Answer: 4
Step-by-step explanation:
The procedure is pretty basic. First you have to substitute what you know in the equation. So as you know f(x)=18, just substitute f(x) by 18, leaving it like 18 = 3x + 6.
Then you have to start to move things around. First start with the + 6 that is adding, so it moves to the other side as a substraction giving 18 - 6 = 3x -> 12 = 3x. The next step is to get rid of that 3, so because it's multiplying the x, it moves to the other side as a division leaving you with 12 ÷ 3 = x -> 4 = x. There you have the answer! For a value/y of 18 in that function, the x is 4
Answer:
C) It helps reduce carbon dioxide emissions
Step-by-step explanation:
- Methane being a vital greenhouse gas and produces 84 times more heat than carbon dioxide, its concentration varies across the seasons and can remain in the atmosphere for a period of 12 years.
- Methane has the ability to stay in the atmosphere without the oxygen for a longer duration.
- The gas can produce water vapor through the chemical reaction when it reaches the mesosphere and is most likely to produce clouds.
- <u>The environmental benefits of this gas is that it can produce energy by mass and are more refined than oil and creates less pollution and pollutants.</u>

Answer:
D. [0,pi/2]
Step-by-step explanation:
when Ф = 0 in radian
r²= 4cos (2(0))
r² = 4 * 1
r² = 4
∴ r = √4 = 2
r = 2.
when Ф = π/2 in radian
r²= 4cos (2(π/2))
r² = 4 * -1
r² = -4
∴ r = 0
