To find: the solution of the system.

Answer to Problem 38RE
The system has no solution
Explanation of Solution
Given:
Calculation:
Let's begin by labeling our three equations.
First use Operation
This simplifies to
Our new system, with the new Equation
Now, make substitutions to solve for
It seems that the solution to the system is found. Let's check the solution
This is a false equation, since
All three of the original equations are simply lines (they have only
Note that Equation
Conclusion: Therefore, the system has no solution

- The spread of an infectious disease is often modeled using the following autonomous differential equation: dI - - BI(N − I) − MI, dt where I is the number of infected people, N is the total size of the population being modeled, ẞ is a constant determining the rate of transmission, and μ is the rate at which people recover from infection. Close a) (5 points) Suppose ẞ = 0.01, N = 1000, and µ = 2. Find all equilibria. b) (5 points) For the equilbria in part a), determine whether each is stable or unstable. c) (3 points) Suppose ƒ(I) = d. Draw a phase plot of f against I. (You can use Wolfram Alpha or Desmos to plot the function, or draw the dt function by hand.) Identify the equilibria as stable or unstable in the graph. d) (2 points) Explain the biological meaning of these equilibria being stable or unstable.arrow_forwardFind the indefinite integral.
