In a town whose population is 2600, a disease creates an epidemic. The number of people N infected t days after the disease has begun is given by the function N(t)- 2600 1+34 -0.6t. Complete parts a) through c) below a) How many are initially infected with the disease (t = 0)? (Round to the nearest whole number as needed.) b) Find the number infected after 2 days, 5 days, 8 days, 12 days, and 16 days. The number infected...

Let P(t) represent the number of people who, at time t, are infected with a certain disease. Let N denote the total number of people in the population. Assume that the spread of the disease can be modeled by the initial value problem: dP/dt = k(N − P)P, P(0) = P0. At time t = 0, when 100,000 member of a population of 500,000 are known to be infected, medical authorities intervene with medical treatment. As a consequence of this...

In a population of 300,000 people, 60,000 are infected with a virus. After a person becomes infected and then recovers, the person is immune (cannot become infected again). Of the people who are infected, 3% will die each year and the others will recover. Of the people who have never been infected, 40% will become infected each year. How many people will be infected in 4 years?

1. Assume a disease has a probability of infecting each individual in a population with truly random mixing with a daily value of p = 0.15. a. Produce two graphs: the first showing the time-course of the cumulative probability of being healthy and the second the cumulative probability of being diseased for 20 days. b. What is the cumulative probability of still being healthy at t = 10 days?c. If there are 1000 people in the population, estimate how many...

1. The number of people infected by a disease is being studied. Starting with a single patient, the number infected was shown to double every 5 days. Prove that the function N(t) = 24 can be used to model this behavior, in t days. N(0)= N(5)= N(10) N(15)= 2. Now, suppose the number infected doubles every 4 days. Which of these functions can be used to model N(t)? a) N(t) = 24 NO N(4)= N(8)= b) N(t) = 21/4+ N(0)...

In tracking the propagation of a disease, a population can be divided into 3 groups: the portion that is susceptible, S(C), the portion that is infected, Ft), and the portion that is recovering, R(t). Each of these will change according to a differential equation: R'= so that the portion of the population that is infected is increasing in proportion to the number of people that contract the disease, and decreasing as a proportion of the infected people who recover. If...
