Answer:
At x = 2 and 10.
Step-by-step explanation:
Given : The cost of producing x hundred items is given by the equation 
The revenue generated from sales of x hundred units is given by the equation 
To Find :What values of x will the company break even?
Solution:
Cost function :
Revenue function :
Now to find the company break even :
So, x = 2,10
Hence the company break even at x = 2 and 10.
It is right it is C 454.5
Step One
Develop a formula for the perimeter.
Argument
What you see is a semicircle going upwards and another one going downwards. Two semicircles =1 circle.
The "perimeter" [Circumfrence] of a whole circle = 2*pi*r
We are told that whatever you call this the perimeter is 8pi + 16
Step Two
Set up the equation
8pi + 16 = 2*pi*r + 4r Including the line connecting these two.
Step Three
Take out the common factors on the left and right.
8(pi + 2) = 2r(pi + 2) Divide both sides by pi + 2
8 = 2r Divide by 2
4 = r
Sorry. I didn't know the meaning of perimeter. Mathmate is perfectly correct.
Answer:
-5<x<10
Step-by-step explanation:
1) -6< x-1<9
you take -1 out for both sides and it changes the sign
-6 +1< x< 9+1
-5<x<10
Good luck!
