90 points PLZ HURRY Express 7 as a fraction. A) 1 7 B) 14 2 C) 2 7 D) 20 3

B) 14/2

Step-by-step explanation: 1/7 is a smaller number over a larger number, and we want a larger number over the bottom number for a whole number. 2/7 is the same reason. 20/3 as a whole number is 6 and 2/3 so no. 14/2 is the only answer

constant acceleration- a

constant velocity- c

no velocity or acceleration- b

explanation:

for body moving with a constant acceleration, the rate of change of displacement changes over time. this is proven by the increasing gradient of the curve (a) against time.

a body that is moving at constant velocity covers equal distances over equal periods of time, thus the straight line with a constant gradient c.

a stationary body   covers no displacement as time elapses. thus the flat line with   zero gradient.

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 : )
