An important application of compound interest involves amortized loans. Some common types of amortized loans are automobile loans, home mortgage loans, and business loans. Each loan payment consists of interest and repayment of principal. This breakdown is often developed in an amortization schedule. Interest is largest in the first period and declines over the life of the loan, while the principal repayment is smallest in the first period and it increases thereafter. Hide Feedback Correct Quantitative Problem: You need $11,000 to purchase a used car. Your wealthy uncle is willing to lend you the money as an amortized loan. He would like you to make annual payments for 4 years, with the first payment to be made one year from today. He requires a 7% annual return. a. What will be your annual loan payments? Do not round intermediate calculations. Round your answer to the nearest cent. $ b. How much of your first payment will be applied to interest and to principal repayment? Do not round intermediate calculations. Round your answers to the nearest cent. Interest: $ Principal repayment: $ Hide Feedback Incorrect Check My Work Feedback Review the definition for an amortized loan. Review the definition for the PV of an ordinary annuity and its equation. If using a financial calculator, be careful about the meaning of the negative sign and remember to include FV = 0 (or be sure to clear all registers before starting problem).

3. Consider a deterministic Turing machine ? = (Q, ?, ?, ?, q?, q_{accept}, q_{reject}) whose input alphabet is ? = {a, b, c}, whose tape alphabet is ? = {a, b, c, X, U}, and that has the following state diagram. As usual the accepting state is drawn as qA to simplify the picture. All transitions that are not shown move to the rejecting state, leaving whatever symbol that is visible unchanged, and moving the tape head right. That is, every missing transition has the form ?(q, ?) = (q_{reject}, ?, R). a/a, R b/b, R X/X, R X/X, L c/c, R a/X, L q_{a,1} q_{a,2} q_{a,3} a/X, R c/c, L X/X, R start q? qL a/a, L b/b, L b/X, R c/c, R c/c, L q_{b,1} q_{b,2} q_{b,3} c/c, R b/X, L X/X, R qc a/a, R X/X, R X/X, L b/b, R U/U, L qA (a) Show the sequence of configurations that M reaches when it is executed on the input abcab.

Question 3: As will be discussed in future lectures, the volume rate of flow, Q, through a pipe can be determined by means of a flow nozzle located in the pipe as illustrated in the figure below. The nozzle creates a pressure drop, pA - pB, along the pipe which is related to the flow through the equation Q = K?(pA - pB), where K is a constant depending on the pipe and nozzle size. The pressure drop is frequently measured with a differential U-tube manometer of the type illustrated in the figure. If the specific weight of a fluid is defined as: ? = ?g, where ? is the fluid density and g the acceleration due to gravity: a) Determine an equation for pA - pB in terms of the specific weight of the flowing fluid, ?1, the specific weight of the gage fluid, ?2, and the various heights indicated. b) For ?1 = 9.80 kN/m3, ?2 = 15.6 kN/m3, and h2 = 0.5 m, what is the value of the pressure drop, pA - pB?
