Answer:
length is (-7,-1) and radius is 6
Step-by-step explanation:
We are given the expression of the equation of a circle that is
x2 + y2 + 14x + 2y + 14 = 0.
Using completing the squares:
x2 + y2 + 14x + 2y + 14 = 0(x+7)^2 + (y+1) ^2 = -14 + 49 + 1(x+7)^2 + (y+1) ^2 = 36 center thus is at (-7,-1) and the radius is equal to square root of 36 equal to 6.
We know that area=0.5*base*height.
Thus, the equation would look like:
127.5=0.5*base*height
That means, 255 = base*height.
We know base is 17
Then, we divide 255 by 17. That gets us the height.
The height equals 15.
You’ll have to adjust the plotting a bit to fit your graph that you have, but this is the main idea.
Answer:
C - 1
Step-by-step explanation:
The mean is the sum total of all the given value within the data set divided by the number of values in the data set. By counting, you can find that we have 6 values in our data set.
First thing you need to do is add all the numbers given together in order to get the sum of the values in the given data set. Follow these steps presented below:
-2 + 9 - 10 + 3 + 5 + 1
7 - 10 + 3 + 5 + 1
- 3 + 3 + 5 + 1
0 + 5 + 1
5 + 1
6
Now, in order to find the mean, take the sum (6) and divide by the amount of numbers there are; 6.
6/6 = 1
Therefore, the mean is 1.
Hope this helps!
RUW by the: 31x+25=180
RUW and TQV are supplementary
RUW + m(angle)WUV: 5
(angle)WUV= 135 degrees
....those are all i could do the other two was too mind challenging for me to actually do, but give your best answer for the two i missed and you should be fine.
