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.

The number of fish in a lake can be modeled by the exponential regression equation y=14.08 x 2.08^x where x represents the year
