[tex]\cot^4 A - \cot^2 A = 1\\\\\cot^4 A = 1 + \cot^2 A\\\\\frac{\cos^4 A}{\sin^4 A} = 1 + \frac{\cos^2 A}{\sin^2 A}\\\\\frac{\cos^4 A}{\sin^4 A} = \frac{\sin^2 A}{\sin^2 A}+\frac{\cos^2 A}{\sin^2 A}\\\\\frac{\cos^4 A}{\sin^4 A} = \frac{\sin^2 A+\cos^2 A}{\sin^2 A}\\\\\frac{\cos^4 A}{\sin^4 A} = \frac{1}{\sin^2 A}\\\\\cos^4 A = \frac{\sin^4 A}{\sin^2 A}\\\\\cos^4 A = \sin^2 A\\\\[/tex]

This then means,

[tex]\cos^4 A + \cos^2 A = 1\\\\\sin^2 A + \cos^2 A = 1\\\\[/tex]

which is the pythagorean trig identity. This concludes the proof.

Therefore, if [tex]\cot^4 A - \cot^2 A = 1[/tex], then [tex]\cos^4 A + \cos^2 A = 1[/tex]

Pulling out like terms

3.1     Pull out like factors :

  -2x2 - 18x - 40  =   -2 • (x2 + 9x + 20)

Trying to factor by splitting the middle term

3.2     Factoring  x2 + 9x + 20

The first term is,  x2  its coefficient is  1 .

The middle term is,  +9x  its coefficient is  9 .

The last term, "the constant", is  +20

Step-1 : Multiply the coefficient of the first term by the constant   1 • 20 = 20

Step-2 : Find two factors of  20  whose sum equals the coefficient of the middle term, which is   9 .

     -20    +    -1    =    -21

     -10    +    -2    =    -12

     -5    +    -4    =    -9

     -4    +    -5    =    -9

     -2    +    -10    =    -12

     -1    +    -20    =    -21

     1    +    20    =    21

     2    +    10    =    12

     4    +    5    =    9    That's it

Answer:

  D) the point where the graph crosses the y-axis

Step-by-step explanation:

The "initial" value of a function is generally taken to mean the function value when the independent variable is zero.

On a graph of the profit function, that will be the y-intercept: the point where the graph crosses the y-axis.

__

The highest point on the graph will be the maximum profit.

The points where the graph crosses the x-axis will be where profit is zero, referred to as "break-even" points.

The lowest point on the graph will be where the profit is a minimum. That point may actually indicate a loss (negative profit).

Answer:

[tex]y = 3x +1[/tex]

Step-by-step explanation:

We can verify it by substituting the [tex]x[/tex] with the numbers in the [tex]x[/tex] column to get the same [tex]y[/tex] in the [tex]y[/tex] column.

Check:

[tex]y = 3(-2) +1\\y = -6 +1\\y= 5[/tex]

It matches; therefore, the answer is [tex]y = 3x +1[/tex]. You can try with the other equations given and take the same steps, but it will not match.

Answer:

Min is 51 and max is 75 and the the mediem is 63 and the q1 is 54 and q2 is 55 and 57 and q3 is 65 and 69

Step-by-step explanation:

the least is 51 and the most is 75 and the mean is 63 if u list them in order and than u find the quartiles that are between the median and 51 and q3 is between the median and the max.

[tex]\cfrac{(21x^5y^8)^2}{3x^2}\implies \cfrac{((3)(7)x^5y^8)^2}{3x^2}\implies \cfrac{3^2\cdot 7^2x^{5\cdot 2}y^{8\cdot 2}}{3x^2}\implies \cfrac{3^2}{3}\cdot \cfrac{7^2 x^{10} y^{16}}{x^2} \\\\\\ 3\cdot 7^2 x^{10}\cdot x^{-2} y^{16}\implies 3\cdot 49x^{10-2}y^{16}\implies 147x^8y^{16}[/tex]

Step-by-step explanation: I first drew it out on a time line and both buses came back together at 4:24 pm. I also looked at the common denominator was for both numbers, 6 and 8: 24.

To check my answer, I substituted other numbers and found that they came back together again at the LCD. Hope this helps.

Answer:

  ST = 6

Step-by-step explanation:

The segment sum is ...

  QR +RS +ST = QT

  QR +2 +ST = 10 . . . . use given values

Since R is the midpoint of QS, we know QR = RS = 2. Now, we have ...

  ST = 10 -2 -QR = 10 -2 -2 = 6

The length of ST is 6.

Answer:

140 degrees

Step-by-step explanation:

The formula of the hint is the sum of the angles in a nonagon (9 sided polygon). If we divide the sum of the angles in a nonagon by nine we should be able to get the angle of each nonagon.

(9-2) * 180 = 7 * 180 = 1260

1260/9 = 140 degrees

Answer: 16.666666 feet

The tangent or tanθ in a right angle triangle is the ratio of its perpendicular to its base. The Height of the fence is 8 feet.

The tangent or tanθ in a right angle triangle is the ratio of its perpendicular to its base. it is given as,

tan(θ) = Perpendicular/Base

where,

θ is the angle,

Perpendicular is the side of the triangle opposite to the angle θ,

Base is the adjacent smaller side of the angle θ.

Given that a 25-foot tree casts a 6 1/4-foot shadow. Also, At the same time, a fence casts a 2-foot shadow.

Length of the shadow = 6 1/4 feet = 6 + 1/4 = 6.25 feet

Now, since the sun is at the same angle, therefore, the angle between the top of the object and the top of the its shadow will be the same for all the objects. Therefore,

tan(θ) = Height of the tree/Shadow of the tree = Height of the fence/Shadow of the fence

tan(θ) = 25 feet / 6.25 feet =  Height of the fence / 2 feet

Height of the fence = (2feet × 25 feet) / 6.25 feet

Height of the fence = 8 feet

Hence, the Height of the fence is 8 feet.

Well, at first consider the given equation, then will be solving for Part A) and B),

[tex]{:\implies \quad \sf 5+x-14=x-7}[/tex]

Subtracting x from both sides will yield ;

[tex]{:\implies \quad \sf 5-14=-7}[/tex]

[tex]{:\implies \quad \sf -9=-7}[/tex]

But, -9 ≠ -7, so their is no solution for values of x, as -9 can't be equal to -7 , so from definition of algebra, we can say that, their are no solutions for x, as there are no solutions for x, so nothing can be concluded from Part A and Part B

Answer:

Part A: -9 ≠ -7

no solution

Part B: below for the answers

Step-by-step explanation:

Part A: 5 + x - 14 = x - 7

subtract x on both sides

x - 5 + x - 14 = x - 7 - x

then, we take away the x's

5 - 14 = -7

-9 ≠ -7

there is no solution

Part B: 5 + -2 - 14 = -2 - 7

-11 ≠ -9

5 + 0 - 14 = 0 - 7

-9 ≠ -7

5 + 3 - 14 = 3 - 7

-6 ≠ -4

Answer: 254.5

Step-by-step explanation:

Based on the information the amount that Agnes paid as state income tax is $2,040.

Federal Income Tax is the tax system in the United States, levied and governed by Internal Revenue Services (IRS) which helps determine the tax that is charged on the income earned by individuals, corporates, and various other legal entities.

The first step is to calculate Agnes' federal taxable income.

Federal taxable income=$15449.60/0.284

Federal taxable income= $54,400

The second step is to calculate Agnes' state income tax.

State income tax=0.0375 ×$54,400

State income tax=$2,040

Hence, the amount that Agnes paid as state income tax is $2,040.

Thus for each person it may take :

[tex]480 \div 3 = 160 \: \: min[/tex]

And for 5 people it will take :

[tex]160 \times 5 = 800 \: \: min[/tex]

Answer is 780 minutes

2.6 hours = 1 person

8/3 = 2.66 (continuing)

5 x 2.6 = 780 minutes (13 hours)

So, 5 people = 780 minutes
