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:
Step-by-step explanation:
This is an order of operations question. First in PEMDOS you want to do your parenthesis, turn (5-2) into 3,
15 ÷ 3 + 4
Then do your divison, turning 15 ÷ 3 into 5
5 + 4
Then finish with 5 + 4
The answer is 9
Answer:
∠ L ≈ 21.6°
Step-by-step explanation:
Using the Sine rule in the triangle
= 
, that is
= 
( cross- multiply )
42 × sinL = 34 × sin27° ( divide both sides by 42 )
sinL = 
, then
∠ L = 
( ) ≈ 21.6° ( to the nearest tenth )
Answer:
y= 125,000 (1.15x)
Step-by-step explanation:
Hey there!
Do PEMDAS
Parentheses
Exponents
Multiplication
Division
Addition
Subtraction
15 + 2(2 * 4) - 4^2
= 15 + 2(8) - 4^2
= 15 + 16 - 4^2
= 31 - 4^2
= 31 - 4 * 4
= 31 - 16
= 15
Therefore, your answer is: 15
Good luck on your assignment & enjoy your day!
