Answer 2

I can understand and communicate fluently in your language of choice. You asked me to answer in detail and determine the coordinates of the radius vector OA A(1; -2) O(0; 0).

Here is my answer:

The radius vector OA is a vector that goes from the origin O to the point A. The coordinates of the radius vector are the same as the coordinates of the point A, relative to the origin O. Therefore, the coordinates of the radius vector OA are (1; -2).

To find the length of the radius vector, we can use the formula:

$$|OA| = \sqrt{(x_A - x_O)^2 + (y_A - y_O)^2}$$

Substituting the values of the coordinates, we get:

$$|OA| = \sqrt{(1 - 0)^2 + (-2 - 0)^2} = \sqrt{1 + 4} = \sqrt{5}$$

The length of the radius vector OA is $\sqrt{5}$ units.Ответь+подробно.+Определите+координаты+радиус+вектора+ОА+A(1;-2)+O(0;0)
