According to a study, the Dow Jones index during the period 2010-2018 is given by I(t) = 2t^2 - 73t + 28344 (6 ≤ t ≤ 16) (t = 6 represents 2006). What was the average rate of change of the Dow Jones Index during the period from 2006 to 2014? Result (points per year): Response
Added by William M.
Step 1
Step 1:** Calculate \(I(14)\) by plugging in \(t = 14\) into the equation \(I(t) = 2t^2 - 73t + 28344\): \[I(14) = 2(14)^2 - 73(14) + 28344\] \[I(14) = 2(196) - 1022 + 28344\] \[I(14) = 392 - 1022 + 28344\] \[I(14) = 28314\] ** Show more…

The unemployment rate of a certain country shortly after the Great Recession was approximately (5t + 29.8) / (t^2 + 25) percent in year t, where t = 0 corresponds to the beginning of 2010. How fast was the unemployment rate of the country changing at the beginning of 2013? (Round your answer to two decimal places) %/year

The Consumer Price Index is reported monthly by the U.S. Bureau of Labor Statistics. It reports the change in prices for a market basket of goods from one period to another. The index for 2003 was 203.1. By 2013, it increased to 243.100. What was the geometric mean annual increase for the period? (Round your answer to 2 decimal places.)
