Solve the problem.A projectile is fired from a height of 9.3 feet with an initial velocity of 184 ft/sec at an angle of 40° with the horizontal. The parametric equations for the path of the projectile are x = (184 cos 40°)t, and y = 9.3 + (184 sin 40°)t - 16t2,where x and y are in feet and t is in seconds. Determine the rectangular equation describing the path of the projectile.
