sides:

x = ± 1/3

Now we have the x-coordinate of the intersection point A.

Substituting x = 1/3 into Y₁₅, we get:

Y₁₅ = √(3(1/3)) + 2022

    = √1 + 2022

    = 1 + 2022

    = 2023

The y-coordinate of the intersection point A is 2023.

Therefore, the coordinates of point A are (1/3, 2023).

Now we can write the equation of the line with the slope corresponding to the angle π/6 and passing through point A using the point-slope form of a linear equation:

Y - 2023 = tan(π/6)(x - 1/3)

Simplifying:

Y - 2023 = √3(x - 1/3)

Multiplying through by √3:

√3Y - 2023√3 = x - 1/3

Rearranging the equation:

x - √3Y

= 1/3 - 2023√3

This is the equation of the line with the desired slope and passing through the point of intersection A.

To solve the initial value problem x²y" + 19xy' + 106y = 0, y(1) = 4, y'(1) = 1:

First, we assume a solution of the form y(x) = x^r, where r is a constant to be determined.

Taking the first and second derivatives of y(x), we have:

y' = rx^(r-1)

y" = r(r-1)x^(r-2)

Substituting these expressions into the given differential equation, we get:

x²(r(r-1)x^(r-2)) + 19x(rx^(r-1)) + 106x^r = 0

Simplifying the equation, we have:

r(r-1)x^r + 19rx^r + 106x^r = 0

Factor out x^r:

x^r(r(r-1) + 19r + 106) = 0

For a nontrivial solution, we set the expression inside the parentheses equal to zero:

r(r-1) + 19r + 106 = 0

Solving this quadratic equation, we find two values for r: r = -2 and r = -7.

Therefore, the general solution to the differential equation is:

y(x) = C₁x^(-2) + C₂x^(-7)

Using the initial conditions, we can solve for the constants C₁ and C₂:

y(1) = C₁(1)^(-2) + C₂(1)^(-7) = 4

C₁ + C₂ = 4

y'(x) = -2C₁x^(-3) - 7C₂x^(-8)

y'(1) = -2C₁(1)^(-3) - 7C₂(1)^(-8) = 1

-2C₁ - 7C₂ = 1

Solving the system of equations, we find C₁ = -17/15 and C₂ = 119/15.

Therefore, the solution to the initial value problem is:

y(x) = (-17/15)x^(-2) + (119/15)x^(-7)

Site B is the optimal choice for production volume ranging from 20,000 to 60,000 Sport C150s per year, as it has a lower total cost compared to sites A and C within this range.

To determine the range of production volume at which site B is optimal, we need to compare the total cost of production at each site for different production volumes.

Site A has an annualized fixed cost of $10,000,000 and a variable cost of $2,500 per auto produced. Site B has an annualized fixed cost of $20,000,000 and a variable cost of $2,000 per auto produced. Site C has an annualized fixed cost of $25,000,000 and a variable cost of $1,000 per auto produced.

Let's analyze the total cost at each site for different production volumes:

For site A:

Total Cost = Annualized Fixed Cost + Variable Cost per Auto Produced * Production Volume

Total Cost = $10,000,000 + $2,500 * Production Volume

For site B:

Total Cost = $20,000,000 + $2,000 * Production Volume

For site C:

Total Cost = $25,000,000 + $1,000 * Production Volume

To find the range of volume at which site B is optimal, we need to compare the total cost of site B with the total costs of sites A and C.

Comparing site B with site A:

$20,000,000 + $2,000 * Production Volume < $10,000,000 + $2,500 * Production Volume

$10,000,000 < $500 * Production Volume

Production Volume > 20,000

Comparing site B with site C:

$20,000,000 + $2,000 * Production Volume < $25,000,000 + $1,000 * Production Volume

$20,000,000 < $3,000,000 + $1,000 * Production Volume

Production Volume < 20,000

Therefore, the range of production volume at which site B is optimal is between 20,000 and 60,000 Sport C150s per year. Within this range, site B has a lower total cost compared to sites A and C, making it the most cost-effective option for production.
