Alice is playing a single-player game on the number axis.There are n points on the number axis. Each time, the player selects two points. The two points will be removed, and their midpoint will be added. When there is only one point on the axis, the game ends. Formally, if the ...
A and B corresponding to numbers 7 and b respectively, and the distance between A and B is less than 10.Let m=5−2b, then the range of the value of m is( ). (英汉词典:number axis 数轴;point 点;corresponding to 对应于…;respectively 分别地;distance 距离;less than 小于;value 值,...
每一个实数都能用有理数去逼近到任意精确的程度,这就是有理数的稠密性。The rational points are dense on the number axis.

A. (2, 0) B. (0, 2) C. (-2, -2) D. (2, 2) 相关知识点: 试题来源: 解析 A。解析:在平面直角坐标系中,点在 x 轴上时,其纵坐标为 0。点(2, 0)的纵坐标为 0,所以在 x 轴上。选项 B 点(0, 2)在 y 轴上;选项 C 点(-2, -2)不在坐标轴上;选项 D 点(2, 2)不在坐...
In the figure above, P and S are points on the x-axis. What is the area of square PQRS ?() (1)The coordinates of point P are (2, 0) (2)The coordinates of point R are (6, 4) A.条件(1)充分,但条件(2)不充分. B.条件(2)充分,但条件(1)不充分. C.条件(1)和(2)单独都...
题目Which of the following points lies on the x-axis? A. (0, 5) B. (5, 0) C. (0, -5) D. (-5, 0) 相关知识点: 试题来源: 解析 B。在平面直角坐标系中,位于 x 轴上的点纵坐标为 0。选项 B 中坐标为(5, 0),纵坐标为 0,所以该点在 x 轴上。
A) 0 B) 1 C) -1 D) Any number Solution The answer is A. The ordinate of all points on the x-axis is zero because ordinate ( or y-coordinate) of a point is the perpendicular distance of this point from the x-axis measured along the y-axis. If the ...
