Answer:
8y = -6
Step-by-step explanation:
x + 6y -x +2y = 9 +(-15) ➡ 8y = -6
15) factor out cos: cos(x)(sin(x)+1)=0
Now this is true when either cos(x)=0 (x=pi/2 and 3pi/2)
Or when sin(x)=-1 (x=3pi/2)
So it's solutions are pi/2 and 3pi/2
7/4 and 3 because they are positive
THe problem is basically telling us: 
where P is the power disappated and V^2 is our voltage squared.
So, for the second example to find the power we simply have to plug k and our voltage back in, so:
Answer: 7/24
Step-by-step explanation:
Five-eighths means 5/8
One-third means 1/3
The difference between 5/8 and 1/3 is
5/8 - 1/3 = 7/24
Therefore, the smallest number of equally sized pieces each fraction bar can be broken into 7/24
