Reference no: EM13167802

The function A=A0e^-0.00866x models the amount in pounds of a particular radioactive material remaining in a concrete vault, where x is the number of years since the material was put into the vault. If 200 pounds of the material are initially put into the vault, how many pounds will be left after 90 years?
