Answer:

   11g2h2 + h2 + 13

 ———————————

                h2      

Step-by-step explanation:

Step  1  :

            4

Simplify   ——

           h2

Equation at the end of step  1  :

               9              4

 ((((4•(g2))+————)+(7•(g2)))+——)+1

             (h2)            h2

Step  2  :

Equation at the end of step  2  :

               9         4

 ((((4•(g2))+————)+7g2)+——)+1

             (h2)       h2

Step  3  :

            9

Simplify   ——

           h2

Equation at the end of step  3  :

              9        4

 ((((4•(g2))+——)+7g2)+——)+1

             h2       h2

Step  4  :

Equation at the end of step  4  :

             9              4    

 (((22g2 +  ——) +  7g2) +  ——) +  1

            h2             h2    

Step  5  :

Rewriting the whole as an Equivalent Fraction :

5.1   Adding a fraction to a whole

Rewrite the whole as a fraction using  h2  as the denominator :

            22g2     22g2 • h2

    22g2 =  ————  =  —————————

             1          h2    

Equivalent fraction : The fraction thus generated looks different but has the same value as the whole

Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator

Adding fractions that have a common denominator :

5.2       Adding up the two equivalent fractions

Add the two equivalent fractions which now have a common denominator

Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

22g2 • h2 + 9     4g2h2 + 9

—————————————  =  —————————

     h2              h2    

Equation at the end of step  5  :

   (4g2h2 + 9)             4    

 ((——————————— +  7g2) +  ——) +  1

       h2                 h2    

Step  6  :

Rewriting the whole as an Equivalent Fraction :

6.1   Adding a whole to a fraction

Rewrite the whole as a fraction using  h2  as the denominator :

          7g2     7g2 • h2

   7g2 =  ———  =  ————————

           1         h2  

Adding fractions that have a common denominator :

6.2       Adding up the two equivalent fractions

(4g2h2+9) + 7g2 • h2      11g2h2 + 9

————————————————————  =  ——————————

         h2                  h2    

Equation at the end of step  6  :

  (11g2h2 + 9)     4    

 (———————————— +  ——) +  1

       h2         h2    

Step  7  :

Adding fractions which have a common denominator :

7.1       Adding fractions which have a common denominator

Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

(11g2h2+9) + 4     11g2h2 + 13

——————————————  =  ———————————

      h2               h2    

Equation at the end of step  7  :

 (11g2h2 + 13)    

 ————————————— +  1

      h2          

Step  8  :

Rewriting the whole as an Equivalent Fraction :

8.1   Adding a whole to a fraction

Rewrite the whole as a fraction using  h2  as the denominator :

        1     1 • h2

   1 =  —  =  ——————

        1       h2  

Adding fractions that have a common denominator :

8.2       Adding up the two equivalent fractions

(11g2h2+13) + h2     11g2h2 + h2 + 13

————————————————  =  ————————————————

       h2                   h2      

Trying to factor a multi variable polynomial :

8.3    Factoring    11g2h2 + h2 + 13

Try to factor this multi-variable trinomial using trial and error

Factorization fails

Final result :

 11g2h2 + h2 + 13

 ————————————————

        h2

Starting with x1 = 2, find the third approximation x3 to the root of the equation x3 − 2x − 2 = 0.
andrew11 [14]

Answer:

0.8989

Step-by-step explanation:

Using the Newton's Raphson approximation formula.

Xn+1 = Xn - f(Xn)/f'(Xn)

Given f(x) = x³-2x+2

f'(x) = 3x²-2

If the initial value X1 = 2

X2 = X1 - f(X1)/f'(X1)

X2 = 2 - f(2)/f'(2)

f(2) = 2³-2(2)+2

f(2) = 8-4+2

f(2) = 6

f'(2) = 3(2)²-2

f'(2) = 10

X2 = 2- 6/10

X2 = 14/10

X2 = 1.4

X3 = X2 - f(X2)/f'(X2)

X3 = 1.4 - f(1.4)/f'(1.4)

f(1.4) = 1.4³-2(1.4)+2

f(1.4) = 2.744-2.8+2

f(1.4) = 1.944

f'(1.4) = 3(1.4)²-2

f'(1.4) = 3.880

X3 = 1.4- 1.944/3.880

X3 = 1.4 - 0.5010

X3 = 0.8989

Hence the value of X3 is 0.8989

Find the values of x and y if l // m. <br> Show all work.
____ [38]

Answer:

x = 7, y = 24

Step-by-step explanation:

23x -16 + 8x - 21 = 180 because they are supplementary angles

31x - 37 = 180

31x = 217

x = 7

23(7)-16 = 7y - 23 because they are vertical angles

168 = 7y

y = 24
