Therefore, the value of k is 3 if  the area of the region R is 36.

To find the value of k, we need to find the bounds of the integral that will give us the area of region R. Since R is in the fourth quadrant and is enclosed by the x-axis and the curve y=x^(2)-2kx, we need to find the x-intercepts of the curve:

x^(2)-2kx=0

x(x-2k)=0

x=0 or x=2k

Since R is in the fourth quadrant, we only need to consider the x-intercept x=2k. Therefore, the bounds of the integral are from x=0 to x=2k.

The area of region R can be found using the following integral:

A = ∫[0, 2k] (x^2 - 2kx) dx

= [x^3/3 - kx^2] from 0 to 2k

= (8k^3)/3 - 4k^3

= (4k^3)/3

Since we are given that the area of region R is 36, we can set up the following equation:

(4k^3)/3 = 36

Simplifying, we get:

k^3 = 27

Taking the cube root of both sides, we get:

k = 3

Assuming that the data is normally distributed, approximately 95.44 percent of customers are willing to pay between $1.30 and $1.70 for a pint of frozen yogurt

Find the area under the normal curve between $1.30 and $1.70. To do this, we can use the z-score formula to standardize these values and then use a table of the standard normal distribution to find the area.

The z-score for a value x is given by the formula:

z = (x - mean) / standard deviation

Plugging in the values given in the question, we get:

z(1.30) = (1.30 - 1.50) / 0.10 = -2

z(1.70) = (1.70 - 1.50) / 0.10 = 2

This means that the area under the curve between $1.30 and $1.70 is the area under the curve between -2 and 2. If we look up these values in a table of the standard normal distribution, we find that they correspond to approximately 2.28% and 97.72%, respectively. Therefore, the area under the curve between these two values is approximately 97.72% - 2.28% = 95.44%.

Hence, approximately 95.44% of customers are willing to pay between $1.30 and $1.70 for a pint of frozen yogurt.

Evaluating the definite integral. Use a graphing utility\(##\int_0^4x\sin 2x\,dx\approx0.121##.\)

Let us evaluate the definite integral below by integrating by parts and then use a graphing utility to verify the result\(\[\int_0^4x\sin 2x\,dx\]\) Integration by parts is the method we are going to use to evaluate this integral.\(\[\int uv'\,dx=u\int v\,dx-\int u'v\,dx\]\)   If we let \($u=x$ and $v'=\sin 2x$\) , then \($du=dx$ and $v=-\frac12 \cos 2x$,\[\int x\sin 2x\,dx=-\frac{x}{2}\cos 2x+\frac14\int \cos 2x\,dx\],\)

Applying integration by substitution, \($u=\sin 2x$ and $du=2\cos 2x\,dx$\) , we have\(\[\int x\sin 2x\,dx=-\frac{x}{2}\cos 2x+\frac{1}{8}\sin 2x+C\]\) where \($C$\) is a constant of integration.

To evaluate the definite integral, we substitute the limits of integration to obtain\(\[\begin{aligned}\int_0^4x\sin 2x\,dx&=-\frac{4}{2}\cos 8+\frac{1}{8}\sin 8+\frac{0}{2}\cos 0-\frac18\sin 0\\&=\frac18-\frac{2}{\sqrt{2}}\cos 8\approx0.121\end{aligned}\].\)

Parts (a) and (b) are functions since they pass the vertical line test.

Part (c) is not a function. It fails the vertical line test since it is possible to pass a single vertical line through more than one point on the curve. In other words, some x input leads to more than one y output. A function can only have one output for any given input.

--------------------

The domain of part (a) is the set of all real numbers. We can plug in any value for x. The domain in interval notation is (-infinity, infinity) as this describes the entire real number line. The domain is the set of all possible inputs.

The range for part (a) is the set of y values such that \(1 \le y \le 3\) because the lowest points are when y = 1 and the highest points are when y = 3. The range is the set of all possible outputs. The range in interval notation is [1, 3]. Note the use of square brackets to include the endpoint.

----------------------

The domain for part (b) is also the set of real numbers. The reasoning is the same as part (a).

The range of part (b) is \(y \ge 0\) since y = 0 is the lowest y possible output, and there is no largest output y value. The range in interval notation is [0, infinity).

----------------------

The domain of part (c) is different from the others. On this graph, the left-most point is when x = -2, so the domain is the set of real x values such that \(x \ge -2\) which translates to [-2, infinity) in interval notation.

The range of part (c) is the set of all real numbers. Any y value is a possible output because the parabola stretches upward and downward forever.

Answer:

\(m=\frac{-5}{3}\)

Step-by-step explanation:

We want to find the slope between the points (-2,5) and (1,0).

The slope (m) can be found using the formula \(\frac{y_2-y_1}{x_2-x_1}\), where \((x_1,y_1)\) and \((x_2,y_2)\) are points.

We are already given the values of the points, but let's label their values to avoid any confusion and mistakes.

\(x_1=-2\\y_1=5\\x_2=1\\y_2=0\)

Now, substitute into the formula.

\(m=\frac{y_2-y_1}{x_2-x_1}\)

\(m=\frac{0-5}{1--2}\)

Simplify this to:

\(m=\frac{0-5}{1+2}\)

\(m=\frac{-5}{3}\)

The slope is -5/3.

The dividend in 2018 was $2.95, and it is expected to grow at a rate of 7.4% for the next five years and 2.6% thereafter. With an equity cost of capital of 8.6%, the value per share at the end of 2018 can be calculated.

To calculate the value per share at the end of 2018, we need to discount the expected future dividends using the dividend-discount model. The model assumes that the value of a stock is equal to the present value of all its expected future dividends.

First, we need to calculate the dividends for each year from 2019 to 2023. We start with the dividend in 2018, which was $2.95. We then increase it by 7.4% each year for the next five years:

Dividend in 2019 = $2.95 * (1 + 7.4%) = $3.17

Dividend in 2020 = $3.17 * (1 + 7.4%) = $3.40

Dividend in 2021 = $3.40 * (1 + 7.4%) = $3.65

Dividend in 2022 = $3.65 * (1 + 7.4%) = $3.92

Dividend in 2023 = $3.92 * (1 + 7.4%) = $4.22

After 2023, the dividend is expected to grow at a rate of 2.6% per year. To find the value per share at the end of 2018, we discount the future dividends to their present value using the equity cost of capital of 8.6%.

The present value of the dividends can be calculated as follows:

PV = (D1 / (1 + r)) + (D2 / (1 + r)^2) + ... + (Dn / (1 + r)^n)

where PV is the present value, D1 to Dn are the dividends for each year, r is the equity cost of capital, and n is the number of years.

In this case, n = 5 because we are discounting the dividends for the next five years. Let's calculate the present value:

PV = ($3.17 / (1 + 8.6%)) + ($3.40 / (1 + 8.6%)^2) + ($3.65 / (1 + 8.6%)^3) + ($3.92 / (1 + 8.6%)^4) + ($4.22 / (1 + 8.6%)^5)

PV = $3.17 / 1.086 + $3.40 / 1.086^2 + $3.65 / 1.086^3 + $3.92 / 1.086^4 + $4.22 / 1.086^5

PV ≈ $2.91 + $3.07 + $3.24 + $3.41 + $3.59

PV ≈ $16.22

Therefore, the estimated value per share of Procter and Gamble at the end of 2018 using the dividend-discount model is approximately $16.22.

Answer:

D. 3/9

Step-by-step explanation:

Attached below is a picture with each fraction illustrated.

Answer:

y = -x - 5

Step-by-step explanation:

To find the equation of the line passing through two given points, we can use the point-slope form of a linear equation:

y - y1 = m(x - x1)

Where m is the slope of the line, and (x1, y1) are the coordinates of one of the points on the line.

We first need to find the slope of the line passing through the two given points. We can use the formula:

m = (y2 - y1)/(x2 - x1)

where (x1, y1) = (-8, 3) and (x2, y2) = (-2, -3)

m = (-3 - 3) / (-2 - (-8)) = -6 / 6 = -1

Now, we can use the point-slope form of the equation with one of the given points, say (-8, 3):

y - 3 = -1(x - (-8))

Simplifying:

y - 3 = -x - 8

y = -x - 5

Answer:

(-8, 3) and (-2, -3) is y = -x - 5

Step-by-step explanation:

To find the equation of a line passing through two given points, we can use the point-slope form of a linear equation:

y - y1 = m(x - x1)

Where (x1, y1) are the coordinates of one of the points on the line, and m is the slope of the line.

Given the points (-8, 3) and (-2, -3), we can calculate the slope (m) using the formula:

m = (y2 - y1) / (x2 - x1)

Substituting the coordinates into the formula:

m = (-3 - 3) / (-2 - (-8))

m = (-3 - 3) / (-2 + 8)

m = (-6) / (6)

m = -1

Now that we have the slope (m = -1) and one of the points (x1, y1) = (-8, 3), we can use the point-slope form to write the equation:

y - 3 = -1(x - (-8))

y - 3 = -1(x + 8)

y - 3 = -x - 8

y = -x - 8 + 3

y = -x - 5

Therefore, the equation that represents a line passing through the points (-8, 3) and (-2, -3) is y = -x - 5.

C) 4.0 ft  

Step-by-step explanation:

We will use the Pythagorean theorem to solve this.  It states that the sum of the squares of the legs of a right triangle is equal to the square of the hypotenuse; algebraically,

a²+b² = c²

The height splits the base in two, giving us a leg of 3.  The hypotenuse is 5.  This gives us:

3²+b² = 5²

9+b² = 25

Subtract 9 from each side:

9+b²-9 = 25-9

b² = 16

Take the square root of each side:

√b² = √16 = 4

If {V1, V2} is linearly independent, then {5V1 + 4V2, 6V1 + 5V2} is also linearly independent.

To prove the statement, we assume that {V1, V2} is linearly independent. We need to show that {5V1 + 4V2, 6V1 + 5V2} is also linearly independent.

Suppose there exist scalars a and b, not both zero, such that a(5V1 + 4V2) + b(6V1 + 5V2) = 0. Simplifying, we have (5a + 6b)V1 + (4a + 5b)V2 = 0.

Since {V1, V2} is linearly independent, the only way for the above equation to hold is if 5a + 6b = 0 and 4a + 5b = 0 simultaneously. Solving this system of equations, we find a = b = 0 as the only solution.

Therefore, {5V1 + 4V2, 6V1 + 5V2} is linearly independent, as the only combination of scalars that results in the zero vector is when all scalars are zero. Thus, the statement is proven.
