The linear cost function is
Step-by-step explanation:
A linear cost function expresses cost as linear function of the number of items
Here, C(x) is the total cost, and x is the number of items. The slope m is called the marginal cost and b is called the fixed cost.
From the information given we know
m = $40 and C(180) = $9500
We can find the value of b in this way
solving for b
The linear cost function is

Step-by-step explanation:
We have been given equation of a circle in general form
. We are asked to find the equation of the circle in standard form.
We know that equation of a circle in standard form is of format:
, where (h,k) represents the center of the circle and r represents radius.
We will convert our given equation in standard form by completing the squares as shown below:
Adding
to both sides of our equation we will get,
Therefore, the equation of the given circle in standard form would be
.
