The average cost of a computer in the year 2008 is given as:
Now, the difference in average cost between the years 2008 and 2000 can be calculated by subtracting the average cost in 2000 from the average cost in 2008.
Framing in equation form, we get:
Difference in average cost (ΔC) is given as:
Therefore, the difference in the costs for a computer between 2008 and 2000 is

Answer:
Center: (3, -2)
Radius: 4.
Step-by-step explanation:
The equation of a circle is (x - h)^2 + (y - k)^2 = r^2.
In this case, the equation given is (x - 3)^2 + (y + 2)^2 = 16.
That means that h = 3, and k = -2. In other words, the center of the circle is (3, -2).
The radius will be
= 4
