Concept explainers
The data in the graph show the wind speed y (in mph) for Hurricane Katrina versus the barometric pressure x (in millibars, mb). (See. Example 7)
a. Use the points (950, 110) and (1000, 50) to write a linear for these data.
b. Interpret the meaning of the slope in the context of this problem.
c. Use the model from part (a) to estimate the wind speed for a hurricane with a pressure of 900 mb.
d. The lowest barometric pressure ever recorded for an Atlantic hurricane was 882 mb for Hurricane Wilma in 2005. Would it be reasonable to use the model from part (a) to estimate the wind speed for a hurricane with a pressure of 800 mb?

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.
