Answer:

Option C (2.5, 1) is the right alternative.

Step-by-step explanation:

The given points are:

A = (-1, 5) = (x₁, y₁)

B = (6, -3) = (x₂, y₂)

Now,

The midpoint on X-axis is:

= [tex]\frac{x_1+x_2}{2}[/tex]

= [tex]\frac{-1+6}{2}[/tex]

= [tex]\frac{5}{2}[/tex]

= [tex]2.5[/tex]

The midpoint on Y-axis is:

= [tex]\frac{y_1+y_2}{2}[/tex]

= [tex]\frac{5+(-3)}{2}[/tex]

= [tex]\frac{5-3}{2}[/tex]

= [tex]\frac{2}{2}[/tex]

= [tex]1[/tex]

Thus the midpoint of AB is "2.5, 1".

Step-by-step explanation:

we eliminate these two options

because remember quadratic function standard form

[tex] \displaystyle f(x) = {ax}^{2} + bx + c[/tex]

recall that, if

but a is positive so it won't flip upside down therefore,

these two are our answer

it seems good but it's not the answer according to the given condition however it's true for the opposite of the given condition:

it's our answer since the condition x<-2 for the quadratic function tells us everything is input For x which is less than -2 the graph-c as well yields so

likewise the absolute value function. the condition tells everything is input for x which is greater than or equal to -2 the graph also says so

hence our answer is C

[tex]P(x<3.12)= 0.21186[/tex]

Step-by-step explanation:

Mean [tex]\=x=\$3.20[/tex]

Standard deviation [tex]\sigma =\$0.10[/tex]

Estimated price [tex]y=\$3.12[/tex]

Generally the equation for P(x<3.12) is mathematically given by

 [tex]P(x<3.12)=P(\frac{y-x}{\sigma}<-\frac{3.12-3.20}{0.10})[/tex]

 [tex]P(x<3.12)=(z<-0.8)[/tex]

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

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

Step-by-step explanation:

The compliment of the set S is {x|x is a rational non-integer}

The union of two sets A and B is the set of all those elements which are either in A or in B, i.e. A ∪ B, whereas the intersection of two sets A and B is the set of all elements which are common. The intersection of these two sets is denoted by A ∩ B

The union of two sets is a new set that contains all of the elements that are in at least one of the two sets

The intersection of two sets is a new set that contains all of the elements that are in both sets

Given data ,

Let the universal set be represented as U

where the value of U is

U = {x|x is a rational numbers}

And , let the second set be represented as S,

where S = {x|x is an integer}

Now , the compliment of set S is given by = S'

And , S' = 1 - S

On simplifying , we get

S' = 1 - {x|x is an integer} and it belongs to U

So , S' = {x|x is a rational non-integer}

Hence , the set is S' = {x|x is a rational non-integer}

Answer: 87

Step-by-step explanation:

This will be solved using an arithmetic progression. The formula will be:

= a + (n - 1)d

where,

a = first term = 10

d = common difference = 7

n = 12

Therefore, 12 term will be:

= a + (n - 1)d

= 10 + (12 - 1) × 7

= 10 + (11 × 7)

= 10 + 77

= 87

Therefore, the number of stitches that are in the 12th row will be 87.
