A projectile is launched from the ground with initial velocity & 3 ft per sec. The parametric equations x = 79.8t and y=-16t2 +37.2t model the path of the projectile, where t is in seconds. (a) Determine the angle 8 that the projectile makes with the horizontal at launch. (b) Write parametric equations for the path using the cosine and sine functions. (a) The angle that the projectile makes with the horizontal at launch is 0 (Round to the nearest tenth as needed. Do not include the degree symbol in your answer.) (b) What are the parametric equations using the cosine and sine functions? OA x (88 cos 25.0")t, y = (88 sin 25.0*)t OB. x(25.0 cos 88*)t, y=-1612+(25.0 sin 88*)t OC. x=(88 cos 25.0*)t, y=-161²+(88 sin 25.0")t OD. x=(88 sin 25.0°)t, y=-1612+(88 cos 25.0%)t
