Suppose the rate of change of the expected life span l at birth of people born in

Question:

Suppose the rate of change of the expected life span l at birth of people born in the United States can be modeled by
dl 14.304 dt t+ 20

where t is the number of years past 1920.

Life Span (years) Year Life Span (years) Year 1920 1994 1996 54.1 75.7 1930 59.7 76.1 1940 62.9 1998 76.7 1950 68.2 2000

(a) Use integration and the data point for 2000 to find the function that models the life span.
(b) The data in the table give the expected life spans for people born in various years. Graph the function from part (a) with the data, with t = 0 representing 1920.
(c) How well does the model fit the data?
