Vector PQ=(7-5, 3-4)=(2, -1).  4RS=4 \cdot (4-8, 1-6) = 4 \cdot (-4, -5) = (-16, -20).  So the sum is (-14, -21).

For the second, the magnitude is the square root of the sum of the squares of the components.  This is equal to \sqrt{(-14)^2+(-21)^2} = \sqrt{637}=7\sqrt{13}.

Pls help! evaluate f(4) on this table
Kruka [31]

Answer:
