I’m learning about data bases and I really need help to do this work it’s due in like 20 minutes

The concept of comes from the acknowledgment that data changes form and often gets copied, moved, and stored in many places. sensitive data often leaves the protection of application databases and ends up in e-mails, spreadsheets, and personal workstation files.

How many nibbles can be stored in a 16-bit word?

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?
