Question 28

The rate at which a chemical residue accumulates in a filtration system, $R\,$ milligrams per hour, is modeled by the equation:

\frac{(5\sqrt{t} - 2)(3t + 1)}{3\sqrt{t}}, \quad t > 0

where $t\,$ is the time in hours since the filter was installed. Determine the general expression for the total mass of residue, $M (t)$ , in the system, giving your answer in simplest form.
