You need to find the slope first. (-9,-4). (3,4)

-4-4= -8
-9-3 =-12. Slope is -8/-12 or 8/12 or 2/3

Perpendicular is the negative reciprocal. Or flip over the 2/3 and make it negative.

The answer is - 3/2

The change in y as we move from the first point to the second is 8, and the corresponding change in x is 12. Thus, the slope of the line thru these two points is 8/12, or 2/3 (answer C).

What is the area of the circle?

AlexFokin [52]

Answer:

530.93

Step-by-step explanation:

area of a circle = πr²

where r = radius

here we are given the diameter

to convert to radius , we divide by 2

so radius = 26 / 2 = 13

so we have A = πr²

==> plug in r = 13

A = π13²

==> evaluate exponent

A = 169π

==> multiply 169 and π

A = 530.93 ( approximately )

Step-by-step explanation:

Find the quotient:

$36.75/$36.00

This comes out to 1.021,

so the inflation rate is 1.021 - 1.000 = 0.021 or 2.1%/year
