(3x^2)^2/3

Will give 50 points

4.26

Step-by-step explanation:

3^2= 9

2/3= .66

9^.66

x/7.50 = 15

x= 7.50 / 15 divide

step-by-step explanation:

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.
