To calculate f'(-1), we need to find the derivative of the function f(x) with respect to x and evaluate it at x = -1.  Given that f(x) = (h(x))^6, we can apply the chain rule to find the derivative of f(x).

The chain rule states that if we have a composition of functions, the derivative is the product of the derivative of the outer function and the derivative of the inner function. Let's denote g(x) = h(x)^6. Applying the chain rule, we have:

f'(x) = 6g'(x)h(x)^5.

To find f'(-1), we need to evaluate this expression at x = -1. We are given that h(-1) = 5, and h'(-1) = 8.

Substituting these values into the expression for f'(x), we have:

f'(-1) = 6g'(-1)h(-1)^5.

Since g(x) = h(x)^6, we can rewrite this as:

f'(-1) = 6(6h(-1)^5)h(-1)^5.

Simplifying, we have:

f'(-1) = 36h'(-1)h(-1)^5.

Substituting the given values, we get:

f'(-1) = 36(8)(5)^5 = 36(8)(3125) = 900,000.

Therefore, f'(-1) = 900,000.

The solution to the differential equation dp dt = 7 pt, p(1) = 5 with the initial condition is p = 5e^(3.5t^2 - 3.5).

To solve the differential equation dp/dt = 7pt with the initial condition p(1) = 5, we can use separation of variables and integration.

Let's separate the variables by writing the equation as dp/p = 7t dt.

Integrating both sides, we get ∫(dp/p) = ∫(7t dt).

This simplifies to ln|p| = 3.5t^2 + C, where C is the constant of integration.

To determine the value of C, we use the initial condition p(1) = 5. Plugging in t = 1 and p = 5, we have ln|5| = 3.5(1^2) + C.

Simplifying further, ln(5) = 3.5 + C.

Solving for C, we find C = ln(5) - 3.5.

Substituting this value back into the equation, we have ln|p| = 3.5t^2 + ln(5) - 3.5.

Applying the properties of logarithms, we can rewrite this as ln|p| = ln(5e^(3.5t^2 - 3.5)).

Therefore, the solution to the differential equation with the initial condition is p = 5e^(3.5t^2 - 3.5).

The puppy's weight increases by 3 pounds every 2 weeks, representing a constant growth pattern. To represent this, use the slope-intercept form of a linear equation, y = mx + b, starting at 10 pounds.

To determine the equation that represents the growth of the puppy's weight, we need to identify the pattern in the given list of weights.

From the list, we can observe that the puppy's weight increases by 3 pounds every 2 weeks. This means that the weight is increasing at a constant rate of 3 pounds every 2 weeks.

To represent this growth pattern in an equation, we can use the slope-intercept form of a linear equation, which is y = mx + b.

In this case, the weight of the puppy (y) is the dependent variable and the number of weeks (x) is the independent variable. The slope (m) represents the rate of change of the weight, which is 3 pounds every 2 weeks.

Since the puppy's weight starts at 10 pounds when Salomon brings her home, the y-intercept (b) is 10.

Therefore, the equation that represents the growth of the puppy's weight is:

y = (3/2)x + 10

This equation shows that the puppy's weight increases by 3/2 pounds every week, starting from an initial weight of 10 pounds.

The number of phases for this hybrid stepper motor must be 4.

To determine the number of phases for a hybrid stepper motor with a rotor pitch of 36º and a step angle of 9º, we need to consider the relationship between the rotor pitch and the step angle.

The rotor pitch is the angle between two consecutive rotor teeth or salient poles. In this case, the rotor pitch is 36º, meaning there are 10 rotor teeth since 360º (a full circle) divided by 36º equals 10.

The step angle, on the other hand, is the angle between two consecutive stator poles. For a hybrid stepper motor, the step angle is determined by the number of stator poles and the excitation sequence of the phases.

To find the number of phases, we divide the rotor pitch by the step angle. In this case, 36º divided by 9º equals 4.

Each phase of the stepper motor is energized sequentially to rotate the motor shaft by the step angle. By energizing the phases in a specific sequence, the motor can achieve precise positioning and rotation control.

It's worth noting that the number of phases in a hybrid stepper motor can vary depending on the specific design and application requirements. However, in this scenario, with a rotor pitch of 36º and a step angle of 9º, the number of phases is determined to be 4.

According to the Question, the absolute value function that represents the V-shaped outline of the Transamerica Pyramid's sides is:

[tex]y=|\frac{853}{72.5} x|.[/tex]

We may use an absolute value function to build the V-shaped contour of the Transamerica Pyramid's sides. Consider the coordinate plane, where the x-axis represents the horizontal direction and the y-axis represents the vertical direction.

Because the structure is symmetrical, we may concentrate on one side of the V-shaped form. To ensure symmetry, we'll create our function for the right side of the building and then take the absolute value.

Assume the origin (0,0) lies at the vertex of the V-shaped contour. The slope of the line from the vertex to a point on the outline may be used to calculate the equation of the right side of the border.

The right side of the outline is a straight line segment that extends from the vertex to the building's highest point (the peak of the V-shape). The uppermost point's x-coordinate is half the breadth of the base or 145/2 = 72.5 feet. The y-coordinate of the highest point is the building's height, which is 853 feet.

Using the slope formula, we can calculate the slope of the line:

[tex]m=\frac{y_2-y_1}{x_2-x_1} \\\\m=\frac{853-0}{72.5-0} \\\\m=\frac{853}{72.5}[/tex]

The equation of the right side of the outline can be written as:

[tex]y=\frac{853}{72.5} x[/tex]

We must take the absolute value of this equation to account for the left side to produce the V-shaped contour. The total value function ensures that the shape is symmetric concerning the y-axis.

Therefore, the absolute value function that represents the V-shaped outline of the Transamerica Pyramid's sides is:

The measure of ∠4, given that angles 3 and 4 are complementary and ∠3 = 27 degrees, is 63 degrees. Complementary angles add up to 90 degrees, so by subtracting the given angle from 90, we find that ∠4 is 63 degrees.

Complementary angles are two angles that add up to 90 degrees. Since ∠3 and ∠4 are complementary, we can set up the equation ∠3 + ∠4 = 90. Substituting the given value of ∠3 as 27, we have 27 + ∠4 = 90. To solve for ∠4, we subtract 27 from both sides of the equation: ∠4 = 90 - 27 = 63.

Therefore, the measure of ∠4 is 63 degrees.

a) The volume of region R rotated about the y-axis is (2π/3) cubic units.

b) The volume of region R rotated about the vertical line x=5 is (32π/15) cubic units.

c) The volume of region R rotated about the horizontal line y=4 is (8π/3) cubic units.

d) The volume of the shape with R as its base, where cross-sections perpendicular to the x-axis are squares, is (16/15) cubic units.

To find the volume of the region R rotated about different axes, we need to use the method of cylindrical shells. Let's analyze each case individually:

a) Rotating about the y-axis:

The region R is bounded by the curves y = [tex](x - 3)^2[/tex] and y = x - 1. By setting the two equations equal to each other, we can find the points of intersection: (2, 1) and (4, 1). Integrating the expression (2πx)(x - 1 - (x - 3)^2) from x = 2 to x = 4 will give us the volume of the solid. Solving the integral yields a volume of (2π/3) cubic units.

b) Rotating about the vertical line x = 5:

To rotate the region R about the line x = 5, we need to adjust the limits of integration. By substituting x = 5 - y into the equations of the curves, we can find the new equations in terms of y. The points of intersection are now (4, 1) and (6, 3). The integral to evaluate becomes (2πy)(5 - y - 1 - [tex](5 - y - 3)^2)[/tex], integrated from y = 1 to y = 3. After solving the integral, the volume is (32π/15) cubic units.

c) Rotating about the horizontal line y = 4:

Similar to the previous case, we substitute y = 4 + x into the equations to find the new equations in terms of x. The points of intersection become (2, 4) and (4, 2). The integral to evaluate is (2πx)((4 + x) - 1 - [tex]((4 + x) - 3)^2)[/tex], integrated from x = 2 to x = 4. Solving this integral results in a volume of (8π/3) cubic units.

d) Cross-sections perpendicular to the x-axis are squares:

When the cross-sections perpendicular to the x-axis are squares, the height of each square is given by the difference between the curves y =  [tex](x - 3)^2[/tex] and y = x - 1. This difference is [tex](x - 3)^2[/tex] - (x - 1) = [tex]x^2[/tex] - 5x + 4. Integrating the expression (x^2 - 5x + 4) dx from x = 2 to x = 4 will provide the volume of the shape.

There are no values of t on the interval [0,3] where the value of the derivative is equal to the average rate of change for the function [tex]v(t)=4t^2-6t+2.[/tex]

The derivative of the function v(t) can be found by taking the derivative of each term separately. Applying the power rule, we get v'(t) = 8t - 6. To determine the average rate of change, we need to calculate the difference in the function's values at the endpoints of the interval and divide it by the difference in the corresponding values of t.

In this case, the average rate of change is (v(3) - v(0))/(3 - 0). Simplifying this expression gives (35 - 2)/3 = 33/3 = 11.

Now, we set the derivative v'(t) equal to the average rate of change, which gives us the equation 8t - 6 = 11. Solving this equation, we find t = 17/8. Since the interval is [0,3], we need to check if the obtained value of t falls within this interval.

In this case, t = 17/8 is greater than 3, so it does not satisfy the conditions. Therefore, there are no values of t on the closed interval [0,3] where the value of the derivative is equal to the average rate of change for the given function.

The estimated probability that a random test score is between 46 and 86 is approximately 0.9906, rounded to four decimal places.

We can use the Maclaurin series expansion for the standard normal distribution, which is given by e^(-z^2/2). We will approximate this series using the first five terms.

First, we convert the given test scores to z-scores using the formula z = (x - μ) / σ, where x is the test score, μ is the mean, and σ is the standard deviation.

For 46, the z-score is z = (46 - 66) / 10 = -2.

For 86, the z-score is z = (86 - 66) / 10 = 2.

Next, we can use the Maclaurin series for e^(-z^2/2) up to the fifth term, which is:

e^(-z^2/2) ≈ 1 - z + (z^2)/2 - (z^3)/6 + (z^4)/24.

Substituting the z-scores into the series, we have:

e^(-(-2)^2/2) ≈ 1 - (-2) + ((-2)^2)/2 - ((-2)^3)/6 + ((-2)^4)/24 ≈ 0.9953.

e^(-(2)^2/2) ≈ 1 - (2) + (2^2)/2 - (2^3)/6 + (2^4)/24 ≈ 0.0047.

The probability between 46 and 86 is the difference between these two approximations:

P(46 < x < 86) ≈ 0.9953 - 0.0047 ≈ 0.9906.

Therefore, the estimated probability that a random test score is between 46 and 86 is approximately 0.9906, rounded to four decimal places.

The transition matrix A is [tex]\left[\begin{array}{ccc}0&13&-2/3\\0&2&1\\0&0&1/2\end{array}\right][/tex] .

To find the transition matrix from vector b to vector b', we can set up a linear system of equations and solve for the coefficients of the matrix.

Let's denote the transition matrix as A. We want to find A such that b' = A * b.

b = (4, 1, -6), (3, 1, -6), (9, 3, -16)

b' = (5, 8, 6), (2, 4, 3), (2, 4, 4)

Let's write the equation for the first row:

(5, 8, 6) = A * (4, 1, -6)

This can be expanded into three equations:

5 = 4[tex]a_{11[/tex] + 1[tex]a_{21[/tex] - 6[tex]a_{31[/tex]

8 = 4[tex]a_{12[/tex] + 1[tex]a_{22[/tex] - 6[tex]a_{32[/tex]

6 = 4[tex]a_{13[/tex] + 1[tex]a_{23[/tex] - 6[tex]a_{33[/tex]

Similarly, we can write equations for the second and third rows:

(2, 4, 3) = A * (3, 1, -6)

(2, 4, 4) = A * (9, 3, -16)

Expanding these equations, we have:

2 = 3[tex]a_{11[/tex] + 1[tex]a_{21[/tex] - 6[tex]a_{31[/tex]

4 = 3[tex]a_{12[/tex] + 1[tex]a_{22[/tex] - 6[tex]a_{32[/tex]

3 = 3[tex]a_{13[/tex] + 1[tex]a_{23[/tex] - 6[tex]a_{33[/tex]

2 = 9[tex]a_{11[/tex] + 3[tex]a_{21[/tex] - 16[tex]a_{31[/tex]

4 = 9[tex]a_{12[/tex] + 3[tex]a_{22[/tex] - 16[tex]a_{32[/tex]

4 = 9[tex]a_{13[/tex] + 3[tex]a_{23[/tex] - 16[tex]a_{33[/tex]

Now, we have a system of linear equations. We can solve this system to find the coefficients of matrix A.

The augmented matrix for this system is:

[4 1 -6 | 5]

[3 1 -6 | 8]

[9 3 -16 | 6]

[3 1 -6 | 2]

[9 3 -16 | 4]

[9 3 -16 | 4]

We can perform row operations to reduce the matrix to row-echelon form. I'll perform these row operations:

[[tex]R_2[/tex] - (3/4)[tex]R_1[/tex] => [tex]R_2[/tex]]

[[tex]R_3[/tex] - (9/4)[tex]R_1[/tex] => [tex]R_3[/tex]]

[[tex]R_4[/tex] - (1/3)[tex]R_1[/tex] => [tex]R_4[/tex]]

[[tex]R_5[/tex] - (3/9)[tex]R_1[/tex] => [tex]R_5[/tex]]

[[tex]R_6[/tex] - (9/9)[tex]R_1[/tex] => [tex]R_6[/tex]]

The new augmented matrix is:

[4 1 -6 | 5]

[0 1 0 | 2]

[0 0 0 | -3]

[0 0 0 | -2]

[0 0 0 | -2]

[0 0 0 | 1]

Now, we can back-substitute to solve for the variables:

From row 6, we have -2[tex]a_{33[/tex] = 1, so [tex]a_{33[/tex] = -1/2

From row 5, we have -2[tex]a_{32[/tex] = -2, so [tex]a_{32[/tex] = 1

From row 4, we have -3[tex]a_{31[/tex] = -2, so [tex]a_{31[/tex] = 2/3

From row 2, we have [tex]a_{22[/tex] = 2

From row 1, we have 4[tex]a_{11[/tex] + [tex]a_{21[/tex] - 6[tex]a_{31[/tex] = 5. Plugging in the values we found so far, we get 4[tex]a_{11[/tex]+ [tex]a_{21[/tex] - 6(2/3) = 5. Simplifying, we have 4[tex]a_{11[/tex] + [tex]a_{21[/tex] = 13. Since we have one equation and two variables, we can choose [tex]a_{11[/tex] and [tex]a_{21[/tex] freely. Let's set [tex]a_{11[/tex] = 0 and [tex]a_{21[/tex] = 13.

The Cauchy-Riemann equations state that the partial derivatives of the function's real and imaginary parts must exist and satisfy certain relationships.

Let's consider the function f(z) = 1/z, where z = x + yi, with x and y being real numbers. We can express f(z) as f(z) = u(x, y) + iv(x, y), where u(x, y) represents the real part and v(x, y) represents the imaginary part of the function.

In this case, u(x, y) = 1/x and v(x, y) = 0. Taking the partial derivatives of u and v with respect to x and y, we have ∂u/∂x = -1/x^2, ∂u/∂y = 0, ∂v/∂x = 0, and ∂v/∂y = 0.

The Cauchy-Riemann equations require that ∂u/∂x = ∂v/∂y and ∂u/∂y = -∂v/∂x. However, in this case, these conditions are not satisfied since ∂u/∂x ≠ ∂v/∂y and ∂u/∂y ≠ -∂v/∂x. Therefore, the function f(z) = 1/z does not satisfy the Cauchy-Riemann equations and is not analytic for all values of z.

If the city is planting each tree 12 feet apart, then they can plant 880 trees on 2 miles of streets.

To determine how many trees can be planted on 2 miles of streets, we need to convert the distance from miles to feet. Since there are 5,280 feet in a mile, 2 miles of streets would be equal to:

2 * 5,280 = 10,560 feet.

Given that each tree is being planted 12 feet apart, we can divide the total length of the streets by the distance between each tree to find the number of trees that can be planted.

So, 10,560 feet divided by 12 feet per tree equals 880 trees. Therefore, they can plant 880 trees on 2 miles of streets.

The absolute maximum of the function \(f(x) = 2x^3 - 33x^2 + 144x\) on the interval \([2, 9]\) is 297.

a. The absolute maximum of \(f\) on the given interval is at \(x = 9\).

b. Graphing utility can be used to confirm this conclusion by plotting the function \(f(x)\) over the interval \([2, 9]\) and observing the highest point on the graph.

To determine the absolute extreme values of the function \(f(x) = 2x^3 - 33x^2 + 144x\) on the interval \([2, 9]\), we can follow these steps:

1. Find the critical points of the function within the given interval by finding where the derivative equals zero or is undefined.

2. Evaluate the function at the critical points and the endpoints of the interval.

3. Identify the highest and lowest values among the critical points and the endpoints to determine the absolute maximum and minimum.

Let's begin with step 1 by finding the derivative of \(f(x)\):

\(f'(x) = 6x^2 - 66x + 144\)

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

\(6x^2 - 66x + 144 = 0\)

Simplifying the equation by dividing through by 6:

\(x^2 - 11x + 24 = 0\)

Factoring the quadratic equation:

\((x - 3)(x - 8) = 0\)

So, we have two critical points at \(x = 3\) and \(x = 8\).

Now, let's move to step 2 and evaluate the function at the critical points and the endpoints of the interval \([2, 9]\):

For \(x = 2\):

\(f(2) = 2(2)^3 - 33(2)^2 + 144(2) = 160\)

For \(x = 3\):

\(f(3) = 2(3)^3 - 33(3)^2 + 144(3) = 171\)

For \(x = 8\):

\(f(8) = 2(8)^3 - 33(8)^2 + 144(8) = 80\)

For \(x = 9\):

\(f(9) = 2(9)^3 - 33(9)^2 + 144(9) = 297\)

Now, we compare the values obtained in step 2 to determine the absolute maximum and minimum.

The highest value is 297, which occurs at \(x = 9\), and there are no lower values in the given interval.

Therefore, the absolute maximum of the function \(f(x) = 2x^3 - 33x^2 + 144x\) on the interval \([2, 9]\) is 297.

The set W, which consists of all vectors in R^2 with integer components, is not a subspace of R^2. This is because it fails to satisfy the conditions of closure under addition and scalar multiplication.

To be a subspace, W must meet three criteria. The first criterion is that it contains the zero vector, which is (0, 0) in R^2. Since the zero vector has integer components, W satisfies this criterion.

However, W fails to meet the other two criteria. Closure under addition requires that if u and v are vectors in W, their sum u + v must also be in W. But if we take two vectors with non-integer components, such as (1.5, 2) and (3, -1.5), their sum would have non-integer components, violating closure under addition.

Similarly, closure under scalar multiplication demands that if u is a vector in W and c is any scalar, the scalar multiple c*u must also be in W. However, multiplying a vector with integer components by a non-integer scalar would result in components that are not integers, thus breaking the closure under scalar multiplication.

Therefore, since W fails to satisfy both closure under addition and closure under scalar multiplication, it is not a subspace of R^2.

The first five terms of the sequence using the recursion formula are:

(2, -1, -1/2, 1/2, 1/2).

The given sequence starts with a₁ = 2.

To find the next term a₂, we use the recursion formula aₙ₊₁ = (-1)ⁿ⁺¹ .aₙ/2. Plugging in the values, we have a₂ = (-1)⁽²⁺¹⁾ .1/2. Here, (n+1) becomes 2+1 = 3, and aₙ becomes a₁, which is 2.

Now, let's evaluate the expression. (-1)⁽²⁺¹⁾ is (-1)³, which equals -1. Multiplying -1 by 1/2, which is 2/2, gives us -1. 1= -1.

Therefore, the second term, a₂, is -1.

To find the next term, a₃, we once again use the recursion formula. Substituting the values, we have a₃ = (-1)⁽³⁺¹⁾ .a₂/2. Here, (n+1) becomes 3+1 = 4, and aₙ becomes a₂, which is -1.

Evaluating the expression, (-1)⁽³⁺¹⁾becomes (-1)⁴, which equals 1. Multiplying 1 by a₂/2, which is -1/2, gives us 1. -1/2 = -1/2.

Hence, the third term, a₃, is -1/2.

We can continue this process to find the remaining terms:

a₄ = (-1)⁽⁴⁺¹⁾ .3/2 = (-1)⁵ . -1/2 = 1 . -1/2 = 1/2

a₅= (-1)⁽⁵⁺¹⁾. 4/2 = (-1)⁶. 1/2 = 1 .1/2 = 1/2

Therefore, the first five terms of the sequence are:

(2, -1, -1/2, 1/2, 1/2).

There are 32 possible outcomes in the sample space when five coins are tossed simultaneously.

When five coins are tossed simultaneously, each coin has two possible outcomes: heads or tails.

Since there are five coins, the total number of possible outcomes for each coin is 2.

To find the number of elements in the sample space, we need to multiply these possibilities together.

Using the multiplication principle, the total number of elements in the sample space is calculated by raising 2 to the power of 5 (since there are 5 coins).

So, the number of elements in the sample space is 2⁵, which equals 32.

The equation of the tangent line at x=0 is y=e.

To find the equation of the tangent line at x=0, we need to determine the slope of the tangent line and a point on the line.

Differentiate the given equation.

Differentiating both sides of the equation xy + ey = e with respect to x gives us:

y + xy' + ey' = 0.

Evaluate the derivative at x=0.

Substituting x=0 into the derivative equation, we have:

y + 0y' + ey' = 0.

Simplifying, we get:

y' + ey' = 0.

Solve for y'.

Factoring out y' from the equation, we have:

y'(1 + e) = 0.

Since we are interested in finding the slope of the tangent line, we set the coefficient of y' equal to zero:

1 + e = 0.

Solve for y.

From the original equation xy + ey = e, we can substitute x=0 to find the y-coordinate:

0y + ey = e.

Simplifying, we get:

ey = e.

Dividing both sides by e, we have:

y = 1.

Write the equation of the tangent line.

We have found that the slope of the tangent line is y' = 0, and a point on the line is (0, 1). Using the point-slope form of a line, the equation of the tangent line is:

y - y1 = m(x - x1),

where (x1, y1) is the point (0, 1) and m is the slope of the tangent line:

y - 1 = 0(x - 0),

y - 1 = 0,

The area of square EFGH is one-fourth (1/4) of the area of square ABCD, or 25% of the total area.

To determine the fractional part of the area of square ABCD that is occupied by square EFGH, we can consider the geometric properties of the squares.

Let's assume that the side length of square ABCD is 1 unit for simplicity. Since E, F, G, and H are the midpoints of the sides AP, BP, CP, and DP respectively, the side length of square EFGH is half the side length of ABCD, which is 0.5 units.

The area of a square is calculated by squaring its side length. Therefore, the area of square ABCD is 1^2 = 1 square unit, and the area of square EFGH is (0.5)^2 = 0.25 square units.

To find the fractional part, we divide the area of square EFGH by the area of square ABCD: 0.25 / 1 = 0.25.

Therefore, the area of square EFGH is one-fourth (1/4) of the area of square ABCD, or 25% of the total area.

The value of c guaranteed by the Mean Value Theorem (MVT) for the function f(x) = √(81 - x^2) over the interval [0, 9] is approximately c = 6.0000.

The Mean Value Theorem states that if a function f(x) is continuous on the closed interval [a, b] and differentiable on the open interval (a, b), then there exists a value c in the interval (a, b) such that f'(c) = (f(b) - f(a))/(b - a). In this case, we have f(x) = √(81 - x^2) defined on the interval [0, 9].

To find the value of c, we first need to compute f'(x). Taking the derivative of f(x), we have f'(x) = (-x)/(√(81 - x^2)). Next, we evaluate f'(x) at the endpoints of the interval [0, 9]. At x = 0, f'(0) = 0, and at x = 9, f'(9) = -9/√(81 - 81) = undefined.

Since f(x) is not differentiable at x = 9, we cannot apply the Mean Value Theorem directly. However, we can observe that the function f(x) represents the upper semicircle of a circle with radius 9. The integral ∫9,0 f(x) dx represents the area under the curve from x = 0 to x = 9, which is equal to the area of the upper semicircle.

Using the formula for the area of a quarter circle, 1/4 * π * r^2, where r is the radius, we find that the area of the upper semicircle is 1/4 * π * 9^2 = 1/4 * π * 81 = 20.25π.

According to the Mean Value Theorem, there exists a value c in the interval [0, 9] such that f(c) = (1/(9 - 0)) * ∫9,0 f(x) dx. Therefore, f(c) = (1/9) * 20.25π. Solving for c, we get c ≈ 6.0000.

A. The integral ∫ C F⋅dr is 156.

B. The integral in part (A) does not depend on the path joining (0,0) to (1,6).

A. To evaluate the line integral ∫ C F⋅dr, we need to parameterize the path C and then calculate the dot product of the vector field F with the differential vector dr along the path.

The given path C is y = 6x^2, where x ranges from 0 to 1. We can parameterize this path as r(t) = ti + 6t^2j, where t ranges from 0 to 1.

Now, calculate F⋅dr:

F⋅dr = (3xy)i + (9y^2)j ⋅ (dx)i + (dy)j

= (3xt)(dx) + (9(6t^2)^2)(dy)

= 3xt(dx) + 324t^4(dy)

= 3xt(dt) + 324t^4(12t dt)

= (3t + 3888t^5)dt

Integrating this over the range t = 0 to 1:

∫ C F⋅dr = ∫[0,1] (3t + 3888t^5)dt

= [3t^2/2 + 3888t^6/6] from 0 to 1

= (3/2 + 3888/6) - (0/2 + 0/6)

= 156

Therefore, ∫ C F⋅dr = 156.

B. The integral in part (A) does not depend on the path joining (0,0) to (1,6). This is because the line integral of a conservative vector field only depends on the endpoints and not on the specific path taken between them. Since F = 3xyi + 9y^2j is a conservative vector field, the integral does not depend on the path and will have the same value for any path connecting the two points.

The Taylor polynomial of degree 4 for the function \( f(x) = \arctan(9x) \) at \( a = 0 \) is given by \( T_{4}(x) = x - \frac{81}{3}x^3 + \frac{729}{5}x^5 - \frac{6561}{7}x^7 \).

This polynomial is obtained by approximating the function \( f(x) \) with a polynomial of degree 4 around the point \( a = 0 \). The coefficients of the polynomial are determined using the derivatives of the function evaluated at \( a = 0 \), specifically the first, third, fifth, and seventh derivatives.

In this case, the first derivative of \( f(x) \) is \( \frac{9}{1 + (9x)^2} \), and evaluating it at \( x = 0 \) gives us \( 9 \). The third derivative is \( \frac{9 \cdot 2 \cdot 4 \cdot (9x)^2}{(1 + (9x)^2)^3} \), and evaluating it at \( x = 0 \) gives us \( 0 \).

The fifth derivative is \( \frac{9 \cdot 2 \cdot 4 \cdot (9x)^2 \cdot (1 + 9x^2) - 9 \cdot 2 \cdot 4 \cdot (9x)(2 \cdot 9x)(1 + (9x)^2)}{(1 + (9x)^2)^4} \), and evaluating it at \( x = 0 \) gives us \( 0 \). Finally, the seventh derivative is \( \frac{-9 \cdot 2 \cdot 4 \cdot (9x)(2 \cdot 9x)(1 + (9x)^2) - 9 \cdot 2 \cdot 4 \cdot (9x)(2 \cdot 9x)(1 + 9x^2)}{(1 + (9x)^2)^5} \), and evaluating it at \( x = 0 \) gives us \( -5832 \).

Plugging these values into the formula for the Taylor polynomial, we obtain \( T_{4}(x) = x - \frac{81}{3}x^3 + \frac{729}{5}x^5 - \frac{6561}{7}x^7 \). This polynomial provides an approximation of \( \arctan(9x) \) near \( x = 0 \) up to the fourth degree.

The absolute maximum value of f(x,y) subject to the given constraint is sqrt(4/3), and the absolute minimum value is 1.

To find the absolute maximum and minimum values of the function f(x,y)=x+y subject to the constraint 9x^2 - 9xy + 9y^2 = 9, we can use Lagrange multipliers method.

Let L(x, y, λ) = f(x, y) - λ(g(x, y)), where g(x, y) is the constraint function, i.e., g(x, y) = 9x^2 - 9xy + 9y^2 - 9.

Then, we have:

L(x, y, λ) = x + y - λ(9x^2 - 9xy + 9y^2 - 9)

Taking partial derivatives with respect to x, y, and λ, we get:

∂L/∂x = 1 - 18λx + 9λy = 0    (1)

∂L/∂y = 1 + 9λx - 18λy = 0    (2)

∂L/∂λ = 9x^2 - 9xy + 9y^2 - 9 = 0   (3)

Solving for x and y in terms of λ from equations (1) and (2), we get:

x = (2λ - 1)/(4λ^2 - 1)

y = (1 - λ)/(4λ^2 - 1)

Substituting these values of x and y into equation (3), we get:

[tex]9[(2λ - 1)/(4λ^2 - 1)]^2 - 9[(2λ - 1)/(4λ^2 - 1)][(1 - λ)/(4λ^2 - 1)] + 9[(1 - λ)/(4λ^2 - 1)]^2 - 9 = 0[/tex]

Simplifying the above equation, we get:

(36λ^2 - 28λ + 5)(4λ^2 - 4λ + 1) = 0

The roots of this equation are λ = 5/6, λ = 1/2, λ = (1 ± i)/2.

We can discard the complex roots since x and y must be real numbers.

For λ = 5/6, we get x = 1/3 and y = 2/3.

For λ = 1/2, we get x = y = 1/2.

Now, we need to check the values of f(x,y) at these critical points and the boundary of the constraint region (which is an ellipse):

At (x,y) = (1/3, 2/3), we have f(x,y) = 1.

At (x,y) = (1/2, 1/2), we have f(x,y) = 1.

On the boundary of the constraint region, we have:

9x^2 - 9xy + 9y^2 = 9

or, x^2 - xy + y^2 = 1

[tex]or, (x-y/2)^2 + 3y^2/4 = 1[/tex]

This is an ellipse centered at (0,0) with semi-major axis sqrt(4/3) and semi-minor axis sqrt(4/3).
