Hiring
Given:
Monthly average sales are
For one additional salesperson hired the average monthly sales drop by
Concepts Used:
Determining a linear relationship using rate of change and one point.
Total monthly sales is the number of salespersons working times the average monthly sales.
Graphing a quadratic polynomial function and finding its extremum.
Calculations:
Determine the relation between the average monthly sales for each salesperson
Note that the new number of working salespersons will be:
Calculate the total monthly sales.
The total monthly sales
The total monthly sales 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.
