To Calculate:
The dimensions of a rectangular painting.
The rectangular painting has width
Given:
The length of painting is
The wooden frame around the painting is
The area of the picture and frame combined is
Concepts Used:
The conversion factor
The area of a rectangle is the product of its length and width.
Calculations:
Let the width of the rectangle be
Draw a figure representing the given situation.
The outer rectangle formed after combining a frame around the picture which is
Only positive value of width makes sense so
The length is
Conclusion:
The rectangular painting has width

- 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.
