Consider the steady, incompressible blood flow through the following vascular network: 100 µm diameter which is 80 mm in length to the first branching point, which can be estimated as a standard tee (flow through run), the branch off the tee turns 45 degrees and undergoes a constriction to 65 µm diameter and the flow through run continues for another 80 mm. The velocity of the blood into the 100 µm diameter vessel is 100 mm/s and 20% of the mass flow rate exits via the branch.
a) What are the velocities of both the run and branch?
b) What is the change in pressure from the inlet to the end of the run?
c) What length would the branch need to be to achieve the same pressure drop?
d) What assumptions did you make in completing this problem.

You are responsible for managing a performance-based advertising
campaign for your company that provides Indian cuisine cooking
classes that cost $100 per student. You have a budget of $300 per
day. The search terms you decide to bid on are cooking classes and
Indian cooking classes. You initially allocate $200 per day to the
first campaign and $100 to the second. Over time you realise that
“cooking classes” generates on average 500 clicks per day resulting
in sales of $5000. “Indian cooking classes” generates on average
100 clicks resulting in sales of $3000. Which campaign would appear
to be the most effective? Calculate the CPC and ROI for each
campaign to justify your response. Feel free to use your computer
or a calculator to help you work out the answers.

First calculate the delta of the following option. Then use this delta to ESTIMATE the new price of a European call option if the stock price increases by $4. The option has the following the following initial parameters:
s0 = $40
k = $35
r = 10%
sigma = 20%
T = 0.75 years

Suppose you believe that Johnson Company's stock price is going to increase from its current level of $40 sometime during the next 5 months. For $400 you can buy a 5-month call option giving you the right to buy 100 shares at a price of $60 per share. If you buy this option for $500 and Johnson's stock price actually rises to $70, would you exercise your call option? AND what would be your pre-tax net profit or loss from holding this option?

The supply curve for rental cars in San Francisco is given by the equation Qs=100+8p. The demand curve for rental cars is given by the equation Qd=500-2P. P is the daily rental price, in dollars, and Q is the number of rentals per day.
a. Use algebra to determine the equilibrium price and quantity of rental cars in San Francisco. Show your work. Be sure to include the units of measurement in your answers.
b. Draw a graph of the market for rental cars. On your graph, clearly label the axes, the demand and supply curves, and the equilibrium price and quantity.

b. What would be the percentage change in the price of the bond implied by the duration approximation?
c. What would be the percentage change in the price of the bond implied by the duration plus convexity approximation?
d. Why does adding the convexity term to the approximation improve it?
