5) The function A(x) = A₂e-0.0077x models the amount in pounds of a particular radioactive material stored in a concrete vault, where x is the number of years since the material was put into the vault. If 700 pounds of the material are initially put into the vault, how many pounds will be left after 32 years? 6) Suppose that you have $6000 to invest. Which investment yields the greater return over 8 years: 7.15% compounded monthly or 7.15% compounded quarterly?
