Which expressions are equivalent to 2^−4·2^2? 1) −1/4
2) 4
3) 1/2^2
4) -4
5) 1/4
6) 2^-2
7) 2^2

the answer is 6)

Step-by-step explanation:

Because . = =

I hope it right

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.
