I'm not an expert, but from what I remember, the y-intercept is where the line passes the y-axis, so in this case, it would be 4. In order to get to the next point, you would have to go down 4 points and left 2, which would be 4/2 = 2/1 = 2. Take my answer with a grain of salt, but I think it would be y = 2x + 4. There doesn't seem to be a graph with squares, so I can't be absolutely certain.

A function and its inverse are shown on the graph. Which statement describes the relationship between the function and its inver

WARRIOR [948]

Answer:

Option (B)

Step-by-step explanation:

Domain of function is defined by the set of x-values (input values) and Range of a function is a set of y-values (output values).

From the graph attached,

Domain of f(x) → Set of all real numbers

Range of f(x) → y-values > 0

Domain of $f^{-1}(x)$ → Set of all real numbers

Range of $f^{-1}(x)$ → y < 2

Therefore, domain of both the functions is a set of all real numbers.

Option (B) is the correct option.

Find the area of the regular polygon below. leave your answer in simplest radical form.

Licemer1 [7]

Answer:

384√3 in²

Step-by-step explanation:

Given in the question a regular 6 sided polygon

To find it's area you have to use the following formula

<h3> 1/2 x perimeter x apothem</h3>

<em>Perimeter = the sum of the lengths of all the sides </em>

<em>Suppose length of one side = x</em>

<em>Apothem = a segment that joins the polygon's centre to the midpoint of any side that is perpendicular to that side = 8√3</em>

<em />

Since the polygon have 6 sides so

perimeter = 6x

x = 2(8)

x = 16

perimeter = 6(16) = 96 in

plug values in the formula of area

384√3 in²

The state of New Jersey makes approximately $1.55 billion annually from tolls of the $1.55 billion about 3/4 comes from tolls on

Rama09 [41]

Percent of turn pike is 75% and percent of parkway is 25%.

<u>Solution:</u>

Given, The state of New Jersey makes approximately $1.55 billion annually from tolls of the $1.55 billion

About $\frac{3}{4}$ comes from tolls on the turnpike

Remaining $\frac{1}{4}$ comes from tolls on the parkway

<em><u>To find the percent of the total revenue from turnpike:</u></em>

$\begin{array}{l}{\text { Percent of turnpike }=\frac{\text { amount from parkway }}{\text { total revenue }} \times 100} \\\\ {=\frac{\frac{3}{4} \text { of total revenue }}{\text { tot al revenue }} \times 100} \\\\ {=\frac{\frac{3}{4} \times \text { total revenue }}{\text { total revenue }} \times 100} \\\\ {=\frac{3}{4} \times 100=3 \times 25=75 \%}\end{array}$

<em><u>To find the percent of the total revenue from parkway:</u></em>

$\begin{array}{l}{\text { Percent of parkway }=\frac{\text { amount from parkway }}{\text { total revenue }} \times 100} \\\\ {=\frac{\frac{1}{4} \text { of total revenue }}{\text { total revenue }} \times 100} \\\\ {=\frac{\frac{1}{4} \times \text { total revenue}}{\text { total revenue }} \times 100} \\\\ {=\frac{1}{4} \times 100=25 \%}\end{array}$

<em><u>Summarizing the results:</u></em>

Percent of turn pike is 75%

Percent of parkway is 25%
