What is the most useful source of information on customers generated by any company? Identify all the possible data available on that source.

discuss one of the services Windows offers. Give a quick description of the service, how to configure and enable it, whether the system uses it all the time, or just when you turn it on, and what your opinion is of the service. Does it do everything it needs to do for the user? What about ease of use?

discusses stopping, starting and restarting services. How often should you, as the administrator of your machine, have to do that? Should the operating system handle these tasks? Should this all be automated? When changing the attribute of the service, how does it affect other services? Discuss this and any other facts about these tasks in your homework.

1. Explain how the business planning process is one of revision. Explain two clear examples of your own (not those in the textbook) showing how your calculations in the financial section of the business plan, may force you to go back and change elements in previous sections of the plan.

Programming Task 1:

Please use the following framework to implement a class for partially filled arrays.

class PartiallyFilledArray

{

     double[] content;          // content of the array

     int size;                  // actual size of the array

     // creating an array whose physical size is 100

     PartiallyFilledArray()

     {

           // your implementation

     }

     // creating an array whose physical size is given by maxSize

     PartiallyFilledArray(final int maxSize)

     {

           // your implementation

     }

     // insertion

     boolean insert(_____________________)

     {

           // your implementation

     }

     // deletion

     boolean delete(_____________________)

     {

           // your implementation

     }

     // displaying all elements

     void display()

     {

           // your implementation

     }

}

Programming Task 2:

Please use the above class to create an empty partially filled array whose maximum size is 2000. (1) Consecutively add 20 different random integer values ranging from -100 to 100 to the array and display the content. (2) Delete the first 3 elements and display the content. Notice that you should not directly use the internal data field of PartiallyFilledArray in your test code.

A buffer solution contains 0.72 mol of hydrosulfuric acid (H2S) and 0.70 mol of sodium hydrogen sulfide (NaHS) in 8.60 L. The Ka of hydrosulfuric acid (H2S) is Ka = 9.5e-08.

(a) What is the pH of this buffer?

pH =

(b) What is the pH of the buffer after the addition of 0.17 mol of NaOH? (assume no volume change)

pH =

(c) What is the pH of the original buffer after the addition of 0.53 mol of HI? (assume no volume change)

pH =
