A cylinder fits inside a square prism as shown. For every cross section, the ratio of the area of the circle to the area of the
kolbaska11 [484]

Answer:

Volume of cylinder = \pi r^2h

Step-by-step explanation:

Given : A cylinder fits inside a square prism.

To find : The volume of cylinder

Solution : Refer the attached graph.

Area of circle = \pi r^2

Area of square = s^2

Side of square = diameter of circle= D^2

Diameter = 2r

∴ Area of square=  2r^2=4r^2

\frac{Area of circle}{Area of Square}=\frac{\pi r^2}{4r^2}=\frac{\pi}{4}

Area of circle is \frac{\pi }{4}  of area of square.

Volume is always = area × height

Volume of prism = Area of square × h = 4r^2h

Volume of cylinder = Area of circle × h = \pi r^2h

Now, rate

\frac{Volume of cylinder}{Volume of prism}=\frac{\pi r^2h}{4r^2h}=\frac{\pi}{4}

⇒Volume of cylinder is  \frac{\pi }{4}  of Volume of prism.

Volume of Cylinder =\frac{\pi }{4}\times Volume of prism

Volume of cylinder = \frac{\pi }{4}\times 4r^2h

Volume of cylinder = \pi r^2h

The market price for a freezer was $4200. A man bought the freezer on hire purchase. He made a deposit of $1350 and twelve month
Oksanka [162]

The amount that would be saved is $330, the amount earns weekly is $170, and the worth of a $250 deposit after 2 years is $270.40.

<h3>How do we calculate the amount saved, weekly wage, and future value?</h3>

The amount that would be saved if he had bought the freezer at the market price can be calculated as follows:

Total amount paid = Deposit + (Monthly payment * 12) = $1,350 + ($265 * 12) = $4,530

Amount that would have been saved = Total amount paid - Market price = $4,530 - $4,200 = $330

The amount the man earns each week can be calculated as follows:

Amount earns weekly = Take home pay / (100% - Tax rate) = $122.40 / (100% - 28%) = $170

The worth of a $250 deposit after 2 years of compound interest can be calculated using the future value (FV) formula as follows:

FV = PV * (1 + r)^n ..................... (1)

Where:

FV = future value or the worth of a $250 deposit after 2 years = ?

PV = present value or deposit = $250

r = interest rate per annum = 4% = 0.04

n = number of years = 2

Substituting all the relevant values into equation (1), we have:

FV = $250 * (1 + 0.04)^2 = $270.40

The function g(x) = x2 is transformed to obtain function h:
Paladinen [302]

Answer:

"The graph of his the graph of g horizontally shifted left 7 units." Which is option "B" n the list

Step-by-step explanation:

If  the function g(x)=x^2  is transformed to obtain the function h(x)=g(x+7), then a transformation that affects the x-variable has taken place.

Recall that a transformation that adds t units to the variable "x" represent graphically the horizontal displacement of the original function,"t" units to the left.

Therefore, the correct answer is:

"The graph of his the graph of g horizontally shifted left 7 units."

which agrees with option "B" in your given list.

An assembled product is built by 10 worker who coordinate their task. A total of 100 units will be made. Time records indicate t
Brut [27]

Answer:

a) 86%

b) 2nd unit = 82 hs.

3rd unit = 75 hs

c) 100th unit = 36 hs

Step-by-step explanation:

We can model the learning curve for manufacturing the units as:

t=aX^b

where t is the time for the Xth unit, and a and b are parameters that we will calculate from the data,

We know that t(1)=95. Then, we have:

t(1)=a\cdot 1^b=95\\\\a=95

And we know that the fourth unit (X=4) take 71 hours to be completed (t(4)=71). Then, we can calculate the other parameter as:

t(4)=95\cdot4^b=71\\\\4^b=71/95\approx 0.7473\\\\b\cdot ln(4)=ln(0.7473)\\\\b=ln(0.7473)/ln(4)=-0.291/1.386\\\\b=-0.21

We have the model for the learning curve:

t=95X^{-0.21}

The learning rate percentage is calculated from the b parameter:

b=\dfrac{ln(LRP)}{ln(2)}=-0.21\\\\\\ln(LRP)=-0.21*ln(2)=-0.21*0.693=-0.1455\\\\LRP=e^{-0.1455}=0.86

The learning rate percentage is 86%.

b) The most likely times required for the 2nd and 3rd units are calculated with the model:

t(2)=95\cdot2^{-0.21}=95*0.864=82\\\\t(3)=95\cdot3^{-0.21}=95*0.794=75

c) If we use the model to calculate the time required for the 100th unit, we have:

t(100)=95\cdot100^{-0.21}=95*0.38=36
