Given:
The equation of a circle is:

To find:
The center and radius of the circle.
Solution:
We have,

To make complete square add square of half of x and square of half of y on both sides.




...(i)
The standard form of a circle is:
...(ii)
On comparing both sides, we get

Therefore, the center of the circle is (-2,3) and the radius is 3 units.
Answer:
If circumference = 25, then 90 degrees (one quarter of a circle) = 25 / 4 = 6.25 meters.

Given: The distance from the centroid of a triangle to its vertices are
,
, and
.
To Find: Length of shortest median.
Solution:
Consider the figure attached
A centroid is an intersection point of medians of a triangle.
Also,
A centroid divides a median in a ratio of 2:1.
Let G be the centroid, and vertices are A,B and C.
length of

length of

length of

as centrod divides median in ratio of 
length of



length of



length of



Hence the shortest median is
of length

Step-by-step explanation:
Answer:
- g(x) = root(3, x-1)
- h(x) = root(3, x) -1
Step-by-step explanation:
The graph of f(x) is translated (right, up) = (h, k) to ...
g(x) = f(x -h) +k
___
Graph B is translated right 1 unit, so its function is ...
g(x) = f(x -1) = root(3, x-1)
__
Graph C is translated down 1 unit, so its function is ...
h(x) = f(x) -1 = root(3, x) -1
