Solve the problem.A projectile is fired from a height of 6.2 feet with an initial velocity of 174 ft/sec at an angle of 46° with the horizontal. The parametric equations for the path of the projectile are x = (174 cos 46°)t, and y = 6.2 + (174 sin 46°)t - 16t2,where x and y are in feet and t is in seconds. Find the height of the projectile after 4 seconds. Round your answer to the nearest tenth of a foot.
A. 244.7 ft
B. 442.9 ft
C. 250.9 ft
D. 483.5 ft
