Find the minimum and maximum of f(x, y, z) = y + 4z subject to two constraints, 2x + z = 4 and x2 + y2 = 1. g
yuradex [85]
L(x,y,z,\lambda_1,\lambda_2)=y+4z+\lambda_1(2x+z-4)+\lambda_2(x^2+y^2-1)

L_x=2\lambda_1+2\lambda_2 x=0\implies\lambda_1+\lambda_2x=0
L_y=1+2\lambda_2y=0
L_z=4+\lambda_1=0\implies\lambda_1=-4
L_{\lambda_1}=2x+z-4=0
L_{\lambda_2}=x^2+y^2-1=0

\lambda_1=-4\implies \lambda_2x=4\implies\lambda_2=\dfrac4x
1+2\lambda_2y=0\implies\lambda_2y=-\dfrac12\implies8y=-x

x^2+y^2=1\implies (-8y)^2+y^2=65y^2=1\implies y=\pm\dfrac1{\sqrt{65}}
y=\pm\dfrac1{\sqrt{65}}\implies x=\mp\dfrac8{\sqrt{65}}
2x+z=4\implies z=4\pm\dfrac{16}{\sqrt{65}}

We have two critical points to consider: \left(-\dfrac8{\sqrt{65}},\dfrac1{\sqrt{65}},4+\dfrac{16}{\sqrt{65}}\right) and \left(\dfrac8{\sqrt{65}},-\dfrac1{\sqrt{65}},4-\dfrac{16}{\sqrt{65}}\right).

At these points, we respectively have a maximum of 16+\sqrt{65} and a minimum of 16-\sqrt{65}.

the perimeter of a rectangular field is 326 yards. if the width of the field is 75 yards, what is its length?
just olya [345]
Perimeter = (2*length) + (2*width)
326 = (2*length) + (2*75)
326 - 150 = 2*length
2*length = 176
length = 176 / 2
length = 88
