Ashley just invested $9900 in a mutual fund. If the fund's manager expects a growth rate of 6% each year, how long will it take for Ashley's investment to reach a value of $16000? How about a value of $25000? Express your answers in years.

step-by-step explanation:

assume that you have 3 different side lengths.   apply the pythagorean theorem here:   square each of the two shortest sides; call them a and b, so that their squares are a² and b².   also square the longest side, calling the result c².

now, if a² + b² = c² is true, the triangle is a right triangle; otherwise it is not a right triangle.
