Question 1173497: An event in the Summer Olympics is 10-meter springboard diving. In this event, the height s, in meters, of a diver above the water t seconds after jumping is given by s(t) = - 4.9t2 + 7.3t + 10. What is the maximum height that the diver will be above the water? Round to the nearest tenth.

You can put this solution on YOUR website!
s(t) = - 4.9t2 + 7.3t + 10
vertex t value is at -b/2a or -7.3/-9.8=0.7449
f(0.7449)=12.719 m. or 12.7 m,
