Albright Motors is expected to pay a year-end dividend of $3 per share \((\(D_1 = \$3.00\))\), followed by a dividend of $5 in 2 years \((\(D_2 = \$5.00\))\). To calculate the present value of these future dividends, we can use the concept of discounting to determine the current value of the expected dividends.

The present value of future dividends can be calculated using the formula:

Present Value = \(\(\frac{{D_1}}{{(1 + r)^1}} + \frac{{D_2}}{{(1 + r)^2}}\)\)

where \(\(D_1\) and \(D_2\)\) are the future dividends and \(\(r\)\) is the required rate of return or discount rate.

In this case, the dividend \(\(D_1\)\) is $3 and the dividend \(\(D_2\)\) is $5. To find the required rate of return \((\(r\))\), we need additional information such as the stock price or market value of Albright Motors' shares. Without that information, we cannot determine the exact value of the required rate of return or calculate the present value of the dividends.

Once the required rate of return is known, we can substitute the values into the formula to calculate the present value of the future dividends. The present value represents the current value of the expected dividends, taking into account the time value of money.

The amount of fencing needed to surround the perimeter of the picnic area of the park is 107 yards. Hence, the second option is the right choice.

In the question, we are informed that the triangle KLM, represents a section of a park set aside for picnic tables. We are also informed that the picnic area will take up approximately 400 square yards of the park.

We are asked for the amount of fencing needed to surround the perimeter of the picnic area of the park.

We know the area of a triangle can be found using the trigonometric area formula, Area = (1/2)ab sin C.

Using this in the given triangle KLM, we get:

Area = (1/2)(KL)(KM)(sin K),

or, 400 = (1/2)(KL)(45)(sin 25°),

or, KL = (400*2)/(45*sin 25°) = 800/(45*0.42262) = 800/19.017822 = 42.0658 ≈ 42 yd.

Thus, we get KL = 42 yards.

Now, the perimeter of the picnic area = the perimeter of the triangle KLM = KL + LM + MK = 42 + 20 + 45 yards = 107 yards.

Thus, the amount of fencing needed to surround the perimeter of the picnic area of the park is 107 yards. Hence, the second option is the right choice.

These are interval for increasing (doesnt include relative max-min)

Step-by-step explanation:

Increasing means when we input the value of x and we get the increase of y-value.

A bit hard to imagine? You can look at the graph instead. The name already says it all, Increasing Graph. The graph keeps rising and rising till the max and that is increasing.

The decreasing is when the graph decreases to minimum. The graph would face down for decreasing.

The amount of error that you will accept in the upper tail of the confidence interval as follows

The amount of error that will accept in the upper tail is = 13.97

Amount of error = margin of error

Margin of error = \(Z\frac{\alpha }{2} \frac{s}{\sqrt{n} }\)

93% = confidence interval =1- \(\alpha\)

=1-.93

=0.07

Hence \(\frac{\alpha }{2}\) =0.035

\(Z\frac{\alpha }{2} or t\frac{\alpha }{2} = 1.81\)

This problem represents two tail test because a two-tailed test is a method in which the critical area of a distribution is two-sided and tests whether a sample is greater or less than a range of values.

And confidence interval are always two tailed.

So margin of error = \(1.81x\frac{1.99}{\sqrt{40} }\)

= 0.57

Upper tail C.I = x + margin of error

=13.4+0.57

=13.97

Lower tail C.I = x - margin of error

= 13.4 - 0.57

=12.83

Hence the answer is, the amount of error that will accept in the upper tail is = 13.97.

a) The magnitude of the line current IL is determined by IL = Vphase / Zline. b) The magnitude of the load's line and phase voltages VLL and V⊙L are both equal to VLL =\(\sqrt3\)* Vphase. c) The real power consumed by the load is \(P = 3 * |IL|^2 *\) Re(Zload), the reactive power is \(Q = 3 * |IL|^2\)* Im(Zload), and the apparent power is \(S = \sqrt{(P^2 + Q^2)}\). d) The power factor of the load is PF = P / S.  e) The real power consumed by the transmission line is Pline = \(3 * |IL|^2 *\) Re(Zline), the reactive power is Qline =\(3 * |IL|^2 *\) Im(Zline), and the apparent power is Sline \(= \sqrt{(Pline^2 + Qline^2)}\). f) The real power consumed by the generator is zero, the reactive power is zero, and the apparent power is Sgen =  \(3 * |IL|^2 *\) * |Vphase|. g) The generator's power factor is zero.

To solve the problem, substitute the given values into the equations and perform the necessary calculations. Drawing the power system diagram will help visualize the connections and values of the generator, transmission line, and load.

a) The magnitude of the line current IL can be calculated using Ohm's Law. Since the generator is Y-connected, the line current is equal to the phase current, which is given by IL = Vphase / Zline, where Vphase is the phase voltage of the generator and Zline is the impedance of the transmission line per phase.

b) The magnitude of the load's line voltage VLL can be calculated as VLL = \(\sqrt3\) * Vphase, where Vphase is the phase voltage of the generator.

Since the load is Δ-connected, the magnitude of the load's phase voltage V⊙L is the same as the line voltage, V⊙L = VLL.

c) The real power consumed by the load can be calculated as P =\(3 * |IL|^2 *\) Re(Zload), where Zload is the impedance of the load per phase.

The reactive power consumed by the load can be calculated as Q =  \(3 * |IL|^2\)* Im(Zload).

The apparent power consumed by the load can be calculated as S = \(\sqrt{P^2 + Q^2}\)

d) The power factor of the load can be calculated as PF = P / S.

e) The real power consumed by the transmission line can be calculated as Pline =  \(3 * |IL|^2\) * Re(Zline), where Zline is the impedance of the transmission line per phase.

The reactive power consumed by the transmission line can be calculated as Qline =  \(3 * |IL|^2\)* Im(Zline).

The apparent power consumed by the transmission line can be calculated as Sline \(= \sqrt{(Pline^2 + Qline^2)}\).

f) Since the generator is ideal, there is no real or reactive power consumed by the generator. Therefore, the real and reactive powers consumed by the generator are both zero. The apparent power consumed by the generator can be calculated as Sgen = \(3 * |IL|^2\)* |Vphase|.

g) The power factor of the generator is also zero, as there is no real power consumed by the generator.

The length of the patio in the drawing, according to the scale of the drawing of 12 cm : 7 m, is 36 cm.

A scale is defined to be the ratio between the size of a given original object and a new object, which is its representation but is either smaller or bigger. It refers to the relative size of an object. Sometimes it is called a scale factor.

We are given a scale of the drawing of 12 cm : 7 m. Also, the actual length of the front patio is 21 m. To find the length of the patio in the drawing, we'll use algebra.

First, we write an equation that contains the scale of the drawing and the ratio of the actual length of the front patio to the length of the patio in the drawing, which is unknown still so we use a variabel x:

12 cm / 7 m = x / 21 m

Note that we're asked to find the length of the patio in the drawing in centimeters, so we'll then need to convert from meters to centimeters. Remember that 1 meter is defined to be equal to 100 centimeters.

12 cm / (7 · 100) = x / (21 · 100)

12 cm / 700 cm = x / 2,100 cm

Finally, let's solve for x.

12 / 700 = x / 2,100

3 / 175 = x / 2,100

6,300 = 175x

175x = 6,300

x = 36

Since x = 36 and it represents the length of the patio in the drawing, it then is equal to 36 centimeters.

Answer:

885.01

Step-by-step explanation:

The value of each variable is:

x = -2

w = 8

r = 4

t = -1

Equating the first elements:

x - 5 = -7

We can solve this equation for x by adding 5 to both sides:

x = -7 + 5

x = -2

Equating the second elements:

9 = w + 1

We can solve this equation for w by subtracting 1 from both sides:

w = 9 - 1

w = 8

Equating the third elements:

4 = 8 - r

We can solve this equation for r by subtracting 8 from both sides:

8 - r = 4

Next, we can subtract 8 from both sides:

-r = 4 - 8

-r = -4

Finally, multiplying both sides by -1 to isolate r:

r = -4 × -1

r = 4

Equating the fourth elements:

t + 2 = 1

We can solve this equation for t by subtracting 2 from both sides:

t = 1 - 2

The expression equivalent to\(-4x^2 + 2x - 5(1 + x)\)  is \(4x^2 + 8x + 5.\)

This expression matches the form \(x^2 + x + c,\) where c = 5.

To simplify the given expression \(-4x^2 + 2x - 5(1 + x)\) and make it equivalent to the expression \(x^2 + x + c,\) where c is a constant term, we need to perform some algebraic operations.

First, let's distribute the -5 to the terms inside the parentheses:

\(-4x^2 + 2x - 5 - 5x\)

Next, we can combine like terms:

\(-4x^2 + (2x - 5x) - 5 - 5x\)

Simplifying further:

\(-4x^2 - 3x - 5 - 5x\)

Now, let's rearrange the terms to match the form \(x^2 + x + c:\)

\(-4x^2 - 3x - 5x - 5\)

To make the leading coefficient positive, we can multiply the entire expression by -1:

\(4x^2 + 3x + 5x + 5\)

Now, we can combine the x-terms:

\(4x^2 + 8x + 5\)

So, the expression equivalent to \(-4x^2 + 2x - 5(1 + x)\) is \(4x^2 + 8x + 5.\)This expression matches the form \(x^2 + x + c,\) where c = 5.

It's important to note that the original expression and the equivalent expression have different coefficients and constants, but they represent the same mathematical relationship.
