Solve the problem.A projectile is fired from a height of 9 feet with an initial velocity of 144 ft/sec at an angle of 30° with the horizontal. The parametric equations for the path of the projectile are x = (144 cos 30°)t, and y = 9 + (144 sin 30°)t - 16t2,where x and y are in feet and t is in seconds. Find the total horizontal distance traveled by the projectile. Round your answer to the nearest tenth of a foot.
