For each problem below, given the stopping distance, determine the safe speed. How many lamps must be sold and produced to break even? (Hint: We break even when the profit is zero.)Īssuming dry road conditions and average reaction times, the safe stopping distance, d in feet of an average car is given using the formula d = 1 20 v 2 + v, where v represents the speed of the car in miles per hour. The profit in dollars generated by producing and selling x custom lamps is given by the function P ( x ) = − 10 x 2 + 800 x − 12000. (Hint: The hypotenuse is the longest side. The sides of a right triangle have measures that are consecutive integers.
