Question 37256
The number of miles,M,that a car can travel on a gallon of gas depends on the average speed,v,of the car in miles per hour. A travel researcher has compiled the following data for his car.

     v   44    50    53    56    60    70

     M  35.9  37.5  38.0  38.3  38.4  37.1

a. Find a quadratic model for M in terms of v.
M(v)=-0.011x^2+1.30x-0.019
This from using the TI-83 "Quadratic Regression".


b. Use your model to predit M when v = 65
Again using TI-83 get M=38.025
