Tests show that the power P (in hp) of an automobile engine as a function of r (in r/min) is given by P = 5.0 10 6 r 2 + 0.050r 45(1500 < r < 6000 r/min). Sketch the graph of P vs. r and find the maximum power that is produced.
Chapter 7, Exercises 7.4 #44
Tests show that the power P (in hp) of an automobile engine as a function of r (in r/min) is given by P = −5.0 × 10−6r2 + 0.050r − 45(1500 < r < 6000 r/min). Sketch the graph of P vs. r and find the maximum power that is produced.
