Question 1163396
A radioactive substance decays so that after t years, the amount remaining,
expressed as a percent of the original amount, is {{{A(t) = 100(1.5)^(-t)}}}
Determine the rate of decay after 2 years. Round to 2 decimal places.
:
t = 2
Put this in your calc 100(1.5)^(-2)
44.44 % remain after 2 years
