A rabbit population satis es the logistic equation
dy
dt = 2x10^-7y(10^6- y);
where t is the time measured in months. The population is suddenly reduced to
40% of its steady state size by myxamatosis. If the myxamatosis then has no further effeect, how large is the population 8 months later? How long will it take
for the population to build up again to 90% of its steady state size?

thank you!

your equation is much too ambiguous .
How are x and y defined?
Is the exponent of 10 equal to -7 or is is it 10^(-7y) ?
Is that (10^6) - y , the way you typed it, or is it
10^(6-y)

sorry,
its 10 to the exponent -7 then y
and then (10 to the exponent 6 take y)
