Question

Надйите координаты a-2b, если a{-3;6;s} и b{0;1;-2}​

Answer 1

Ответ:

Сложение и умножение векторов.

Answer 2

To find the coordinates of a - 2b, we need to subtract twice the vector b from the vector a. Vector subtraction is done by subtracting corresponding components of the vectors.

Given vectors: a = {-3, 6, s} b = {0, 1, -2}

To find a - 2b, we perform the following calculations: a - 2b = {-3 - 2(0), 6 - 2(1), s - 2(-2)} = {-3, 6 - 2, s + 4} = {-3, 4, s + 4}

So, the coordinates of a - 2b are {-3, 4, s + 4}.
