10.The volume V of a given mass of gas varies inversely as the pressure P. When V =2m3 ,P=500 N/m2 .Find the volume when the pressure is 400N/m2 Find the pressure when the volume is 5 m3

Answers

Answer:

[tex]2.5\; \rm m^3[/tex].

Step-by-step explanation:

Let [tex]V_1[/tex] and [tex]P_1[/tex] denote the volume and pressure of this gas before the change. Let [tex]V_2[/tex] and [tex]P_2[/tex]denote the pressure of this gas after the change.

The ratio between the volume of this gas before and after the change would thus be [tex]\displaystyle \frac{V_1}{V_2}[/tex].

The ratio between the pressure of this gas before and after this change would be [tex]\displaystyle \frac{P_1}{P_2}[/tex].

Because the volume of a given mass of (ideal) gas varies inversely with pressure, these two ratios should be reciprocal of each other. That is:

[tex]\displaystyle \frac{V_1}{V_2} = \frac{1}{\displaystyle \displaystyle \left(\frac{P_1}{P_2}\right)}[/tex].

In other words:

[tex]\displaystyle \frac{V_1}{V_2} = \frac{P_2}{P_1}[/tex].

Rearrange and solve for [tex]V_2[/tex], the volume of this gas after the change:

[tex]\displaystyle V_1 = V_2\cdot \left(\frac{P_2}{P_1}\right)[/tex].

[tex]V_2 = \displaystyle V_1 \cdot \left(\frac{P_1}{P_2}\right)[/tex].

From the question:

Volume of this gas before the change: [tex]V_1 = 2\; \rm m^3[/tex].Pressure of this gas before the change: [tex]P_1 = 500\; \rm N \cdot m^{-2}[/tex].Pressure of this gas after the change: [tex]P_2 = 400\; \rm N \cdot m^{-2}[/tex].

Solve for [tex]V_2[/tex]:

[tex]\begin{aligned} V_2 &= V_1 \cdot \left(\frac{P_1}{P_2}\right) \\ &= 2\; \rm m^3 \times \frac{500\; \rm N \cdot m^{-2}}{400\; \rm N \cdot m^{-2}} = 2.5\; \rm m^3\end{aligned}[/tex].

The point is on the x acis and 12 units to the left of y axis

Answers

Answer:

(-12, 0)

Step-by-step explanation:

They are asking for the coordinates of the given point on the plane.

Therefore, since the point is on the x axis, we know that its y-coordinate must be zero. y = 0

Now, since it is 12 units to the left of the y axis, then its x coordinate is -12

x = -12

Therefore, the point in plane coordinates is written as: (-12, 0)

Please help with this two part question (Calculus)^^

Answers

Answer:

1) -0.016 pounds per square inch per cubic inch.

2) [tex]\displaystyle V'(P)=-\frac{800}{P^2}[/tex]

Step-by-step explanation:

We are given the equation [tex]PV=800[/tex].

Part A)

We want to determine the average rate of change of P as V increases from 200 cubic inches to 250 cubic inches.

To find the average rate of change between two points, we find the slope between them.

Rewrite the given equation as a function of V:

[tex]\displaystyle P(V)=\frac{800}{V}[/tex]

Hence, the average rate of change for V = 200 and V = 250 is:

[tex]\displaystyle \begin{aligned} m &= \frac{P(250) - P(200)}{250 - 200} \\ \\ & = \frac{3.2 - 4}{250 - 200} \\ \\ & = -0.016\end{aligned}[/tex]

Therefore, the average rate of change is -0.016 pounds per square inch per cubic inch.

Part B)

We want to express V as a function of P. This can be done through simple division:

[tex]\displaystyle V(P)=\frac{800}{P}[/tex]

We want to show that the instantaneous change of V with respect to P is inversely proportional to the square of P. So, let's take the derivative of both sides with respect to P:  

[tex]\displaystyle \frac{d}{dP}\left[V(P)\right]=\frac{d}{dP}\left[\frac{800}{P}\right][/tex]

Differentiate. Note that 1/P is equivalent to P⁻¹. This allows for a simple Power Rule:

[tex]\displaystyle \begin{aligned} V'(P) & = 800\frac{d}{dP}\left[ P^{-1}\right] \\ \\ & = -800(P^{-2}) \\ \\ & = -\frac{800}{P^2}\end{aligned}[/tex]

Therefore, the instantaneous change of V is indeed inversely proportional to the square of P.

bc = ad

solve for a

Answers

Answer:

[tex]\huge\boxed{a=\frac{bc}{d}}[/tex]

Step-by-step explanation:

In order to find the value of a when we have the equation [tex]bc=ad[/tex], our goal is to isolate a on one side.

The key question here is: what's stopping a from being alone on one side? That would be it being multiplied by [tex]d[/tex]. If we were able to remove the d, we would have a by itself.

Since we are multiplying a and d, we can get rid of the d by dividing both sides by d.

We have to divide both sides of the equation by the same value in order to keep it equal.

[tex]bc \div d = ad \div d\\\\\frac{bc}{d}=a\\\\a = \frac{bc}{d}[/tex]

What is factorise 5y - 10

Answers

Answer:

5(y - 2)

Step-by-step explanation:

What is the GCF (Greatest Common Factor) for 5y and -10? It is 5 so you take  5 out of 5y and 5 out of -10. You put the 5 outside of the parentheses and put y - 2 inside of the parentheses. That is how you factorize 5y - 10

The factorized form of 5y - 10 is 5(y - 2).

What is factorization?

Factorization in mathematics is the process of dividing a large number into smaller ones that when multiplied together, give you the original number. Factorization is the process of dividing a number into its components or divisors.

When we are asked to factorize an expression, we are essentially trying to write the expression as a product of simpler expressions. In this case, we want to write 5y - 10 as a product of simpler expressions.

One way to approach this is to look for a common factor that is present in both terms of the expression.

In this case, we can see that both 5y and 10 are divisible by 5. Therefore, we can factor out the greatest common factor of the two terms, which is 5.

When we factor out 5 from 5y and -10, we are left with:

5y - 10 = 5(y - 2).

Write the equation of line in slope-intercept form.
Line parallel to y=−2x+3 that passes through the point (−100,−100)

Answers

Answer:  y= -2x - 500  

Step-by-step explanation:

Parallel lines have the same slopes but different y-intercepts. This means that the line parallel to y=-2x + 3 will have the same slope which is -2.

We will input the x and y coordinates for the given point into the formula and solve for the y-intercept to write the equation.

-100 = -2(-100) + b      where b is the y-intercept

-100 = 400 + b

-400  -400  

b = -500  

The y intercept is -500 and the slope is -2 therefore, the equation will be  

 y= -2x - 500
