Question 91588: 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.
1. Write the formula for natural exponential growth for this particular prairie dog population.
Hint: Find the "k" value for this population, and put it in your formula.
2. Once you have this formula, predict:
a. approximately how many years from now will the population reach 365 prairie dogs.
b. approximately how large the population will be 10 years from now.
3. Write the formula for compound interest and calculate how much money your friend will have on deposit (in the account described above) after 20 years (10 years from now).
Answer by stanbon(75887)   (Show Source):
You can put this solution on YOUR website! I think you need the dog count from another year
to find the exponential equation you are looking for.
Check to see if you posted the problem as it is stated
in your text.
Cheers,
Stan H.
