(a) Explanation From given, note that a = 0 , b = 3 and the density of the rod in g/cm is ρ ( x ) = ( 4 − x ) . That is, the value of x in the left end is 0 and in the right end is 3. In order to find the end where the rod is lightest and heaviest, substitute the values of a and b for x in ρ ( x ) = ( 4 − x ) . Substitute 0 for x in ρ ( x ) = ( 4 − x ) , ρ ( 0 ) = 4 − 0 = 4 That is, ρ ( 0 ) = 4 . (b) To determine To find: The density at the middle of the bar.

Question 1. (10 points) A researcher is studying tumours in mice. The growth rate for the volume of the tumour V(t) in cm³ is given by dV = 1.45V(2 In(V+1)). dt (a) (4 pts) Find all the equilibria and determine their stability using the stability condition. (b) (2 pts) Draw the phase plot f(V) versus V where f(V) = V'. You may find it helpful to use Desmos or Wolfram Alpha to plot the graph of f(V) versus V (both are free to use online), or you can plot it by hand if you like. On the plot identify each equilibrium as stable or unstable. (c) (4 pts) Draw direction arrows for the case where the tumour starts at size 3cm³ and for the case where the tumour starts at size 9cm³. Explain in biological terms what happens to the size of each of these tumours at time progresses.
