The minimum breaking distance d in feet for a typical vehicle can be modeled with the equation d (v) = 0.045v2, where v is the vehicle's speed in miles per hour. The minimum braking distance for a vehicle with new tires at optimal inflation is d (v) = 0.039v2. What kind of transformation describes this change from d (v) = 0.045v2 to d (v) = 0.039v2, and what does this transformation mean?

a. Horizontal compression by a factor of 13/15; the braking distance will be more with optimally inflated new tires than with tires having more wear.

b. Horizontal compression by a factor of 13/15; the brakin
