Hello I have a question for this problem A penny is thrown from the top of a 30.48-meter building and hits the ground 3.45 seconds after it was thrown. The penny reached its maximum height above the ground 0.823 seconds after it was thrown. The quadratic function h expresses the height of the penny above the ground (measured in meters) as a function of the elapsed time, t, (measured in seconds) since the penny was thrown. What are the zeros...
