Given a two-dimensional array named scores with double type elements, write the embedded loop to navigate this array and multiply each element in the array by 10, and put the embedded loop inside a method named increase , and the only parameter of this method is a double type two-dimensional array. This method increase should have void as its return type.

Required:
Write the one line of code to invoke the increase method inside main. Do you need to receive the return value of increase with a local variable, why or why not?

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?
