Question

Write ef as the sum of unit vectors e(-12, 15, -9) and f(-12, 17, -22).

Answer 1

C. 2j-13k

just took the test

Answer 2

C. 2j-13k

Explanation:

EF is another way of saying F - E. To solve this problem, simply subtract the values of E from F.

-12 - (-12) = 0

17 - 15 = 2

-22 - (-9) = -13

The equation you will end up with will look like 2j-13k.
