The x-coordinate of a point is -1. Which of the following points could it be? A. (-1,2) B. (2,-1) C. (1,-2) D. (-2,1) 相关知识点: 试题来源: 解析 A。x 坐标是-1 的点是(-1,某个数)的形式。B 选项 x 坐标是 2;C 选项 x 坐标是 1;D 选项 x 坐标是-2。
The coordinate of a point is (-5, 0), then it lies on: A. x-axis B. y-axis C. Quadran
(align*)(x &=r cos θ x &=5 cos 221° x &=5(-0.7547) x &=-3.77)(align*) The (align*)x(align*) -coordinate of a point on a circle of radius 5 units, which makes an angle of (align*)221°(align*) is -3.77.The answer is TRUE.反馈...
We consider how a linear condition on the bits representing an x-coordinate of a point on an elliptic curve over a field of characteristic two can lead to problems both in elliptic curve based Diffie–Hellman key agreement and the method of distinguished points for solving the elliptic curve ...
If the coordinate of a point is (x, y) and it is reflected across the x-axis, the new coordinate is ___. A. (-x, y) B. (x, -y) C. (-x, -y) D. (y, x) 相关知识点: 试题来源: 解析 B。点(x, y)关于 x 轴反射,纵坐标变为相反数,即新坐标为(x, -y)。反馈...
A. x-axis B. y-axis C. origin D. quadrant 相关知识点: 试题来源: 解析 B。本题考查纵坐标的含义。纵坐标表示点在 y 轴上的位置。选项 A x 轴对应的是横坐标;选项 C 原点不是纵坐标表示的位置;选项 D 象限不是纵坐标单独决定的。反馈 收藏 ...
Points in a coordinate system can be determined by their x-coordinate and y-coordinate. 2. 这个点的x坐标是5。 The x-coordinate of this point is 5. 3. 我们可以通过改变x坐标的值来移动这个点。 We can move this point by changing the value of its x-coordinate. 4. 在二维图形中,x轴通常...
