On a given day, the flow rate F (in cars per hour) on a congested roadway is given by the equation below, where v is the speed of traffic in miles per hour. V F = 20 + 0.07v2 What speed will maximize the flow rate on the road? (Round your answer to one decimal place.) mi/hUse the information to find and compare Ay and dy. (Round your answers to three decimal places.) y = 0.4x x = 1 Ax = dx = 0.1 Ay = 0.2 X dy = 0.200
