Answer to Problem 39E
The simplified form of the expression is
Explanation of Solution
Given information:
The expression is
Formula used:
To add or subtract rational expression, first find the common denominator and then use the following property of fractions:
If denominators are not same the find least common denominator. The least common denominator is found factoring each denominator and taking the product of distinct factors, using the highest power that appears in any of the factors.
Calculation:
Consider the provided expression.
Recall that,
To add or subtract rational expression, first find the common denominator and then use the following property of fractions:
If denominators are not same then find least common denominator. The least common denominator is found factoring each denominator and taking the product of distinct factors, using the highest power that appears in any of the factors.
Re-write the given expression as:
Since denominators are not the same then find the least common denominator,
The least common denominator of
Add fractions,
Combine terms in numerator,
Factor out
Thus, the simplified form of the expression 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.
