Π/12 is half of π/6, which is 30 degree
tan(α/2)=(1-cosα)/sinα)
plug in the values: tan(π/12)=(1-cosπ/6)/sin(π/6)=(1-√3/2)/(1/2)=2-√3
Answer:
First table
Step-by-step explanation:
The first table shows the relationship y=1/7x
The second table doesn't show a relationship due to (6,15)
The third table doesn't show a relationship due to (3,5)
The fourth table doesn't show a relationship due to (2,10)
So the first table is correct
You substitute the x with 1
Y=-2x(1)+8
So y = 6
7 x 106 = 742 3.5 x 10 = 35 742-35=701.it is 701 time larger
