1. a community pool that is shaped like a regular pentagon needs a new cover for the winter months. the radius of the pool is 20.10 ft. the pool is 23.62 ft on each side. to the nearest square foot, the area of the pool that needs to be covered is   ft^2 2. a square has an apothem measuring 2.5 cm and a perimeter of 20 cm. what is the area of the square, rounded to the nearest square centimeter? a. 13 cm ^2 b. 25 cm ^2 c. 50 cm ^2 d. 100 cm ^2

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.
