Answer:
|2a + b| = 2√(3) + 1
Step-by-step explanation:
|a| = √(3)
|b| = 1
θ = 5π/6
For scalar vectors, A.B = |a|.|b|.cosθ
a
|2a| = 2*√(3) = 2√(3)
|2a + b| = 2√(3) + 1
Since we don't have to find the scalar or dot product, there's no need to use the formula requiring the angle between them
|2a + b| = 2√(3) + 1
Answer:
23.40
Step-by-step explanation:
150/100=1.5
9.36*1.5=14.04
9.36+14.04=23.40 per dozen of roses
