In the rectangular coordinate system, (x, y) is a point on a circle that has center (3, 2) and is tangent to the x-axis at (3, 0).
Quantity A: The least possible value of x
Quantity B: 0
选项
A、Quantity A is greater.
B、Quantity B is greater.
C、The two quantities are equal.
D、The relationship cannot be determined from the information given.
答案
A
解析
圆心(3,2),x轴与圆相切于(3,0),说明半径为2。所以圆周最左侧的点是(1,2),所以X最小值是1,大于0,故答案为A。
