What are the solutions for x when y is equal to 0 in the following quadraticfunction? у = х^2 + 16х + 64оа) х = 0ов) х = 8oc) x = -8 od) х = 0 or x = 8oe) х = 0 or x = -8i did not mean to mark this under computer, i don't know how to fix it. ugh.

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?
