Answer:The points on the circle which have an x-coordinate of 1 are:. (1,+√15) and (1,-√15)
Explanation:
The points on the circle which have an x-coordinate of 1 are:. (1,+√15) and (1,-√15)
The equation of a circle usually takes the form;
(x-a)² + (y-b)² = r²
where a and b are x- and y- coordinates of the center of the circle.
In this scenario, the center is at the origin (0,0).
In essence, the points on the circle which have an x-coordinate of 1 can be evaluated as follows;
(1-0)² + (y - 0)² = 4²
1 + y² = 16.
y² = 15
y = ±√15.
The points on the circle which have an x-coordinate of 1 are:. (1,+√15) and (1,-√15)
