A15 foot pole extends t feet below ground and10 feet above ground . choose the linear equation that models the situation.

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.

to rewrite a literal equation you may need to divide by a number, or by a variable.

hope i .

the discriminant is 64 + 4*1*12 = 112

this is prime.
