And base length is
Formula used:
Volume
Surface area
Calculations:
The volume:
Then surface area:
Hence the expression for surface area
b.
To find : the length,width and height if the out side surface area is
If length
Given information:
The volume is equal to
And base length is
Formula used:
Volume
Surface area
Calculations:
Surface area :
Since length, height,width are positive values so take positive values.
For the length
For the length
So if length

- 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.
