Answer:

The greater than or equal to sign is:

>= or ≥.

Now let's solve for this <u>inequality</u>.

-8x + 5 ≥ -3

First, we need to get rid of any <u>constants</u>.

Get rid of a constant by performing the inverse operation of it, we always apply this to both sides of an inequality.

The inverse operation of addition (since it is a <u>positive</u> 5) is subtractions.

So, we subtract 5 from both sides;

-5         -5

Now we have:

-8x ≥ -8

Now, all we need to do is isolate x from it's co-efficient, 8.

To do that, we also utilize the inverse operation.

The inverse operation of multiplication (since -8 is being multiplied by x) is division, we apply this to both sides of this inequality.

So, we divide by -8 from both sides;

÷ -8 ÷ -8

And we'll end up with:

<u>x ≥ 1</u>, therefore the solution to this inequality is <u>1</u>.

Logan and his brother plan to make spherical glass ornaments to decorate their living room. Logan decides to completely fill the
mixer [17]
For this case the first thing you should do is find the volume of the sphere.
 We have then:
 V = (4/3) * (pi) * (r ^ 3)
 Where,
 r: sphere's radius
 Substituting values we have:
 V = (4/3) * (3.14) * ((3/2) ^ 3)
 V = 14.13 in ^ 3
 Answer:
 
The amount of glitter required to completely fill one glass ornament is:
 
V = 14.13 in ^ 3

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.
