The rate of growth of a population of micro-organisms is modelled by the equation: dP/dt = 3t^2+6t, where P is the population size at time t hours. Given that P=100 at t=1, find P in terms of t.

First, we integrate the equation with respect to t to find an equation for P. dP/dt = 3t2 + 6t Then, P= integral (3t2 + 6t) dt Integrating gives P= t3+3t2+c, c ...
