Starting with a context diagram, draw as many nested DFDs as you consider necessary to represent all the details of your times portal system
described in the following narrative. You must draw at least a context and
level-1 DFD. In drawing these diagrams, if you discover that the narrative is
incomplete, make up reasonable explanations to complete the story.

It is not a good idea in a cover letter to mention another person whom the employer knows.

Determine whether the following careers would require training or college.

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?
