I WILL GIVE BRAINLIEST FOR HELP ON PARTS A, C, and D!!! Minimizing Surface Area: United Parcel Service has contracted you to design an open box with a square base that has a volume of 5000 cubic inches.
a) express the surface area S of the box as a function of x.
b) using a graphing utility, graph the function found in part a.
c) what is the minimum amount of cardboard that can be used to construct the box?
d) what are the dimensions of the box that minimize the surface area?
e) what might the UPS be interested in designing a box that minimizes surface area?

I mainly need help with parts a, c, and d. Thanks!

Based upon past experience, barry expects no overdrafts. he expects no 2nd copies of statements. barry estimates that he will use network atms about 5 times a month with either bank. barry decides in the end to choose eecu. assuming that both banks provide the necessary services equally well, and based upon the tables of fees given above, how much can barry reasonably expect to save annually by choosing eecu in this case over e-town bank? a. $72 b. $78 c. $144 d. $24

The table shows population statistics for the ages of best actor and best supporting actor winners at an awards ceremony. the distributions of the ages are approximately bell-shaped. compare the z-scores for the actors in the following situation. best actor best supporting actor muequals42.0 muequals49.0 sigmaequals7.3 sigmaequals15 in a particular year, the best actor was 59 years old and the best supporting actor was 45 years old. determine the z-scores for each. best actor: z equals best supporting actor: z equals (round to two decimal places as needed.) interpret the z-scores. the best actor was (more than 2 standard deviations above more than 1 standard deviation above less than 1 standard deviation above less than 2 standard deviations below) the mean, which (is not, is) unusual. the best supporting actor was (less than 1 standard deviation below more than 1 standard deviation above more than 2 standard deviations below more than 1 standard deviation below) the mean, which (is is not) unusual.

This is so hard and it’s for a test
