The length and width of a rectangle can be expressed as x+3 and x-8 . If the area of the rectangle is 60 square inches , what is the value of x?

Step-by-step explanation:

The graph shown represents the volume of  petroleum in a spherical tank with a 15-foot radius as a function of the height of the liquid, in feet. This relationship can be modeled by the equation y = 15πx2 − πx3. What is the approximate height of the petroleum in the tank when the volume is 5,300 ft3?

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.

a is the right answer
