Suppose a student carrying a flu virus returns to an isolated college campus of 7000 students. Determine a differential equation
Alex73 [517]

Answer:

The differential equation is  \frac{dx(t)}{dt} = k   x(t) [7000 - x(t)]

Step-by-step explanation:

From the question we are told that

     The number of students are n =  7000

      The number of student that have contracted the flu is  x(t)

The number of student that don't have the flu is mathematically represented as

      z = 7000 - x(t)

The rate at which the disease spread is proportional to the number of interactions between students with the flu and students who have not yet contracted it, which can be mathematically represented as

         \frac{dx(t)}{dt} \ \ \ \alpha\ \ \   x(t) [7000 - x(t)]

=>     \frac{dx(t)}{dt} = k   x(t) [7000 - x(t)]
