Answer:
x = 129
y = 82
Step-by-step explanation:
x + 51 = 180
x = 180 - 51
x = 129
y + 51 + 47 = 180
y = 98 - 180
y = 82
Answer:
The correct answer is 10 for lowest average cost and the cost function is 0.2
+ 75x + 20.
Step-by-step explanation:
Average cost function is given by = 
= C(x) = 0.2x + 
+75.
For minimizing we need to find 
C(x) = 0.
⇒ C(x) = 0.2 - 
.
⇒ = 0.2
⇒ = 100.
⇒ x = ±10
⇒ x = 10 ; cost cannot be negative.
Second order derivative is positive which implies the average cost minimizes.
Original cost function is given by C(x) × x = 0.2 + 75x + 20.
First, let's try to isolate x to make the question easier to solve.
|2x-6|≤6
2x - 6 ≤ 6
2x - 6 ≥ -6
2x ≤ 12
x ≤ 6
2x ≥ 0
x ≥ 0
Knowing this, the graph should be equal or less than 6 and equal or greater than 0, making Option D the correct answer.
