Peter's chickens got the bird flu and he is rying to stop the epidemic. He knows that the function f(t) = 300 / ( 15 - 20e^(-0.07t) ) describes the number of his chickens who are sick t weeks after the initial outbreak. (a) How many chickens became sick when the flu epidemic has began? I got -60 for my answer, which doesn't seem right (b) In how many weeks will 100 chickens be sick? i got roughly 7.3 weeks (c) What is the maximum number of chickens that will become ill?

anonymous
  • anonymous
haha, i can't figure it out. that's the point. i just assumed t would be 0, and when i plugged that in, i got a negative number

uhm dont worry about it. our prof just told us we don't have to do part a. could you maybe help me with part c?
NotTim
  • NotTim
eh...this doesn't look parabolic...is it? i ahvent done the math myself.
NotTim
  • NotTim
but if it is, then it is at the midpoint
anonymous
  • anonymous
well the prof said to not do part a
NotTim
  • NotTim
oh, talking about c there. I think a is 0...
NotTim
  • NotTim
..unless the 'parabola' has shifted...

it's okay, we don't need to wrry about it

for part c, i find the derivative and set it to 0 right?
NotTim
  • NotTim

NotTim
  • NotTim

NotTim
  • NotTim
