A research lab has a 12 mg sample of a radioactive substance. The amount of the substance, A(t), left in the sample can be modelled by the half-life function A(t) = 12 on where t represents the time, in days, after the initial time. How much of the original sample will remain after 10 days, to the nearest tenth? (Record your answer in the numerical response box from left to right.) Answer:
