Use the definition of absolute value.
The absolute value is always non-negative. So if is already non-negative,
is unchanged. But if
is negative, then
because multiplying
by -1 makes it positive.
Now, if , then by the definition of absolute value,
Answer:
$39,851.25
Step-by-step explanation:
If the sales increase at a rate of 9% per year, this means it will be 109% of the previous year's value since 100% + 9% = 109%
109% in decimal form = 109/100 = 1.09
Therefore, the exponential function is:
, where
is the number of years
So when ,
After 8 years, annual sales = $39,851.25
