Chapter 8, Problem 18T

(a)

To determine

To calculate: The amount of plutonium-241 remaining after 4 years if the amount of plutonium-241 present in the given sample is determined by the function $f\left(x\right)=2.00e^{-0.053x}$.

(b)

To determine

To calculate: The amount of plutonium-241 remaining after 10 years if the amount of plutonium-241 present in the given sample is determined by the function $f\left(x\right)=2.00e^{-0.053x}$.

(c)

To determine

To calculate: The amount of plutonium-241 remaining after 20 years if the amount of plutonium-241 present in the given sample is determined by the function $f\left(x\right)=2.00e^{-0.053x}$.

(d)

To determine

To calculate: The initial amount of plutonium-241 present if the amount of plutonium-241 present in the given sample is determined by the function $f\left(x\right)=2.00e^{-0.053x}$.
