Given:
Center of a circle is at point C(-1,2).
AB is the diameter of the circle.
Coordinates of the point A are A(2,6).
To find:
The coordinates of point B.
Solution:
Let the coordinates of point B are (a,b).
If AB is the diameter of the circle, then A and B are end points of diameter of the circle and the center C is the midpoint of AB.
Point C = Midpoint of AB
On comparing both sides, we get
Similarly,
Therefore, the coordinates of point B are (-4,-2).
Answer:
it b
Step-by-step explanation:
Solve equation [1] for the variable x [1] x = 3y - 1
// Plug this in for variable x in equation [2] [2] 8y - 2•(3y-1) = 4
[2] 2y = 2
// Solve equation [2] for the variable y [2] 2y = 2
[2] y = 1
// By now we know this much : y = 1
x = 3y-1// Use the y value to solve for x x = 3(1)-1 = 2
5 and 4/5 =
5 * /5 (the five as a denominator) = 25.
The 25 is added to the numerator. 25 + 4 = 29. The answer over the denominator (it stays the same) is 29/4
How long is one lap? Multiply that by three and convert it into meters.
simplified is
I got this by dividing both the numerator and denominator by 4
Hope this helps
