If the polynomial

Mathematics
1 answer:
erik [133]3 years ago
3 0

Answer:

  • (C) - x

Step-by-step explanation:

<u>Given polynomial:</u>

  • x¹⁹ + x¹⁷ + x¹³ + x⁷ + x⁵ + x³

<u>Group as follows:</u>

  • (x¹⁹ + x¹⁷) + (x¹³ + x¹¹) + (x⁷ + x⁵) + (x³ + x) - x =
  • x¹⁷(x² + 1) + x¹¹(x² + 1) + x¹⁵(x² + 1) + x(x² + 1) - x

As we see all terms have (x² + 1) as factor apart from the last one.

It means the remainder is - x

Correct choice is C

A box contains 6 black socks and 4 red socks. What is the probability of picking two black socks from the bag without replacemen
bazaltina [42]

Answer:

9/25

Step-by-step explanation:

Our box contains 10 socks. (6, which are black and 4 which are red)

Probability of picking 1 black sock will be 6/10

Number of ways it can occur / Total number of outcomes.

In this question we pick two socks, one black firstly and another black, in the second turn. When we say AND, it means intersection

P (B₁ ∩ B₂) = 6/10 . 6/10

When the events are independent, the probability of the intersection will be the product of the probabilities,

P (B₁ ∩ B₂) = 36/100 = 9/25

Hector used the quadratic formula to solve the polynomial equation

Answer:

STEP

:

Equation at the end of step 1

 (32x2 -  8x) -  2  = 0

STEP

2

:

Trying to factor by splitting the middle term

2.1     Factoring  9x2-8x-2

The first term is,  9x2  its coefficient is  9 .

The middle term is,  -8x  its coefficient is  -8 .

The last term, "the constant", is  -2

Step-1 : Multiply the coefficient of the first term by the constant   9 • -2 = -18

Step-2 : Find two factors of  -18  whose sum equals the coefficient of the middle term, which is   -8 .

     -18    +    1    =    -17

     -9    +    2    =    -7

     -6    +    3    =    -3

     -3    +    6    =    3

     -2    +    9    =    7

     -1    +    18    =    17

Observation : No two such factors can be found !!

Conclusion : Trinomial can not be factored

 9x2 - 8x - 2  = 0

Parabola, Finding the Vertex:

3.1      Find the Vertex of   y = 9x2-8x-2

Parabolas have a highest or a lowest point called the Vertex .   Our parabola opens up and accordingly has a lowest point (AKA absolute minimum) .   We know this even before plotting  "y"  because the coefficient of the first term, 9 , is positive (greater than zero).

Each parabola has a vertical line of symmetry that passes through its vertex. Because of this symmetry, the line of symmetry would, for example, pass through the midpoint of the two  x -intercepts (roots or solutions) of the parabola. That is, if the parabola has indeed two real solutions.

Parabolas can model many real life situations, such as the height above ground, of an object thrown upward, after some period of time. The vertex of the parabola can provide us with information, such as the maximum height that object, thrown upwards, can reach. For this reason we want to be able to find the coordinates of the vertex.

For any parabola,Ax2+Bx+C,the  x -coordinate of the vertex is given by  -B/(2A) . In our case the  x  coordinate is   0.4444  

Plugging into the parabola formula   0.4444  for  x  we can calculate the  y -coordinate :

 y = 9.0 * 0.44 * 0.44 - 8.0 * 0.44 - 2.0

or   y = -3.778

Parabola, Graphing Vertex and X-Intercepts :

Root plot for :  y = 9x2-8x-2

Axis of Symmetry (dashed)  {x}={ 0.44}

Vertex at  {x,y} = { 0.44,-3.78}

x -Intercepts (Roots) :

Root 1 at  {x,y} = {-0.20, 0.00}

Root 2 at  {x,y} = { 1.09, 0.00}

Solve Quadratic Equation by Completing The Square

3.2     Solving   9x2-8x-2 = 0 by Completing The Square .

Divide both sides of the equation by  9  to have 1 as the coefficient of the first term :

  x2-(8/9)x-(2/9) = 0

Add  2/9  to both side of the equation :

  x2-(8/9)x = 2/9

Now the clever bit: Take the coefficient of  x , which is  8/9 , divide by two, giving  4/9 , and finally square it giving  16/81

Add  16/81  to both sides of the equation :

 On the right hand side we have :

  2/9  +  16/81   The common denominator of the two fractions is  81   Adding  (18/81)+(16/81)  gives  34/81

 So adding to both sides we finally get :

  x2-(8/9)x+(16/81) = 34/81

Adding  16/81  has completed the left hand side into a perfect square :

  x2-(8/9)x+(16/81)  =

  (x-(4/9)) • (x-(4/9))  =

 (x-(4/9))2

Things which are equal to the same thing are also equal to one another. Since

  x2-(8/9)x+(16/81) = 34/81 and

  x2-(8/9)x+(16/81) = (x-(4/9))2

then, according to the law of transitivity,

  (x-(4/9))2 = 34/81

We'll refer to this Equation as  Eq. #3.2.1  

The Square Root Principle says that When two things are equal, their square roots are equal.

Note that the square root of

  (x-(4/9))2   is

  (x-(4/9))2/2 =

 (x-(4/9))1 =

  x-(4/9)

Now, applying the Square Root Principle to  Eq. #3.2.1  we get:

  x-(4/9) = √ 34/81

Add  4/9  to both sides to obtain:

  x = 4/9 + √ 34/81

Since a square root has two values, one positive and the other negative

  x2 - (8/9)x - (2/9) = 0

  has two solutions:

 x = 4/9 + √ 34/81

  or

 x = 4/9 - √ 34/81

Note that  √ 34/81 can be written as

 √ 34  / √ 81   which is √ 34  / 9

Solve Quadratic Equation using the Quadratic Formula

3.3     Solving    9x2-8x-2 = 0 by the Quadratic Formula .

According to the Quadratic Formula,  x  , the solution for   Ax2+Bx+C  = 0  , where  A, B  and  C  are numbers, often called coefficients, is given by :

                                   

           - B  ±  √ B2-4AC

 x =   ————————

                     2A

 In our case,  A   =     9

                     B   =    -8

                     C   =   -2

Accordingly,  B2  -  4AC   =

                    64 - (-72) =

                    136

Applying the quadratic formula :

              8 ± √ 136

  x  =    —————

                   18

Can  √ 136 be simplified ?

Yes!   The prime factorization of  136   is

  2•2•2•17

To be able to remove something from under the radical, there have to be  2  instances of it (because we are taking a square i.e. second root).

√ 136   =  √ 2•2•2•17   =

               ±  2 • √ 34

 √ 34   , rounded to 4 decimal digits, is   5.8310

So now we are looking at:

          x  =  ( 8 ± 2 •  5.831 ) / 18

Two real solutions:

x =(8+√136)/18=(4+√ 34 )/9= 1.092

or:

x =(8-√136)/18=(4-√ 34 )/9= -0.203

Two solutions were found :

x =(8-√136)/18=(4-√ 34 )/9= -0.203

x =(8+√136)/18=(4+√ 34 )/9= 1.092
