Find ( f o g) (x) when f (x) = x^2+6x+5 and g(x)=1/x+1
olchik [2.2K]

Answer:

(f\circ g)(x)=\frac{1}{x^{2}}+\frac{8}{x}+12

Step-by-step explanation:

Given that f (x) = x^{2}+6x+5 and g(x)=\frac{1}{x}+1 are the functions.

To find (f\circ g)(x) with the given two functions. ie., to find the composite function of f(x) and g(x) which is denoted by (f\circ g)(x)

(f\circ g)(x)=f(g(x))

                 =f(\frac{1}{x}+1)

                  =({\frac{1}{x}+1})^{2}+6\times ({\frac{1}{x}+1})+5

                   =\frac{1}{x^{2}}+\frac{2}{x}+1+\frac{6}{x}+6+5

                     =\frac{1}{x^{2}}+\frac{8}{x}+12

Therefore (f\circ g)(x)=\frac{1}{x^{2}}+\frac{8}{x}+12

Therefore the composite function of f(x) and g(x) is  (f\circ g)(x)=\frac{1}{x^{2}}+\frac{8}{x}+12

14 a and b please !!!

\frac{2}{3x - 2c} + ( - ( \frac{3}{2x - 3c} )) = \frac{7}{2c}

\frac{2}{3x - 2c} - \frac{3}{3x - 2c} = \frac{7}{2c}

\frac{2 - 3}{3x - 2c} = \frac{7}{2c}

\frac{ - 1}{3x - 2c} = \frac{7}{2c}

Next, cross-multiply.

- 2c = 21x - 14c

12c = 21x

x = \frac{7}{4} c= 1 \frac{3}{4} c

The integers between the interval of [2,7] without considering the inequality is [3, 4, 5, 6]

<h3>What is an integer?</h3>

An integer is a whole number that can either have a positive sign or a negative sign.

NOTE THAT:

  • the inequality is missing from the information given.

Therefore, the integers between the interval of [2,7] without considering the inequality is [3, 4, 5, 6].

Find the value of x. Show your work.
yarga [219]

Answer:

x = 11

Step-by-step explanation:

∠BCE + ∠ECF = 180°

∴(10x + 15)° + 5x° = 180°

(15x + 15)° = 180°

15x = 180° - 15°

15x = 165°

x = 165°/15°

x = 11°
