hmm is this first order differential equations?
formula y= (y0*L)/[y0+(L-y0)e^-kt]
1.) when looking at a graph of a function, how do i estimate the value of k?
2.) suppose that the growth of a population y=y(t) is given by the logistic equation y= (1000)/(1+999e^-.9t)
when does the population reach 75% of the carrying capacity?
so far i have:
but what do i plug in for y?
3.)suppose that a population y(t) grows in accordance with the logistic model dy/dt= 50y-.0001y^2
what is the value of k?
for what value of y is the population growing most rapidly?
