Answer:
The correct option is C. The function 
is a stretch of an exponential decay function.
Step-by-step explanation:
The general form of an exponential function is
where, a is the initial value and b is the growth factor.
If b<1, then it represents a decay function and if b>1, then it represents a growth function.
Let k be a stretch and compression factor.
If k<1, then it represents vertical compression and if k>1, then it represents vertical stretch.
In third function
Therefore the function is a stretch of an exponential decay function.
Answer:
18/5 hours or 3 3/5 hours
Step-by-step explanation:
I assume the break is at 7/5 hours.
5 hours - 7/5 hours = 25/5 hours - 7/5 hours = 18/5 hours = 3 3/5 hours
It just wants you to simplify your expression. Does every single variable have a number in common?
