The domain of [tex]b\,\circ \,a\,(x)[/tex] is [tex][1, +\infty)[/tex].

How to apply composition between functions

The composition of two functions consists in replacing the variable of the former function ([tex]b(x)[/tex]) by the latter function ([tex]a(x)[/tex]). If we know that [tex]b(x) = \sqrt{x-4}[/tex] and [tex]a(x) = 3\cdot x +1[/tex], then the composite function:

[tex]b\,\circ\,a \,(x) = \sqrt{(3\cdot x+1)-4}[/tex]

[tex]b\,\circ\,a\,(x) = \sqrt{3\cdot x-3}[/tex]   (1)

Since the composite function is a square root function, then the domain fulfill the following inequation:

[tex]3\cdot x -3 \ge 0[/tex]

[tex]x \ge 1[/tex]

Hence, the domain of [tex]b\,\circ \,a\,(x)[/tex] is [tex][1, +\infty)[/tex]. [tex]\blacksquare[/tex]

The list shows the numbers of each type of pie baked at a bakery today.
• 13 apple
• 4 pecan
• 3 pumpkin
What percentage of the pies baked today were NOT apple?

Answers

35%, because the apple pies account for 65% of the pies made

The percentage of pies baked that were not apple was 33.33 %

What is Percentage?

A percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, %

Given data ,

The number of apple pies baked at the bakery = 13

The number of pecan pies baked at the bakery = 4

The number of pumpkin pies baked at the bakery = 3

So ,

Total number of pies baked at the bakery =
Number of apple pies baked at the bakery + Number of pecan pies baked at the bakery + Number of pumpkin pies baked at the bakery

Total number of pies baked at the bakery = 13 + 4 + 3

                                                                      = 21

Now ,

The number of pies that were not apple = Number of pumpkin pies baked at the bakery + Number of pecan pies baked at the bakery

The number of pies that were not apple = 4 + 3

                                                                   = 7

And ,

The percentage of pies that were not apple =

( The number of pies that were not apple / Total number of pies baked at the bakery ) x 100 %

The percentage of pies that were not apple = ( 7 / 21 ) x 100 %

                                                                         = ( 1 / 3 ) x 100 %

                                                                         = 33.33 %

Hence , the percentage of pies that were not apple is 33.33 %

Answers

Answer:

c = 15

Step-by-step explanation:

The angles are4 a linear pair and are supplementary, so the sum of their measures is 180 deg.

7c - 7 + 6c - 8 = 180

13c - 15 = 180

13c = 195

c = 15

The answer should be 15.

Explanation:
The line equates to 180, so you would put both equations (7c-7 , 6c-8) together and equal it to 180°.
So, it would come out looking like this:
7c-7+6c-8=180.

You’d add 7c and 6c to get 13c, and then subtract -8 from -7 (-7-8) to get -15.
The equation would now look like this.
13c-15= 180.

You’d add 15 to 180 to get 195. Then, you’d divide 195 by 13 to get 15, which would mean c=15.
