Question:
Air Pollution Tiny particles suspended in the air are necessary for clouds to form. Experts believe that air pollutants may cause an increase in cloud cover. From 1930 to 1980 the percentage of cloud cover over the world's oceans was monitored. The formula f(x) = 0.06(x- 1930) + 62.5 for 1930 x 1980 approximates this percentage. (Source: W. Cotton and R: Pielke, Human Impacts on Weather and Climate.)
(a) Evaluate the expressions f(1930) and f(l980). How did the amount of cloud cover over the oceans change during this 50-year period?
(b) What does f1 (x) compute?
(c) Use part (a) to evaluate f1 (62.5) and f1 (65.5). (d) Find f1 (x).
