Tritium is a radioactive isotope of hydrogen that decays by about 5% per year. A large bottle of water that contained 450,000 tr
Basile [38]

Using an exponential function, it is found that the bottle contains 255,960 atoms of tritium after 11 years.

<h3>What is an exponential function?</h3>

A decaying exponential function is modeled by:

A(t) = A(0)(1 - r)^t

In which:

  • A(0) is the initial value.
  • r is the decay rate, as a decimal.

In this problem:

  • The bottle initially contained 450,000 tritium atoms, hence A(0) = 450000.
  • The amount decays by about 5% per year, hence r = 0.05.

Thus, the equation is given by:

A(t) = A(0)(1 - r)^t

A(t) = 450000(1 - 0.05)^t

A(t) = 450000(0.95)^t

After 11 years, the amount is given by:

A(11) = 450000(0.95)^{11} = 255960

The bottle contains 255,960 atoms of tritium after 11 years.
