If the midpoint of the line segment joining points A(x₁, y₁) and B(x₂, y₂) is (3, 4) and A is (1, 2), what is the coordinate of B? A. (5, 6) B. (5, 2) C. (2, 6) D. (2, 2) 相关知识点: 试题来源: 解析 A。此题创新在
相关知识点: 试题来源: 解析 A。中点坐标公式为 ( (x1 + x2) / 2, (y1 + y2) / 2 ) ,已知中点为 (3, 4) ,(x1, y1) = (1, 2) ,则 x2 = 2×3 - 1 = 5,y2 = 2×4 - 2 = 6,所以 (x2, y2) 为 (5, 6) 。反馈 收藏 ...
Flow DS now serves as the cornerstone for the creation of digital interfaces in the post-Covid era: it functions as a virtual playground, facilitating a global community of designers and developers to access component libraries and guidelines on a daily basis. 斯柯达是汽车制造商中的先驱者,率先采...
Yes. Network Control Protocol (NCP) in Point-to-Point Protocol (PPP) can be used to obtain the IP address of the peer device. Therefore, even if the IP addresses of both ends of the link are not on the same network segment, the two devices can ping each other....

If Q(2, 4) is the mid-point of the line segment joining the points P(a, b) and R(-1, -3) then find the co-ordinates of point P. 相关知识点: 试题来源: 解析 LetP(a,b)=(x_1,y_1) and the origin (-1,-3)=(x,y_2 and Q(2, 4) be the mid-point of PR then by...
Suppose we have two points, P(x_0,y_0) an d Q(x_1,y_1) , in the plane. By the distance d between P an d Q, we mean the length of the line segment joining P with Q. (Remember, given any two distinct points in the plane, there is a unique line containing both points.)...

5b). That is, AcrIF24 induces strong non-specific DNA binding activity in the Csy complex, which is dependent on both AcrIF24 and Csy, and their interactions. To further investigate this activity of AcrIF24, we purified Csy with AcrIF24 as a complex by co-expression. Titration ...
