Answer to Problem 60E
The minimum weekly cost is
Explanation of Solution
Given cost is
Calculation::Given in the question that the weekly cost is
For any function
Critical points occur at
It gives the condition of maximum.
Thus, the minimum weekly cost is

Answer to Problem 60E
The minimum weekly cost is
Explanation of Solution
Given cost is
Calculation: Given in the question that the weekly cost is
If the formula changes to
Here equations changes only by a constant value. On repeat all the procedure as done in (a) ,the most economic quality is again
Thus, the minimum weekly cost 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.
