Answer:
![(x+8)^2 +(y-4)^2 = 25](https://tex.z-dn.net/?f=%20%28x%2B8%29%5E2%20%2B%28y-4%29%5E2%20%3D%2025)
Step-by-step explanation:
Assuming this complete problem: "A cell tower is located at (-8, 4) and transmits a circular signal that covers three major cities. The three cities are located on the circle and have the following coordinates: G (-4, 7), H (-13, 4), and I (-8, -1). Find the equation of the circle"
For this case the generla equation for the circle is given by:
![(x-h)^2 +(y-k)^2 = r^2](https://tex.z-dn.net/?f=%20%28x-h%29%5E2%20%2B%28y-k%29%5E2%20%3D%20r%5E2)
From the info we know that the tower is located at (-8, 4) so then h = -8 and k = 4, so then we need to find the radius. So we have the equation like this:![(x+8)^2 +(y-4)^2 = r^2](https://tex.z-dn.net/?f=%20%28x%2B8%29%5E2%20%2B%28y-4%29%5E2%20%3D%20r%5E2)
If the 3 points are on the circle then satisfy the equation. We can use the first point (-4,7) and if we replace we can find the value for ![r^2](https://tex.z-dn.net/?f=r%5E2)
![(-4+8)^2 +(7-4)^2 =25= r^2](https://tex.z-dn.net/?f=%20%28-4%2B8%29%5E2%20%2B%287-4%29%5E2%20%3D25%3D%20r%5E2)
So then ![r = \sqrt{25}=5](https://tex.z-dn.net/?f=%20r%20%3D%20%5Csqrt%7B25%7D%3D5)
And if we replace the second point we got this:
![(-13+8)^2 +(4-4)^2 = 25 =r^2](https://tex.z-dn.net/?f=%20%28-13%2B8%29%5E2%20%2B%284-4%29%5E2%20%3D%2025%20%3Dr%5E2)
And for the third point we have:
![(-8+8)^2 +(-1-4)^2 = 25 =r^2](https://tex.z-dn.net/?f=%20%28-8%2B8%29%5E2%20%2B%28-1-4%29%5E2%20%3D%2025%20%3Dr%5E2)
And we got the same result.
So then our final equation is given:
![(x+8)^2 +(y-4)^2 = 25](https://tex.z-dn.net/?f=%20%28x%2B8%29%5E2%20%2B%28y-4%29%5E2%20%3D%2025)

Answer:
246 calories in 21 oz
Step-by-step explanation:
Set up a proportion.
70 oz / 820 calories = 21 oz / x Cross muliply
70x = 820*21 Combine the right.
70x = 17220 Divide by 70
70x/70 = 17220/70
x = 246 Calories
