Assume that you chose an 80% LTV mortgage of $450,000 with an interest rate of 8% over 30 years. However, after 10 years you are thinking about refinancing for $5,000. You will only be in the home for another 5 years. The new loan would be an ARM. Interest rates on 20-year ARMS are currently 6%. Interest rates are expected to increase to 7% in years 2 and 3 and then to 8% in years 4 and 5. - Find the return on your $5,000 refinancing cost. Should you refinance?

5. (3 pts) In class we stated that free-particles can be described as wave-packets, which have the time-dependent wave-function $\Psi(x, t) = \frac{1}{2\pi} \int_{-\infty}^{\infty} \phi(k)e^{ikx}e^{-i\hbar k^2 t/(2m)}dk$ Show that this does solve the time-dependent Schrödinger equation for a free particle.
5. [15 pts] Consider an array A = {23, 17, 10, 3, 9, 5} which is a maxheap. Using tree diagrams, illustrate the operation of Heapsort on maxheap A by following the code below: while (N > 1) { Exchange (A, 1, N--); sink(A, 1, N); }
