Brynn and Denise launch their rockets at the same time. The height of Brynn’s rocket, in meters, is given by the function f(x)=−4.9x2+75x, where x is the number of seconds after the launch. The height of Denise’s rocket, in meters, is given by the functiong(x)=−4.9x2+50x+38, where x is the number of seconds after the launch. There is a moment when the rockets are at the same height. What is this height? Enter your answer, rounded to the nearest tenth of a meter, in the box.
