138 because 92/4 equals 23 which is the miles per gallon, then you multiply that by 6<span />
Solution:
As we given that
then using this conversion factor we can write 
and further it can be written as

Hence the required conversion factor is 2.54 cm/1 inch as we can see from the above calculation.
Answer: D
Step-by-step explanation:
The graph is narrower, so the coefficient of
has an absolute value more than 1.
Also, because g(x) opens down, the coefficient of
is negative.
This leaves D as the answer.
