The rate of growth dP/dt of a population of bacteria is proportional to the square root of t, where P is the population size and t is the time in days (0 ≤ t ≤ 10) as shown below.

Explanation
Given that the rate of change is'
[tex]\frac{dp}{dt}=k\sqrt{t}[/tex]We can get the function of the population by integrating the above function
