Solve the problem.A projectile is fired from a height of 7.3 feet with an initial velocity of 122 ft/sec at an angle of 48° with the horizontal. The parametric equations for the path of the projectile are x = (122 cos 48°)t, and y = 7.3 + (122 sin 48°)t - 16t2,where x and y are in feet and t is in seconds. Determine the maximum height reached by the projectile. Round your answer to the nearest tenth of a foot.
