Pythagorean theorem you times 40 by 2 then 9 by 2 then square root
1) Compound interest formula:
**<span>
**A = amount, P = principal amount, r = rate, n = # of times interest is compunded every year, t = time(in years)
2) Plug numbers in
</span>
3) Solve
A = 635.24458054
Hope this helped! Good Luck!
