Set up an algebraic equation and then solve the following problems. the height of an object dropped from the top of a 64-foot building is given by h(t)=-16t^2+64. how long will it take the object to hit the ground?

An arrow is shot vertically upward at a rate of 180ft/s. use the projectile formula h=−16t2+v0t to determine at what time(s), in seconds, the arrow is at a height of 420ft. round your answer(s) to the nearest tenth of a second.

Determine whether the angles in each given pair are coterminal. 744°, -336°
