To prove the quotient rule using the product rule and chain rule, we can express the quotient as a product with the reciprocal of the denominator. By applying the product rule and chain rule to this expression, we can derive the quotient rule.

Let's consider the function f(x) = h(x)/g(x), where g(x) ≠ 0.

We can rewrite f(x) as f(x) = h(x)⋅[g(x)]^(-1).

Now, using the product rule, we differentiate f(x) with respect to x:

f'(x) = [h(x)⋅[g(x)]^(-1)]' = h(x)⋅[g(x)]^(-1)' + [h(x)]'⋅[g(x)]^(-1).

The derivative of [g(x)]^(-1) can be found using the chain rule:

[g(x)]^(-1)' = -[g(x)]^(-2)⋅[g(x)]'.

Substituting this into the previous expression, we have:

f'(x) = h(x)⋅(-[g(x)]^(-2)⋅[g(x)]') + [h(x)]'⋅[g(x)]^(-1).

Simplifying further, we obtain:

f'(x) = -h(x)⋅[g(x)]^(-2)⋅[g(x)]' + [h(x)]'⋅[g(x)]^(-1).

To express the derivative in terms of the original function, we multiply by g(x)/g(x):

f'(x) = -h(x)⋅[g(x)]^(-2)⋅[g(x)]'⋅g(x)/g(x) + [h(x)]'⋅[g(x)]^(-1)⋅g(x)/g(x).

Simplifying further, we have:

f'(x) = [-h(x)⋅[g(x)]'⋅g(x) + [h(x)]'⋅g(x)]/[g(x)]^2.

Finally, noticing that -h(x)⋅[g(x)]'⋅g(x) + [h(x)]'⋅g(x) can be expressed as [h(x)]'⋅g(x) - h(x)⋅[g(x)]' (by rearranging terms), we obtain the quotient rule:

f'(x) = [h(x)]'⋅g(x) - h(x)⋅[g(x)]'/[g(x)]^2.

Therefore, we have proven the quotient rule using the product rule and chain rule.

A) we would send Order A to Factory 3.

B) we would send both Order B and Order C to Factory 3.

B 7,000 Factory 3

C 30,000 Factory 3

Total number of units produced for the company today: 37,000

Average cost per unit for all production today: $9.00

To make decisions about which factory to send the orders to on Monday and Tuesday, we need to compare the costs per unit for each factory and consider the total number of units to be produced. Let's go through each day's scenario and make the production decisions.

a) Monday: Order A for 15,000 units

To decide which factory to send the order to, we compare the costs per unit for each factory. We select the factory with the lowest cost per unit to minimize the average cost per unit for the company.

Let's assume the costs per unit for each factory are as follows:

Factory 1: $10 per unit

Factory 2: $12 per unit

Factory 3: $9 per unit

To calculate the total cost for each factory, we multiply the cost per unit by the number of units:

Factory 1: $10 * 15,000 = $150,000

Factory 2: $12 * 15,000 = $180,000

Factory 3: $9 * 15,000 = $135,000

Based on the calculations, Factory 3 has the lowest total cost for producing 15,000 units, with a total cost of $135,000. Therefore, we would send Order A to Factory 3.

b) Tuesday: Order B for 7,000 units and Order C for 30,000 units

We have two options: sending each order to a separate factory or sending both orders to the same factory. We need to compare the average cost per unit for each option and select the one that results in the lowest average cost per unit.

Let's assume the costs per unit for each factory remain the same as in the previous example. We will calculate the average cost per unit for each option:

Option 1: Sending orders to separate factories

For Order B (7,000 units):

Average cost per unit = ($10 * 7,000) / 7,000 = $10

For Order C (30,000 units):

Average cost per unit = ($9 * 30,000) / 30,000 = $9

Total number of units produced for the company today = 7,000 + 30,000 = 37,000

Average cost per unit for all production today = ($10 * 7,000 + $9 * 30,000) / 37,000 = $9.43 (rounded to two decimal places)

Option 2: Sending both orders to the same factory (Factory 3)

For Orders B and C (37,000 units):

Average cost per unit = ($9 * 37,000) / 37,000 = $9

Comparing the two options, we see that both options have the same average cost per unit of $9. However, sending both orders to Factory 3 simplifies the production process by consolidating the orders in one factory. Therefore, we would send both Order B and Order C to Factory 3.

Production Report for Tuesday:

Order # of Units Factory

B   7,000      Factory 3

C  30,000    Factory 3

The partial derivative ∂f/∂x of the function f(x, y) = √(16x + y^3) with respect to x is given by: ∂f/∂x = 8 / √(16x + y^3)

To find the partial derivative of f(x, y) with respect to x, denoted as ∂f/∂x, we treat y as a constant and differentiate f(x, y) with respect to x.

f(x, y) = √(16x + y^3)

To find ∂f/∂x, we differentiate f(x, y) with respect to x while treating y as a constant.

∂f/∂x = ∂/∂x (√(16x + y^3))

To differentiate the square root function, we can use the chain rule. Let u = 16x + y^3, then f(x, y) = √u.

∂f/∂x = ∂/∂x (√u) = (1/2) * (u^(-1/2)) * ∂u/∂x

Now, we need to find ∂u/∂x:

∂u/∂x = ∂/∂x (16x + y^3) = 16

Plugging this back into the expression for ∂f/∂x:

∂f/∂x = (1/2) * (u^(-1/2)) * ∂u/∂x

      = (1/2) * ((16x + y^3)^(-1/2)) * 16

      = 8 / √(16x + y^3)

Therefore, the partial derivative ∂f/∂x of the function f(x, y) = √(16x + y^3) with respect to x is given by:

∂f/∂x = 8 / √(16x + y^3)

The market demand function for ice cream in this 2-person economy is x = 19 - 5p, where x represents the total quantity of ice cream demanded and p represents the price per scoop.

In the given problem, we are asked to determine the market demand function for ice cream in a 2-person economy, where Michael and Sara have individual demand functions that are linear. We are given their consumption quantities at two different price levels and the rate at which their consumption changes with price. The market demand function represents the total quantity of ice cream demanded by both individuals at different price levels.

Let's denote the price per scoop as p and the quantity demanded by Michael and Sara as xM and xS, respectively. We are given the following information:

At p = 0, xM = 7 and xS = 12.

For every 1 Swiss Franc increase in price, xM decreases by 1 and xS decreases by 4.

Based on this information, we can write the demand functions for Michael and Sara as follows:

xM = 7 - p

xS = 12 - 4p

To find the market demand function, we need to sum up the individual demands:

xM + xS = (7 - p) + (12 - 4p)

= 7 + 12 - p - 4p

= 19 - 5p

Therefore, the market demand function for ice cream in this 2-person economy is:

x = 19 - 5p

This equation represents the total quantity of ice cream demanded by both Michael and Sara at different price levels. As the price per scoop increases, the total quantity demanded decreases linearly at a rate of 5 scoops per 1 Swiss Franc increase in price.

In conclusion, the market demand function for ice cream in this 2-person economy is x = 19 - 5p, where x represents the total quantity of ice cream demanded and p represents the price per scoop.

To evaluate the integral ∫√(5+4x-x²)dx, we can complete the square in the expression 5+4x-x². We can rewrite it as (-x²+4x+5) = (-(x²-4x) + 5) = (-(x²-4x+4) + 9) = -(x-2)² + 9.

Now we have the expression √(5+4x-x²) = √(-(x-2)² + 9). We can make a substitution to create a quantity of the form a²-u². Let u = x-2, then du = dx.

Substituting these values into the integral, we get ∫√(5+4x-x²)dx = ∫√(-(x-2)² + 9)dx = ∫√(9 - (x-2)²)dx.

Next, we can apply the formula for the integral of √(a²-u²)du, which is (2/3)(a²-u²)^(3/2) - (2/3)u√(a²-u²) + C. In our case, a = 3 and u = x-2.

Substituting back, we have ∫√(5+4x-x²)dx = (2/3)(5+4x-x²)^(3/2) - (2/3)(x-2)√(5+4x-x²) + C.

Simplifying further, we get ∫√(5+4x-x²)dx = (2/3)(5+4x-x²)^(3/2) - (8/3)(x-2)√(5+4x-x²) + C.

Finally, we can rewrite (x-2) as (2x-1)/√6 and simplify the expression to obtain the final answer: ∫√(5+4x-x²)dx = (2/3)(5+4x-x²)^(3/2) - (8/3)arcsin((2x-1)/√6) + C, where C is the constant of integration.

The partial derivatives ∂T/∂U and ∂U/∂T are approximately -7.548 and -6.416 respectively.

To calculate the partial derivatives ∂T/∂U and ∂U/∂T using implicit differentiation of the equation (TU−V)² ln(W−UV) = ln(13), we'll differentiate both sides of the equation with respect to T and U separately.

First, let's find ∂T/∂U:

Differentiating both sides of the equation with respect to U:

(2(TU - V)ln(W - UV)) * (T * dU/dU) + (TU - V)² * (1/(W - UV)) * (-U) = 0

Since dU/dU equals 1, we can simplify:

2(TU - V)ln(W - UV) + (TU - V)² * (-U) / (W - UV) = 0

Now, substituting the values T = 3, U = 4, V = 13, and W = 65 into the equation:

2(3 * 4 - 13)ln(65 - 3 * 4) + (3 * 4 - 13)² * (-4) / (65 - 3 * 4) = 0

Simplifying further:

2(-1)ln(53) + (-5)² * (-4) / 53 = 0

-2ln(53) + 20 / 53 = 0

To express this fraction in symbolic notation, we can write:

∂T/∂U = (20 - 106ln(53)) / 53

Substituting ln(53) = 3.9703 into the equation, we get:

∂T/∂U = (20 - 106 * 3.9703) / 53

= (20 - 420.228) / 53

= -400.228 / 53

≈ -7.548

Now, let's find ∂U/∂T:

Differentiating both sides of the equation with respect to T:

(2(TU - V)ln(W - UV)) * (dT/dT) + (TU - V)² * (1/(W - UV)) * U = 0

Again, since dT/dT equals 1, we can simplify:

2(TU - V)ln(W - UV) + (TU - V)² * U / (W - UV) = 0

Substituting the values T = 3, U = 4, V = 13, and W = 65:

2(3 * 4 - 13)ln(65 - 3 * 4) + (3 * 4 - 13)² * 4 / (65 - 3 * 4) = 0

Simplifying further:

2(-1)ln(53) + (-5)² * 4 / 53 = 0

-2ln(53) + 80 / 53 = 0

To express this fraction in symbolic notation:

∂U/∂T = (80 - 106ln(53)) / 53

Substituting ln(53) = 3.9703 into the equation, we get:

∂U/∂T = (80 - 106 * 3.9703) / 53

= (80 - 420.228) / 53

= -340.228 / 53

≈ -6.416

Therefore, the partial derivatives are:

∂T/∂U = -7.548

∂U/∂T = -6.416

Therefore, the values of ∂T/∂U and ∂U/∂T are approximately -7.548 and -6.416, respectively.

The maximum value of f(x,y) is 1 and the minimum value of f(x,y) is -1.

Lagrange multipliers are used to solve optimization problems in which we are trying to maximize or minimize a function subject to constraints.

Let's use Lagrange multipliers to find the maximum and minimum values of the function

f(x,y) = x² - y²

subject to the constraint

x² + y² = 1.

Here is the solution:

Firstly, we set up the equation using Lagrange multiplier method:

f(x,y) = x² - y² + λ(x² + y² - 1)

Next, we differentiate the equation with respect to x, y and λ.

∂f/∂x = 2x + 2λx

= 0

∂f/∂y = -2y + 2λy

= 0

∂f/∂λ = x² + y² - 1

= 0

From the above equations, we obtain that:

x(1 + λ) = 0

y(1 - λ) = 0

x² + y² = 1

Either x = 0 or λ = -1. If λ = -1, then y = 0.

Similarly, either y = 0 or λ = 1. If λ = 1, then x = 0.

Therefore, we obtain that the four possible points are (1,0), (-1,0), (0,1) and (0,-1).

Next, we need to find the values of f(x,y) at these points.

f(1,0) = 1

f(-1,0) = 1

f(0,1) = -1

f(0,-1) = -1

Therefore, the maximum value of f(x,y) is 1 and the minimum value of f(x,y) is -1.

To sketch the root locus for the given unity feedback system, we follow the steps of the root locus construction:

1. Identify the open-loop transfer function: L(s) = K - s + 1 / (s^2 + 4s - 5)

2. Determine the poles and zeros of the open-loop transfer function. The poles are obtained by setting the denominator of L(s) equal to zero, which gives s^2 + 4s - 5 = 0.

3. Determine the branches of the root locus. Since there are two poles, there will be two branches starting from the poles. The branches will move towards the zeros and/or to infinity.

4. Determine the angles of departure and arrival for the branches. The angle of departure from a pole is given by the sum of the angles of the open-loop transfer function at that pole.

5. Determine the real-axis segments. The real-axis segments of the root locus occur between the real-axis intersections of the branches. In this case, there are two real-axis segments.

6. Determine the breakaway and break-in points. These are the points where the branches of the root locus either originate or terminate. The breakaway points occur when the derivative of the characteristic equation with respect to s is zero.

Based on the sketch of the root locus, we can answer the following questions:

A. The system without feedback is not stable because the poles of the open-loop transfer function have positive real parts.

B. Under unity feedback, the closed-loop system will be stable if the gain, K, lies to the left of the root locus branches and does not encircle any poles of the open-loop transfer function.

C. Assuming stability, the steady-state error for a unit step change in the reference signal will be zero because there is a pole at the origin (zero steady-state error for unity feedback).

D. With K = 6, the dominant pole approximation may hold since the other poles are further away. To estimate the 1% settling time, we can calculate the settling time of the dominant pole, which is the pole closest to the imaginary axis.

To find the sum of the first 8 terms of the sequence −1, 1, 3, ..., we need to determine the pattern of the sequence. From the given terms, we can observe that each term is obtained by adding 2 to the previous term.

Starting with the first term -1, we can calculate the subsequent terms as follows:

-1, -1 + 2 = 1, 1 + 2 = 3, 3 + 2 = 5, 5 + 2 = 7, 7 + 2 = 9, 9 + 2 = 11, 11 + 2 = 13.

Now, we have the values of the first 8 terms: -1, 1, 3, 5, 7, 9, 11, 13.

To find the sum of these terms, we can use the formula for the sum of an arithmetic series:

Sn = (n/2)(a1 + an),

where Sn is the sum of the first n terms, a1 is the first term, and an is the nth term.

To determine the intervals on which f(x) is continuous, we will use the following approach:

The denominator of the given function should not be equal to zero as this would make the function undefined.

Thus, the first step is to equate the denominator to zero and solve for x:

x² - 5 = 0⇒ x = ±√5

The function f(x) is undefined at x = ±√5.

Now, let's use these critical points and any additional points where the function may not be continuous to divide the real line into intervals. We will then test the sign of the function in each interval to determine where it is positive or negative. This will help us find where the function is continuous.

1. Consider x < -√5. In this interval, we have:

x² - 4 > 0 and x² - 5 < 0

Hence, the function can be written as:

f(x) = ln(|x² - 4|) / |x² - 5|

Now, for x < -√5, we have:

x² - 4 > 0 ⇒ |x² - 4| = x² - 4x² - 5 < 0 ⇒ |x² - 5| = -(x² - 5)

Using these, we get: f(x) = ln(x² - 4) / -(x² - 5) = -ln(x² - 4) / (x² - 5)

As the numerator and denominator of f(x) are both negative in this interval, f(x) is positive.

Hence, f(x) is continuous on (-∞, -√5).2. Consider -√5 < x < √5.

In this interval, we have: x² - 4 > 0 and x² - 5 > 0

Hence, the function can be written as: f(x) = ln(x² - 4) / (x² - 5)

The numerator and denominator of f(x) are both negative in this interval.

Thus, f(x) is negative in this interval. Hence, f(x) is continuous on (-√5, √5).3. Consider x > √5.

In this interval, we have:x² - 4 > 0 and x² - 5 > 0

Hence, the function can be written as: f(x) = ln(x² - 4) / (x² - 5)

The numerator and denominator of f(x) are both positive in this interval. Thus, f(x) is positive in this interval.

Hence, f(x) is continuous on (√5, ∞).Therefore, f(x) is continuous on the interval (-∞, -√5) U (-√5, √5) U (√5, ∞).

To determine the divergence of the vector field \( \vec{U} = (xy \sin z)\hat{\imath} + (y^2 \sin x)\hat{j} + (z^2 \sin xy)\hat{k} \) at the point \((0, \pi, \pi)\), we need to compute the divergence operator \( \nabla \cdot \vec{U} \).

The divergence operator is defined as the sum of the partial derivatives of each component of the vector field with respect to their corresponding variables. In this case, we have:

\[

\begin{aligned}

\nabla \cdot \vec{U} &= \frac{\partial}{\partial x}(xy \sin z) + \frac{\partial}{\partial y}(y^2 \sin x) + \frac{\partial}{\partial z}(z^2 \sin xy) \\

&= y \sin z + 2y \sin x + 2z \sin xy.

\end{aligned}

\]

To evaluate the divergence at the given point \((0, \pi, \pi)\), we substitute \(x = 0\), \(y = \pi\), and \(z = \pi\) into the expression for the divergence:

\[

\begin{aligned}

\nabla \cdot \vec{U} &= (\pi)(\sin \pi) + 2(\pi)(\sin 0) + 2(\pi)(\sin 0 \cdot \pi) \\

&= 0 + 2(0) + 2(0) \\

&= 0.

\end{aligned}

\]

Therefore, the divergence of the vector field \( \vec{U} \) at the point \((0, \pi, \pi)\) is zero.

The divergence measures the "outwardness" of the vector field at a given point. A divergence of zero indicates that the vector field is neither spreading out nor converging at the point \((0, \pi, \pi)\). In other words, the net flow of the vector field across any small closed surface around the point is zero.

Thus, the correct answer is A. 72.85 m².

To find the area of a right spherical triangle, we can use the formula:

Area = r²(A + B + C - π),

where r is the radius of the sphere and A, B, C are the angles of the triangle.

Given that C = 90°, we have:

A = 72°27' = 72 + (27/60) ≈ 72.45°

B = 61°49' = 61 + (49/60) ≈ 61.82°

Substituting these values into the formula, along with C = 90° and the radius r = 10 m, we get:

Area = (10)²(72.45° + 61.82° + 90° - π)

≈ (100)(224.27° - π)

Now, we need to convert the result from degrees to radians since the formula expects angles in radians. There are π radians in 180°, so we divide by 180 to convert degrees to radians:

Area ≈ (100)(224.27° - π) * (π/180)

≈ (100)(224.27 - π) * (π/180)

Calculating the approximate value:

We need to evaluate the integral ∫(11x - 12) / (x - 2) * x * (x + 3) dx using integration by partial fractions. The integral of A / (x - 2) is A ln |x - 2|, the integral of B / x is B ln |x|, and the integral of C / (x + 3) is C ln |x + 3|

To integrate the given rational function, we first factorize the denominator, x * (x - 2) * (x + 3), into linear factors. The factors are (x - 2), x, and (x + 3).

Next, we express the integrand as a sum of partial fractions:

(11x - 12) / (x - 2) * x * (x + 3) = A / (x - 2) + B / x + C / (x + 3),

where A, B, and C are constants to be determined.

To find A, B, and C, we can use the method of equating coefficients or by finding a common denominator and equating the numerators.

Once we have determined the values of A, B, and C, we can integrate each term separately. The integral of A / (x - 2) is A ln |x - 2|, the integral of B / x is B ln |x|, and the integral of C / (x + 3) is C ln |x + 3|.

Finally, we sum up the individual integrals to get the final result.

In conclusion, by decomposing the rational function into partial fractions and integrating each term separately, we can evaluate the given integral.

The solution of the differential equation is y’+3y=t+e^-2t.

We have given the differential equation as y’+3y=t+e^-2t.

Now we can find the integrating factor:

mu(t) = e^(integral of p(t) dt)mu(t)

= e^(3t)

Now multiplying both sides with integrating factor gives:

=  (e^(3t) y(t))'

= te^(3t) + e^(t) e^(-2t)

Integrating both sides gives:

e^(3t)y(t) = (1/3)te^(3t) - (1/5) e^(t) e^(-2t) + c(e^3t)e^(3t)y(t)

= (1/3)te^(3t) - (1/5) e^(t-2t) + ce^(3t)

As t → [infinity], the term e^3t grows much faster than the other terms, so we can ignore the other two terms.

The equation of the sphere passing through the point (6, -2, 3) with center (-1, 2, 1) is[tex](x + 1)^2 + (y - 2)^2 + (z - 1)^2[/tex] = 70. The intersection of this sphere with the yz-plane is a circle centered at (0, 2, 1) with a radius of √69.

To find the equation of the sphere, we can use the general equation of a sphere: [tex](x - h)^2 + (y - k)^2 + (z - l)^2 = r^2[/tex], where (h, k, l) is the center of the sphere and r is its radius. Given that the center of the sphere is (-1, 2, 1), we have[tex](x + 1)^2 + (y - 2)^2 + (z - 1)^2 = r^2[/tex]. To determine r, we substitute the coordinates of the given point (6, -2, 3) into the equation: [tex](6 + 1)^2 + (-2 - 2)^2 + (3 - 1)^2 = r^2[/tex]. Simplifying, we get 49 + 16 + 4 = [tex]r^2[/tex], which gives us [tex]r^2[/tex] = 69. Therefore, the equation of the sphere is[tex](x + 1)^2 + (y - 2)^2 + (z - 1)^2[/tex] = 70.

To find the intersection of the sphere with the yz-plane, we set x = 0 in the equation of the sphere.

In the given radioactive decay function, t represents time in years, and m(t) represents the mass of the radioactive substance at time t. The mass of the substance reaches 25 grams at approximately t = 899.595 years.

To solve for t, we can set the mass function equal to 25 grams and solve for t:

25 = 100[tex]e^(-t/650)[/tex].

To isolate [tex]e^(-t/650)[/tex], we divide both sides by 100:

25/100 = [tex]e^(-t/650)[/tex].

Simplifying further:

1/4 = [tex]e^(-t/650)[/tex].

To eliminate the exponential function, we can take the natural logarithm (ln) of both sides:

ln(1/4) = ln([tex]e^(-t/650)[/tex]).

Using the property of logarithms, ln([tex]e^x[/tex]) = x, we can simplify the equation:

ln(1/4) = -t/650.

Now, we can solve for t by multiplying both sides by -650:

-650 * ln(1/4) = t.

Using a calculator to evaluate ln(1/4) ≈ -1.3863 and performing the multiplication:

t ≈ -650 * (-1.3863)

t ≈ 899.595.

Therefore, the mass of the substance reaches 25 grams at approximately t = 899.595 years.

The exact answer to the integral ∫e^(3√s)/√s ds is (2/9) e^(3√s) (3√s - 1) + C.To solve the integral ∫e^(3√s)/√s ds, we can use a substitution. Let u = √s, then du = (1/2√s) ds. Rearranging, we have 2√s du = ds.

Now, we can rewrite the integral in terms of u:

∫e^(3√s)/√s ds = ∫e^(3u) (2√s du)

Substituting back s = u^2, and ds = 2√s du, we get:

∫e^(3u) (2√s du) = ∫e^(3u) (2u) du

Now, we can evaluate this integral:

∫e^(3u) (2u) du = 2 ∫u e^(3u) du

To integrate this expression, we can use integration by parts. Let u = u and dv = e^(3u) du. Then, du = du and v = (1/3) e^(3u).

Applying integration by parts, we have:

2 ∫u e^(3u) du = 2 (u * (1/3) e^(3u) - ∫(1/3) e^(3u) du)

Simplifying the right-hand side, we have:

2 (u * (1/3) e^(3u) - (1/3) ∫e^(3u) du)

Integrating ∫e^(3u) du gives us (1/3) e^(3u):

a) The definite integral for the area of the upper half of a circle with radius \(r\) can be written as: [tex]\[A = \int_{-r}^{r} \sqrt{r^2 - x^2} \, dx\][/tex].

b) To solve this integral, we can use the substitution \(x = r \cos(t)\). The bounds of integration will also change accordingly. When \(x = -r\), we have \(t = \pi\) (upper bound), and when \(x = r\), we have \(t = 0\) (lower bound). The new definite integral becomes:

[tex]\[A = \int_{\pi}^{0} \sqrt{r^2 - (r \cos(t))^2} \, (-r \sin(t)) \, dt\][/tex]

Simplifying:

[tex]\[A = -r^2 \int_{\pi}^{0} \sin(t) \sqrt{1 - \cos^2(t)} \, dt\][/tex]

c) Now, we can compute the integral to its completion using the definite integral. Note that the integrand [tex]\(\sin(t) \sqrt{1 - \cos^2(t)}\)[/tex] simplifies to \(\sin(t) \sin(t)\) due to the trigonometric identity [tex]\(\sin^2(t) + \cos^2(t) = 1\)[/tex]. The negative sign can be factored out as well. Therefore, the definite integral becomes:

[tex]\[A = -r^2 \int_{\pi}^{0} \sin^2(t) \, dt\][/tex]

Using the trigonometric identity \(\sin^2(t) = \frac{1}{2}(1 - \cos(2t))\), the integral simplifies to:

[tex]\[A = -\frac{r^2}{2} \int_{\pi}^{0} (1 - \cos(2t)) \, dt\][/tex]

Evaluating the integral:

[tex]\[A = -\frac{r^2}{2} \left[t - \frac{1}{2}\sin(2t)\right]_{\pi}^{0}\][/tex]

Plugging in the bounds, we get:

[tex]\[A = -\frac{r^2}{2} \left[0 - \frac{1}{2}\sin(2\pi) - (\pi - \frac{1}{2}\sin(2\pi))\right]\][/tex]

Since [tex]\(\sin(2\pi) = 0\)[/tex], the expression simplifies to:

[tex]\[A = -\frac{r^2}{2} (-\pi) = \frac{r^2\pi}{2}\][/tex]

The equation of the tangent line to the curve y = x^2 + 1/(x^2 + x + 1) at the point (1, 0) is y = 2x - 2.

To find the equation of the tangent line, we need to determine the slope of the tangent line at the given point and then use the point-slope form of a linear equation.

First, let's find the derivative of the given function y = x^2 + 1/(x^2 + x + 1). Using the power rule and the quotient rule, we find that the derivative is y' = 2x - (2x + 1)/(x^2 + x + 1)^2.

Next, we substitute x = 1 into the derivative to find the slope of the tangent line at the point (1, 0). Plugging in x = 1 into the derivative, we get y' = 2(1) - (2(1) + 1)/(1^2 + 1 + 1)^2 = 1/3.

Now we have the slope of the tangent line, which is 1/3. Using the point-slope form of a linear equation, we can write the equation of the tangent line as y - 0 = (1/3)(x - 1), which simplifies to y = 2x - 2.

Therefore, the equation of the tangent line to the curve y = x^2 + 1/(x^2 + x + 1) at the point (1, 0) is y = 2x - 2.

The first four terms of the binomial series for (1 + 10x^2)^3 are 1, 30x^2, 300x^4, and 1000x^6.

To find the first four terms of the binomial series for the function (1 + 10x^2)^3, we can expand it using the binomial theorem.

The binomial theorem states that for a binomial (a + b)^n, the expansion is given by:

(a + b)^n = C(n, 0)a^n b^0 + C(n, 1)a^(n-1) b^1 + C(n, 2)a^(n-2) b^2 + ... + C(n, r)a^(n-r) b^r + ...

where C(n, r) represents the binomial coefficient "n choose r".

In this case, the function is (1 + 10x^2)^3, so we have:

(1 + 10x^2)^3 = C(3, 0)(1)^3 (10x^2)^0 + C(3, 1)(1)^2 (10x^2)^1 + C(3, 2)(1)^1 (10x^2)^2 + C(3, 3)(1)^0 (10x^2)^3

Expanding and simplifying each term, we get:

= 1 + 3(10x^2) + 3(10x^2)^2 + (10x^2)^3

= 1 + 30x^2 + 300x^4 + 1000x^6

Here, the first four terms of the binomial series for the given function (1+10x²)^3 are

1 + 3(10x^2) + 3(10x^2)^2 + (10x^2)^3= 1 + 30x^2 + 300x^4 + 1000x^6

∴ The first four terms of the binomial series for the given function (1+10x²)^3 are 1 + 30x^2 + 300x^4 + 1000x^6.

The polar coordinates (r, θ) can be converted to Cartesian coordinates (x, y) using the relations:

x = r cos θ, y = r sin θThe slope of a polar curve at a given point can be found using the following formula:

dy/dx = (dy/dθ) / (dx/dθ)

where dy/dθ and dx/dθ are the first derivatives of y and x with respect to θ, respectively.

Here, r = 4 and θ = 0.

Using the above relations,

x = r cos θ = 4 cos 0 = 4, y = r sin θ = 4 sin 0 = 0

Differentiating both equations with respect to θ, we get:

dx/dθ = -4 sin θ, dy/dθ = 4 cos θ

Substituting the given values,

dy/dx = (dy/dθ) / (dx/dθ)

= [4 cos θ] / [-4 sin θ]

= -tan θ

The function f(x) = -2x^3 + 33x^2 - 180x + 11 exhibits a local minimum at x = 9 with a value of -218 and a local maximum at x = 3 with a value of 131.

The given function is a cubic polynomial with negative leading coefficient (-2), indicating that it opens downwards. To find the local minimum and local maximum, we need to locate the critical points, where the derivative of the function equals zero. Taking the derivative of f(x), we get f'(x) = -6x^2 + 66x - 180. Setting this derivative equal to zero and solving for x, we find two critical points: x = 9 and x = 3. To determine whether these points correspond to a local minimum or maximum, we can analyze the concavity of the function by examining the second derivative.

Taking the derivative of f'(x), we get f''(x) = -12x + 66. Evaluating this second derivative at x = 9 and x = 3, we find that f''(9) = -42 and f''(3) = 18. Since f''(9) is negative, it indicates a concave-down shape, confirming that x = 9 is a local minimum. Similarly, since f''(3) is positive, it indicates a concave-up shape, confirming that x = 3 is a local maximum. Evaluating the function at these points, we find that f(9) = -218 and f(3) = 131, representing the values of the local minimum and local maximum, respectively.
