Answer the problem below or in the description:
The rate of decay of radium is said to be proportional to the amount of radium
present. If the half-life of radium is 1700 years and there are 400 grams on hand now. Given the exponential decay equation, y=Cekt, solve the following:
a.) What is the value of ek
b.) What equation best illustrates the problem?
c.) How much radium will be present in 845 years?
