Save & Exit Certify Lesson: 3.5 Critical Values and the First De... Question 4 of 10, Step 1 of 1 5/18 Correct MARLON GALLO 2 The fuel consumption of an automobile is not constant. Fuel economy depends largely on the speed of the vehicle. The function 213 449v2 F(v) = + 18,675 12,450 132v 415 +90 (F(v) is in miles per gallon) describes the fuel consumption of a new hybrid vehicle, where 0 < y < 95 is the velocity of the vehicle. Which velocities yield maximum efficiencies? (Remember, high efficiency means low consumption.) Round your answer to one decimal place. If necessary, round any intermediate calculations to six decimal places. Enter DNE if there is not a local extremum. Answer v = Keypad Keyboard Shortcuts
