The annual growth rate for an investment that is growing continuously is given by r = 1/tIn(A/P) where P is the principle and A is the amount after t years.
An investment of $9000 with a certain computer company in 1995 grew to $250000 in 1998. Assuming the investment grew continuously, what was the annual growth rate?
-------------
r = 1/[3*ln(250000/9000)]
r = 1/[3*ln(27.78)]
r = 1/9.9729..
r = 0.1027...
r = 10.27%
