The formula a = p(1 + r)^2 is used to find the amount of money, a, in an account after p dollars have been invested in the account paying an annual interest rate, r, for 6 years. find the interest rate r if $1,500 grows to $2,535 in 6 years.

The interest rate after 6 years would be 5%.

Step-by-step explanation:

The proper equation for simple interest over time is A=P(1+rt), where 'A' is the amount of money after the principal amount 'P' has been invested at an interest rate 'r' over a certain amount of time 't'.  In order to find the interest rate 'r', we need to plug in the given values of the other variables.  So, $2535=$1500(1+6r).  To solve, we need to first divide both sides of the equation by 1500 to get 1.3 = 1 + 6r, then subtract 1 from both sides to get 0.3=6r, then divide both sides again by 6 in order to get the final answer of 0.05, which when multiplied by 100 gives us a percentage of 5%.  

answer: the answer is 30 miles per hour.

ft/s -> mphmph = ft/s 1.466667mph = 44 divided by 1.466667mph = 30.00000
