Answer 2

do you know Q(t)

if you do just substitute it

Answer 3

No. Here's the problem:
A process creates a radioactive substance at the rate of 2 g/hr and the substance decays at a rate proportional to its mass, with constant of proportionality k=0.1(hr)^-1. If Q(t) is the mass of the substance at time t, find the limit of Q(t) as t approaches infinity.
