day percent change in the height of the sunflower?

the maximum value of |cos(c)| is 1, we have:

|x - a| ≤ 0.006

This means that the values of x for which the function f(x) = sin(x) can be replaced by the Taylor polynomial f(x) = sin(xm) with an error less than or equal to 0.006 are within a distance of 0.006 from the center point a.

To determine the values of x for which the function f(x) = sin(x) can be replaced by the Taylor polynomial f(x) = sin(xm) with an error less than or equal to 0.006, we need to use Taylor's theorem with the Lagrange remainder.

The Lagrange remainder for the nth degree Taylor polynomial is given by:

Rn(x) = (f⁽ⁿ⁺¹⁾(c))/(n+1)! * (x - a)⁽ⁿ⁺¹⁾

where f⁽ⁿ⁺¹⁾(c) represents the (n+1)th derivative of f evaluated at some point c between a and x.

In this case, we want the error to be less than or equal to 0.006, so we set up the inequality:

|(f⁽ⁿ⁺¹⁾(c))/(n+1)! * (x - a)⁽ⁿ⁺¹⁾| ≤ 0.006

Since f(x) = sin(x), we know that the derivatives of sin(x) have a repeating pattern:

f'(x) = cos(x)f''(x) = -sin(x)

f'''(x) = -cos(x)f''''(x) = sin(x)

...

The derivatives alternate between sin(x) and -cos(x), so we can determine the (n+1)th derivative based on the value of n.

For the Taylor polynomial f(x) = sin(xm), we have m = 1, so we only need to consider the first derivative.

The first derivative of f(x) = sin(x) is f'(x) = cos(x).

To find the maximum value of |f'(x)| on the interval [a, x], we look for critical points where f'(x) = 0.

n is an integer.

In this case, we want the error to be less than or equal to 0.006, so we solve the inequality for x:

|(f'(c))/(1!) * (x - a)¹| ≤ 0.006

|cos(c) * (x - a)| ≤ 0.006

The analogous true statement about any 3x2 matrix is (a): Any full rank 3x2 matrix takes a circle in a plane in R3 to an ellipse in R2.

In general, a full rank matrix maps a geometric shape to another shape of lower dimension. In the case of a full rank 2x2 matrix, it maps the unit circle in R2 to an ellipse in R2. Similarly, a full rank 2x3 matrix maps the unit sphere in R3 to an ellipse in R2.

For a full rank 3x2 matrix, it maps a circle in a plane in R3 to an ellipse in R2. This means that the matrix transformation will deform the circular shape into an elliptical shape, but it will still lie within a plane in R3. The number of rows in the matrix determines the dimension of the input space, while the number of columns determines the dimension of the output space.

It's important to note that option (b) suggests an ellipsoid in R3, but this is not the case for a 3x2 matrix. The transformation does not change the dimensionality of the output space. Similarly, options (c) and (d) are not accurate descriptions of the transformation performed by a 3x2 matrix.

The first-order partial derivatives of f(x, y) are ∂f/∂x = 12x^2y^2 - 6x + 5y^2 and ∂f/∂y = 8x^3y - 6xy + 10xy^2. The second-order partial derivatives are ∂²f/∂x² = 24xy^2 - 6, ∂²f/∂y² = 8x^3 + 20xy, and ∂²f/∂x∂y = 24x^2y - 6x + 20y^2.

The first-order partial derivatives of the function f(x, y) = 4x^3y^2 – 3x^2 + 5xy^2 can be calculated as follows:

∂f/∂x = 12x^2y^2 - 6x + 5y^2

∂f/∂y = 8x^3y - 6xy + 10xy^2

To find the second-order partial derivatives, we differentiate the first-order partial derivatives with respect to x and y:

∂²f/∂x² = 24xy^2 - 6

∂²f/∂y² = 8x^3 + 20xy

∂²f/∂x∂y = 24x^2y - 6x + 20y^2

By applying the Mixed Partial Derivative Theorem, we can check if the mixed partial derivatives are equal:

∂²f/∂x∂y = 24x^2y - 6x + 20y^2

∂²f/∂y∂x = 24x^2y - 6x + 20y^2

Since the mixed partial derivatives ∂²f/∂x∂y and ∂²f/∂y∂x are equal, we can conclude that fxy = fyx for this function.

To determine the convergence or divergence of the series Σ 53n+1 (2n + 16)(n + 3)! from n = 0, we can analyze the behavior of the general term of the series and apply convergence tests.

The general term of the series is given by a_n = 53n+1 (2n + 16)(n + 3)!.

To determine the convergence or divergence of the series, we can consider the behavior of the general term as n approaches infinity.

Let's examine the growth rate of the general term. As n increases, the term 53n+1 grows exponentially, while (2n + 16)(n + 3)! grows polynomially. The exponential growth of 53n+1 will dominate the polynomial growth of (2n + 16)(n + 3)!. As a result, the general term a_n will approach infinity as n goes to infinity. Since the general term does not tend to zero, the series does not converge. Instead, it diverges to positive infinity. Therefore, the given series Σ 53n+1 (2n + 16)(n + 3)! from n = 0 is divergent.

In the original recipe, for every 1 1/2 cups of yogurt, Paul uses 1/2 cup of strawberries.

If Paul increases the recipe to include 2 cups of yogurt, we can find the corresponding amount of strawberries by setting up a proportion.

Let's set up the proportion:

(1 1/2 cups of yogurt) / (1/2 cup of strawberries) = (2 cups of yogurt) / (x cups of strawberries)

To solve for x, we can cross-multiply:

(1 1/2) * (x) = (2) * (1/2)

(3/2) * (x) = 1

Multiplying both sides by the reciprocal of 3/2 (which is 2/3):

(2/3) * (3/2) * (x) = (2/3) * (1)

x = 2/3

Therefore, Paul will need 2/3 cup of strawberries when he increases the recipe to include 2 cups of yogurt.

The first series, 1 + 1/3 + 1/6 + 1/9 + ..., is a convergent series with a sum of approximately 1.977.

To determine whether the series is convergent or divergent, we can apply the limit comparison test. Let's consider the series 1 + 1/3 + 1/6 + 1/9 + ... as the given series (S) and the series 1 + 1/2 + 1/3 + 1/4 + ... as the comparison series (T).

We can observe that the terms of the given series are always less than or equal to the terms of the comparison series. Therefore, we can conclude that if the comparison series converges, the given series will also converge. The comparison series, the harmonic series, is known to be a divergent series.

Using the limit comparison test, we can calculate the limit of the ratio of the terms of the given series (S) to the terms of the comparison series (T) as n approaches infinity:

lim (n→∞) (1/n) / (1/n) = 1

Since the limit is a finite positive value, we can conclude that if the comparison series (T) diverges, the given series (S) will also diverge. Therefore, given series 1 + 1/3 + 1/6 + 1/9 + ... is a convergent series.

To find the sum of the series, we can use the formula for sum of an infinite geometric series:

Sum = a / (1 - r)

In this case, first term (a) is 1, and the common ratio (r) is 1/3. Substituting values into formula, we get:

Sum = 1 / (1 - 1/3) = 1 / (2/3) = 3/2 ≈ 1.977

Therefore, sum of the series 1 + 1/3 + 1/6 + 1/9 + ... is approximately 1.977.

L(c) = ∫[a,b] √(1 + (f'(x))^2) dx

In this case, f(x) = x^2, so we can find f'(x) as:

f'(x) = 2x

By finding the critical points, evaluating the function at these points, and analyzing the concavity and sign changes, we can determine the local extrema and inflection points. Absolute extrema are found by comparing the function values at the endpoints of the interval.

To find the local extrema, we first find the derivative of f(x) to locate the critical points. By setting the derivative equal to zero and solving for x, we can find these points. Next, we evaluate the function at these critical points and determine whether they correspond to local maxima or minima by analyzing the sign changes around the points.

To find the absolute extrema, we evaluate the function at the endpoints of the given interval, [-1, 4]. The highest and lowest function values at these endpoints will be the absolute maximum and minimum, respectively.

To find the points of inflection, we need to find the second derivative of f(x) and analyze the sign changes of the second derivative.

To see how the coefficients Cn are related by the equation C+2 = C+1 + Cn, we need to first rewrite the given differential equation in terms of the coefficients Cn. We can use the power series expansion of y to do this:

y = C0 + C1x + C2x^2 + C3x^3 + ...

Taking the derivative of y with respect to x, we get:

y' = C1 + 2C2x + 3C3x^2 + ...

Taking the second derivative of y with respect to x, we get:

y'' = 2C2 + 6C3x + ...

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

(C0 + C1x + C2x^2 + C3x^3 + ...) + (4x + 1)(C0 + C1x + C2x^2 + C3x^3 + ...) - 2(C0 + C1x + C2x^2 + C3x^3 + ...) = 0

Simplifying this expression using the coefficients Cn, we get:

(C0 - 2C0) + (C1 + 4C0 - 2C1) x + (C2 + 4C1 - 2C2 + 6C0) x^2 + (C3 + 4C2 - 2C3 + 6C1) x^3 + ... = 0

Setting the coefficients of each power of x to 0, we get a set of equations:

C0 - 2C0 = 0

C1 + 4C0 - 2C1 = 0

C2 + 4C1 - 2C2 + 6C0 = 0

C3 + 4C2 - 2C3 + 6C1 = 0...

Simplifying these equations, we get:

-C0 = 0

2C1 = 4C0

2C2 = 2C1 - 4C0

2C3 = 2C2 - 6C1...

From the second equation, we have:

C1 = 2C0

Substituting this into the third equation, we get:

2C2 = 2C0 - 4C0 = -2C0

Dividing by 2, we get:

C2 = -C0

Substituting this into the fourth equation, we get:

2C3 = -2C0 - 6(2C0) = -14C0

Dividing by 2, we get:

C3 = -7C0

To find the cross product between vectors u and v, denoted as uxv, you can use the formula:

uxv = |u| * |v| * sin(θ) * n

where |u| and |v| are the magnitudes of vectors u and v, θ is the angle between u and v, and n is a unit vector perpendicular to both u and v.

First, let's calculate the magnitudes of vectors u and v:

|u| = [tex]\sqrt{(-7)^2 + (-4)^2 + (-3)^2}[/tex] = [tex]\sqrt{49 + 16 + 9}[/tex] = [tex]\sqrt{74}[/tex]

|v| = [tex]\sqrt{(5)^2 + (5)^2 + (3)^2}[/tex] = [tex]\sqrt{25 + 25 + 9}[/tex] = [tex]\sqrt{59}[/tex]

Next, let's calculate the angle θ between u and v using the dot product:

u · v = |u| * |v| * cos(θ)

(-7)(5) + (-4)(5) + (-3)(3) = [tex]\sqrt{74}[/tex] * [tex]\sqrt{59}[/tex] * cos(θ)

-35 - 20 - 9 = [tex]\sqrt{(74 * 59)}[/tex] * cos(θ)

-64 = [tex]\sqrt{(74 * 59)}[/tex] * cos(θ)

cos(θ) = -64 / [tex]\sqrt{(74 * 59)}[/tex]

Now, we can find the sin(θ) using the trigonometric identity sin²(θ) + cos²(θ) = 1:

sin²(θ) = 1 - cos²(θ)

sin²(θ) = 1 - (-64 / [tex]\sqrt{(74 * 59)}[/tex])²

sin(θ) = sqrt(1 - (-64 / [tex]\sqrt{(74 * 59)}[/tex])²)

sin(θ) ≈ 0.9882

Finally, we can calculate the cross product magnitude |uxv|:

|uxv| = |u| * |v| * sin(θ)

|uxv| = [tex]\sqrt{74}[/tex] * [tex]\sqrt{59}[/tex] * 0.9882

|uxv| ≈ 48.619

Therefore, the length of uxv is approximately 48.619.

Minutes before the team's arrival. We can use Newton's law of cooling to solve the given problem. According to this law, the rate at which a body cools is proportional to the difference between the temperature of the body and the temperature of the surrounding air.

Mathematically, this is given as:

[tex]$$\frac{d T}{d t}=-k(T-T_{0})$$[/tex] where T is the temperature of the body, T0 is the temperature of the surrounding air, k is a constant, and t is time. Let us solve the differential equation.

[tex]$$dT/dt=-k(T-T_{0})$$$$\Rightarrow \frac{dT}{T-T_{0}}=-kdt$$[/tex]

Integrating both sides, we get:

We can determine the value of D using the given data.

At t = 0, T = 37°C and T0 = 18°C.

Therefore,[tex]$$D=T-T_{0}=37-18=19$$[/tex]

Also, at t = 10 minutes, T = 21°C.

Therefore[tex],$$T-T_{0}=19e^{10k}=21-18=3$$$$\Rightarrow e^{10k}=\frac{3}{19}$$$$\Rightarrow k=\frac{1}{10}\ln\left(\frac{3}{19}\right)$$[/tex]

Let us solve for t when T = 25°C. [tex]$$T-T_{0}=19\left(\frac{3}{19}\right)^{\frac{1}{10}t}=25-18=7$$$$\Rightarrow \left(\frac{3}{19}\right)^{\frac{1}{10}t}=\frac{7}{19}$$$$\Rightarrow t=\frac{10}{\ln(3/19)}\ln(7/19)\approx\boxed{41 \text{ minutes}}$$[/tex]

Let's start by calculating the partial derivatives of f(x, y) with respect to x and y:

∂f/∂x = 2x + 2y - 1   ...(1)

∂f/∂y = 2x + 6y       ...(2)

Setting both partial derivatives equal to zero and solving the resulting system of equations will give us the critical point(s):

-6y + 2y - 1 = 0

-4y - 1 = 0

-4y = 1

y = -1/4           ...(6)

Step-by-step explanation:

The length of cross product u x v is 15. The length of v x u is 15. The direction of u x v is positive k-direction. The direction of v x u is negative k-direction.

To find the length and direction of the cross product u x v and v x u, where u = 3i and v = 5j, we can use the properties of the cross product.

The cross product of two vectors is given by the formula:

[tex]u \times v = (u_2v_3 - u_3v_2)i + (u_3v_1 - u_1v_3)j + (u_1v_2 - u_2v_1)k[/tex]

Substituting the given values:

u x v = (0 - 0)i + (0 - 0)j + (3 * 5 - 0)k

     = 15k

Therefore, the cross product u x v is a vector with magnitude 15 and points in the positive k-direction.

To find the length of u x v, we take the magnitude:

|u x v| = √(0² + 0² + 15²)

       = √225

       = 15

So, the length of u x v is 15.

Now, let's find the cross product v x u:

v x u = (0 - 0)i + (0 - 0)j + (0 - 3 * 5)k

     = -15k

The cross product v x u is a vector with magnitude 15 and points in the negative k-direction.

Therefore, the length of v x u is 15.

The series  ∑[n=1 to ∞] 2 (-1)ⁿ / ln(n) is convergent.

To apply the Alternating Series Test to the series ∑[n=1 to ∞] 2 (-1)ⁿ / ln(n), we need to check two conditions:

The terms bn = 1 / ln(n) are positive and decreasing for n > 3.

The limit of bn as n approaches infinity is 0.

The terms bn = 1 / ln(n) are positive because ln(n) is always positive for n > 1. Additionally, for n > 3, ln(n) is a strictly increasing function, so 1 / ln(n) is decreasing.

Taking the limit as n approaches infinity:

lim (n → ∞) 1 / ln(n) = 0.

Since both conditions of the Alternating Series Test are satisfied, the series ∑[n=1 to ∞] 2 (-1)ⁿ / ln(n) is convergent.

Therefore, the series is convergent according to the Alternating Series Test.

We must compute the partial derivatives of I with respect to R and V and use them to construct the equation of the plane in order to get the equation of the tangent plane to the surface at R = 3 and V = 12.

Find the partial derivative first (frac partial I frac partial R):

Fractal partial I and partial R are equal to fractal partial R (I(R, V)).

The next step is to calculate the partial derivative (fracpartial Ipartial V): [fracpartial Ipartial V = fracpartialpartial V(I(R, V))]

Now, at the values of (R3 = ) and (V = 12), we evaluate these partial derivatives:

The intersection of the given line 7 and the plane π. 1:ř=(4,-1,4)+t(5,-2,3) π: 2x+5y+z+2=0 4 is a single point.

To find the intersection of the line and the plane, we need to determine the values of t that satisfy both the equation of the line and the equation of the plane. The equation of the line is given as r = (4, -1, 4) + t(5, -2, 3), where r represents a point on the line and t is a parameter. The equation of the plane is 2x + 5y + z + 2 = 0.

To find the intersection, we substitute the values of x, y, and z from the equation of the line into the equation of the plane. This gives us the following expression: 2(4 + 5t) + 5(-1 - 2t) + (4 + 3t) + 2 = 0. Simplifying this equation yields 18t - 9 = 0, which gives us t = 1/2.

Substituting t = 1/2 back into the equation of the line gives us the point of intersection: r = (4, -1, 4) + (1/2)(5, -2, 3) = (4, -1, 4) + (5/2, -1, 3/2) = (13/2, -3/2, 11/2).

Therefore, the intersection of the line and the plane is a single point located at (13/2, -3/2, 11/2).

The equivalent measurement of angle [tex]0[/tex] in degrees is [tex]\(\frac{7x \times 180}{6\pi}\)[/tex] degrees.

To find the equivalent measurement of angle [tex]0[/tex] in degrees, we can use the conversion factor which states that there are [tex]180[/tex] degrees in a complete revolution or a circle.

Since angle [tex]0[/tex] is measured in radians, we can set up the equation as:

[tex]\(\frac{7x}{6} \text{ radians} = \text{ degrees}\)[/tex]

To begin with, so as to convert radians to degrees, we can multiply the radian measurement by [tex]\(\frac{180}{\pi}\) (since there are \(180/\pi\)[/tex] degrees in one radian).

Thus, the equivalent measurement of angle [tex]0[/tex] in degrees is written below:

[tex]\(\frac{7x}{6} \times \frac{180}{\pi} \text{ degrees}\)[/tex]

As of the step following it, simplifying the equation written further, we can solve it as follows:

[tex]\(= \frac{7x \times 180}{6\pi} \text{ degrees}\)[/tex]

So, the equivalent measurement of angle 0 in degrees is [tex]\(\frac{7x \times 180}{6\pi}\)[/tex] degrees.

The interval(s) on which the given function f(x) = p2x - 6x is increasing is (3/2, ∞).

The given function is f(x) = p2x - 6x.

A function in mathematics is a relationship between two sets, usually referred to as the domain and the codomain. Each element from the domain set is paired with a distinct member from the codomain set. An input-output mapping is used to represent functions, with the input values serving as the arguments or independent variables and the output values serving as the function values or dependent variables.

We have to find the interval(s) on which the function is increasing. To do this, we can use the first derivative test.

Let's find the first derivative of the function first:f'(x) = 2px - 6

Now we have to find the intervals on which f'(x) > 0 for the function to be increasing.

2px - 6 > 0 (since f'(x) > 0)2px > 6p > 3

From this, we can say that the function is increasing for x > 3/2 or the interval (3/2, ∞). Hence, the interval(s) on which the given function f(x) = p2x - 6x is increasing is (3/2, ∞).

If y = V1 +7 1. = 1 + r' 2. x=re', y = 1 + sin, dy/dr =  √(1-(y-1)²)/x

1. To find dy/dr for y = √(1+7r), we can use the chain rule.

dy/dr = (dy/d(1+7r)) * (d(1+7r)/dr)

The derivative of √(1+7r) with respect to (1+7r) is 1/2√(1+7r).

The derivative of (1+7r) with respect to r is simply 7.

So, putting it all together:

dy/dr = (1/2√(1+7r)) x 7

Simplifying, we get:

dy/dr = 7/2√(1+7r)

2. To find dy/dr for x = re and y = 1+sinθ, we can use the chain rule again.

dx/dr = e

dy/dθ = cosθ

Using the chain rule:

dy/dr = (dy/dθ) * (dθ/dr)

dθ/dr can be found by taking the derivative of x = re with respect to r:

dx/dr = e

dx/de = r

d(e x r)/dr = e

dθ/dr = 1/e

Putting it all together:

dy/dr = cosθ x (1/e)

Since x = re and y = 1+sinθ, we can substitute sinθ = y-1 and r = x/e to get:

dy/dr = cosθ x (1/e) = cos(arcsin(y-1)) x (1/x) = √(1-(y-1)²)/x

So, dy/dr = √(1-(y-1)²)/x

60.8 is less than 70 or 80, we can eliminate answer choices (c) and (d) as possible answers.

To solve this problem, we need to use the formula for standard deviation:
z = (x - μ) / σ

where z is the z-score, x is the raw score, μ is the mean, and σ is the standard deviation.

In this case, we know that the mean score is 82, and your exam score is 2.12 standard deviations below the mean. So we can set up the equation:
z = (x - 82) / σ = -2.12

Now we need to find the possible values of x (your exam score) that satisfy this equation. We can rearrange the equation to solve for x:
x = z * σ + μ

Plugging in the values we know, we get:
x = -2.12 * σ + 82

We don't know the value of σ, so we can't solve for x exactly. But we can use some logic to eliminate some of the answer choices.

Since your exam score is below the mean, we know that x < 82. That means we can eliminate answer choices (a) and (b), since they are both above 82.

To eliminate answer choices (c) or (d), we need to know whether 2.12 standard deviations below the mean is less than or greater than the value of σ.

If σ is relatively small, then a score that is 2.12 standard deviations below the mean will be much lower than 70 or 80. But if σ is relatively large, then a score that is 2.12 standard deviations below the mean could be closer to 70 or 80.

Unfortunately, we don't know the value of σ, so we can't say for sure whether (c) or (d) is a possible answer. However, we can make an educated guess based on the range of possible values for σ.

Since the standard deviation of exam scores is typically in the range of 10-20 points, we can assume that σ is at least 10.

With that assumption, we can calculate the minimum possible value of x:
x = -2.12 * 10 + 82 = 60.8

Since 60.8 is less than 70 or 80, we can eliminate answer choices (c) and (d) as possible answers.

The correct choice is OB: The limit does not exist. A limit is a fundamental concept in calculus that describes the behavior of a function as the input approaches a certain value.

To find the limit of the given expression using L'Hôpital's rule, we differentiate the numerator and denominator until we reach a determinate form. Let's apply L'Hôpital's rule to the limit:

lim (3x^2 - 6x + 1)/(5x^2 - 3x + 1) as x approaches infinity.

Taking the derivatives of the numerator and denominator:

lim (6x - 6)/(10x - 3).

Now, we can evaluate the limit by plugging in x = ∞:

lim (6∞ - 6)/(10∞ - 3) = (∞ - 6)/(∞ - 3).

Since both the numerator and denominator approach infinity, we have an indeterminate form of (∞ - 6)/(∞ - 3). In this case, we cannot determine the limit using L'Hôpital's rule.

The composition (f∘g)(x) is given by (f∘g)(x) = f(g(x)) = f(6x - 1) = 3(6x - 1) + 4 = 18x - 3 + 4 = 18x + 1. The domain of (f∘g)(x) is the set of all real numbers since there are no restrictions on x for this composition.

To find the composition (f∘g)(x), we substitute the expression for g(x) into f(x) and simplify the resulting expression. We have f(g(x)) = f(6x - 1) = 3(6x - 1) + 4 = 18x - 3 + 4 = 18x + 1. Therefore, the composition (f∘g)(x) simplifies to 18x + 1.

The domain of a composition is determined by the domain of the inner function that is being composed with the outer function. In this case, both f(x) = 3x + 4 and g(x) = 6x - 1 are defined for all real numbers, so there are no restrictions on the domain of (f∘g)(x). Therefore, the domain of (f∘g)(x) is the set of all real numbers.

For the composition (g∘1)(x), we substitute 1 into g(x) and simplify the expression. We have (g∘1)(x) = g(1) = 6(1) - 1 = 5. Therefore, (g∘1)(x) simplifies to 5.

Similarly, the domain of (g∘x) is the set of all real numbers since there are no restrictions on x for the composition (g∘x).

The evaluated integral is 55(z + 1) (x² - 1) ln(x² - 1) - 55(z + 1) (x² - 1) + C, where C is the constant of integration.

We have,

To evaluate the integral ∫ 110(z + 1) ln(x² - 1) dx, we will follow the integration rules step by step.

However, it seems there is a typo in the integral expression, as the absolute value notation "|" is not properly placed.

For now, I will assume that the absolute value notation is not necessary for the integral.

Let's proceed with the evaluation:

∫ 110(z + 1) ln(x² - 1) dx

To integrate this, we can apply the method of substitution.

Let's set u = x² - 1, then du = 2x dx.

Substituting these values, we have:

∫ 110(z + 1) ln(u) (1/2) du

Now, we can simplify and integrate:

(1/2) ∫ 110(z + 1) ln(u) du

To integrate ln(u), we use integration by parts.

Let's set dv = ln(u) du, then v = u ln(u) - ∫ (u) (1/u) du.

Simplifying the integral further:

(1/2) [110(z + 1) (u ln(u) - ∫ (u) (1/u) du)]

The term ∫ (u) (1/u) du simplifies to ∫ du, which is simply u.

(1/2) [110(z + 1) (u ln(u) - u)]

Substituting back u = x^2 - 1:

(1/2) [110(z + 1) ((x^2 - 1) ln(x² - 1) - (x² - 1))]

Now, we can perform the final integration:

(1/2) [110(z + 1) (x² - 1) ln(x² - 1) - 110(z + 1) (x² - 1)] + C

Simplifying further:

55(z + 1) (x^2 - 1) ln(x² - 1) - 55(z + 1) (x² - 1) + C

Therefore,

The evaluated integral is 55(z + 1) (x² - 1) ln(x² - 1) - 55(z + 1) (x² - 1) + C, where C is the constant of integration.

The summary of the given information includes developing a 98% confidence interval for the population mean savings amount, determining the range of pages for 99.7% of prints from a print cartridge, estimating the range of savings amounts for 99.7% of customers, and evaluating the reasonableness of stating that the average customer saves $900.

a) To develop a 98% confidence interval for the population mean savings amount, we can use the given data set. We'll calculate the sample mean and standard deviation and then use the t-distribution since the sample size is small (n < 30).

Given data: $649, $867, $961, $764, $958, $1,054, $1,166, $652, $1,125, $1,254, $649, $568, $667, $1,152, $641, $856, $966, $783, $859, $985, $762, $1,159.

Sample mean (x): Calculate the sum of all values and divide it by the sample size (n).

Sample standard deviation (s): Calculate the square root of the sum of squared differences between each value and the sample mean, divided by (n-1).

Once we have x and s, we can calculate the margin of error (ME) using the t-distribution with (n-1) degrees of freedom at a 98% confidence level.

98% confidence interval: (x - ME, x + ME)

b) To determine the range of pages that will include 99.7% of all prints from a print cartridge, we need to assume that the distribution of the print page counts follows a normal distribution. We can then calculate the range using the mean and standard deviation.

Given the mean and standard deviation of the print page counts, we can use the empirical rule or the three-sigma rule. The range will be within three standard deviations of the mean.

c) To determine the range of savings amounts that will include 99.7% of all customers, we need to assume that the distribution of savings amounts follows a normal distribution. Similar to part b, we'll use the mean and standard deviation to calculate the range within three standard deviations of the mean.

d) To determine if it is reasonable to state that the average customer saves $900, we can compare the calculated confidence interval (from part a) with the value of $900. If $900 falls within the confidence interval, it suggests that it is reasonable to state that the average customer saves $900. If $900 falls outside the confidence interval, it would not be reasonable to make that claim.
