«
The number of fish X in a small lake at time t months after a certain
instant, is modelled by the DE
dx
dt
= x(1 − kt),
where is a positive constant. We may assume that X can be treated as
a continuous variable.
It is estimated that there are 10 000 fish in the lake when t = 0 and
months later the number of fish returns back to 10 000.
(a) The value of the constant kis
three decimal places.)
