Answer: 10 units.
Step-by-step explanation:
The equation of the circle in Center-radius form is:

Where the center is (h,k) and "r" is the radius.
The equation of the circle given is:

You can observe that is written in Center-radius form.
Then, you can identify that:

Knowing this, you need to solve for "r" to find the lenght of the radius.
This is:

Therefore, the lenght of the radius is 10 units.
Answer:
The average rate of change of the cost of a pack is 22 cents per year.
Another name for the average <em>rate of change</em> is <em>slope</em>.
Step-by-step explanation:
The average rate of change of the cost of a pack (
), in monetary units per year, is equal to the change in the average cost of a pack (
), in monetary units, divided by the change in time (
), in years. Then, the average rate of change is:


The average rate of change of the cost of a pack is 22 cents per year.
Another name for the average <em>rate of change</em> is <em>slope</em>.
2x^3(x+1)-x(x+1)
(2x^3-x)(x+1)
x(2x^2-1)(x+1)
Answer:
c
Step-by-step explanation:
Answer:
(9/2, 9/2)
Step-by-step explanation:
midpoint formula = (x1 + x2/2, y1 + y2/2)
(7,6) is x1 and y1.
(2,3) is x2 and y2.
Solve:
x-coordinate= (7+2)/2 = 9/2 or 4.5
y-coordinate= (6+3)/2 = 9/2 or 4.5
your final answer is (9/2, 9/2)
decimal form = (4.5, 4.5)
