A box is to be constructed with a rectangular base and a height of 5 cm. If the rectangular base must have a perimeter of 28
cm, which quadratic equation best models the volume of the box?
V = lwn
P = 2(1 + w)
y = 5(28 - x)(x)
y = 5(28 - 2x)(x)
y = 5(14 - x)(x)
y = 5(14 - 2x)(x)

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.

answer: i guess 5 units?
