Homework Statement


dP/dt = (3000)/(1+0.25t)
This gives the rate population changes at
We also know P is 1000 when t is 0 (days)

The Attempt at a Solution


The anti derivative
12 000 x Ln(1 + 0.25t) + c
Do I just make this equation equal to one million?

the question says the bacteria will overrun the world if its population reaches one million. Its asking if the bacteria will reach that amount

you can find out integration constant (c) , by plugging in the the value of bacterias given at t=0 .

So c is 3000

Then find out what the question is asking for using c .

No, P=12 000 x Ln(1 + 0.25t) + c=1000 at t=0. What is the correct value of c?
