The radius of a cylinder is increasing at a constant rate of 2 inches per minute. The volume remains a constant 440 cubic inches. At the instant when the radius of the cylinder is 44 inches, what is the rate of change of the height? The volume of a cylinder can be found with the equation V= [tex]\pi r^2h[/tex] Round your answer to three decimal places.

Answers

Answer:

The rate of change of the height is approximately [tex]-6.577\times 10^{-3}\,\frac{in}{min}[/tex].

Step-by-step explanation:

From Geometry we know that volume of cylinder ([tex]V[/tex]), measured in cubic inches, is expressed by:

[tex]V = \pi\cdot r^{2}\cdot h[/tex] (1)

Where:

[tex]r[/tex] - Radius, measured in inches.

[tex]h[/tex] - Height, measured in inches.

Given that volume remains constant, the expression for the rate of change of the height ([tex]\dot h[/tex]), measured in inches per minute, is:

[tex]2\pi\cdot r \cdot h \cdot \dot r + \pi \cdot r^{2}\cdot \dot h = 0[/tex]

[tex]2\cdot h\cdot \dot r + r\cdot \dot h = 0[/tex]

[tex]r\cdot \dot h = -2\cdot h \cdot \dot r[/tex]

[tex]\dot h = -\frac{2\cdot h\cdot \dot r}{r}[/tex]

[tex]\dot h = - \left(\frac{2\cdot \dot r}{r}\right)\cdot \left(\frac{V}{\pi\cdot r^{2}} \right)[/tex]

[tex]\dot h = -\frac{2\cdot \dot r \cdot V}{\pi\cdot r^{3}}[/tex] (2)

Where [tex]\dot r[/tex] is the rate of change of the radius, measured in inches per minute.

If we know that [tex]r = 44\,in[/tex], [tex]\dot r = 2\,\frac{in}{min}[/tex] and [tex]V = 440\,in^{3}[/tex], then the rate of change of the height is:

[tex]\dot h = - \frac{2\cdot \left(2\,\frac{in}{min} \right)\cdot \left(440\,in^{3}\right)}{\pi\cdot (44\,in)^{3}}[/tex]

[tex]\dot h \approx -6.577\times 10^{-3}\,\frac{in}{min}[/tex]

The rate of change of the height is approximately [tex]-6.577\times 10^{-3}\,\frac{in}{min}[/tex].

same solution?
A(6x + 8y = -10
2x - 5y = 12
B
8x + 3y = 2
12x + 16y = - 20
A. The first equation in B is the sum of the equations in A, while the other is obtained
by multiplying the second equation in A by 6.
B. The first equation in B is the sum of the equations in A, while the other is obtained
by multiplying the first equation in A by 2.
C. The equations in A are increased by 12 and -32 to get the equations in
D. The equations in A are multiplied by 2 and 4 to get the equations in B.

Answers

Answer:

Correct Answer is B. The first equation in B is the sum of the equations in A, while the other is obtained  by multiplying the first equation in A by 2.

Step-by-step explanation:

As given,

A : 6x + 8y = -10     .......equation (1)

     2x - 5y = 12      .......equation (2)

B : 8x + 3y = 2         .......equation (1)

  12x + 16y = - 20    .......equation (1)

Correct Answer is B. The first equation in B is the sum of the equations in A, while the other is obtained  by multiplying the first equation in A by 2.

Proof :

The first part says that ,

Sum of equation (1) of A and equation (2) of A = Equation (1) of B

Firstly , find the Sum of equation (1) of A and equation (2) of A

⇒6x + 8y + 2x - 5y = -10 + 12

⇒8x + 3y = 2

this is same as equation (1) of B

So, it satisfies the first part

The second part says that,

The equation (2) of B is obtained by multiplying the first equation in A by 2.

It means , if the equation (1) is multiplied by 2 = equation (2) of B

Firstly , if the equation (1) is multiplied by 2 , we get

2 ( 6x + 8y = -10 )

⇒ 2 ( 6x + 8y ) = 2 ( -10)

⇒ 12x + 16y = -20

this is same as equation (2) of B

So, it satisfies the second part.

Jenna earns $8 each week by completing chores. She already has $12 in her savings. How much will she have after 4 weeks?


y = 8x + 4


y = 8x


y = 8x + 12

Answers

Answer:

Option C is the correct answer.

Step-by-step explanation:

Per week earning = $8

Amount in savings = $12

y = Total amount

x = Number of weeks

y = 8x + 12

Where we can put x=4 to calculate earning of 4 weeks.

y = 8(4) + 12

y = 32 + 12 = $44

Therefore,

Option C is the correct answer.

Mrs.Giblin begins hiking at mile marker 25 on the Appalachian Trail and hikes 3 miles every hour. What is the slope?

Answers

Answer:

3 miles

Step-by-step explanation:

Slope is simply the change in position per unit rate. We could conclude that the steepness of the Applachian is the rate of change in position per unit time. Since the distance hiked on the Applachian is said to be 3 miles per hour, then we can conclude that the slope of the applachian is 3 miles

This is the change in miles / change in time.

Chang in miles = 3

Change in time = 1

Slope = 3/1

Slope = 3

How many solutions does 3(x + 5) – 3 = 2(3x + 1) – 3x have? Show your work.

Answers

Answer: There are no solution

Step 1: Simplify both sides of the equation.

3(x+5)−3=2(3x+1)−3x

(3)(x)+(3)(5)+−3=(2)(3x)+(2)(1)+−3x(Distribute)

3x+15+−3=6x+2+−3x

(3x)+(15+−3)=(6x+−3x)+(2)(Combine Like Terms)

3x+12=3x+2

3x+12=3x+2

Step 2: Subtract 3x from both sides.

3x+12−3x=3x+2−3x

12=2

Step 3: Subtract 12 from both sides.

12−12=2−12

0=−10

After solving the equation, the value obtained for x is 0, which means that there is no solution for the equation.

Team Green and Team Blue play in a competition. Team Green has twelve more points than Team Blue.
Team Green has four times as many points as Team Blue.
How many points does each team have?​

Answers

Answer:

Team blue points = 4 points

Team green points = 16 points

Step-by-step explanation:

Let

Team blue points = x

Team green points = (x + 12) points (1)

Team green points = 4x (2)

Equate equation (1) and (2)

x + 12 = 4x

12 = 4x - x

12 = 3x

x = 12/3

x = 4 points

Team blue points = x

= 4 points

Team green points = (x + 12)

= 4 + 12

= 16 points

Team green points = 4x

= 4(4)

= 16 points

When day comes, we ask ourselves, where can we find light in this never-ending shade?The loss we carry. A sea we must wade.We braved the belly of the beast.Weve learned that quiet isnt always peace, and the norms and notions of what just is isnt always justice.And yet the dawn is ours before we knew it.Somehow we do it.Somehow we weathered and witnessed a nation that isnt broken, but simply unfinished.We, the successors of a country and a time where a skinny Black girl descended from slaves and raised by a single mother can dream of becoming president, only to find herself reciting for one.And, yes, we are far from polished, far from pristine, but that doesnt mean we are striving to form a union that is perfect.We are striving to forge our union with purpose.To compose a country committed to all cultures, colors, characters and conditions of man.And so we lift our gaze, not to what stands between us, but what stands before us.We close the divide because we know to put our future first, we must first put our differences aside.We lay down our arms so we can reach out our arms to one another.We seek harm to none and harmony for all.Let the globe, if nothing else, say this is true.That even as we grieved, we grew.That even as we hurt, we hoped.That even as we tired, we tried.That well forever be tied together, victorious.Not because we will never again know defeat, but because we will never again sow division.Scripture tells us to envision that everyone shall sit under their own vine and fig tree, and no one shall make them afraid.If were to live up to our own time, then victory wont lie in the blade, but in all the bridges weve made.That is the promise to glade, the hill we climb, if only we dare.Its because being American is more than a pride we inherit.Its the past we step into and how we repair it.Weve seen a force that would shatter our nation, rather than share it.Would destroy our country if it meant delaying democracy.And this effort very nearly succeeded.But while democracy can be periodically delayed, it can never be permanently defeated.In this truth, in this faith we trust, for while we have our eyes on the future, history has its eyes on us.This is the era of just redemption.We feared at its inception.We did not feel prepared to be the heirs of such a terrifying hour.But within it we found the power to author a new chapter, to offer hope and laughter to ourselves.So, while once we asked, how could we possibly prevail over catastrophe, now we assert, how could catastrophe possibly prevail over us?We will not march back to what was, but move to what shall be: a country that is bruised but whole, benevolent but bold, fierce and free.We will not be turned around or interrupted by intimidation because we know our inaction and inertia will be the inheritance of the next generation, become the future.Our blunders become their burdens.But one thing is certain.If we merge mercy with might, and might with right, then love becomes our legacy and change our childrens birthright.So let us leave behind a country better than the one we were left.Every breath from my bronze-pounded chest, we will raise this wounded world into a wondrous one.We will rise from the golden hills of the West.We will rise from the windswept Northeast where our forefathers first realized revolution.We will rise from the lake-rimmed cities of the Midwestern states.We will rise from the sun-baked South.We will rebuild, reconcile, and recover.And every known nook of our nation and every corner called our country, our people diverse and beautiful, will emerge battered and beautiful.When day comes, we step out of the shade of flame and unafraid.The new dawn balloons as we free it.For there is always light, if only were brave enough to see it.If only were brave enough to be it.
