Question

Suppose vector c = vector a + vector b where vector vector a has components vector a x = 4, vector a y = 2 and vector vector b has components vector b x = -2, vector b y = -5.

Answer 1

Given

(ax, ay) = (4, 2)

(bx, by) = (-2, -5)

c = a + b

Find

c

Solution

cx = ax + bx = 4 + (-2) = 2

cy = ay + by = 2 + (-5) = -3

Vector c is (2, -3).
