Answer:
EG = 19
Explanation:
Given that a line segment CD. EF bisects the line CD at point G.
Length of CG = 5x-1
Length of GD = 7x - 13
We know that CG = GD
5x-1 = 7x-13
Solve for x,
2x = 12
x = 6
Now given that,
EF = 6x-4
GF = 13
EF = EG + GF
6x - 4 = EG + 13
EG = 6x - 4 - 13
EG = 6x - 17
put the value of x = 6, in order to find the EG
EG = 6*6 - 17
EG = 19
That's the final answer.
I hope it will help you.
Answer: sin pi/4 sin pi/6 = 1/2(cos pi/12 - cos 5pi/12)

Answer:
<em><u>The final atmospheric pressure is 5.19 · 10⁴ Pa</u></em>
Step-by-step explanation:
Assuming that the temperature of the air does not change, we can use Boyle's law, which states that for a gas kept at constant temperature, the pressure of the gas is inversely proportional to its volume. In formula,
pV = const.
where p is the gas pressure and V is the volume
The equation can also be rewritten as
p₁ V₁ = p₂ V₂
where in our problem we have:
p₁ = 1.03 · 10₅ Pa is the initial pressure (the atmospheric pressure at sea level)
V₁ = 90.0L is the initial volume
p₂ is the final pressure
V₂ = 175.0L is the final volume
Solving the equation for p2, we find the final pressure:
p₂ = p₁ v₁ divided by V₂ = (1.01 · 10⁵)(90.0) divided by 175.0 = 5.19 · 10⁴ Pa
