Boyle's Law states that when a sample of gas is compressed at a constant temperature, the pressure P and volume V satisfy the eq
lawyer [7]

Answer:

The value of rate of decrease of volume = - 3600 \frac{k pa}{min}

Step-by-step explanation:

According to Boyle's law P V = C ------- (1)

Pressure ( P ) = 100 k pa = 10 \frac{N}{cm^{2} }

Volume ( V ) = 900 cm^{3}

Put these values in equation ( 1 ) we get,

⇒ C = 10 × 900 = 9000 N-cm = 90 N-m

Differentiate Equation ( 1 ) with respect to time we get,

⇒ V \frac{dP}{dt} + P \frac{dV}{dt} = 0

⇒ V \frac{dP}{dt} = - P \frac{dV}{dt}

⇒ \frac{dV}{dt} = - \frac{V}{P} \frac{dP}{dt} ---------- (2)

This equation gives the rate of decrease of volume.

Given that Rate of increase of pressure = \frac{dP}{dt} = 40 \frac{k pa}{min}

C = 90 N-m

P =  10^{5} pa = 10 \frac{N}{cm^{2} }

V = 900 cm^{3}

Put all the above values in equation 2 we get,

⇒  \frac{dV}{dt} = - \frac{900}{10} × 40

⇒  \frac{dV}{dt} = - 3600 \frac{k pa}{min}

This is the value of rate of decrease of volume.

If there is a 24 foot board cut into 2 pieces and one piece is 4 times longer than the other what are the lengths of each piece
erik [133]
First set up an equation as your approach. I will use the equation x+4x=24 because that way you are saying that something pluse itself times 4 equals 24 which is what you want.

simplify the equation

5x=24

x=24/5

So you know onw piece will be 24/5 of a foot and the ither qould be that times 4 so 96/24 of a foot. In decimals it would be 4.8 and 19.2

Solve for x in the equation:log6-2logx=1.4​
Annette [7]

9514 1404 393

Answer:

  x = (√6)/10^0.7 ≈ 0.488737

Step-by-step explanation:

It can work reasonably well to take antilogs first.

  \log(6)-2\log(x)=1.4\\\\\dfrac{6}{x^2}=10^{1.4}\\\\\dfrac{6}{10^{1.4}}=x^2\\\\x=\dfrac{\sqrt{6}}{10^{0.7}}\approx0.488737

Write an algebraic rule to describe the translation c (5,-4) c'(-2,1)
Sauron [17]
We can solve this by using the formula:
(x, y) (x + a, y + b) = (5,-4) (-2,1)

So, plugging in the values and solving for a and b,
5 + a = -2
a = -8

-4 + b = 1
b = 5

Therefore, the translation is
(x,y) (x - 8, y +5)
