The diameter of a circle is 20 kilometers. What is the angle measure of an arc 7 kilometers long?

Step-by-step explanation:

Θ = 57.3°(7 km)/10 km = 40.11°

answer: a) (0,0), (1,1), (2,8), and (3,27).

step-by-step explanation:

0^3=0

1^3=1

2^3=8

3^3=27

in effect, the exponential equation for this would me y=3^x. each x-coordinate cubed is giving the y coordinate, so a is your answer : )

cross multiplying, we get :

⇒ (3) × (5) = (9) × (x)

⇒ 15 = 9x
