Try
where initial population, r = growth rate and t = time in years and P=
you should find
years
Dear Forum I am having problems with the following any feedback would be appreciated:
If the population in a particular country is growing at 1.7% compounded continuously, how long will it take the population to double? (Round up to the next higher year if not exact.)
thanks -AC-
Something fishy going on there. ln(2)/1.07 < 1. It's growing at 1.7% per year and doubles in less than a year?
Using the classical Rules of 72, we get an approximation of 72 / 1.7 = 42.353 years. Let's find a model that produces a result in this neighborhood.
Or, if you insist on e-base.
