We have to set up the integral of \(f(r, \theta, z) = r_z\) over the region bounded above by the sphere \(r^2 + z^2 = 2\) and bounded below by the cone \(z = r\).The given region can be shown graphically as:

The intersection curve of the cone and sphere is a circle at \(z = r = 1\).

To find the range from Henry to the rabbit, we can use trigonometry and the given information about the bearings and distances. The range from Henry to the rabbit is approximately 38.3 meters.

Let's consider a right-angled triangle with Henry, the rabbit, and the distance between them as the hypotenuse of the triangle. We'll use the concept of bearings to determine the angles involved.

From the given information:

- George shines his flashlight on the rabbit along bearing 105°.

- Henry is standing 50 meters east and 50 meters south of George.

- Henry can see the same rabbit along bearing 055°.

First, let's find the angle between the line connecting George and Henry and the line connecting Henry and the rabbit:

Angle A = (180° - bearing from George to the rabbit) + bearing from Henry to the rabbit = (180° - 105°) + 55°  = 130°

Now, we can apply the sine rule to find the range from Henry to the rabbit. Let's denote the range as 'r':

sin(A) / r = sin(90°) / 50

Simplifying the equation:

sin(130°) / r = 1 / 50

Now, let's solve for 'r':

r = (50 * sin(130°)) / sin(90°)

Using a calculator:

r ≈ (50 * 0.766) / 1  ≈ 38.3 meters

Therefore, the range from Henry to the rabbit is approximately 38.3 meters.

The given equation represents a circle, the center of the circle is $(3, 5)$ and the radius is $\sqrt{21}$.

Given the equation $y^2 - 10y - x^2 + 6x = -13$, we can complete the square for the x and y terms to simplify the equation and identify its geometric representation.

Starting with the equation: $x^2 - 6x + y^2 - 10y = -13$

To complete the square, we add appropriate constants to both sides of the equation to create perfect squares. Adding $(9 + 25)$ on the left side, we get:

$(x^2 - 6x + 9) + (y^2 - 10y + 25) = -13 + 9 + 25$

Simplifying, we have:

$(x - 3)^2 + (y - 5)^2 = 21$

Therefore, the given equation can be written as $(x - 3)^2 + (y - 5)^2 = 21$.

This equation represents a circle in the xy-plane. By comparing it to the standard form equation for a circle, we can identify its center and radius.

The center of the circle is located at the coordinates $(3, 5)$, which are the opposite signs of the x and y terms in the equation. The radius of the circle can be determined by taking the square root of the value on the right side of the equation, which is $\sqrt{21}$. Hence, the center and radius of the given circle are $(3, 5)$ and $\sqrt{21}$, respectively.

After 10 seconds, plane A would be at an altitude of 564 meters, and plane B would be at an altitude of 240 meters.
The initial altitude of plane A is 414 meters, and it's gaining altitude at a rate of 15 meters per second.

Let's say we want to find the altitude after t seconds. We can use the formula: altitude of plane A = initial altitude + rate * time. So, the altitude of plane A after t seconds is 414 + 15t meters.

For plane B, it's just taking off, so its initial altitude is 0. It's gaining altitude at a rate of 24 meters per second. Similarly, the altitude of plane B after t seconds is 0 + 24t meters.

Now, if you want to compare their altitudes at a specific time, let's say after 10 seconds, you can substitute t = 10 into the equations. The altitude of plane A after 10 seconds would be

414 + 15 * 10 = 564 meters

The altitude of plane B after 10 seconds would be

0 + 24 * 10 = 240 meters.

(a) The time it takes for the pizza pan to cool down to 125°F is approximately 2.92 minutes.

(b) The time it takes for the pizza pan to cool down to 240°F is approximately 1.62 minutes.

To answer the given questions, we need to determine the time it takes for the pizza pan to cool down from the initial temperature to the desired temperatures.

(a) To find the time at which the temperature of the pan is 125°F, we can set up a proportion based on the cooling rate. Since the pan cools from 425°F to 300°F in 5 minutes, we can write:

425−125300−125=5x300−125425−125​=x5​,

where xx represents the time in minutes. Solving this proportion will give us the time needed for the pan to reach 125°F.

(b) Similarly, to find the time needed for the pan to reach 240°F, we can set up another proportion:

425−240300−240=5x300−240425−240​=x5​.

Solving this proportion will give us the time needed for the pan to reach 240°F.

(c) As time passes, the temperature of the pan gradually decreases. It follows a cooling rate, where the rate of temperature change is proportional to the temperature difference between the pan and its surroundings. Initially, the temperature decreases rapidly, and as the pan approaches room temperature, the rate of cooling slows down.

The given function is f(x) = −x2 + 2x − 5. Now, we need to find out whether the given function has minimum or maximum value. Let's solve the problem here.

Step 1:

First, we find the axis of symmetry, which is given by the formula x = -b / 2a, where a is the coefficient of x2, b is the coefficient of x, and c is the constant term. Here, a = -1, b = 2 and c = -5

So, the axis of symmetry is x = -b / 2a = -2 / 2(-1) = 1. The vertex lies on the axis of symmetry.

Step 2: To find whether the vertex is the minimum point or the maximum point, we check the sign of the coefficient of x2. If the coefficient is positive, the vertex is the minimum point. If the coefficient is negative, the vertex is the maximum point. Here, the coefficient of x2 is -1, which is negative.

Step 3: To find the maximum value of the function, we substitute the value of x in the function.

So, the maximum value of the function f(x) = −x2 + 2x − 5 is f(1) = −1 + 2 − 5 = -4.The maximum value of the function occurs at x = 1 and it is -4. the correct answer is Option b) Maximum -4; x = 1.

To address this situation, you can follow the revised simplex method to find an improved feasible basis and iteratively approach an optimal solution.

If the given basis b is neither primal feasible nor dual feasible in a linear programming problem, it means that the basic solution associated with b does not satisfy both the primal and dual feasibility conditions. In this case, you cannot directly use the current basis b to solve the problem.

To address this situation, you can follow the revised simplex method to find an improved feasible basis and iteratively approach an optimal solution. Here are the general steps:

1. Start with the given basis b and the associated basic solution.

2. Determine the entering variable by performing an optimality test using the current basis. The entering variable is typically selected based on the largest reduced cost (for the primal problem) or the smallest dual slack (for the dual problem).

3. Perform a ratio test to determine the leaving variable by selecting the variable that limits the movement of the entering variable and ensures dual feasibility.

4. Update the basis by replacing the leaving variable with the entering variable.

5. Recalculate the basic solution using the updated basis.

6. Repeat steps 2 to 5 until an optimal solution is reached or an alternate stopping criterion is met.

During this iterative process, the revised simplex method adjusts the basis at each step to improve feasibility and optimality. By identifying the entering and leaving variables based on optimality and feasibility criteria, the method gradually moves towards an optimal and feasible solution.

The sine function only takes values between -1 and 1. Since -2 is outside this range, there is no solution for sin(e) = -2 in this context.

To solve the system of equations:

r = 3(1 + sin(e))

r = 1 + 2sin(e)

The answer is: There is not enough information. As we only have the maximum allowable radius growth without popping, we cannot directly determine the rate at which helium can be pumped into the balloon.

To determine the rate at which helium can be pumped into the balloon without causing it to pop, we need to consider the rate of change of the volume with respect to time.

Given the equation for the volume of a sphere:

V = (4/3)πr³

where V is the volume and r is the radius, we can find the rate of change of the volume with respect to time by taking the derivative of the volume equation with respect to time:

dV/dt = (dV/dr) × (dr/dt)

Here, dV/dt represents the rate of change of the volume with respect to time, and dr/dt represents the rate of change of the radius with respect to time.

Since we are interested in finding the fastest rate at which we can pump helium into the balloon without popping it, we want to determine the maximum value of dV/dt.

Now, let's analyze the given information:

- We know that the fastest the radius can grow without popping is 2 cm.

Brooklyn can drive a maximum of 187 miles within her $50 budget.

To find the maximum number of miles Brooklyn can drive within her budget, we need to determine how much of her $50 budget is allocated to the base charge and how much is available for the additional mileage cost.

Let's denote the number of miles driven as 'm'. The additional mileage cost is given as 16 cents per mile. Therefore, the cost of mileage can be calculated as 0.16 * m.

Since Brooklyn has a budget of $50, we can set up the following equation to find the maximum number of miles:

According to the Question, The following results are:

(a) To find the radius and interval of convergence of the power series [tex]\sum \frac{2n}{n^2}* x^n,[/tex]

we can use the ratio test. The ratio test states that if the limit of the absolute value of the ratio of consecutive terms is L, then the series converges if L < 1 and diverges if L > 1.

Let's apply the ratio test to the given series:

L = lim_{n→∞} |(2(n+1)/(n+1)²) * x^{n+})| / |(2n/n²) * xⁿ|

= lim_{n→∞} |(2(n+1)x)/(n+1)²| / |(2x/n²)|

= lim_{n→∞} |2(n+1)x/n²| * |n²/(n+1)²|

= 2|x|

We require 2|x| 1 for the series to converge. Therefore, the radius of convergence is [tex]R = \frac{1}{2}.[/tex]

To determine the interval of convergence, we need to check the endpoints.

[tex]x=\frac{-1}{2},[/tex]  [tex]x = \frac{1}{2}.[/tex]

Since the series involves powers of x, we consider the endpoints as inclusive inequalities.

For [tex]x = \frac{-1}{2}[/tex]:

[tex]\sum (2n/n^2) * (\frac{-1}{2} -\frac{1}{2} )^n = \sum \frac{(-1)^n}{(n^2)}[/tex]

This is an alternating series with decreasing absolute values. By the Alternating Series Test, it converges.

For [tex]x = \frac{1}{2}[/tex]:

[tex]\sum (\frac{2n}{n^2} ) * (\frac{1}{2} )^n = \sum\frac{1}{n^2}[/tex]

This is a p-series with p = 2, and p > 1 implies convergence.

Hence, the interval of convergence is [tex]\frac{-1}{2} \leq x \leq \frac{1}{2} .[/tex]

(b) i. For f(x) = 3 - x, let's find its Taylor series expansion at x = 0.

To find the general term of the Taylor series, we can use the formula:

[tex]\frac{f^{n}(0)}{n!} * x^n[/tex]

Here, [tex]f^{n}(0)[/tex] denotes the nth derivative of f(x) evaluated at x = 0.

f(x) = 3 - x

f'(x) = -1

f''(x) = 0

f'''(x) = 0

...

The derivatives beyond the first term are zero. Thus, the Taylor series expansion for f(x) = 3 - x is:

[tex]f(x) = \frac{(3 - 0)}{0!}- \frac{(1) }{1!} * x + 0 + 0 + ...[/tex]

To simplify, We have

f(x) = 3 - x

The interval of convergence for this Taylor series is (-∞, ∞) since the function is a polynomial defined for all real numbers.

ii. For f(x) = (1 - x)³, let's find its Taylor series expansion at x = 0.

f(x) = (1 - x)³

f'(x) = -3(1 - x)²

f''(x) = 6(1 - x)

f'''(x) = -6

Evaluating the derivatives at x = 0, we have:

f(0) = 1

f'(0) = -3

f''(0) = 6

f'''(0) = -6

Using the general term formula, the Taylor series expansion for f(x) = (1 - x)³ is:

f(x) = 1 - 3x + 6x² - 6x³ + ...

The interval of convergence for this Taylor series is (-∞, ∞) since the function is a polynomial defined for all real numbers.

iii. For f(x) = ln(3 - x), let's find its Taylor series expansion at x = 0.

f(x) = ln(3 - x)

f'(x) = -1 / (3 - x)

f''(x) = 1 / (3 - x)²

f'''(x) = -2 / (3 - x)³

f''''(x) = 6 / (3 - x)⁴

Evaluating the derivatives at x = 0, we have:

[tex]f(0) = ln(3)\\\\f'(0) =\frac{-1}{3} \\\\f''(0) = \frac{1}{9} \\\\f'''(0) =\frac{-2}{27} \\\\f''''(0) = \frac{6}{81}\\\\f''''(0)= 2/27[/tex]

Using the general term formula, the Taylor series expansion for f(x) = ln(3 - x) is:

[tex]f(x) = ln(3) - (\frac{1}{3})x + (\frac{1}{9})x^2 - (\frac{2}{27})x^3 + (\frac{2}{27})x^4 - ...[/tex]

(c) To calculate the Taylor polynomial of degree 5 for the function f(x) = x² + (c * x)/(10⁸) at x = 1, you can use the Taylor series expansion formula:

[tex]T_n(x) = f(a) + f'(a)(x - a) + \frac{(f''(a)(x - a)^2)}{2!} + \frac{(f'''(a)(x - a)^3)}{3!} + ... + \frac{(f^(n)(a)(x - a)^n)}{n!}[/tex]

Once you have the Taylor polynomial of degree 5, you can use it to plot the function f(x) and the Taylor polynomials of degrees 1, 2, and 3 at x = 1 over the interval 0 ≤ x ≤ 2. You can choose a suitable range of values for x and substitute them into the polynomial equations to obtain the corresponding y-values.

b. (go f)(x) = 50x² - 60x + 13

c. (fog)(2) = 12

d. (go f)(2) = 153

The given functions are,

f(x)=5x-3

g(x) = 2x² -5

a. To find (fog)(x), we need to first apply g(x) to x, and then apply f(x) to the result. So we have:

(fog)(x) = f(g(x)) = f(2x² - 5)

                         = 5(2x² - 5) - 3

                         = 10x² - 28

b. To find (go f)(x), we need to first apply f(x) to x, and then apply g(x) to the result. So we have:

(go f)(x) = g(f(x)) = g(5x - 3)

                         = 2(5x - 3)² - 5

                         = 2(25x² - 30x + 9) - 5

                         = 50x² - 60x + 13

c. To find (fog)(2), we simply substitute x = 2 into the expression we found for (fog)(x):

(fog)(2) = 10(2)² - 28

           = 12

d. To find (go f)(2), we simply substitute x = 2 into the expression we found for (go f)(x):

(go f)(2) = 50(2)² - 60(2) + 13

             = 153

Integrating \(6x + y\) with respect to \(x\) while treating \(y\) as a constant, we obtain:\[\int (6x + y) \, dx = 3x^2 + xy + C\]

Next, we integrate this expression with respect to \(y\) while considering \(x\) as a constant. Since we have the limits of integration for both \(x\) and \(y\), we can substitute the limits into the integral expression:

\[\int_{-2}^{-1} (3x^2 + xy + C) \, dy\]

Evaluating this integral gives us:

\[\left[3x^2y + \frac{1}{2}xy^2 + Cy\right]_{-2}^{-1}\]

Substituting the limits, we have:

\[3x^2(-1) + \frac{1}{2}x(-1)^2 + C(-1) - \left[3x^2(-2) + \frac{1}{2}x(-2)^2 + C(-2)\right]\]

Simplifying further, we have:

\[-3x^2 - \frac{1}{2}x + C + 6x^2 + 2x^2 + 2C\]

Combining like terms, we obtain:

\[5x^2 + \frac{3}{2}x + 3C\]

Now, we can evaluate this expression within the limits of integration for \(x\), which are from 0 to 6:

\[\left[5x^2 + \frac{3}{2}x + 3C\right]_0^6\]

Substituting the limits, we get:

\[5(6)^2 + \frac{3}{2}(6) + 3C - (5(0)^2 + \frac{3}{2}(0) + 3C)\]

Simplifying further, we have:

\[180 + 9 + 3C - 0 - 0 - 3C\]

Combining like terms, we find that:

\[180 + 9 = 189\]

Therefore, the value of the given double integral is 189.

Using Newton's method, we can approximate the root of the equation 2.2x^5 - 4.4x^3 + 1.3x^2 - 0.7x - 0.8 = 0 in the interval [-2, -1]. The approximate value of the root, correct to six decimal places, is x = -1.696722.

Newton's method is an iterative numerical method used to approximate the roots of an equation. We start with an initial guess and refine it using the formula xᵢ₊₁ = xᵢ - f(xᵢ)/f'(xᵢ), where f(x) represents the given equation and f'(x) is the derivative of f(x).

To approximate the root in the interval [-2, -1], we first need to choose a suitable initial guess within that interval. Let's choose x₀ = -1.5 as our initial guess.

Next, we need to calculate the derivatives of the equation. The derivative of f(x) = 2.2x^5 - 4.4x^3 + 1.3x^2 - 0.7x - 0.8 with respect to x is f'(x) = 11x^4 - 13.2x^2 + 2.6x - 0.7.

Using the initial guess x₀ = -1.5, we iteratively apply the Newton's method formula: x₁ = x₀ - f(x₀)/f'(x₀), x₂ = x₁ - f(x₁)/f'(x₁), and so on.

By repeating this process, we can approximate the root of the equation within the given interval. After several iterations, we find that the approximate value of the root, correct to six decimal places, is x = -1.696722.

Therefore, using Newton's method, we have successfully approximated the root of the equation 2.2x^5 - 4.4x^3 + 1.3x^2 - 0.7x - 0.8 = 0 in the interval [-2, -1] to a high degree of accuracy.

Based on the given information, approximately 5736 number of people responded NO in the survey. It is important to note that this is an approximation since we are working with percentages and rounding may be involved.

In a survey where 9900 people were asked a YES or NO question, 42% of the respondents answered YES. The task is to determine the number of people who said NO based on this information.

To solve the problem, we first need to understand the concept of percentages. Percentages represent a portion of a whole, where 100% represents the entire group. In this case, the 42% who answered YES represents a portion of the total surveyed population.

To find the number of people who said NO, we need to calculate the remaining percentage, which represents the complement of the YES responses. The complement of 42% is 100% - 42% = 58%.

To determine the number of people who said NO, we multiply the remaining percentage by the total number of respondents. Thus, 58% of 9900 is equal to (58/100) * 9900 = 0.58 * 9900 = 5736.

Therefore, based on the given information, approximately 5736 people responded NO in the survey. It is important to note that this is an approximation since we are working with percentages and rounding may be involved.

This calculation highlights the importance of understanding percentages and their relation to a whole population. It also demonstrates how percentages can be used to estimate the number of responses in a survey or to determine the distribution of answers in a given dataset.
