Answer:

58 inches

Step-by-step explanation:

Perimeter means the sum of length of all sides of a figure.

So, the perimeter of this triangle would also be the sum of the length of its sides.

It has 3 sides.

19 in, 16 in and 23 in.

So, its perimeter equals 19 + 16+ 23

which equals 58 inches!

So, the perimeter would be 58 inches.!

Find (fog)(2) and (f+g)(2) when f(x) =1/x and g(x) =4x+9

Dahasolnce [82]

$( f o g)(2) = \frac{1}{17}$

$(f + g)(2) = \frac{35}{2}$

Solution:

Given that:

$f(x) = \frac{1}{x}\\\\g(x) = 4x + 9$

To find: (fog)(2) and (f + g)(2)

By composite function,

( f o g)(x) = f (g(x))

Substitute g(x) = 4x + 9 in above formula,

( f o g)(x) = f(4x + 9)

To find (fog)(2) substitute x = 2 in above formula

( f o g)(2) = f(4(2) + 9)

( f o g)(2) = f(8 + 9) = f(17)

We know that $f(x) = \frac{1}{x}$

$( f o g)(2) = f(17) = \frac{1}{17}$

$( f o g)(2) = \frac{1}{17}$

To find (f + g)(2)

We know that,

(f + g)(x) = f (x) + g(x)

Therefore,

(f + g)(2) = f(2) + g(2)

Substitute x = 2 in f(x) and g(x)

$(f + g)(2) = \frac{1}{2} + (4(2) + 9)\\\\(f + g)(2) = \frac{1}{2} + 17 = \frac{1+34}{2} = \frac{35}{2}$

$(f + g)(2) = \frac{35}{2}$
