Question

The horsepower H required to overcome wind drag on a certain automobile is approximated by H(x) = 0.006x2 + 0.005x - 0.025, 10 x 100, where x is the speed of the car in miles per hour. Find H(x/1.9). Round the numerical values in your answer to five decimal places. H(x/1.9) = 0.00263x2 + 0.00166x - 0.02500 H(x/1.9) = 0.00087x2 + 0.00263x - 0.02500 H(x/1.9) = 0.00166x2 + 0.00087x - 0.02500 H(x/1.9) = 0.00166x2 + 0.00263x - 0.02500 H(x/1.9) = 0.00087x2 + 0.00166x - 0.00263 Determine whether t is a function of x. xy - x2 = 9y + x
