Step-by-step explanation:
The coefficent of the x variable is b.
The formula for the period is

Here, b is 6 so we have

So the period is pi/3, or 60 degrees
Answer:
THE ANWSER IS 4
Step-by-step explanation:
Answer:
10%
Step-by-step explanation:
First, get the drop in value by deducting the price this year from last year's price.
Value decrease=$52.00-$46.80=$5.20
To express it as a percentage, we divide it by the original price which was $52.00 then multiply by 100 hence the percentage decrease will be

Therefore, the price decreases by 10%
The answer is
AB = 6.
External value x (external value + internal value) =
External value x (external value + internal value) of the other side
Substitute, transpose, and simplify.
TA x (TA + AB) = TC x (TC + CD)
10 x (10 + (x + 2)) = 8 x (8 + 12)
120 + 10x = 160
10x = 40
x = 4
To find AB: x + 12; x = 4
AB = x + 2
AB = 4 + 2
AB = 6
8x - 7 = 3x + 9
8x - 3x = 9 + 7
5x = 16
x = 16/5 = 3 1/5
