To match : the equation with the graph.

Answer to Problem 7E
Explanation of Solution
Given information :
The equation is
First write the equation in a standard form of hyperbola,
Because the
Since here
Vertices: because the
The vertices on the y -axis are
Now substitute
So vertices are
Foci: because the
So foci are
Now substitute
So, the foci are
Asymptote: for the positive
Now substitute
So asymptotes are
Use the above information together with some additional values which is show in table below
To sketch the graph,

- 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.
