y-20 = 0.75(x-4) solve for y
Answers
Answer:
y = 0.75x + 17
Step-by-step explanation:
y - 20 = 0.75(x-4)
y - 20 = 0.75(x) + 0.75(-4)
y - 20 = 0.75x -3
y = 0.75x -3 + 20
y = 0.75x + 17
y - 20 = 0.75(x - 4) |add 20 to both sides
y = 0.75(x - 4) + 20we can simplified equation:
use the distributive property: a(b + c) = ab + ac
y = 0.75x - 0.75 · 4 + 20
y = 0.75x - 3 + 20

(20 points) 5 What should the value of the firm equal if Miller ' 77 is correct? Assume that \( \mathrm{T}_{\mathrm{C}}=40 \% \), \( \mathrm{T}_{\mathrm{dd}}=25 \% \), and \( \mathrm{T}_{\mathrm{ps}}=
Answers
According to Miller's theorem in 1977, the value of the firm should be unaffected by its capital structure or the specific tax rates. Therefore, under Miller's theory, the value of the firm would remain the same regardless of the given tax rates (Tc = 40%, Tpd = 25%, Tps = 30%).
Miller's theorem, also known as the Modigliani-Miller theorem, states that in a perfect capital market with no taxes, bankruptcy costs, or information asymmetry, the value of the firm is determined solely by its underlying cash flows and the riskiness of its investments. The specific tax rates mentioned (Tc = 40%, Tpd = 25%, Tps = 30%) do not impact the firm's value according to Miller's theory.
The theorem implies that any change in the capital structure, such as increasing or decreasing debt levels, would not affect the overall value of the firm. In an efficient market, investors can replicate the firm's cash flows and risk profile through their own choices of leverage and therefore, the firm's value would be unaffected by these factors.
Therefore, under Miller's '77 theory, the value of the firm would be independent of the given tax rates (Tc = 40%, Tpd = 25%, Tps = 30%). The firm's value would solely depend on its expected cash flows and the risk associated with its investments.

What is the ratio of rise to run between the points (-2, 8) and (4, -3)?
Answers
Ratio of rise to run between the points (-2, 8) and (4, -3) = -11/6
To find the ratio of rise to run between two points, we need to calculate the difference in the y-coordinates (rise) and the difference in the x-coordinates (run) between the two points.
Given points:
Point 1: (-2, 8)
Point 2: (4, -3)
Rise = difference in y-coordinates = y2 - y1 = -3 - 8 = -11
Run = difference in x-coordinates = x2 - x1 = 4 - (-2) = 6
Therefore, the ratio of rise to run can be calculated as:
Ratio of rise to run = Rise / Run = -11 / 6
Thus, the ratio of rise to run between the points (-2, 8) and (4, -3) is -11/6.

The local furniture store pays $130 for a dining room table and sells it with a 30% markup. What is the selling price of the dining room table?
Answers
Let the cost of the dining table is 100%
∵ It sells with a 30% markup
→ That means the selling price of the table will be 100% + 30%
∴ The selling price of the table = 130% of the cost price
∵ The cost price of the table = $130
∴ The selling price of the table = 130% x 130
→ Change the percentage to a decimal by divide it by 100
\(\because\frac{130}{100}=1.30\)∴ The selling price of the table = 1.30 x 130 = 169
∴ The selling price of the dining table is $169
Identify a product/service that is currently in the decline stage. Use the Product Lifecycle Concept to explain why you believe the product/service is at that stage .
Describe the strategic options for companies that are competing in a declining market. Provide specific examples too illustrate what these strategic options entail and how they differ .
Answers
One product/service that is currently in the decline stage is DVD rentals. The decline can be attributed to the rapid rise of digital streaming platforms and the decreasing popularity of physical media. Companies competing in a declining market have strategic options such as harvesting and divesting. Harvesting involves maximizing profits from the declining product/service by reducing costs and maintaining a loyal customer base, while divesting involves exiting the market and reallocating resources to more profitable ventures.
DVD rentals are in the decline stage of the product lifecycle due to several factors. The advent of digital streaming platforms like Netflix, Hulu, and Amazon Prime Video has revolutionized the way people consume media. The convenience and vast content libraries offered by these platforms have led to a significant decline in DVD rentals. Moreover, the proliferation of high-speed internet connections and the increasing availability of streaming devices have made it easier for consumers to access digital content.
In a declining market, companies have strategic options to consider. One option is harvesting, which involves maximizing profits from the declining product/service. Companies can achieve this by reducing costs associated with production, distribution, and marketing, as the demand for the product/service diminishes. They may also focus on retaining their loyal customer base by providing incentives, discounts, or exclusive offers. For example, DVD rental companies may lower rental fees, offer bundle deals, or introduce loyalty programs to retain their remaining customers.
Another strategic option is divesting, which involves exiting the declining market altogether. Companies may choose to reallocate their resources to more profitable ventures or invest in emerging technologies or industries. In the case of DVD rentals, companies could divest by shutting down physical rental stores and selling off their DVD inventory. They could then shift their focus to digital streaming services or invest in other areas with growth potential, such as content production or streaming device manufacturing.

26) You have money in an account at 6% interest, compounded monthly. To the nearest year, how long will it take for your money to double?
A) 16 years
B) 7 years
C) 9 years
D) 12 years
Answers
The main answer to the question "How long will it take for your money to double?" is C) 9 years.
Compounded interest refers to the process of earning interest on both the initial amount of money deposited and any previously earned interest. In this case, the money in the account earns a 6% interest rate, compounded monthly. To determine how long it will take for the money to double, we can use the concept of the rule of 72.
The rule of 72 is a simplified formula used to estimate the time it takes for an investment to double at a given interest rate. By dividing 72 by the interest rate, you can approximate the number of years it will take for the initial amount to double.
In this scenario, the interest rate is 6%. By dividing 72 by 6, we get 12. This means that the money will double approximately every 12 years. However, since the question asks for the answer to the nearest year, we need to consider that compounding occurs monthly.
Since interest is compounded monthly, we need to adjust the result by dividing by 12 (the number of months in a year). By doing so, we find that the money will double approximately every 1 year. Therefore, it will take approximately 9 years for the money to double.

A man travels at 42 degrees northwest, and ends up 8.5 miles west of his starting point. How far did he travel?
Answers
Answer:
The man traveled 12.70 miles.
Step-by-step explanation:
We can find the distance traveled by the man knowing:
\(d_{W}\): the distance at the west = 8.5 miles
\(\theta_{NW}\): the northwest angle = 42°
Then by using the following trigonometric identity we have:
\( sin(\theta) = \frac{d_{W}}{d_{NW}} \)
\( d_{NW} = \frac{d_{W}}{sin(\theta)} = \frac{8.5 miles}{sin(42)} = 12.70 miles \)
Therefore, the man traveled 12.70 miles.

\(f(x+h)=(x+h)^2-2(x+h)\)\(f(x+h)=x^2+2xh+h^2-2x-h^{}\)Then we calculate and simplify the coeficient in the first formula

First you need to know that the derivate of a function is equal to the slope (m) of the tangent of this function
And the equation to thist tangent in a specific point will be find using the next formula:
\(y-f(x_0)=m(x-x_0)_{}\)We have to calculate the slope in the point x =4 using the derivate:
\(m=2x-1\)\(m=2(4)-1=7\)In the point x=4
Calculate the value of f(x0) substituting in the function the given point x:
\(f(4)=4^2-2(4)\text{ = }8\)Knowing that we put the value of m and f(x0) in the equation of the tangent:
\(y-8=7(x-4)_{}\)\(y-8=7x-28\)\(y=7x-28+8\)So the equation of the tangent in x= 4 is:\(y=7x-20\)---------------------------------------------------------------------------
The normal line
The slope of the normal line is the opposite of the slope of theu tangent in an espesific point:
\(m_n=-\frac{1}{m_t}\)So in this situation is:
\(m_n=-\frac{1}{7}\)The equation of the normal line is given by the next formula:
\(y-f(x_0)=m_n(x-x_0)_{}\)Replacing the data we obtain:
\(y-8=-\frac{1}{7}(x-4)_{}\)\(y-8=-\frac{1}{7}x+\frac{4}{7}\)So the equation of the normal line is:\(y=-\frac{1}{7}x+\frac{60}{7}\)statistics computed for larger random samples are less variable than the statistic computed for smaller random samples
Answers
Statistics computed for larger random samples tend to be less variable compared to statistics computed for smaller random samples.
This statement is based on the concept of the Central Limit Theorem (CLT) in statistics. According to the CLT, as the sample size increases, the distribution of the sample mean approaches a normal distribution regardless of the shape of the population distribution. This means that the variability of the sample mean decreases as the sample size increases.
The variability of a statistic is commonly measured by its standard deviation or variance. When working with larger random samples, the individual observations have less impact on the overall variability of the statistic. As more data points are included in the sample, the effects of outliers or extreme values tend to diminish, resulting in a more stable and less variable estimate.
In practical terms, this implies that estimates or conclusions based on larger random samples are generally considered more reliable and accurate. Researchers and statisticians often strive to obtain larger sample sizes to reduce the variability of their results and increase the precision of their statistical inferences.
