20 points Sebastian and Sabrina have gone on
vacation in Atlantic City. Their first
stop was the pier, where they noticed
horse diving and both decided to give
it a try. Sebastian went first. His dive
was modeled by the equation,
h(t)=-16t² + 16t+18, where h is the
height (in feet) above the water and
t is the time in seconds. Sabrina's
dive is modeled by
h(t)-16(-0.5)² + 22.
