Concept explainers
a.
To find: An expression for
The expression for concentration
Given information:
The amount of water added is
Formula used:
Concentration is equal to amount of acid over total volume
Calculations:.
Here total volume when
Concentration of acid is
So concentration
Hence expression for concentration
b.
To sketch : use a graph to determine amount of water should be added to get the solution is
Given information:
The concentration is
Concept used:
Take
Thus based on the graph amount of the water added to the concentration is
c.
To find : the amount of water should be added to get the solution is
The amount of water to get concentration
Given information:
The concentration is
Formula used:
Calculations:
Take
Substitute the value in to the equation:
Hence the amount of water to get concentration

- 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.
