The percent of paper and paperboard that is recycled from municipal solid waste has grown exponentially. The table lists Percent of paper the percentages for selected years. Use a graphing calculator to fit the data to an exponential function. Use the function Year, x recycled, R(x) to find R in 2008. In what year will the percentage exceed 70? 1980, 0 21.5 1990, 10 27.6 1994, 14 35.4 Type the values from your calculator for a and b for the exponential function y = ab*. 1995, 15 40.1 a= 1996, 16 40.5 1997, 17 40.4 b = 1998, 18 40.9 (Round to six decimal places as needed.) 1999, 19 41.2 2000, 20 44.2
