Movement of the Pacific Plate The Pacific plate (the
floor of the Pacific Ocean) near Hawaii is moving at
about 0.000071 kilometer per year. This is about the
speed at which a fingernail grows. Use scientific nota-
tion to determine how many kilometers the Pacific
plate travels in 1 million years.

- Freight on Class I Railroads According to the Association of American Railroads, Class I freight railroads are the line-haul freight railroads with 2006 operating revenue in excess of 346.8million. Let F=F(t) denote the freight revenue in billions of dollars of Class I railroads in year t. In 2005, Class I railroads had a freight revenue of 44.5billion. In 2007, the revenue was 52.9 billion. Calculate the average rate of change per year in F from 2005 to 2007 and explain its meaning in practical terms.arrow_forwardMilk Production Milk production M (in billions of pounds) in the United States from 2000 through 2014 can be modeled by M=3.00t+163.3,0t14 where t represents the year, with t = 0 corresponding to 2000.
