Create a quadratic equation then solve the equation with a related function. you can use a table, graph, or graphing calculator.

a skydiver jumps out of a plane 5,000 feet above the ground and her parachute opens 3,000 feet above the ground. the function h(t) = -16t^2 + 5,000, where t represents the time in seconds, gives the height h, in feet, of the skydiver as she falls. when does her parachute open? round to the nearest second.
