A particular country's exports of goods are increasing exponentially. The value of the exports, t years after 2005, can be approximated by V(t) = 1.3 e 0.038t where t=0 corresponds to 2005 and V is in billions of dollars. a) Estimate the value of the country's exports in 2005 and 2017. b) What is the doubling time for the value of the country's exports? a) The value of the country's exports in 2005 is $ billion. (Simplify your answer. Round to the nearest tenth as needed. Do not include the $ symbol in your answer.) The value of the country's exports in 2017 is $ billion. (Simplify your answer. Round to the nearest tenth as needed. Do not include the $ symbol in your answer.) b) The doubling time is approximately years. (Simplify your answer. Round to the nearest integer as needed.)

Linear Functions

A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.
