Question
![Gonorrhea is spread by sexual contact, takes 3 to 7 days to incubate, and can be treated with antibiotics. There is no evidence that a person ever develops
immunity. One model proposed for the rate of change in the number of men infected by this disease is
dy
ay + b(f-y)Y, where y is the fraction of men infected, f
di
is the fraction of men who are promiscuous, Y is the fraction of women infected, and a and b are appropriate constants
Answer parts (a) and (b) below
(a) Assume a1, b 1, and f-0.5. Choose Y0.03, and solve for y using y=002 when t is 0 as an initial condition
y= 0015+0 05e1031
