Answer:
Exponential
Step-by-step explanation:
<em>Starter:</em>
According to the title:
"Every day, half a bacteria population dies."
Exponential: y = ab^x ( b > 0 , b ≠ 1)
So the answer is C.
<em>Calculations:</em>
An exponential model is of the form y = a • b^t.
If you start with population of 500 million bacteria
t = 0
so 500 million = a • b^0 = a
Since every day half the population dies then in 1 day population will be 250 million
so a = 500 million, y = 250 million and t = 1
250 million = 500 million • b^1
b = 0.5
Therefore your equation would be
y = 500 million (or whatever the pop) • 0.5^t
Where t = number of days
This could also be written in exponential form ( e = 2.73)

Answer:
A. 
is Repeating
B. 
is Terminating
C. 
is Repeating
Step-by-step explanation:
We know is Repeating because when it is in decimal form there is a line above the 6 in 0.6
We know is Terminating because when it is in decimal form there is no line above any of the numbers in 0.6
We know is Repeating because when it is in decimal form there is a line above 54 in 0.54.
Hope this helps.
