1.Express as a difference of logarithms.
This is a simple problem if you know the properties of logarithms. One of them is: . This says we can write a log of a quotient as the difference of the logs of the dividend and divisor. We have the log of a quotient and we want to write it as a difference of logs:
2.Yearly sales of an electronic device S(t), in millions of dollars, t years after 1998 can be estimated by
S(t) = 100 ∙ 6t .
What is the doubling time for the yearly sales?
==========
This problem makes no sense. S(t) is the equation of a line with a negative slope. A line with a negative slope means that S(t) is constantly decreasing. S(t) will never double. In fact it will never go up at all!
