What is multiplication?
Multiplication is the process of multiplying, therefore, adding a number to itself for the number of times stated. For example, 3 × 4 means 3 is added to itself 4 times, and vice versa for the other number.
The product of two vectors is written as,
[tex]r \cdot s = |r|\cdot |s| \times \cos(\hat I)[/tex]
Substituting the values,
125 = 16 · 9 × Cos(θ)
0.868 = Cos(θ)
θ = 29.766°
Hence, the angle θ between vectors r and s is 29.766°.
