Answer :
This is the formula to find the amt. A of that radioactive substance after time t.
[tex]A_t=750e^{0.119t}[/tex]
We want to find out low long it will take for A to become half of its original amount.
We don't know the original amount, and the substance is not decaying at a constant rate (but rather an exponential one) so we can't answer that question.
Is there any information you forgot to give? Double check yourself.
