Answer:
or 
Step-by-step explanation:
we know that
The general equation of a horizontal parabola open to the left is equal to
where
(h,k) is the vertex of the parabola
p is the focal distance (distance from the vertex to the focus)
In this problem we have
The vertex is the point (2,-4)
so
The Focus is the point F(1,-4)
so
the focal distance p=2-1=1 ---> distance from the vertex to the focus
substitute in the formula
<span>The pressure, P, of a gas, varies inversely with its volume, V
</span>
∴ PV = k where k is constant
<span>The pressure is 84 Pa at a volume of 36 L.
</span>
<span>∴ at P = 84 ⇒⇒⇒ V = 36
</span>
<span>∴ K = PV = 84 * 36 = 3,024 ⇒⇒(1)</span>
If the volume is expanded to 216 L, what will the new pressure be?
We need to find P at V = 216
From the equation (1) ⇒⇒⇒ PV = 3024
substitute with V = 216
∴ 216 P = 3024
∴ P = 3024/216 = 14
The correct answer is option <span>B. 14 Pa</span>
