    Growth of population

    After a particularly harsh winter, the regrowht of a population of rabbits in an area is given by the function

    P(T)=500 ALL OVER 1+e^-t

    Determine the rate of growth after 3 years.

    I kno how to do it if there was a number instead of the E, but i do not know what to do with the E there...

    But "e" is a number! It's the natural exponential and the base of the natural logarithm, and is approximately equal to 2.7.

    This was supposed to have been covered in class before assigning work on it. To study this on your own, try some online lessons.

    Note: If you look on your calculator and find the button marked "LN" (or "ln"), the "2nd" function should be something like "e^". Use this key to do the evaluation of 1 + e^(-3). The denominator should evaluate to approximately 1.049787.
