A: The center is the mid point of the diameter. So, the center of the circle will be the midpoint of points P and Q. The coordinates of the midpoint are the averaged coordinates of the endpoints.
So, the x-cooardinate of the center is the average of the x-coordinates of P and Q:
Try to do the same thing with the y coordinates, and you'll get the y-coordinate . This first part will be over, because the circle will be point
B: The radius is exactly half the diameter. So, we find the length of the diameter, and we divide it by 2. To find the length of the diameter, we use the standard formula for the distance between two points:
Divide this length by 2 and you'll get the radius.
C: At this point, we have both the radius and the coordinates of the center. The equation of the circle depends on these two parameters, and it is
Substitute and with the coordinates of the center (found in point A.) and with the radius (found in point B.) and you'll have the equation of the circle.
Answer:3/7
Step-by-step explanation:
3 * 1/7 is
3 * 1 = 3
Divided by 7 = 3/7
There’s nothing to simply, as that fraction cannot be reduced
Answer:
-6 - (-8) = 2.
Your number line might have a bubble at 2. Or it may show movement 8 units to the right of -6. Whatever it is, you should end up at the value of 2.
Step-by-step explanation:
If There is a math equation you can use math-way.
Also it would help if you can take a better picture.
Once you take a better picture I promise i will try my best to answer the question.
The correlation coefficient r of the data set is <em>-0.28</em>
