Ten years ago your friend invested in a plot of land with the idea of eventually building a summer cottage on it. His plan was to place a "nest egg" of $12,000 in a long term Certificate of Deposit which paid 8% interest over a period of 20 years, compounded monthly. At the end of the 20 years, he would use the money to build the cottage.
The problem was the plot had 8 prairie dogs on it 10 years ago when he acquired the ground.
This year he made a count of the prairie dogs and found there were 102 on the same plot! A biologist friend assured him that the prairie dogs were growing exponentially according to the law of natural growth, and something needed to be done.
So....
1) What would be the FORMULA for the exponential growth of the prairie dog population.
2)approximately how many years from now will the population reach 365 prairie dogs.
3) approximately how large the population will be 10 years from now

For my entire life, I can't sleep in on weekends because it is blindingly sunny in the morning, never foggy or dark. WHY! I have finally figured out this is not a coincidence. There must be a scientific reason for this.

I'm thinking maybe that due to electromagnetic force, the elctrecity can by harnested. If we connect a tube with some kind of flow of positibley charged protons or maybe ions that are positively charged, the positive will attract the negative? Does this make sense?

My math books just lists the definition of functions which are continuous intervals (i.e. they are continous on every point of that interval etc...), but a question asks you to find the intervals over which a function is continous (e.g, f(x) = x + sqrt(1 - x^2) ) and I couldn't find a method for that anywhere? Isn't there a particular technique for doing that, like there is for proving a function is continuous on a point?
