Use the model to show why 522 is divisible by 9.​

If the sum of the digits is divisible by 9, then 522 is divisible by 9. If the sum of the digits is not divisible by 9, then 522 is not divisible by 9. 9 is divisible by 9, Therefore, 522 is divisible by 9 and the answer to the question, "Is 522 Divisible By 9?" is Yes.

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.
