Chapter 1.1, Problem 43E

Find an expression for the function whose graph is thegiven curve.   The top half of the circle x2+ (y-2)2=  4

Let x=0 represent 1995, x=5 represent 2000 and so on., A. Use (0,32) and (25,76) to find the equation of a line that approximates the other ordered pairs. Use the form f(x) =ax + b.  The equation of the line is f(x)=1.76) x + 32. Use this equation to estimate the amount of nuclear wast in 2018.
