There are many applications of exponentials and logarithms, including exponential growth and decay, half life, doubling time, Carbon dating, compound interest. Here are a couple of examples. You find out that in the year 1800 an ancestor of yours invested 100 dollars at 6 percent annual interest, compounded yearly. You happen to be her sole known descendant and in the year 2011 you collect the accumulated tidy sum of dollars. You retire and devote the next 10 years of your life to writing a detailed biography of your remarkable ancestor. Strontium-90 is a biologically important radioactive isotope that is created in nuclear explosions. It has a half life of 28 years. To reduce the amount created in a particular explosion by a factor 1,000 you would have to wait years. Round your answer to the nearest integer. Seeds found in a grave in Egypt proved to have only 51% of the Carbon-14 of living tissue. Those seeds were harvested years ago. The half life of Carbon-14 is 5,730 years.
