Answer:

After 80 years 432 pounds of radioactive element will be remaining.

Step-by-step explanation:

A function A_{t}=A_{0}e^{-0.0077x} models the amount of a radioactive material.

Here x = number of years taken for decay.

If A_{t}=432 pound and A_{0}=800 pound, then we have to calculate the time for decay.

A_{t}=A_{0}e^{-0.0077x}

432=800e^{-0.0077x}

e^{-0.0077x}=\frac{432}{800}

Take log on both the sides of the equation

ln(e^{-0.0077x})=ln(\frac{432}{800} )

-0.0077x = ln(0.54)

-0.0077x = -0.616186

x = \frac{0.616186}{0.0077}

x = 80.02 years

Therefore, After 80 years 432 pounds of radioactive element will be remaining.
