Braking Distance.
Find a quadratic function that fits the following data.
Travel Speed (mph) | Braking Distance (ft) |
20 | 25 |
40 | 105 |
60 | 300 |
(Source: New Jersey Department of Law and Public Safety.) |
b. Use the function to estimate the braking distance of a car traveling at 50 mph.
c. Does it make sense to use this function when speeds are less than 15 mph? Why or why not?

Give your answer in terms of π. square feet (b) If the cost to clean the oil spill is proportional to the square of the diameter of the spill, express the cost, C, as a function of the radius of the spill, r. Use a lower case k as the proportionality constant.
