Find the relative maximum and minimum values. f(x.y) = ex - 5y2+12 Select the correct choice below and, if necessary, fill in the answer boxes to complete your choice 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(X.y) =6x + 7y C(x.y) = x- -4xy + 9y+20x - 81y -8 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 5000 solar panels of type A and selling 6000 solar panels of type B. The maximum profit is $ |million
