A population of rabbits starts off at time = 0 with 225 rabbits and increases at a rate of r(t) rabbits per month, where t is in months.

A. What does the expression (24 integral 36)r(t)dt represent?

B. What does the expression 225 + (0 integral 18) r(t)dt represent?

C. Suppose you're told that 1/24(0 integral 24) r(t)dt=4.25. How many rabbits are there in the population after 2 years?

Could someone explain these to me please? Thanks

  1. A. the population growth during the 3rd year
    B. population after 18 months
    C. well, ∫[0,24] r(t) dt is the population, so this is the average population during the 1st two years.
