He points (-9,-4) and (3,6) are the endpoints of the diameter of a circle. find the length of the radius of the circle.

First end point of the diameter of a circle = (-9,-4).

Second end point of the diameter of a circle = (3,6).

Let us find length of the of the diameter of the circle by using distance formula.

We know distance formula,

We have (x1, y1) =  (-9,-4) and (x2,y2) = (3,6).

Plugging values of x1,y1, x2 and y2 in above distance formula.

=

Factoring out heighest perfect square from 244.

244= 4* 61.

Square root of 4 is 2.

Therefore, diameter of the circle =

Radius is half of diameter.

So, dividing value of diameter by 2, we get

Radius =

false

step-by-step explanation:

4y - 6 + 4y^2 - 9

before simplifying this contains 4 terms

after simplifying

4y -15 + 4y^2

it contains 3 terms

location: point 0

step-by-step explanation:

well, -8 to 10 on a number line is 18 spaces.

1/9 of 18 is 2.

so, 4/9 of 18 must be 8.

8 spaces from -8 (a) is 0.

so, 4/9 of the way from -8 to 10 is 0!
