Ryo is standing on his deck, which is 20 feet off the ground. He throws a tennis ball off of his decl. The equation h(t)=-16t^2+32t+20 models the ball's height, h, in feet from the ground a t seconds after he threw it. what is the ball's maximum height?

The magnitude, m, of an earthquake is defined to be m=log l/s, where i is the intensity of the earthquake (measured by the amplitude of the seismograph wave) and s is the intensity of a “standard” earthquake, which is barely detectable. what is the magnitude of an earthquake that is 1,000 times more intense than a standard earthquake? use a calculator. round your answer to the nearest tenth.
