University of Michigan Runs his own tutoring company Carl taught upper-level math in several schools and currently runs his own tutoring company.He bets that no one can beat his love for intensive outdoor activities!This question can be answered using a little bit of calculus. Once we have an expression for t, a "definite integral" will give us the mean value of t (this is how "mean value" is defined).From the equation above, taking logarithms of both sides we see that lt = -ln(N/N.In his article Light Attenuation and Exponential Laws in the last issue of Plus, Ian Garbett discussed the phenomenon of light attenuation, one of the many physical phenomena in which the exponential function crops up.In this second article he describes the phenomenon of radioactive decay, which also obeys an exponential law, and explains how this information allows us to carbon-date artefacts such as the Dead Sea Scrolls.In the previous article, we saw that light attenuation obeys an exponential law.

We take a natural log because it's the base e, we could take the log, but then we'd be left with a log b, so we take the natural log, this is going to make our base to disappear.We have 71%, so what I can do is just say .71 times our original amount.If you have and I have 2/3 of the amount of money you have, you take 2/3 times 5.Natural log point 71 is equal to negative, it's very small decimal t, natural log of e, natural log of e is just 1, so to solve this out we just divide by this decimal natural log of .71 divided by .00012 is equal to t.Finish up plug in your calculator, natural log .71 divided by negative .123, 12 and this gives us around 2854 years.
