Question

Tolong dijawab dong, besok dikumpul soalnya.

Answer 1

1. r = [4.(1)^2 + 2.(1)]i + [8.(1)]j = 6i + 8j =akar 6^2 + 8^2 = akar 100 = 10

2. 3.2i + 4.2j = 6i + 8j = (6;8)

3. Ro=[2.(0)^2+ 4.(0) + 2]i + [3.(0)^2 + 2]j = 2i + 2j
R1=[2.(1)^2+ 4.(1) + 2]i + [3.(1)^2 + 2]j = 8i + 5j
perpindahab (8-2)i + (5-2)j = 6i + 3j
