The population P (in thousands) of a colony of rabbits at time (t) years is given by P(t) = 5+ ae-bt. t>0 where a and b are positive constants. If it is given that the initial population is 10, 000 rabbits and one year later this population has reduced by 1,000, find the following; (a) The values of a and b. (b) The time (to 2 decimal places) when the population becomes two-thirds of the initial popu- lation. (c) The time when there is no change in the rabbit population as time changes. Explain your answer.

Question
The population P (in thousands) of a colony of rabbits at time (t) years is given by
P(t) = 5+ ae-bt
t20
where a and b are positive constants. If it is given that the initial population is 10, 000 rabbits and
one year later this population has reduced by 1, 000, find the following;
(a) The values of a and b.
(b) The time (to 2 decimal places) when the population becomes two-thirds of the initial popu-
lation.
(c) The time when there is no change in the rabbit population as time changes. Explain your answer.
