Question

(1 point) Redo problem 14 in section 4.7 of your textbook (page 215) but use the data below rather than the data in your textbook: Assume 10 people originally have the virus and that in early stages the number of people infected is increasing approximately exponentially, with a continuous growth rate of 1.32. Assume turther that in the long run, they estimate approximately 8500 people will be infected. (You may wish to sketch a graph of your logistic tunction P (a) What should we use for the parameters k and L? to help you understand this situation and answer the questions below.) 1.32 L8500 (b) Use the fact that when 0, we have P 10, to find C. C-(8500-10/10 (c) What is the value of P when the rate at which people are becoming infected peaks? When does this occur?

Explanation / Answer

a)

Given

k= growth rate = 1.32

L= carrying capacity = 8500

b)

C= (L- P0)/P0

= (8500 -10)/10

= 849

c)

P= L/2

= 8500/2

=4250

And

t= ln(C)/k

t= ln(849)/1.32

t=5.109
