A rectangular storage container with an open top is to have avolume
IRINA_888 [86]

Answer:

Dimensions of the container:

x = 3 m

y = 6 m

h = 1.1 m

C(min) = 270 $

Step-by-step explanation:

Volume of storage container

V = 20 m³

Let  "y" be the length    and  "x" the width   then y = 2*x

V = x*y*h    ⇒  V = 2*x²*h      ⇒   20 = 2*x²+h      ⇒  h  =  10/ x²

Costs:

Total cost = cost of base  ( 5*2*x² )  + cost of side with base x  ( 2*9*x*h) +

cost of side witn base y =2x   (2*9*2x*h)

C(t)  = 10*x²  +  18*x*h  +  36*x*h

C(x)  = 10x²  + 54*x*10/x²      ⇒  C(x)  10*x²   +  540 /x

Taking derivatives on both sides of the equation we get:

C´(x)  =  20*x  -  540/x²

C´(x)  =  0        ⇒  20*x  -  540/x²  =  0   ⇒  2x  - 54/x²   = 0

2x³ - 54  = 0

x³  = 27       x  =  3 m

Then  y  =  2*x    ⇒ y = 2*3   y = 6     and  h  =  10 / x²       h  = 1.1 m

And the minimum cost is

C (min)  =  10*x²  +  540/x     ⇒      C (min)  =  90 + 180

C(min) = 270 $

X + 11 &lt; 6 <br> Solve and graph on a number line
Drupady [299]

Answer & Step-by-step explanation:

So I can't exactly graph exactly, but I'll try...

To solve:

x+11<6  Subtract 11 on both sides.

x<-5

To graph:

<-------|---------o---------|-------->

        -6        -5         -4

(The bolded part of the line is the side you shade the graph on. In case you can't see it, you have to shade the left side of the open circle.)

Hope this helps! Have an awesome day ( • ω • )^
