Doug digs a hole that is 1.7 feet below ground level. He plants a bush that is 3.2 feet tall from the bottom of the root to the top branch. How much of the bush is above the ground? Draw a picture to help you.

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.
