Which function has a range of {y|y ≤ 5}? f(x) = (x – 4)2 5 f(x) = –(x – 4)2 5 f(x) = (x – 5)2 4 f(x) = –(x – 5)2 4

Lorico [155]

The function range of {y|y ≤ 5} is f(x)=-(x-4)^4+5.

Since the range has less than a sign, this means that the parabola is

facing downwards and it means that a is negative.

The range is given by

${y|y \leq k}$

<h3>What is the vertex form of a quadratic equation?</h3>

$f(x)=a(x-h)^2+K$

Since the range is

${y|y \leq 5},$

This means that k = 5 , and since a is negative

The correct function is

$f(x)=-(x-4)^4+5$

Schweser Satellites Inc. produces satellite earth stations that sell for $115,000 each. The firm's fixed costs, F, are $3 millio

ExtremeBDS [4]

The incremental profit is $175,000 and the new situation would obviously have less business risk than the old one.

<h3>Incremental profit</h3>

First step

Profit $600,000

Add Fixed cost $3,000,000

Contribution $3,600,000

Variable Cost=Total Sales−Contribution

Variable Cost=$115,000×50-$3,600,000

Variable Cost=$2,150,000

Second step

Profit at revised cost

Sales $8,625,000

(75x $115,000)

Less: Variable cost $4,350,000

[75×($3,000,000+$500,000/50-$12,000)]

Contribution $4,275,000

Less Fixed cost $3,500,000

($3,000,000+$500,000)

Profit $775,000

Incremental profit=Profit at revised cost-Existing profit

Incremental profit=$775,000-$600,000

Incremental profit=$175,000

Expected rate of return=Incremental profit/Investment

Expected rate of return=$175,000/$4,000,000×100

Expected rate of return=$4.375%

2. Break-even point

Existing

Break-even point=Fixed cost/Contribution

Break-even point=$3,000,000/[($115,000-($3,000,000+$500,000/50)]

Break-even point=$3,000,000/[($115,000-$70,000)

Break-even point= 66.67

Revised

Break-even point=Fixed cost/Contribution

Break-even point=$3,500,000/[($110,000-($3,000,000/50)]

Break-even point=$3,000,000/[($110,000-$60,000)

Break-even point=60

II. The new situation would obviously have less business risk than the old one.

one interior angle of a polygon is equal to 800 and each of the other interior angles are 128 degrees. Find the number of sides

KiRa [710]

Answer:

Step-by-step explanation:

Given information:

Interior angle of a polygon cannot be more that 180°.

One interior angle = $80^{\circ}$

Other interior angles are = $128^{\circ}$

Let n be the number of sides of the polygon.

Sum of interior angles is

$Sum=80+128(n-1)$

$Sum=80+128n-128$

Combine like terms.

$Sum=128n-48$ .... (1)

If a polygon have n sides then the sum of interior angles is

$Sum=(n-2)180$

$Sum=180n-360$ .... (2)

Equating (1) and (2) we get

$180n-360=128n-48$

Isolate variable terms.

$180n-128n=360-48$

$52n=312$

Divide both sides by 52.

$n=\frac{312}{52}$

$n=6$

Therefore the number of sides of the polygon is 6.
