The management of a department store has decided to enclose an 800 sq. ft.area outside the building for displaying potted plants
Sliva [168]

Answer:

Dimension of the enclosure is 56.56 ft * 14.14 ft

Step-by-step explanation:

Given -

Let us suppose that x is the length of steel fence and y is the length of one side of pine boards

 

We know that - xy = 800.

y = 800/x

 

Let us say that  C is the cost of fence

 

                = 3x + 6(2y) = 3x + 12y = 3x + 12(800/x)

 

C = 3x + 9600x-1, x > 0

 

C' = 3 - 9600x-2 = (3x2-9600)/x2

 

C' = 0 when 3x2 = 9600

 

                  x2 = 3200

 

                  x = √3200 ft ≈ 56.56 ft

So, the cost is minimized when x ≈ 56.56 ft and y = 800/x ≈ 14.14 ft

I think, the answer will be -7

We have:
f(x)=1/(x-2)
g(x)
Then:
(fg)(x)=[1/(x-2)](g(x))=g(x)/(x-2)
Now; we calculate: (fg)`(x)
Remember: (u/v)=(u`v-vu´)/v²
Therefore:

(fg)´(x)=[g´(x)*(x-2) - 1*g(x)]/ (x-2)²
We know that:
g´(1)=-1
(fg)´(1)=6
Therefore:
6=[-1*(1-2)-g(1)]/(1-2)²
6=[1-g(1)]/1
6=1-g(1)
-g(1)=6-1
g(1)=-5
