A personal phone directory contains room for first names and phone numbers for 30 people. assign names and phone numbers for the first 10 people. prompt the user for a name, and if the name is found in the list, display the corresponding phone number. if the name is not found in the list, prompt the user for a phone number, and add the new name and phone number to the list.

Think about a recent customer service experience - either positive or negative. write a brief summary of that experience. now think about those four characteristics we look for in customer service representatives. how did the representative in your example stack up? write down your answer and give specific examples.

The file sales data.xlsx contains monthly sales amounts for 40 sales regions. write a sub that uses a for loop to color the interior of every other row (rows 3, 5, etc.) gray. color only the data area, columns a to m. (check the file colors in excel.xlsm to find a nice color of gray.)

The volume v and paper surface area a of a conical paper cup are given by where r is the radius of the base of the cone and h is the height of the cone. a. by eliminating h, obtain the expression for a as a function of r and v. b. create a user-de ned function that accepts r as the only argument and computes a for a given value of v. declare v to be global within the function. c. for v ! 10 in.3 , use the function with the fminbnd function to compute the value of r that minimizes the area a. what is the corresponding value of the height h? investigate the sensitivity of the solution by plotting v versus r. how much can r vary about its optimal value before the area increases 10 percent above its minimum value?
