The standard formulation used by the GreatCoat Paint Company for its interior wall paint enables a 1-gallon can to cover 250 square feet. The company's research laboratory produces a new formulation, and
management is anxious to show that it covers the same area, not less. The experiment involves 20 cans of
the new formulation, and this sample gets mean coverage of 237 square feet with a standard deviation of 25
square feet. (17 pts)

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.

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
