Hi, 1108888 here. Just want to say that I will delete my account shortly. I already created another account because I liked being a beginner. You can delete my question if you want.

The height of a flare fired from the deck of a ship in distress can be modeled by h(t)= -2(8t^2-52t-28), where h is the height of the flare above water and t is the time in seconds. a. find the time it takes the flare to hit the water.
