Define the unit vectors along the x and y axes as

correspondingly.
Consequently, the vector from P to Q is

In terms of components, vector PQ is represented as (-8,5).
The magnitude of vector PQ can be calculated as
√[(-8)² + 5²] = √(89) = 9.434
Answer:
Thus, vector PQ is (-8, 5), and its magnitude equals √89 (or 9.434).
Answer:
We require a total of 144 birthday candles for the 12 parties.
Step-by-step explanation:
As a caterer focused on children’s birthday celebrations, you have 12 events to cater to in the upcoming week, each requiring 2 cakes. Each cake will be adorned with 6 candles.
