Several vectors in the x-y plane are shown in the figure with their tails at the origin of the coordinate system and with a label at their heads. Two of these vectors are given in terms of the unit-vectors I and j as

P = (3.20 i + 4.90 j) and

Q = (-4.10 i + 6.00 j),

Where I and j are measured in meters.

Let M = (P+Q). Calculate the magnitude of the vector M.
