The partial fraction decomposition of 9 x 11 6 x 2 23 x 21 can be written in the form of f ( x ) 2 x 3 g ( x ) 3 x 7 , where

Answers

Answer:

[tex]f(x) = -1[/tex]

[tex]g(x) =6[/tex]

[tex]\frac{-1}{2x + 3} + \frac{6}{3x + 7}[/tex]

Step-by-step explanation:

The question is unreadable, however the real polynomial is:

The polynomial fraction is:

[tex]P = \frac{9x + 11}{6x^2 + 23x + 21}[/tex]

And the decomposition is:

[tex]\frac{f(x)}{2x + 3} + \frac{g(x)}{3x + 7}[/tex]

The solution is as follows:

[tex]P = \frac{f(x)}{2x + 3} + \frac{g(x)}{3x + 7}[/tex]

Substitute the expression for P

[tex]\frac{9x + 11}{6x^2 + 23x + 21} = \frac{f(x)}{2x + 3} + \frac{g(x)}{3x + 7}[/tex]

Expand the numerator of the polynomial

[tex]\frac{9x + 11}{(2x + 3)(3x + 7)} = \frac{f(x)}{2x + 3} + \frac{g(x)}{3x + 7}[/tex]

Take LCM

[tex]\frac{9x + 11}{(2x + 3)(3x + 7)} = \frac{f(x)*(3x + 7) + g(x)*(2x + 3)}{(2x + 3)(x + 7)}[/tex]

Cancel out both denominators

[tex]9x + 11} = f(x)*(3x + 7) + g(x)*(2x + 3)[/tex]

Represent f(x) as A and g(x) as B

[tex]9x + 11} = A*(3x + 7) + B*(2x + 3)[/tex]

Open bracket

[tex]9x + 11} = 3Ax + 7A + 2Bx + 3B[/tex]

[tex]9x + 11} = 3Ax + 2Bx+ 7A + 3B[/tex]

[tex]9x + 11} = (3A + 2B)x+ 7A + 3B[/tex]

By comparison:

[tex]3A + 2B = 9[/tex] ---- (1)

[tex]7A + 3B =11[/tex] ---- (2)

Make B the subject in (1)

[tex]B = \frac{9 - 3A}{2}[/tex]

Substitute [tex]B = \frac{9 - 3A}{2}[/tex] in (2)

[tex]7A + 3(\frac{9 - 3A}{2}) = 11[/tex]

Multiply through by 2

[tex]2*7A +2* 3(\frac{9 - 3A}{2}) = 11*2[/tex]

[tex]14A + 3(9 - 3A) = 22[/tex]

[tex]14A + 27 - 9A = 22[/tex]

Collect Like Terms

[tex]14A - 9A = 22-27[/tex]

[tex]5A = -5[/tex]

[tex]A = \frac{-5}{5}[/tex]

[tex]A = -1[/tex]

Recall that:

[tex]B = \frac{9 - 3A}{2}[/tex]

[tex]B = \frac{9 - 3 * -1}{2}[/tex]

[tex]B = \frac{9 + 3}{2}[/tex]

[tex]B = \frac{12}{2}[/tex]

[tex]B = 6[/tex]

A = -1 and B = 6

[tex]3A + 2B = 9[/tex] ---- (1)

[tex]7A + 3B =11[/tex] ---- (2)

So:

[tex]f(x) = A[/tex]

[tex]f(x) = -1[/tex]

[tex]g(x) =B[/tex]

[tex]g(x) =6[/tex]

And the decomposition is:

[tex]\frac{-1}{2x + 3} + \frac{6}{3x + 7}[/tex]

Write an exponential function represented by the table

Y | -50 | -10 | -2 | -0.4 |

Answers

Answer:

50-10-2-4=34 RESPONS Y

Answer:

y = -50(1/5)^x

Step-by-step explanation:

Exponential function:

y = ab^x

As per the table we have:

The initial value is -50 at x= 0Common ratio is 1/5

Considering the above, a = -50, b = 1/5

The function is:

y = -50(1/5)^x

y
g(x)
X
Vertex:

Answers

Answer:

g(x) = (x - 4)^2 - 5, and the vertex is (4, -5)

Step-by-step explanation:

Please, use " ^ " to indicate exponentiation:  g(x) = (x - 4)^2 – 5.  Comparing this to y = a(x - h)^2 + k, we see that h must be 4 and k must be -5.  Thus, the vertex is (4, -5).

Make a table showing several x-values and the corresponding y-values:

x       g(x) = (x - 4)^2 - 5                     (x, y)

0                    (-4)^2 - 5 = 11               (0, 11)

4                (4 - 4)^2 - 5 = -5               (4, -5)
