A rocket carrying fireworks is launched from a hill above a lake. The rocket will fall into the lake after exploding at its maximum height. The rocket's height above the surface of the lake is given by the function  $h\left(t\right)=-16t^{2\ }+64t+80.$  What is the initial height of the rocket? (only write the number)

A rocket carrying fireworks is launched from a hill above a lake. The rocket will fall into the lake after exploding at its maximum height. The rocket's height above the surface of the lake is given by the function   $$h\left(t\right)=-16t^2+64t+80.$$ What is the height of the rocket after 2 seconds?

A rocket carrying fireworks is launched from a hill above a lake. The rocket will fall into the lake after exploding at its maximum height. The rocket's height above the surface of the lake is given by the function   $$h\left(t\right)=-16t^2+64t+80.$$  How long will it take for the rocket to reach a height of 140 feet?(Only write the number)

One of the games at a carnival involves trying to ring a bell by hitting a lever that propels the ball into the air. The height of the ball is modeled by the equation  $$h\left(t\right)=-16t^2+48t.$$  What is the maximum height of the ball? Will the ball reach the bell if the bell is 40 feet above the ground?

A ball is thrown upward from a height of 20 ft with an initial velocity of 17 ft/s. Use the formula  $$h\left(t\right)=-16t^2+17t+20\$$  to find how long it will take for the ball to hit the ground.
