Problem 2 (Calculating inverse Z-transforms [OWN 10.23]). Determine the inverse Z-transform for each of the following signals: (a) $X(z) = \frac{1 - \frac{1}{4}z^{-1}}{1 - \frac{1}{2}z^{-1} - \frac{1}{4}z^{-2}}$ with ROC $|z| < \frac{1}{2}$ (b) $X(z) = \frac{z^{-1} - \frac{1}{2}}{1 - \frac{1}{2}z^{-1} - \frac{1}{2}z^{-2}}$ with ROC $|z| < \frac{1}{2}$ (c) $X(z) = \frac{z^{-1} - \frac{1}{2}}{(1 - \frac{1}{2}z^{-1} - \frac{1}{2}z^{-2})^2}$ with ROC $|z| < \frac{1}{2}$

39. To start the engine, the starting motor rotates the crankshaft about a 3000 rpm b. 45,000 rpm c. 50 rpm d. 200 rpm 40. The overrunning clutch performs all the following EXCEPT transmits cranking torque to the engine b. damages the armature if it fails to lock c. prevents the engine from driving the pinion d. acts as a one-way clutch 41. The alternator produces an alternating current in its a. rotor field coil b. stator windings c. regulator d. load circuit 42. The purpose of the regulator is to a. prevent the alternator voltage from going too high b. allow the alternator to produce a high current c. keep alternator speed from going too high d. keep alternator voltage enough to charge the battery 43. The cause of no output from the alternator could be a. an open diode b. an open field winding c. an open stator winding d. all of the above 44.In the electronic ignition system, the primary circuit is opened and closed by a. a solenoid b. contact points c. a mechanical switch d. an electronic switch c. feeds 45.Ignition systems with electronic spark advance include and ECM that a. controls engine speed b. calculate spark advance information to a series of sensors d. controls centrifugal advance 46.

Suppose you are a freelance programmer who needs to decide which job to take each week. The set of possible jobs is divided into low-stress and high-stress ones. The basic question each week is whether to take on a low-stress job or a high-stress job. If you select a low-stress job in week i, you get a revenue of f > 0. If you select a high-stress job, you get a revenue of h > 0. The catch, however, is that in order to take on a high-stress job in week i, it is required that you take no job (of either type) in week i-1. You need a full week of prep time to get ready for the crushing stress level. On the other hand, you can take a low-stress job in week i even if you have done a job (of either type) in week i-1. Given a sequence of n weeks, a valid plan is specified by a choice of low-stress, high-stress, or none for each of the n weeks, with the property that if high-stress is chosen for week i > 1, then none has to be chosen for week i-1. It is okay to choose a high-stress job in week 1. The value of the plan is the sum of the revenue you get in each week: f if you choose low-stress in week i, h if you choose high-stress, and 0 if you choose none. The problem is to find a plan of maximum value given n > 0 and f, h, ..., hn > 0. For example, suppose n = 4 and the values of f and h are given by the following table: week | 1 | 2 | 3 | 4 | -------|---|---|---|---| f | 0 | 0 | 10| 10| h | 50| 0 | 0 | 0 | Then the plan of maximum value would be to choose no job in week 1, a high-stress job in week 2, and low-stress jobs in weeks 3 and 4. The value of this plan would be 0 + 50 + 10 + 10 = 70. a) Does the following algorithm correctly solve this problem? Justify your answer. ``` for i = 1 to n do if hi+1 > hi then Output choose no job in week i Output choose a high-stress job in week i+1 Continue with iteration i+2 else Output choose a low-stress job in week i Continue with iteration i+1 ``` b) Give an algorithm that outputs the value of the optimal plan. Your algorithm should run in time O(n). Prove the correctness of your algorithm and analyze its running time.

Using babynames in the tidyverse in R, use summarize, n_distinct, group_by, and arrange to find the ten years with the most distinct names given to five or more children. Then, display the top ten years in a bar chart with the years along the x-axis and the number of distinct names along the y-axis. Display the years in order from highest to lowest number of distinct names. Add appropriate titles and labels. Note: do not count a name twice if it occurs for both boys and girls in a given year.
