The rate of growth of the population N(t) of a new city t years after its incorporation is estimated to be
The rate of growth of the population N(t) of a new city t years after its incorporation is estimated to be dN/dt = 400 + 900√t where 0 ≤ t ≤ 9. If the population was 5,000 at the time of incorporation, find the population 9 years later. The population 9 years later will be _______ . (Round to the nearest integer as needed.)
