Answer: c
Step-by-step explanation:
For this case we have that by definition, the general equation of the circle is given by:
![(x-h) ^ 2 + (y-k) ^ 2 = r ^ 2](https://tex.z-dn.net/?f=%28x-h%29%20%5E%202%20%2B%20%28y-k%29%20%5E%202%20%3D%20r%20%5E%202)
Where,
- <em>(h, k): it is the center of the circle
</em>
- <em>r: radius of the circle
</em>
We then have the following equation:
![(x-11) ^ 2 + (y + 15) ^ 2 = 144](https://tex.z-dn.net/?f=%28x-11%29%20%5E%202%20%2B%20%28y%20%2B%2015%29%20%5E%202%20%3D%20144)
Comparing values we have:
For the center of the circle
:
![(h, k) :( 11, -15)](https://tex.z-dn.net/?f=%28h%2C%20k%29%20%3A%28%2011%2C%20-15%29)
For the radius:
![r ^ 2 = 144\\r = \sqrt {144}\\r = 12](https://tex.z-dn.net/?f=r%20%5E%202%20%3D%20144%5C%5Cr%20%3D%20%5Csqrt%20%7B144%7D%5C%5Cr%20%3D%2012)
Then, the diameter is given by:
![d = 2r\\d = 2 (12)\\d = 24](https://tex.z-dn.net/?f=d%20%3D%202r%5C%5Cd%20%3D%202%20%2812%29%5C%5Cd%20%3D%2024)
Answer:
Johnny is wrong:
The center of the circle is (11, -15)
Joyce is wrong:
The diameter of the circle is 24

Answer:
Option (4)
Step-by-step explanation:
From the picture attached,
Side lengths of the triangles have been given in the picture attached.
If these triangles are similar, their corresponding sides will be proportional.
By this property of similarity,
![\frac{19.5}{5}= \frac{20}{8}](https://tex.z-dn.net/?f=%5Cfrac%7B19.5%7D%7B5%7D%3D%20%5Cfrac%7B20%7D%7B8%7D)
3.9 = 2.5
Which is not true.
Therefore, these triangles are not similar.
Option (4) will be the answer.
