The life expectancy at birth of both sexes in a particular year can be described by the function f(x)=11.51+ 14.71 ln x, where x represents the number of years after 1900. Use this function to determine the life expectancy in 2032.

14. According to the US Department of Health, the average life expectancy from birth for males in the United States may be modeled by the function(x) = 27x + 48.3, where x is the number of years since 1900.

73. Life Expectancy Some scientists believe there is a limit to how long humans can live. One supporting argument is that during the past century, life expectancy from age 65 has in creased more slowly than life expectancy from birth, so eventu ally these two will be equal, at which point, according to these scientists, life expectancy should increase no further. In 1900 life expectancy at birth was 46 yr, and life expectancy at age 65 was 76 yr. In...
