In summary, you just multiply the percentage (move the decimal twice to the left) by the amount, which is 70 in this case.
0.47 x 70 = 32.9
The correct answer is 28.3.
You take 22/1.4 and get 15.7142857143. Then you take 15.7142857143*1.8 which equals 28.2857142857 so you round it up to 28.3 which is the answer.
I hope this helps you:)
The given points are
P = (-4,11)
Q = (-5,8)
The x-component of vector QP is
-4 - (-5) = 1
The y-component of vector QP is
11 - 8 = 3
The vector QP is
(1,3) or

The magnitude of the vector is
√(1² + 3²) = √(10)
Answer:

The magnitude is √(10).
