Estimate the number 7.616 to show that the number 76.16 is not correct.

there is a one decimal placement difference

Step-by-step explanation:

7.616 is one decimal less than 76.16 essentially meaning it’s 10 times more than 7.616

i'm assuming it's looking for the missing length, which should be 4cm

hope this !

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.
