Vikentia [17]4 years ago
8 0
4x - 2 > 6
4x > 8
x > 2

x + 3 <= -6
x <= -9 

so answer in interval notation is  (-∞, -9] or (2, ∞)

Suppose a student carrying a flu virus returns to an isolated college campus of 5000 students. Determine a differential equation
zloy xaker [14]

Answer:

x(t) = 5000*( 1 - e^-kt)  

Step-by-step explanation:

Given:

- Total number of students n = 5000

Find:

Differential equation governing the number of students x(t) who have contracted the flu.

Solution:

- Number of non-affected students = (5000 - x)

Hence,

- Rate at which students are infected:

                             dx / dt = k*(5000 - x )

- separate variables:

                             dx / (5000 - x ) = k*dt

- Integrate both sides:

                             - Ln(5000 - x) = kt + C

- Evaluate C for x = 0 @ t = 0

                             - Ln(5000 - 0) = k*0 + C

                               C = - Ln(5000)

- The solution to ODE is:

                               Ln(5000 - x) = -k*t + Ln(5000)

                                5000 - x = 5000*e^-kt

                                 x(t) = 5000*( 1 - e^-kt)
