Let a and y be two positive numbers such that y | 2z = 30. Find the z and y values that maximize (y + 2)z. Solve the equation y + 2z - 30 for y: The feedback must read "The variables found in your answer were: [X]" otherwise your grade will be 0 for this part. The quantity to be maximized is Q(x, y) = (y + 2)&. Write this quantity only in terms of c: Q(z) = The feedback must read "The variables found in your answer were: [X otherwise your grade will be 0 for this part Find the derivative of Q (1) Q'(I)Find the derivative of Q (z): Q' (= = The feedback must read "The variables found in your answer were otherwise your grade will be 0 for this part. The values of T and y that maximize (y + 2) are: Check
