The height of a pebble dropped from a cliff 604 feet high is described by the formula . How long will the pebble take to reach a height of 348 feet?

The path of the water from a sprinkler is modeled by a quadratic function where h(d) is the height of water, in feet, at a distance of d feet from the jet. Find how far from the sprinkler the water hits the ground.

A rocket is fired with a velocity of 60 m/s at a vertical angle of 30 degrees. The equation gives the height of the rocket at t seconds after the launch. Will the rocket ever reach a height of 50 meters? Explain your reasoning.
