Question

66. U.S. Imports. The amount of imports to the United States has increased exponentially since 1980 - (Sources: U.S. Census Bureau; U.S. Bureau of Economic Analysis; U.S. Department of Commerce). The exponential function 1(x) = 297.539(1.075)*, where x is the number of years after 1980, can be used to estimate the total amount of U.S. imports, in billions of dollars. Find the total amount of imports to the United States in 1995, in 2005, in 2010, and in 2013. Round to the nearest billion dollars.

Answer 1

566 Groven Goven exponential exponential sa is 7 (x) = 297.539 (10075) * Noo, For year 1995 x= 1995- 1980 =15. I (15) = 297.539 (1.075) "S = 297.539) x 2.96. = 880.4. I(15) = $880 bu of In 1995 Ienpost was apprea $880bn. For 2005 x= 2005-1980 = 25. I (25) = 297.539 (10075) 25 - 297 539 X 6.09. = 1814.49. 1814.5 I (25) $1815. 1 th 2005 Import was approx $1815 by For year 2010 - 2010 - 1980 = 30 I (30) =297.539 (10078) 30 - 297.539 x 8.75 - 2604.9 2010 Impost was approx $2605 by ,) In 2010 Impo

For year 2013 - 2013-1980 - 3 . I (33) = 294.539 (40075)^3 - 2970539 x 10.9 - 3236 01 t for year 2013, import was approx. $3236 by
