Answer:

If you wanted to predict the value of the y variable when the x variable is 15, you would be extrapolating the data.

Step-by-step explanation:

If you wanted to predict the value of the y variable when the x variable is 15, you would be Extrapolating the data.

Extrapolation means, estimating the value of a variable beyond its given range.

A rental car company charges $150.00 for a weekly rental and an additional $0.20 for each mile driven. The function rule C = 0.2

son4ous [18]

Answer:

A rental car company charges $150.00 for a weekly rental and an additional $0.20 for each mile driven.

The function $C = 0.20m+ 150.00$ ,

where m is the number of miles and C is the total cost.

Since it is given that : If the rental car can only be driven a maximum of 200 miles.

Then the total cost for this is,

$C = 0.20 (200)+150$ or

$C= 40+150$

On simplify we get,

$C = \$ 190$

A rental Car can only be driven a maximum of 200 miles for a cost of $ 190.

Graph the function : $C = 0.20m+ 150.00$ as shown in the attachment.

A poster is to have an area of 210 in2 with 1 inch margins at the bottom and sides and a 2 inch margin at the top. find the exac

slavikrds [6]

Let

x-------> the length side of the poster

y-------> the width side of the poster

we know that

Area of the poster is equal to

$210=x*y\\\\ y=\frac{210}{x}$ -------> equation $1$

Area of the printed area is equal to

$Aprinted=(x-2)*(y-3)\\ Aprinted=xy-3x-2y+6$ ----> equation $2$

substitute equation $1$ in equation $2$

$Aprinted=[210]-3x-2*[\frac{210}{x}]+6$

using a graph tool

Find the vertex of the graph

The vertex of the graph is the point that represent the value of x for the largest printed area

see the attached figure

the vertex is the point $(11.83,145)$

the largest printed area is $145 in^{2}$

$x=11.83 in$

find the value of y

$y=\frac{210}{x} \\ \\ y=\frac{210}{11.83} \\ \\ y=17.75in$

therefore

the answer is

The dimensions of the poster are $11.83 in x 17.75 in$

You buy a $90 item and it is discounted by $18. What is the discount's percentage?

gogolik [260]

Answer:

Hey the answer is 20%.

Step-by-step explanation:

You multiply the $90 with 20%,

but in order to figure that out you need to:

Calculate the savings: 20% of $90 = $18.

Subtract the savings from the original price to get the sale price: $90 - $18 = $72. You're all set!

Answer:

<h3>x= 51°</h3><h3>Exterior angle = 131°</h3>

Step-by-step explanation:

We know that exterior angle means the sum of 2 opposite interior angles.

So,

<h3>According to the question</h3>

$80 + x = 3x - 22$

$= > 3x - 22 = 80 + x$

$= > 3x - x = 80 + 22$

$= > 2x = 102$

$= > x = \frac{102}{2}$

$= > x = 51$

So,

x= 51°

Now,

∠exterior = 3x -22°

$= > 3(51) - 22$

$= > 153 - 22$

$= > 131$
