Three identical coins, labeled A, B, and C in the figure, lie on three corners of a square 10.0 cm on a side. Determine the x co
ordinate of each coin, xA, xB, and xC. (See figure.)
2 answers:
The coordinates of the point A is
.
The coordinates of the point B is
.
The coordinates of the point C is
.
Further explanation:
Given:
The coin labeled as A lies on the -axis.
The coin labeled as B lies on the origin.
The coin labeled as C lies on the -axis.
The distance of the point B and C is .
Concept used:
The point which lies on the -axis, the value of its
-coordinate is
.
The point which lies on the -axis, their
-coordinate is
.
The coordinate of the origin is .
Calculation:
The coin labeled as A lies on the -axis therefore the
-coordinate of the point is
.
The coin labeled as B lies on the origin therefore the -coordinate of the point is
.
The distance from point B to the point C is and the coin labeled as C lies on the x axis it means that the
-coordinate of the point is
.
Therefore, the coordinate of the point A is
.
The coordinate of the point B is
.
The coordinate of the point C is
.

Your equation is
Step-by-step explanation:
Well, the center origin of the circle is given (h,k) = (1,-1).
We have to find our radius as they gave us a point. from origin to the edge of the circle.
Using the formula: (x - h)^2 + (y - k)^2 = r^2
Plug in our (h,k) = (1,-1) and (x,y) = (0.5,-1) to solve for radius.
(x - h)^2 + (y - k)^2 = r^2
(0.5 - (1))^2 + (-1 - (-1))^2 = r^2
(-0.5)^2 + (0)^2 = r^2
1/4= r^2
r^2 = 1/4
r = 1/2
