Answer to Problem 89E
The center of the circle is
Explanation of Solution
Given information:
The equation
Formula used:
The standard form of the equation of the circle is
Calculation:
Consider the equation
Rewrite the equation as,
Recall that the standard form of the equation of the circle is
Compare,
Here,
Therefore, center of circle is
Now, on the Cartesian plane construct a circle with center at
The graph obtained is provided below,
Thus, the center of the circle is

- 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.
