Question 263
a.

The rate of mass accumulation in a sediment trap is modeled by the function R(t)=12t4t+1R(t) = \dfrac{12t}{\sqrt{4t+1}}R(t)=4t+1​12t​, where R R\,R is the rate in grams per day and t t\,t is the time in days since the start of the study. Using a suitable substitution, find the exact mass accumulated during the first 2 days.
