The insertions in red-black trees cost upto 2 rotations (if uncle is black) and upto O(log n) color changes (if uncle is red). Show that amortized color updates per insertion is O(1). (Hint: to develop an appropriate potential function try to see what is decreasing in the structure when we push the red-conflict upwards in case 1.)

Compute the duration of a bond with a face value of $1,000, a coupon rate of 7% (coupon is paid annually) and a maturity of 10 years as the interest rate (or yield to maturity) on the bond changes from 2% to 12% (consider increments of 1% - so you need to compute the duration for various yields to maturity 2%, 3%, …, 12%) . What happens to duration as the interest rate increases?

Refer to the reaction 2Mg + O2---> 2MgO

starting amounts 1.25mg 2Mg, and 25g of O2. What are the changes that occur in this reaction as its happening? Complete an ice table using the starting amounts and referring to the reaction above.

*I have no idea how to do these, in the words of Micheal Scott, "Why don't you explain this to me like I'm 5 years old."*

Explain the Federal Open Market Committee’s choice to lower the Federal Funds Rate and how it impacts the economy. Describe how this action impacts bank reserves, how this changes the loanable funds market (be sure to mention interest rate and lending levels and use a supply and demand model if its helpful), and business and consumer borrowing and spending. You can assume that leakages are minimal.

Suppose the economy is initially at a long-run equilibrium. Then the central bank increases the money supply. Assuming any resulting inflation is unexpected, explain any changes in GDP, unemployment, and inflation in the short-run that are caused by the monetary expansion. Explain your conclusions using three diagrams: (i) one for the IS-LM model, (ii) one for the AD-AS model, and (iii) one for the Phillips curve.

Consider a four-year project with the following information: initial fixed asset investment = $490682; straight-line depreciation to zero over the four-year life; zero salvage value; price = $34; variable costs = $24; fixed costs = $196864; quantity sold = 79583 units; tax rate = 32 percent. Calculate the sensitivity of the OCF to changes in the quantity sold.

Compute the total quantity of heat (both in Kcal and J) required to raise the temperature of 1.00 kg of ice at -10.0 degrees C to 1.00 kg of steam at 110.0 degrees C. Assume no loss of mass or heat in this process. Note that this will requires several computations that must be completely added up, and you must include all phase changes and use the correct specific heats.
