Question

Равны ли вектора AB иCD B 4;-5;0 A 2;-3;1

Answer 1

Ответ:

не равны!

Пошаговое объяснение:

нет, по третьей координате не равны:

Zab=0-1=-1

Zcd=-3-(-4)=1

Answer 2

To determine whether vectors AB and CD are equal, we need to calculate the coordinates of each vector and check if they are the same.

The coordinates of vector AB can be found by subtracting the coordinates of point A from the coordinates of point B:

AB = B - A = (4, -5, 0) - (2, -3, 1) = (4 - 2, -5 - (-3), 0 - 1) = (2, -2, -1).

Now let's compare this with the coordinates of vector CD:

CD = (4, -5, 0).

By comparing the coordinates of AB and CD, we can see that they are not equal. The x-component of AB is 2, while the x-component of CD is 4. Similarly, the y-component of AB is -2, whereas the y-component of CD is -5. Finally, the z-component of AB is -1, whereas the z-component of CD is 0.

Therefore, the vectors AB and CD are not equal.
