Solve the problem.The table shows the population of a certain city in various different years. Use regression to find values for a and b so that f(x) = axb models this data, where x represents the number of years since 1980 and f(x) is the population of the city in hundreds of thousands. Round your answers to 5 significant digits.
A. a ? 1.8506, b ? 0.51209
B. a ? 2.6352, b ? 0.47558
C. a ? 2.1375, b ? 0.44316
D. a ? 1.7025, b ? 0.53750
Answer: B

A variable force of magnitude F(x) moves a body of mass m along the x-axis from x1 to x2. The net work done by the force in moving the body from x1 to x2 is 
where v1 and v2 are the body's velocities at x1 and x2. Knowing that the work done by the force equals the change in the body's kinetic energy, solve the problem.How many foot-pounds of work does it take to throw a baseball 60 mph? A baseball weighs 5 oz, or 0.3125 lb.
