In this example we will apply the equations for constant angular acceleration to the simple case of a rotating bicycle wheel. The angular velocity of the rear wheel of a stationary exercise bike is ω0=4.00rad/s at time t=0, and its angular acceleration is constant and equal to α=2.45rad/s2. A particular spoke coincides with the +x axis at time t=0 (Figure 1). What angle does this spoke make with the +x axis at time t=3.00s? What is the wheel's angular velocity at this time? part A: How much longer will it take before the reference spoke is once again aligned with the +x axis? Part B: What will the angular speed of the wheel be at this time?

Higher courts are reluctant to review a lower court's factual findings. Should this be so? Would appeals be fairer if appellate courts reviewed everything?

The insurance company where you work is planning to raise all premiums for health-care coverage. Your boss has asked you to read a draft of her letter to customers annousing the new, higher rates. The first two paragraphs discuss some exciting medical advances and the expanded coverage offered by your company. Only in the final paragraph do customers learn that they will have to pay more for coverage starting next year. What are the ethical implications of this draft? What changes would you suggest (in detail), and why?

Handi Inc., a cell phone manufacturer, procures a standard display from LCD Inc. via an options contract. At the start of quarter 1 (Q1), Handi pays LCD $4.00 per option. At that time, Handi’s forecast of demand in Q2 is normally distributed with a mean of 30,000 and a standard deviation of 9,000. At the start of Q2, Handi learns exact demand for Q2 and then exercises options at the fee of $2.70 per option, (for every exercised option, LCD delivers one display to Handi). Assume Handi starts Q2 with no display inventory and displays owned at the end of Q2 are worthless. Should Handi’s demand in Q2 be larger than the number of options held, Handi purchases additional displays on the spot market for $8.00 per unit. For example, suppose Handi purchases 37,000 options at the start of Q1, but at the start of Q2 Handi realizes that demand will be 40,000 units. Then Handi exercises all of its options and purchases 6,000 additional units on the spot market. If, on the other hand, Handi realizes demand is only 35,000 units, then Handi merely exercises 35,000 options.

a. Suppose Handi purchases 37,000 options. What is the expected number of options that Handi will exercise?

b. Suppose Handi purchases 37,000 options. What is the expected number of displays Handi will buy on the spot market?

c. Suppose Handi purchases 37,000 options. What is Handi’s expected total procurement cost?

d. How many options should Handi purchase from LCD?

e. What is Handi’s expected total procurement cost given the number of purchased options from part d?

Let P_Sand P_Drepresent the prices charged for each standard golf bag and deluxe golf bag respectively. Assume that “S” and “D” are demands for standard and deluxe bags respectively.

S = 2250 – 15P_S                                                                                                                                                                    (8.1)

D = 1500 – 5P_D                                                                                                                                                                      (8.2)

Revenue generated from the sale of S number of standard bags is P_S*S. Cost per unit production is $70 and the cost for producing S number of standard bags is 70*S.

So the profit for producing and selling S number of standard bags = revenue – cost = P_SS – 70S                            (8.3)

By rearranging 8.1 we get                                  

15P_S= 2250 – S or

                                    P_S= 2250/15 – S/15 or

                                    P_S= 150 – S/15                                                                                                                                                                     (8.3a)

Substituting the value of P_Sfrom 8.3a in 8.3 we get the profit contribution of the standard bag:

                                    (150 –S/15)S – 70S = 150S – S²/15 – 70S = 80S – S²/15                                                                                 (8.4)

Revenue generated from the sale of D number of deluxe bags is P_D*D. Cost per unit production is $150 and the cost for producing D number of deluxe bags is 150*D.

So the profit for producing and selling D number of deluxe bags = revenue – cost = P_DD – 150D                           (8.4a)

By rearranging 8.2 we get                                  

5P_D= 1500 – D or

                                    P_D= 1500/5 – D/5 or

                                    P_D= 300 – D/5                                                                                                                                                                       (8.4b)

Substituting the value of P_Dfrom 8.4b in 8.4a we get the profit contribution of the deluxe bags:

                                    (300 -D/5)D – 150D = 300D – D²/5 – 150D = 150D – D²/5                                                                          (8.4c)

By adding 8.4 and 8.4c we get the total profit contribution for selling S standard bags and D deluxe bags.

                                    Total profit contribution = 80S –S²/15 + 150D – D²/5                                                                                 (8.5)

Homework assignment:

Reconstruct new objective function for 8.5 by changing “15P_S” to “8P_S” in 8.1, “5P_D” to “10P_D” in 8.2, cost per unit standard bagfrom 70 to 91 and cost per unit deluxe bag from 150 to 125. Keep other parameter values unchanged. Use up to 2 decimal points accuracy. Substitute the new expression for 8.5 in the excel solver workbook as explained in the class and solve for the optimal combination values for S and D..Instructor will not accept any homework late or submitted outside the class. Make sure you submit the results (just one page excel printout). Write/type your full name (first name first) in upper case, last 4 of your student ID, and, your new objective function expression (like equation 8.5 above) on the printout. Use S and D instead of b15 or c15 in the formulation. If you fail to follow the instructions, you will lose points.

In C++

1. Test Scores #1

Write a program that dynamically allocates a built-in array large enough to hold a user-defined number of test scores. (Ask the user how many grades will be entered and use a dynamic array to store the numbers.) Once all the scores are entered, the array should be passed to a function that calculates the average score. The program should display the scores and average. Use pointer notation rather than array notation whenever possible. (Input Validation: Do not accept negative numbers for test scores.) Make it a class, call it something like gradeholder. You will need a destructor because you are using dynamic arrays.
