How does a software developer differ from a computer programmer?

yan [13]

Answer:

D. A software developer requires leadership skills.

Explanation:

A computer programmer takes care of writing code to create a program.

A software developer takes care of all the process for developing a software and they will define the requirements for a software and then, work with programmers that write the code.

According to that, a software developer differ from a computer programmer because a software developer requires leadership skills as they will have to supervise all the process to create a program and work with people.

raketka [301]

Answer:

The correct answer is Unemployed

Explanation:

Unemployment, in the labor market, refers to the situation of the citizen who lacks employment and, therefore, salary. By extension, it is the part of the population of age, conditions and willingness to work - active population - that lacks a job.1 To refer to the number of unemployed people in the population, the unemployment rate by country or other is used territory. The situation contrary to unemployment is full employment.

In addition to the active population, which includes both those who are working and the whole of the unemployed or unemployed in a country, societies have an inactive population composed of those members of the population who are not willing to work , whether by studies, age, illness or any other legally established cause.

An oil refinery is located on the north bank of a straight river that is 3km wide. A pipeline is to be constructed from the refi

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 />

The taxpayer’s marginal tax bracket is 25%. Which would the taxpayer prefer? a. $1.00 taxable income rather than $1.25 tax-exemp

Zepler [3.9K]

Answer:

option (d) $1.40 taxable income rather than $1.00 tax-exempt income

Explanation:

The taxpayer would prefer option (d) $1.40 taxable income rather than $1.00 tax-exempt income

The above statement will be chosen because in this case the after tax income will be greater than the tax exempt according to the condition given in the question

Given:

Marginal Tax bracket = 25%

thus,

Taxable income = $1.40

Tax = $1.40 × 0.25 = $0.35

Therefore,

The net income = Taxable income - Tax = $1.40 - $0.35 = $1.05

and,

$1.05 > $1.00
