Answer:
Center: (0,0)
Radius: 3
The graph is attached.
Step-by-step explanation:
The equation of the circle has the form:
![(x -h)^{2}+(y-k)^{2}=r^{2}](https://tex.z-dn.net/?f=%28x%20-h%29%5E%7B2%7D%2B%28y-k%29%5E%7B2%7D%3Dr%5E%7B2%7D)
Where (h,k) is the point of the center of the circle and r is the radius of the circle.
If the center is at (0,0) and the radius is 3, you obtain the equation given in the problem:
![(x -0)^{2}+(y-0)^{2}=3^{2}](https://tex.z-dn.net/?f=%28x%20-0%29%5E%7B2%7D%2B%28y-0%29%5E%7B2%7D%3D3%5E%7B2%7D)
![x^{2}+y^{2}=9](https://tex.z-dn.net/?f=x%5E%7B2%7D%2By%5E%7B2%7D%3D9)
Therefore, the center is (0,0) and radius is 3.
You can graph the circle with its center at the origin and a radius of 3 as you can see in the figure attached.
c+2 increases linearly with c. That means that if c increases by 1, c+2 will increase by 1; if by 2, c+2 will increase by 2; and so on.
y = c+2 is a "linear function of c."
Answer:
let the unknown number be = n, and the difference between the number be = X
7,X,n
X = 32/4
ans =8. 8 is the difference between 7 and n
where by n = 16
Answer:
C. 19/18
Step-by-step explanation:
![\frac{1}{9} + \frac{2}{3} + \frac{5}{18 } = \frac{2}{18} + \frac{12}{18} + \frac{5}{18} = \frac{19}{18}](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7B9%7D%20%20%2B%20%20%5Cfrac%7B2%7D%7B3%7D%20%20%2B%20%20%5Cfrac%7B5%7D%7B18%20%7D%20%20%3D%20%20%5Cfrac%7B2%7D%7B18%7D%20%20%2B%20%20%5Cfrac%7B12%7D%7B18%7D%20%20%2B%20%20%5Cfrac%7B5%7D%7B18%7D%20%20%3D%20%20%5Cfrac%7B19%7D%7B18%7D%20)
So the answer is C. 19/18
