I am guessing that the correct form of equation
is:
f(x)
= 16,800(0.9)^x
where
x is the exponent of (0.9)
Since
we are looking for the original population and x stand sfor the number of years,
therefore x=0
substituting:
f(x) = 16,800(0.9)^0
Since (0.9)^0 would just be equal to 1. Therefore
the original population is
16,800.
Answer: B. 16,800
Answer is -23
Add 4 from both sides
Subtract 5 from both sides
Then divide 7
42m +12
Step-by-step explanation:
6(7m+2)
Distribute
6*7m +6*2
42m +12
The lower quartile is 60. Quartiles are the numbers in the middle of the median and lowest/highest number.
