Problema Solution
One of the games at a carnival involves trying to ring a bell with a ball by hitting a lever that propels the ball into the air. The height of the ball is modeled by the equation h(t) =16t2+ 39t. If the bell is 20 ft. above the ground, will it be hit by the ball?
Answer provided by our tutors
16t^2 + 39t = 20
by solving the quadratic equation we find
