Question

Даны векторы a{-2;3} и b{-4;-5}. Найдите a+2b.

Answer 1

(2;-3)×2+(-4;-5)=(0;-11

Answer 2

To find the vector sum a + 2b, you simply add corresponding components of the vectors. Given vectors a = {-2, 3} and b = {-4, -5}, the result will be:

a + 2b = (-2) + 2(-4), (3) + 2(-5) = {-2 - 8, 3 - 10} = {-10, -7}

So, the vector a + 2b is {-10, -7}.
