Solve the problem.A projectile is fired from a height of 9.2 feet with an initial velocity of 184 ft/sec at an angle of 45° with the horizontal. The parametric equations for the path of the projectile are x = (184 cos 45°)t, and y = 9.2 + (184 sin 45°)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.
