A species of fish was added to a lake the population size P(t) can be modeled by the following function where t is the number of years from the time the species was added to the lake P(t)=2800÷1+3e^-0.4t

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.

d

gimmee one of those gold crowns!
