Answer:
(See explanation for further details)
Step-by-step explanation:
The expression is transformed into its standard form:



The function does not represent a circle, as radius is a positive number.
No because ab can be divided by a and b.
Answer:
y= 13/2x +12
Step-by-step explanation:
so first move expression to right hand side
13x-2y+24=0
2y= 13x+24
then divide every term by 2 to cancel out 2
2y/2 = 13x/2 + 24/2
and then you get your final answer
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.
