Answer:
even I think
Step-by-step explanation:
<h3>A.</h3>
See below for a graph
<h3>B.</h3>
The inverse of a function appears on a graph as the reflection of the function across the line y=x. This is because the inverse relation is effectively the same relation with the variables x and y swapped. Here, the graphs of f(x) and g(x) are mirror images of each other across the line y=x, so we can see they are inverse functions.
The same technology allows us to graph y=f(g(x)) and y=g(f(x)). Both are graphs of y=x, as expected.
14 mph
Step-by-step explanation:
13.636364
is what you get by doing
100/15 then you get 6.6666......7
after that you multiply that by 3600 because thats how many seconds in that hour.
Then you get 24000 and transfer it to miles and get 13.636364 and you round it and get 14mph
On the way to the airport he drove with 45 mph in 3 h
the distance is 45mph*3h=135 miles
on the way back, he drove with 55 mph
55mph/?h=135 miles
h=135/55= 2.5
