1 столбец

KM(-2;2)  (Объяснение: KM (3-5;0-(-2)))

2KM(-4;4) (Домножаем на 2 координаты вектора KM)

-0.5KM(1;-1) (Домножаем на -1/2 координаты вектора KM)

|KM|= √((-2)²+2²) = √8=2√2

2 столбец

M (-2; 1)

2KM (16;0)

-0.5KM (-4;0)

|KM|=8

3 столбец

К (-3;0)

2KM (6,4)

-0.5KM (-3/2; -1)

|KM| = √13

Ychenik20006: огромное ср
