A particular country's exports of goods are increasing exponentially. The value of the exports, t years after 2006, can be approximated by V(t) = 1.3 e . where t= 0 corresponds to 2006 and V is in billions of dollars. a) Estimate the value of the country's exports in 2006 and 2016. b) What is the doubling time for the value of the country's exports? . . . a) The value of the country's exports in 2006 is $ billion. (Simplify your answer. Round to the nearest tenth as needed. Do not include the $ symbol in your answer.)
