The standard form of the equation of a circle is
.
Solution:
Center of the circle = (6, 4)
Radius of the circle = ![\sqrt{7}](https://tex.z-dn.net/?f=%5Csqrt%7B7%7D)
<u>To find the equation of the circle:</u>
General formula for the equation of a circle
![(x-h)^{2}+(y-k)^{2}=r^{2}](https://tex.z-dn.net/?f=%28x-h%29%5E%7B2%7D%2B%28y-k%29%5E%7B2%7D%3Dr%5E%7B2%7D)
where (h, k) is the center of the circle and r is the radius of the circle.
Here, h = 6, k = 4 and r = ![\sqrt{7}](https://tex.z-dn.net/?f=%5Csqrt%7B7%7D)
![(x-6)^{2}+(y-4)^{2}=(\sqrt{7}) ^{2}](https://tex.z-dn.net/?f=%28x-6%29%5E%7B2%7D%2B%28y-4%29%5E%7B2%7D%3D%28%5Csqrt%7B7%7D%29%20%5E%7B2%7D)
![(x-6)^{2}+(y-4)^{2}=7](https://tex.z-dn.net/?f=%28x-6%29%5E%7B2%7D%2B%28y-4%29%5E%7B2%7D%3D7)
Hence the standard form of the equation of a circle is
.
Answer: that is equivalent to 447
Step-by-step explanation:
Answer:
Proof:
By the inscribed angle theorem, we know that angle BAC is equal to angle DEC. By the second corollary to the inscribed angle theorem, we know that line segment AE is perpendicular to line segment AC. Therefore, line segment AE is tangent to circle C.
Step-by-step explanation:
Analyze and ensure the answer is correct.
Here is how to solve it.
65% of 160
65/100(160)
=(65/100)(160/1)
=(13/20)(160/1)
=(13)(160)/(20)(1)
=2080/20
=104
Therefore they won 104 games! :D
Answer:
21z+84
Step-by-step explanation.
7x3=21 then put the z at the end 21z.
7x12=84. Put it after the 21z. 21z+84
