Use long division to determine the quotient of the polynomials. (x3 – 7x – 6) ÷ (x – 4) Which of the following options best describes the relationship between the polynomial division and the remainder? The quotient has a remainder of zero. Therefore, the divisor is a factor of the dividend. The quotient has a remainder of 9. Therefore, the divisor is not a factor of the dividend. The quotient has a remainder of 30. Therefore, the divisor is not factor of the dividend. The quotient has a remainder of 36. Therefore, the divisor is a factor of the dividend.

Answers

Final answer:

Using long division of polynomials, when we divide (x³ - 7x - 6) by (x - 4), the quotient is x² + 4x + 16 with a remainder of -70. This implies that the divisor (x - 4) is not a factor of the dividend (x³ - 7x - 6), since a non-zero remainder exists.

Explanation:

To perform the task, we first note down the dividend (x³ - 7x - 6) and divisor (x - 4). We divide the first term of the dividend by the first term of the divisor to find the first term of the quotient and continue this process as required in polynomial division. Solving this using long division of polynomials, we get:

Dividend: x³ - 7x - 6

Divisor: x - 4

The quotient after performing long division is x² + 4x + 16 and the remainder is -70. This shows that the divisor (x - 4) is not a factor of the dividend (x³ - 7x - 6), since a remainder exists after the division is performed.

So, the correct option is: The quotient has a remainder of -70. Therefore, the divisor is not a factor of the dividend.

Step-by-step explanation:

If the two triangles Δ ABC and ΔDEC are similar then there corresponding sides will be in the same ratio.

Now using this theorem in these triangles

[tex]\frac{AB}{DE}=\frac{BC}{EC}[/tex]

Now it has been given

AB = (4x - 1)

BC = 4

EC = 4

DE = x + 2

By putting these values in the formula

[tex]\frac{4x-1}{x+2}=\frac{4}{4}=1[/tex]

We cross multiply on both the sides

(4x - 1) = (x + 2)

4x - x = 1 + 2

PART A: Maria rented a coat at $285 for 3 days. If she rents the same coat for 60 days, she has to pay a total rent of $510. Write an equation in standard form to represent the total rent (y) that Maria has to pay for renting the coat for x days.
PART B: Write the equation obtained in Part A using function notation.
PART C: Describe the steps to graph the equation obtained above on the coordinate axes. Mention the labels on the axes and the intervals.

Answers

1) Name the variables

Number of days: x

rent: y

2) state the initial points

   x           y
days        $

  3           285

60           510


3) assume linear relation:

=> (y - yo) / (x - xo) = (y1 - yo) / (x1 - xo)

=> (y - 285) / (x - 3) = (510 - 285) / (60 - 3)

=> (y - 285) / (x - 3) = 225 / 57 = 75 / 19

=> 19 (y - 285) = 75 (x - 3)

=> 19y - 19*285 = 75x - 75*3

=> 19y - 75x = 5415 - 225

=> 19y  - 75x = 5190

=> standar form = -75x + 19y = 5190


PART B: Write the equation obtained in Part A using function notation.

-75x + 19y = 5190

=> 19y = 5190 + 75x

=> y = 5190/19 + (75/19)x

=> function notation = f(x) = (75/19)x + 5190 / 19

PART C: Describe the steps to graph the equation obtained above on the coordinate axes. Mention the labels on the axes and the intervals.

1) Coordinate axes:

x: number of days

y: rent

2) draw the two given points: (3,285) and (60, 510)

3) draw the line that joins those points from the interception of the y-axis until some points further (60, 510).

You're at a halloween fair with a big ferris wheel. the wheel has ten chairs and people are seated two per chair. every minute a chair passes the exit platorm. the wheel opens at 11 am for thirty minutes -- how many people took a ride in that time?

Answers

The number of people who took ride in the big ferris wheel at a fair can be calculated by proper dimensional analysis. This can be done through the equation below,

         n = (number of minutes)(rate at which the chair passes the exit platform)(number of persons per chair)

Substituting the known values to the equation,

       n = (30 minutes)(1 chair / minute)(2 persons / chair)
                 n = 60 persons

Answer: 60 persons

The number of persons who have taken the ride is 60.

According to the question, a halloween fair with a big ferris wheel. The wheel has 10 chairs and people are seated [tex]2/chair[/tex].

Mean change is the average change over an entire data set.

The mean change in weight per month is 50 pounds.

What is mean change?

Mean change is the average change over an entire data set.

We have,

The weight of the bear = 500 pounds

After 6 months the weight of the bear = 200 pounds

The change in weight of the bear in 6 months = 300 pounds

We can write it as:

6 months = 300 pounds

We need to find the weight change in one month so we need to make 6 months into 1 month by dividing both sides by 6.

So,

6/6 month = 300/6 pounds

1 month = 50 pounds

Thus the mean change in weight per month is 50 pounds.

Answers

Answer:

B) SAS congruence postulate  

Step-by-step explanation:

We have marked that RN and NQ are congruent.  We also have marked that MN and NP are congruent.

∠MNR≅∠QNP because they are vertical angles.  Vertical angles are opposite angles that share only a vertex; these are vertical angles so they are congruent.

This gives us two sides and an included angle; this is SAS.

B) SAS congruence postulate  proves that △ RNM and △ QNP are congruent

In isosceles ∆DEK with base DK, EF is the angle bisector of ∠E, m∠DEF = 43°, and DK = 16cm. Find: KF, m∠DEK, m∠EFD.

Answers

we have isosceles ∆DEK 

EF is the angle bisector of ∠E,
 m∠DEF = 43°=  m∠FEK ( the bisector divide the angle in two equal angles)

so m∠DEK = m∠DEF +  m∠FEK = 43 + 43 = 86 

∆DEK  is isoceles triangle (given)
the two base angles are equal m∠EDK =  m∠DKE 
and the sum of angles in a triangle = 180

so m∠DEK  + m∠EDK+ m∠DKE = 180 
86  +  m∠EDK+ m∠DKE =  180 

2  x  m∠EDK = 94 

m∠EDK  = 94 / 2 = 47 

in triangle DEF 
m∠EDF + m∠E FD+m∠FED= 180

47 +m∠E FD + 4 3 = 180

m∠E FD = 180-43-47 =  90

 
Find: KF?
in an isoseles triangle the bisector is in the same time median so 
KF= DK / 2 =  16/ 2 = 8 cm

What are the domain and range of the function?

The domain of the function includes all possible x values of a function, and the range includes all possible y values of the function.

The expression is given in the question as

(h² + 3h −10) / (h² − 12h + 20)

(h² + 5h - 2h−10) / (h² − 10h - 2h + 20)

(h(h + 5) - 2(h+5)) / (h(h − 10) - 2(h - 10))

(h + 5)(h - 2) / (h − 10)(h - 2)

We know that the denominator cannot be zero

Here (h-2)(h-10)=0

h= 2 or h = 10

Therefore, h cannot be 2 or 10 i.e. in the notation h≠2 and h≠10.

The domain restrictions of the expression (h² + 3h −10) / (h² − 12h + 20) are
