Social mobility in the u.s. does not depend on where one starts in the class system anthropolgy

alexgriva [62]

The statement above is TRUE.
Social mobility refers to the movement of individuals or families within or between social strata in a particular society. It means a change in social status relative to one's present location with a given society. Social mobility in US does not depend on where one start in the class system; one can come from the lowest class strata and become one of the richest individual and an individual from a very rich family can also end up as a p.auper. A lot of factors come to play in these situations.

Mariulka [41]

Answer:

$6,598,076.21

Explanation:

<h2>THE KEY IS TO FIND OUT THE COST FUNCTION, the calculations are very easy!!!</h2><h2></h2><h3>In order to find the cost function, take a look at the drawing attached. </h3>

We can see the river (sort of) that is 3 km wide and the storage tanks on the other side of the river 8 km apart.

<h3 />

Laying pipes under (across) the river costs 1,000,000 the km & laying pipes over land costs 500,000 per km.

<h3 /><h3>So basically the cost function is 1,000,000 multiplied by something plus 500,000 multiplied by another something.</h3><h3 />

The distance across the river can be found by using Pythagoras Theorem. A side is 3 km the other is unknown, so we call it X. And it is equal to:

$\sqrt{3^{2} +x^{2}}=\\\sqrt{9 +x^{2}}$

And we multiply it by 1,000,000; the cost of laying pipe under the river, the we get:

$1000000\sqrt{9+x^{2}$

The distance over the land is (8-x), as we can see in the drawing. So we multiply it by its cost, 500,000. And we get 500,000(8-x).

So the cost function f(x) would be:

$f(x)=1000000\sqrt{9+x^{2}} + 500000(8-x)$

<h2>From here, we just have to differentiate and the derivative found must be equal to zero in order to minimize cost. </h2><h3>The value of x when the derivative is zero is plugged in the original function to get the cost.</h3><h3 /><h2>LET'S DO THIS</h2>

$f(x)=1000000\sqrt{9+x^{2}} + 500000(8-x)\\f(x)=1000000(9+x^{2})^{1/2}+4000000-500000x\\f'(x)=\frac{1}{2} 1000000(9+x^{2})^{-1/2}(2x)-500000\\\\f'(x)=\frac{1000000x}{\sqrt{9+x^2}} - 500000$

$f'(x)=\frac{1000000x}{\sqrt{9+x^2}} - 500000=0\\\frac{1000000x}{\sqrt{9+x^2}} = 500000\\\frac{2x}{\sqrt{9+x^2}} = 1\\2x={\sqrt{9+x^2}}\\4x^2=9+x^2\\3x^2=9\\x^2=3\\x=\sqrt{3} \\$

And we plug square root of 3 in the original cost function ad we get

$f(\sqrt{3} )=1000000\sqrt{9+x^{2}} + 500000(8-x)\\f(\sqrt{3})=1000000\sqrt{9+(\sqrt{3} )^{2}} + 500000(8-(\sqrt{3}))\\f(\sqrt{3})=1000000\sqrt{9+3} + 500000(8-(\sqrt{3}))\\f(\sqrt{3})=1000000\sqrt{12}+500000(6.27)\\f(\sqrt{3})=1000000(3.46)+500000(6.27)\\f(\sqrt{3})=3464101.62+3133974.60\\f(\sqrt{3})=6598076.21\\$

<h2>so the minimal cost is $6,598,076.21</h2><h2 /><h3 />

Best Buy Co, Inc., is a leading retailer specializing in consumer electronics. A condensed income statement and balance sheet fo

IRISSAK [1]

Answer

A)=1.47655 times

B)0.74 times

C)1.94 times

D)26.2 times

Explanation

The formulas and calculations are shown below:

1-A)the current ratio for Best Buy for its fiscal year ended January 28, 2017.

= Total Current assets ÷ total current liabilities=[10516 ÷ 7122]

=1.47655

1-B)the acid-test ratio for Best Buy for its fiscal year ended January 28, 2017 can be calculated below as

Quick assets = Cash and cash equivalents + short-term investments + Accounts receivable (net)

=2240 + 1681 + 1347=5268

the current liabilities = 7122

If we substitute the values into the above expresion, we have

=$ 5652 ÷ $7122

= 0.74 times

1-C.) the debt to equity ratio for Best Buy for its fiscal year ended January 28, 2017.

Debt equity ratio = (Total debt ÷ Shareholders’ Equity)

where,

Total debt = Total current liabilities + Long-term liabilities

Total current liabilities =$ 9147

the Shareholders’ equity is $4709

If we substitute the values we have,

$9147 ÷$ 4709

= 1.94 times

1-D. Calculate the times interest earned ratio for Best Buy for its fiscal year ended January 28, 2017 can be calculated as

Times interest earned ratio = (Earnings before interest and taxes) ÷ (Interest expense)

Earnings before interest and taxes = Income before income tax + Interest expense + income tax expense

$1854 - $38 + $72

=$1888

Interest expense=$72

Then substitute into above expresion, we have

=$ 1888 ÷$ 72

= 26.2 times
