The pressure, P, of a gas, varies inversely with its volume, V. Pressure is measured in units of Pa. Suppose that a particular a

mount of a gas is initially at a pressure of 84 Pa at a volume of 36 L. If the volume is expanded to 216 L, what will the new pressure be?
A. 6 Pa
B. 14 Pa
C. 216 Pa
D. 504 Pa

<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>

Determine the equation
sergejj [24]

Answer:

y=\frac{3}{4} x-\frac{5}{4}

Step-by-step explanation:

two points on the line are

(-1, -2)

(-5, -5)

The slope:

m=\frac{-2-(-5)}{-1-(-5)} =\frac{-2+5}{-1+5} =\frac{3}{4}

The equation:

with (-1,-2)

y-(-2)=\frac{3}{4} (x-(-1))

y+2=\frac{3}{4} x+\frac{3}{4}

y=\frac{3}{4} x+\frac{3}{4} -\frac{8}{4}

y=\frac{3}{4} x-\frac{5}{4}

Hope this helps

What is the 6th term in the sequence described by the following recursive formula?
larisa86 [58]

Answer:

Correct answer is: D) a₆ = - 11

Step-by-step explanation:

Given:

a₁ = 9 and aₙ = aₙ₋₁ - 4

We know it is

a₆ = a₅ + d also it is given a₆ = a₅ - 4

When we equate the right sides of equality we get:

a₅ + d = a₅ - 4 => d = - 4

We also know it is   a₆ = a₁ + 5 d

Now we will find a₆

a₆ = 9 + 5 (-4) = 9 - 20 = - 11

a₆ = - 11

God with you!!!

What is the solution for -10 &lt; x - 9? x &gt; -19 x &lt; -19 x &gt; -1 x &lt; -1
Sedbober [7]

Answer:

Option C:  x > -1 is the right answer.

Step-by-step explanation:

Given that:

-10 < x - 9--------- eq1

Adding 9 on both sides:

-10  + 9< x - 9 + 9

On left side:

Subtracting positive digit from negative one (greater) will give answer in negative. (-10+9 =-1)

On right side:

Negative 9 will be cancelled by positive 9 and simplified as follows:

-1 < x

OR

x > -1

i hope it will help you!

Maurinko [17]
2t + j = 80
3(0.5)t + 2(0.5)j = 70

j = 80 - 2t
1.5t + j = 70
1.5t + 80 - 2t = 70
-0.5t = 70 - 80
-0.5t = -10
t = -10/-0.5
t = 20

j = 80 - 2t
j = 80 - 2(20)
j = 80 - 40
j = 40

so ur answer is C
