If the original quantity is 15 and the new quantity is 19, which is the best estimate for the percent change?

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.

the answer is y = 11.54

hope this : )

where is the diagram? shown below where? ?

step-by-step explanation:

it would rotate about 180 degrees.
