Find parametric equatiens fer the line that is tangent to the given curve at the given parameter value. rm: [12} i+{5t4]j+ [5?] k. t=t =3 What is the standard parameterizatien for the tangent line? D D we [Type expressions usingt as the variable.) 3H II He: II 1/3 Evaluate the integral [(2 sin t) i + (4+ cost) j+ (2 sec? t) k] at. - 1/3 The result is i+ (Di+ (). (Type exact answers, using x and radicals as needed.)A projectile is fired at a speed of 860 m/sec at an angle of 60". How long will it take to get 22 km downrange? The projectile will take seconds to get 22 km downrange. (Round to the nearest hundredth.)A projectile is fired at a speed of 860 m/sec at an angle of 60" .
