The first thing to do in this case is to replace the value of x = 60 in the given function to obtain the average fuel mileage in miles per gallon.
 We then have to replace:
 y = -0.0088 * x ^ 2 + 0.79 * x + 15
 y = -0.0088 * (60) ^ 2 + 0.79 * (60) + 15
 y = 30.7 mi / gal
 answer
 the best approximate for the average gas mileage at a speed of 60 miles per hour is
 B) 30.7 mi / gal

A circle has an area of 30 in^2. What is the area of a 60 sector of this circle?
yuradex [85]

We use the ratio x:360 to find portions of the circle (again, through the ratio)

so we use 60/360 = x/30 in^2

1/6 = x/ 30

x = 5.

The answer is 5 in^2
