The correct option regarding the domain and the range of the function is given by:

A. The domain is (-∞, ∞), and the range is (k, ∞).

An exponential function is given in the function, which has no restrictions, hence the domain is (-∞, ∞).

The range depends of the vertical shift given by k, hence it is given by (k, ∞).

After one year of payments, the amount need to be paid to interest is $1100.42 if the first segment of a five-year amortization schedule is a 5-year amortization schedule option (a) is correct.

It is defined as the systematic way of representation of loan payments according to the time in which the principal amount and interest mentioned in a list manner.

We have a table given that showing a first segment of a five-year amortization schedule that has a 5-year amortization schedule and the amount of interest paid for months 1 through 12.

As the loan amount is not mentioned in the question, we are assuming the loan amount is $1184.6

Therefore, loan amount = $1184.6

The outstanding amount at the end of one year, which is 12 months, is shown in the table as $84.18

After one year of payments, the amount need to be paid to interest:

= Loan amount - Outstanding amount after 12 months

= 1184.6 - 84.18

= $1100.425

Thus, after one year of payments, the amount need to be paid to interest is $1100.42 if the first segment of a five-year amortization schedule is a 5-year amortization schedule option (a) is correct.

The number of fourth graders enrolled in the school is 48.

The number of fifth graders enrolled in the school is 42.

Division is the process of determining the quotient of a number by grouping a number into equal groups using another number.

Number of fourth graders = 8 ÷ 1/6

8 x 6 = 48

Number of fifth graders = 14 ÷ 1/3

14 x 3 = 42

If the density of the man is 1.0321 grams per cubic cm. Then the body fat percentage will be 28.59%.

The function is an expression, rule, or law that defines the relationship between one variable to another variable. Functions are ubiquitous in mathematics and are essential for formulating physical relationships.

An older method of estimating body fat percentage was to measure a person's average density (total mass divided by total volume) and apply a formula to convert it to a body fat percentage.

[tex]\rm BF = \left (\dfrac{4.57}{p} - 4.142 \right) \times 100[/tex]

where BF = body fat and p = density in g/cm3 A man weighs 175 pounds.

A man weighs 175 pounds.

His total body volume is modeled by a cylinder with a height of 170 cm and a radius of 12 cm.

Then the density will be

[tex]\rm p = \dfrac{175 \times 453.592}{\pi \times 12^2 \times 170}\\\\p = \dfrac{79378.7}{76906.19}\\\\p= 1.0321 \ g/cm^3[/tex]

Then the Body fat percentage will be

[tex]\rm BF = \left (\dfrac{4.57}{1.0321} - 4.142 \right) \times 100 \\\\\\BF = 0.2859 \times 100\\\\\\BF = 28.59\%[/tex]

Answer:

the equation is

x - 4 = - 9

the number is

-5

Step-by-step explanation:

First, we don't know the number so we represent it with a variable like "x".

then difference simply means subtraction.

" is" simply means = ( equal to)

so the question says that difference of 4 and a number is 9 so we have x - 4 = -9

so now let's solve for x

we group liked terms and make x stand alone.

x = -9 + 4

( +4 because it crossed an equal sign)

x = - 5

we have

x = -5

so we can substitute the -5 into the equation to if its true

from the equation x - 4 = - 9

where we put -5 instead of x

-5 - 4 = - 9

Using proportions, it is found that when the Axolotl was swimming, 8 breaks were taken.

A proportion is a fraction of a total amount, and the measures are related using a rule of three.

In this problem, in each break there are 6 yards. How many breaks are there in 48 yards? Hence the rule of three is given by:

1 break - 6 yards.

n breaks - 48 yards.

Applying cross multiplication:

6n = 48.

n = 48/6.

n = 8.

8 breaks were taken.

Answer:

[tex]y=\frac{1}{2}x+2[/tex]

Step-by-step explanation:

We can find the slope by using the formula

[tex]\text{slope}=\frac{y_1-y_2}{x_1-x_2}[/tex].

Plugging in the points (2,3) and (6,5), we have

[tex]\text{slope}=\frac{5-3}{6-2}=\frac{2}{4}=\frac{1}{2}.[/tex]

Therefore, the slope is [tex]\frac{1}{2}.[/tex] We can then write the line in slope-intercept form, which is [tex]y=mx+b[/tex] where [tex]m[/tex] is the slope and [tex]b[/tex] is the y-intercept.

We already found the slope, so we know the equation is of the form

[tex]y=\frac{1}{2}x+b.[/tex]

We can now plug in either one of the points to find [tex]b.[/tex] Plugging in (2,3), we get

[tex]3=\frac{1}{2}(2)+b[/tex].

To solve for [tex]b[/tex], we can subtract 1 from both sides of the equation:

[tex]3=1+b[/tex]

[tex]b=3-1=2[/tex].

Now, we have all the variables we need to write the equation in slope-intercept form. We know [tex]m=\frac{1}{2}[/tex] and [tex]b=2[/tex], so the equation is

[tex]y=\frac{1}{2}x+2.[/tex]

Answer:

88

Step-by-step explanation:

(fog)(-g) = f(g(-5))

g(-5) is 20

f(20) is 88

The composition of the function at x = -5,

(fog)(-5) = 88.

Let the two function f(x) and g(x) generate a new function h(x) using an operation.

The operation is composition of functions and h(x) is a composite function.

Given:

Two functions,

f(x) =4x + 8,

and g(x) = x² + x.

g(-5) = 20

The composition of the function at x = -5,

(fog)(-5) = f(g(-5))

(fog)(-5) = f(20)

(fog)(-5) = 20(4) + 8

(fog)(-5) = 88

Therefore, (fog)(-5) = 88
