Question
Use Lagrange multipliers to find the indicated extremum. Assume that x and y are positive. Minimize f(x, y) Vx? + y? Constraint: 10x + 20y – 10 = 0 Step 1 First note that f(x, y) is minimum when g(x, y) = x- + y is minimum. Hence, we will minimize g(x, y) subject to the constraint h(x, y) —D 10х + 20y — 10. Define a new function F as F(x, у, а) %3D д(х, у) — ah(x, у) x2 + y? - 1(10x + 20y – 10). Find the partial derivatives of F with respect to x, y, and 1. F, (x, v. A) F,(x, v.a) = 2x Fy (x, y, a 2у — x, Y, a) = - 10 10х +
