9. A plumber charges $25 to come to your house. He also charges $60 for each hour that he works. The
1 answer:
Answer:
The formula would be (where "h" is the number of hours and C is the total amount of money given to the plumber). And if we use this formula we will know that In this case, the plumber was working for 2 hours
Step-by-step explanation:
From the question itself, we know if we let "h" represent the numbers of hours the plumber works and "C" represents the total amount of money paid to the plumber, then we can write the following equation...
C = 60h + 25
From here we can rearange the formula and get the following...

Answer:
The inner function is and the outer function is
.
The derivative of the function is .
Step-by-step explanation:
A composite function can be written as , where
and
are basic functions.
For the function .
The inner function is the part we evaluate first. Frequently, we can identify the correct expression because it will appear within a grouping symbol one or more times in our composed function.
Here, we have inside parentheses. So
is the inner function and the outer function is
.
The chain rule says:
It tells us how to differentiate composite functions.
The function is the composition,
, of
outside function:
inside function:
The derivative of this is computed as
The derivative of the function is .
