So, the possible out comes for each one of the letters = 26

And the possible out comes for each one of the numbers = 10

7. Answer is D! 1 to the 3rd power, 1^3, or 1 cubed as you'll hear it, is 1 because when something is cubed that means it's times itself 3 times. (EX: 4^3 = 4x4x4) 2 cubed is 8. 3 cubed is 27. 4 cubed is 64 and 5 cubed is 125!

8. Answer is C! A is gaining speed and B is the capped speed, meaning it can't get any higher, and C is the loss of speed.

natali 33 [55]

Answer:

1/5

Step-by-step explanation:

m = ( y2-y1)/(x2-x1)

    = ( 3-0)/(7 - -8)

    = ( 3-0)/(7+8)

     = 3/15

    = 1/5
