Step-by-step explanation:
D
Answer:
This statement is true for any N vectorial space.
By definition u·v=|u|·|v|·cos(α), where α is the angle between u and v.
If -1≤cos(α)≤1, we can assume:
|u·v|=||u|·|v|·cos(α)|=|u|·|v|·|cos(α)|≤|u|·|v|
Answer:
all real numbers i think
Step-by-step explanation:
Answer:
3
Step-by-step explanation:
So this is like a pie chart or fractions
20 degreees is x% or x/whole parts
circle=360degrees
20/360=2/36=1/18
so the area represents 1/18 of the circle
684=1/18 of circle
multply both sdies by 18
12312=18/18 circle
the area of the circle=12312 yd^2
