A rescuer on a helicopter that is 50 feet above the sea drops a lifebelt. The distance from the lifebelt to the sea can be modeled by the equation h (t) = -16t + s, where t is the time, in seconds, after the lifebelt is dropped, and s is the initial height, in feet, of the lifebelt above the sea. How long will it take for the lifebelt to reach the sea? Round your answer to the nearest tenth of a second. Hint: Let h (t) = 0 and replace s with the initial height of the lifebelt. Then solve for t. Ot=1.7 Ot=1.8 Ot= 3.125 Ot=-18

Linear Functions

A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.
