Final answer:
To maximize Q = xy, where x and y are positive numbers such that x + 3y² = 16, the objective function in terms of y is Q = (16 - 3y²)y.
Step-by-step explanation:
To maximize Q = xy, where x and y are positive numbers such that x + 3y² = 16, we need to express the objective function in terms of y.
First, rearrange the equation x + 3y² = 16 to solve for x: x = 16 - 3y².
Now substitute the expression for x in the objective function: Q = (16 - 3y²)y.
