Question

Find an ordered pair that represents the vector from A(31,-33) to B(36,-45). Then find the magnitude of AB.​

Answer 1

Answer:

• AB = (5, -12)
• |AB| = 13

Step-by-step explanation:

AB = B - A = (36, -45) - (31,-33) = (36 -31, -45-(-33))

AB = (5, -12)

__

The magnitude of a vector is the root of the sum of the squares of its components.

  |AB| = √(5² +(-12)²) = √(25 +144) = √169

  |AB| = 13
