Answer:
![(x+7)^{2}+ (y-2)^{2}=49](https://tex.z-dn.net/?f=%28x%2B7%29%5E%7B2%7D%2B%20%28y-2%29%5E%7B2%7D%3D49)
Step-by-step explanation:
It is given that circle is a tangent to y axis, which tells us that the distance between the centre point and y axis is the radius of the triangle.
Formula for equation of circle with centre (x1,y1) and radius r is
![(x-x1)^{2}+ (y-y1)^{2}=r^{2}](https://tex.z-dn.net/?f=%28x-x1%29%5E%7B2%7D%2B%20%28y-y1%29%5E%7B2%7D%3Dr%5E%7B2%7D)
In the given case distance between the centre and y axis is 7 units so radius would be 7 and the centre point is (-7,2),
the equation of circle is ,
![(x+7)^{2}+ (y-2)^{2}=7^{2}](https://tex.z-dn.net/?f=%28x%2B7%29%5E%7B2%7D%2B%20%28y-2%29%5E%7B2%7D%3D7%5E%7B2%7D)
![(x+7)^{2}+ (y-2)^{2}=49](https://tex.z-dn.net/?f=%28x%2B7%29%5E%7B2%7D%2B%20%28y-2%29%5E%7B2%7D%3D49)
Hence the abow equation is the circle equation.
Answer:
Option (8).Plane BPQ
Option (9).Plane OPB
Step-by-step explanation:
Any plane is described by three different points lying on the the same surface.
And planes having common edge will have the common points of the given edge.
Therefore, planes given in the picture which will have the common side BP are,
Plane BPQ and plane OPB.
Therefore, Option (8) and Option (9) are the answer.

Answer:
(47xy)/(6√3)
Step-by-step explanation:
A variable term is one that contains one or more variables, possibly with a coefficient. We can use 47xy as our variable term.
A constant is some number, or a representative of a particular number. π and e and Ф are representative of irrational constants. Of course, any number is also a constant. We can use 6√3 as our constant.
A quotient is formed when a first value is divided by a second value.
Here is the quotient of our variable term and our constant:
![\dfrac{47xy}{6\sqrt{3}}](https://tex.z-dn.net/?f=%5Cdfrac%7B47xy%7D%7B6%5Csqrt%7B3%7D%7D)
