Find all points on the portion of the plane x+y+z=5 in the first octant at which f(x, y, z) = xy2z2 has a maximum value.
irina1246 [14]
Lagrange multipliers:

L(x,y,z,\lambda)=xy^2z^2+\lambda(x+y+z-5)

L_x=y^2z^2+\lambda=0
L_y=2xyz^2+\lambda=0
L_z=2xy^2z+\lambda=0
L_\lambda=x+y+z-5=0

\lambda=-y^2z^2=-2xyz^2=-2xy^2z

-y^2z^2=-2xyz^2\implies y=2x (if y,z\neq0)

-y^2z^2=-2xy^2z\implies z=2x (if y,z\neq0)

-2xyz^2=-2xy^2z\implies z=y (if x,y,z\neq0)

In the first octant, we assume x,y,z>0, so we can ignore the caveats above. Now,

x+y+z=5\iff x+2x+2x=5x=5\implies x=1\implies y=z=2

so that the only critical point in the region of interest is (1, 2, 2), for which we get a maximum value of f(1,2,2)=16.

We also need to check the boundary of the region, i.e. the intersection of x+y+z=5 with the three coordinate axes. But in each case, we would end up setting at least one of the variables to 0, which would force f(x,y,z)=0, so the point we found is the only extremum.

Five ticets to a baseball game cost 60$. How much do 2 ticets cost
Leno4ka [110]

Answer:

$24

Step-by-step explanation:

Since you know 5 tickets equal to $60, and you want to find the cost of one ticket, you would divide 60 by 5. 60/5=12. So each ticket costs 12 dollars. But you want to find the cost of two. So multiply $12 by two to get $24 dollars per two tickets.

Help I will give brainiest​
sdas [7]

Answer:

1.  V = 94 meters cubed

2. V = 8 feet cubed

3.  V = 57 inches cubed

Step-by-step explanation:

The volume of a cone is 1/3 the volume of a cylinder. So all you need to do is plug the numbers into the formula for the volume of a cylinder and then you have the answer.

The formula for a cylinder is V= (3.14 or pi) * radius squared * height

The formula for a cone is V= (3.14 or pi) * radius squared * height * 1/3

So here you go.....

1. V= 3.14 x 9 x 10 x 1/3                V = 94 meters cubed

2. V= 3.14 x 4 x 2 x 1/3                   V = 8 feet cubed

3. V = 3.14 x 9 x 6 x 1/3                  V = 57 inches cubed

Please give me brainiest!
