Given that P(5, 11) and Q(6, 4) find the component form and magnitude of QP

To find the component form of the vector QP, we first need to determine the coordinates of the vector. The vector QP is obtained by subtracting the coordinates of point P from those of point Q.

The coordinates of point Q are (6, 4) and the coordinates of point P are (5, 11).

So, the component form of the vector QP is:

  • QP = Q – P
  • QP = (6 – 5, 4 – 11)
  • QP = (1, -7)

This means the vector QP can be represented as (1, -7).

Next, we need to find the magnitude of the vector QP. The magnitude of a vector (a, b) can be found using the formula:

|QP| = √(a² + b²)

For our vector QP = (1, -7):

  • |QP| = √(1² + (-7)²)
  • |QP| = √(1 + 49)
  • |QP| = √50
  • |QP| = 5√2

Thus, the magnitude of vector QP is 5√2.
