Find the relative maximum and minimum values. f(x.y)-20xy - x3- 10y Select the correct choice below and, if necessary, fill in the answer boxes to complete your choice. A. The function has a relative maximum value of f(x,y) = | | at (x,y)= (Simplify your answers. Type exact answers. Type an ordered pair in the second answer box.) O B. The function has no relative maximum value. Select the correct choice below and, if necessary, fill in the answer boxes to complete your choice. O A. The function has a relative minimum value of f(x,y): | at (x,y)= (Simplify your answers. Type exact answers. Type an ordered pair in the second answer box.) O B. The function has no relative minimum value. A company produces two types of solar panels per year: x thousand of type A and y thousand of type B. The revenue and cost equations, in millions of dollars, for the year are given as follows R(xy) 6x+ 8y C(x,y) = x2-4xy + 6y + 26x-64y-5 Determine how many of each type of solar panel should be produced per year to maximize profit. The company will achieve a maximum profit by selling solar panels of type A and selling solar panels of type B The maximum profit is s million
