Answer:

8/3

hope this helps!!!

Step-by-step explanation:

1 3/5 = 8/5

1 1/5 = 6/5

8/5=6/5*1/2*h

6/10h=8/5

h=8/3

Answer: 2.7

Step-by-step explanation:

a = (bxh) ÷ 2

1.6 = (1.2xh) ÷ 2 set up equation

3.2 = 1.2 x h multiply both sides by 2

2.7 = h divide both sides by 1.2

Use Lagrange multipliers to minimize the function subject to the following two constraints. Assume that x, y, and z are nonnegat

Complete Question

The complete question is shown on the first uploaded image

Answer:

Option C is the correct option

Step-by-step explanation:

From the question we are told that

The equation is $f (x, y , z ) = x^2 +y^2 + z^2$

The constraint is $P(x, y , z) = x + y + z - 24 = 0$

Now using Lagrange multipliers we have that

$\lambda = \frac{ \delta f }{ \delta x } = 2 x$

$\lambda = \frac{ \delta f }{ \delta y } = y$

$\lambda = \frac{ \delta f }{ \delta z } = 2 z$

=> $x = \frac{ \lambda }{2}$

$y = \frac{ \lambda }{2}$

$z = \frac{ \lambda }{2}$

From the constraint we have

$\frac{\lambda }{2} + \frac{\lambda }{2} + \frac{\lambda }{2} = 24$

=> $\frac{3 \lambda }{2} = 24$

=> $\lambda = 16$

substituting for x, y, z

=> x = 8

=> y = 8

=> z = 8

Hence

$f (8, 8 , 8 ) = 8^2 +8^2 + 8^2$

$f (8, 8 , 8 ) = 192$
