Answer:
Step-by-step explanation:
Since all of the edges of a cube are of equal length, there is no need to differentiate between the length, width and height. The volume of a cube is determined by multiplying the length of three edges of the cube. Let "a" define the length of an edge of the cube. This formula is also written as V = a³.
Hey there!
There are 94 dogs. This is more than any other pet. B is not right because the families that do have pets may have only 1. “Most” means more than half. 121 is less than half, so C isn’t correct. D is not correct because they could have more than one pet but we don’t know. So the answer is A.
I hope this helps!
Answer:
A. ![(x-4)^2+(y-3)^2=25](https://tex.z-dn.net/?f=%28x-4%29%5E2%2B%28y-3%29%5E2%3D25)
Step-by-step explanation:
Radius:
The length of diameter
is the distance between A and B.
![d=\sqrt{(8-0)^2+(6-0)^2}=\sqrt{64+36}=\sqrt{100}=10\\\\radius(r)=\frac{d}{2}=\frac{10}{2}=5](https://tex.z-dn.net/?f=d%3D%5Csqrt%7B%288-0%29%5E2%2B%286-0%29%5E2%7D%3D%5Csqrt%7B64%2B36%7D%3D%5Csqrt%7B100%7D%3D10%5C%5C%5C%5Cradius%28r%29%3D%5Cfrac%7Bd%7D%7B2%7D%3D%5Cfrac%7B10%7D%7B2%7D%3D5)
Centre:
Since A and B are end points of the diameter, centre is the mid point of these two. Let
be the centre of the circle.
![x=\frac{8+0}{2}=4\\\\y=\frac{6+0}{2}=3\\\\](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B8%2B0%7D%7B2%7D%3D4%5C%5C%5C%5Cy%3D%5Cfrac%7B6%2B0%7D%7B2%7D%3D3%5C%5C%5C%5C)
Centre is ![(4,3)](https://tex.z-dn.net/?f=%284%2C3%29)
Equation of circle:
If
is the centre of the circle and
be the radius. Equation of circle is given by:
![(x-a)^2+(y-b)^2=r^2](https://tex.z-dn.net/?f=%28x-a%29%5E2%2B%28y-b%29%5E2%3Dr%5E2)
![Here\ (a,b)=(4,3)\ and\ r=5\\Equation:\ (x-4)^2+(y-3)^2=5^2\\(x-4)^2+(y-3)^2=25](https://tex.z-dn.net/?f=Here%5C%20%28a%2Cb%29%3D%284%2C3%29%5C%20and%5C%20r%3D5%5C%5CEquation%3A%5C%20%28x-4%29%5E2%2B%28y-3%29%5E2%3D5%5E2%5C%5C%28x-4%29%5E2%2B%28y-3%29%5E2%3D25)
