4.if cotθ = -√15/7 , use the fundamental identities to find cosθ > 0
9.A projectile is fired with an initial velocity of 88 ft/sec at an angle of 35° to the horizontal. Neglecting air resistance, what is the time of impact? (Round to the nearest tenth of a second.)
Remember: x = (v↧0cosθ)t and y = h↧0+ (v↧0sinθ)t – 16t^2
