Answer: 270

Step-by-step explanation: A tip for multiplying a number with any power of 10 is to just "add" a 0 to the end of the number depending on how many 0's there are in the power of 10.

For example, there is one 0 in 10. So I would just add a 0 to the end of 27 to get 270. If I were to multiply 27 by 100, there are two 0's in 100 so it would be 2700. 27 x 1000 would be 27000.

Step-by-step explanation:

The first mistake on the finding on the continuity of the function happened on Step 3, hence option B is correct.

A function f(x) is continuous at x = a if it is defined at x = a, and the lateral limits are equal, that is, if these three conditions are respected:

[tex]\lim_{x \rightarrow a^-} f(x) = \lim_{x \rightarrow a^+} f(x) = f(a)[/tex]

To verify the continuity on this problem, the limit was first found at x = 4. Following the standard procedure, replacing each instance of x by 4, an undetermined value of 0/0 is reached. Thus the correct procedure was undertaken, factoring each polynomial in the numerator and in the denominator, then simplifying the common terms and calculating the limit.

However, to calculate the numeric value of the function at x = 4, the simplification cannot be applied, each instance of 4 needs to be replaced.

Replacing each instance of x by 4, the denominator will be of 0, meaning that the function is not defined at x = 4, hence the first mistake was in Step 3 and option B is correct.

A polynomial of degree 4 in factored form with zeros 1, -4, 0, and 6 is

f(x) = x(x - 1)(x + 4)(x - 6).

Given:

x₁ = 1

x₂ = -4

x₃ = 0

x₄ = 6

Utilize the fact that x - b is a factor of the polynomial if b is a root.

Simply take each zero, modify its sign, and add an x in front of it to obtain the four factors.

The polynomial is,

f(x) = (x - x₁)(x - x₂)(x - x₃)(x - x₄)

f(x) =  (x - 1)(x - (-4))(x - 0)(x - 6)

     = (x - 1)(x + 4(x)(x - 6)

Therefore,a 4 degree polynomial in factored form with zeros 1, -4, 0,and 6 is x(x - 1)(x + 4)(x - 6).

Answer:

  C. It is not proportional. y/x ratios are not equivalent

Step-by-step explanation:

Given a rental charge of $25 for the first hour and $20 for each additional hour, you want to know if the charges are proportional to the time.

In this situation, if the relationship were proportional, the charge per hour (constant of proportionality) would be the same for every hour. Here, the first hour costs more, so the hourly charge is not constant.

Here, we have, for x=hours, y=dollars, ...

  (1, 25)   ⇒   y/x = 25

  (2, 45)   ⇒   y/x = 22.5

  (3, 65)   ⇒   y/x ≈ 21.67

The y/x values are not constant (because the charge per hour is not constant). The relationship is not proportional.

By using the method of interest, principle is 2777.7.

An expense associated with borrowing money or other assets is interest. The principal is the amount borrowed, and the interest is calculated as a percentage of the principal for a specific period of time. The expense of borrowing money is interest. It equates to a fee or additional charge the borrower pays the lender for the loaned amount, and is sometimes stated as a percentage. When you make a payment on a loan with simple interest, the money first goes toward the interest for that month and the rest is applied to the principal. S.I. = P R T, where P = Principal, R = Rate of Interest in% per annum, and T = Time, typically calculated as the number of years, is the formula used to compute simple interest.

Given that,

S.I= PTR

Simple interest= 50

Time= 9/12= 0.75

Rate of interest= 2.4

Principle amount=?

S.I= PTR

50= P x 0.75 x 2.4

50= P x 1.8

P = 50X1.8

P= 2777.7

Therefore, principle is 2777.7

Step-by-step explanation:

The probability mass function for this is given by the table that is attached below.

Probability is defined as the proper fraction which signifies the likelihood of an event to occur.

Total number of possible arrangements of 6 people are 6! = 720

Here X can take value 0, 1, 2, 3, or4.

For the probability function : When X= 0 , it means there is no child between mother and father. Taking mother and father as one , number of possible arrangements of 5 people are 5!.

And mother and father can arranged themselves is 2! ways. So for X=0, possible ways are 5! *2 = 240.

Therefore the require probability at X=0 is given by:

P(X=0) = 240 /720 = 0.3333

For the probability function : When X = 1 , then there is one child between mother and father. Number of ways of selecting one child is C(4,1) = 4.

Mother and father can be arrange themselves in 2 ways so possible number of arrangements are 4 * 2 * 4! = 192

Therefore the require probability at X=1 is given by:

P(X=1) = 192 /720 = 0.2667

For the probability function :When X=2 , then there are two children between mother and father. Number of ways of selecting two children is C(4,2) = 6.

Mother and father can arrange themselves in 2 ways, children between mother and father can arranged themselves in 2 ways so possible number of arrangements are 6 * 2 * 2* 3! = 144

Therefore the require probability at X=2 is given by:

P(X=2) = 144 /720 = 0.2

For the probability function : When X=3 , then there are three children between mother and father. Number of ways of selecting three children is C(4,3) = 4.

Mother and father can arrange themselves in 2 ways, children between mother and father can arranged themselves in 3! ways so possible number of arrangements are 4 * 2 * 3!* 2! = 96

Therefore the require probability at X=3 is given by:

P(X=3) = 96 /720 = 0.1333

For the probability function: When X=4 , then there are 4 children between mother and father. Number of ways of selecting 4 children is C(4,4) = 1.

Mother and father can arranged themselves in 2 ways, children between mother and father can arranged themselves in 4! ways so possible number of arrangements are 1 * 2 * 4! = 48

Therefore the require probability at X=0 is given by:

P(X=4) = 48 /720 = 0.0667

To answer this question, first of all, we need to find the equation for each of the lines on the graph. To do so, we have to identify two points for each line, and then use the two-point form equation (of the line) to find the equation of each line.

Then, we have:

We identify two points: (1, 1) and (2, 2).

Then we have:

Then if we label both points above:

• (1, 1) ---> x1 = 1, y1 = 1

• (2, 2) ---> x2 = 2, y2 = 2

Therefore:

Therefore, the equation of the line for the solid line is y = x.

We can proceed similarly as we did before. Then we have:

The two points are (2, 4) and (4, 8).

Then we can label them as follows:

• (2, 4) ---> x1 = 2, y1 = 4

• (4, 8) ---> x2 = 4, y2 = 8

Therefore, the equation for the dotted line is y = 2x.

We need to remember that when we have the symbols < or > the inequality is represented by a dotted line. Conversely, when it appears additionally an equal sign in the inequality symbol, ≥ or ≤ the line is represented as a solid line.

If we see the graph, we can say that the graph is represented by the following inequalities:

Since if we represent them graphically, we have - using a graphing calculator:

We can observe that the shaded area is the same as the one represented in the graph given in the question.

We can prove that if we take a point in the solution region as follows:

1. For example, we can test the point (-2, 2). Then we have:

Now, using this we can check if the other system of inequalities is equivalent to this:

We can check the following inequalities:

Which is equivalent to the previous one.

In summary, we have that the systems of linear inequalities are the following:

[Third option]

And

[Fourth option]

[The second and the third options are not answers since both have the symbol, ≥, - and it means that we have two solid lines representing the inequality system.]

[In the first option we have that the first inequality represents a solid line, and this is not the case. The dotted line is represented by y > 2x.]

When f(x) > 0, it means that on a graph, the line is above the x-axis.

Out of all the options, only in -2 < x < -1 is the graph above the x-axis.

For the other two intervals, the graph is below the x-axis.

[tex]11.9375\%[/tex] is the cost of equity using the capital asset pricing model if the risk free rate is 4.5%, the beta is 1.75 and the equity risk premium is 4.25%.

In the given question we have to find the cost of equity using the capital asset pricing model if the risk free rate is 4.5%, the beta is 1.75 and the equity risk premium is 4.25%.

Firstly we learn about terms used in this question,

The return needed by either a business or an individual to justify an investment in equity is known as the cost of equity.

The relationship between systemic risk, or the general dangers of investing, and expected return for assets, particularly equities, is described by the Capital Asset Pricing Model.

Since we have to find the cost of equity using the capital asset pricing model. So the formula is

Cost of equity = Risk free rate + Beta * Equity Risk Premium

Risk free rate = 4.5%

Beta = 1.75

Equity Risk Premium = 4.25%

Now putting the value in the formula

Cost of equity [tex]=4.5\%+1.75\times4.25\%[/tex]

Simplifying

Cost of equity [tex]=4.5\%+7.4375\%[/tex]

Cost of equity [tex]=11.9375\%[/tex]

Hence, [tex]11.9375\%[/tex] is the cost of equity using the capital asset pricing model if the risk free rate is 4.5%, the beta is 1.75 and the equity risk premium is 4.25%.
