The answer is Strong Positive
Answer:
$9327
Step-by-step explanation:
Apparently, the cost function is supposed to be ...
C(x) = 0.4x^2 -112x +17167
This can be rewritten to vertex form as ...
C(x) = 0.4(x^2 -280) +17167
C(x) = 0.4(x -140)^2 +17167 -0.4(19600)
C(x) = 0.4(x -140)^2 +9327
The vertex of the cost function is ...
(x, C(x)) = (140, 9327)
The minimum unit cost is $9327.
_____
<em>Comment on the question</em>
You found the number of units that result in minimum cost (140 units), but you have to evaluate C(140) to find the minimum unit cost.
Divide both sides by their LCD, 2
2/4 = 1/2
1/2 is irreducible
Answer:
Option C is correct.
Step-by-step explanation:
Given Equation:

To find: Solution of the Equation.
Consider,





b² = 0 ⇒ b = 0
b - 4 = 0 ⇒ b = 4
Therefore, Option C is correct.
Answer: 26
2³ + 4(2 + x) for x = 10
- first do 4(2 + x) which is
8+4x
- Evaluate 2 cubed
You get 2 times 2 times 2.
That would get 8
Our expression is 8 + 8+x
x = 10
Substitute the values.
It is Now eight plus 8 plus ten
So when you Calculate eight plus 8 plus 10
You will get 26
