Final answer:
To solve the nonlinear programming problem, find the critical points and evaluate the function at those points to find the maximum value.
Step-by-step explanation:
To solve the nonlinear programming problem max
6y≥400, we need to find the possible values of x and y that maximize the given function while satisfying the constraint.
Step 1: Rewrite the constraint inequality as 3x+6y-400≥0.
Step 2: Find the critical points by solving the system of equations formed by the gradient of the function and the constraint. In this case, the only possible solution is x* = 0 and y* = 20.
Step 3: Evaluate the function at the critical points to find the maximum value. In this case, the maximum value is 500 - 7(0)^2 - 6(20)^2 = 500 - 2400 = -1900.
