I only know one and i would say that it is the first one .

Answer:
x-intercept : (-0.1429,0)
y-intercept : (0,0.25
If the bacteria is tripling every 10 minutes, that means the "rate of increase" on that period is 200%, so if say the current amount is "c", 200% of "c" is just 2c, so c + 2c is 3c, a tripled amount.
N + 3 simply means we are adding 3 to the number before. An example of such of a pattern would look like this:
3, 6, 9, 12
4, 7, 10, 13
5, 8, 11, 14
Answer:
Mean is 18
Step-by-step explanation:
We would set up the proportion as X/9=36/X so after we cross multiply we get x^2=324. Then we find the square root of both sides to simplify. ... And the square root of 324 is 18. So the final answer is x=18 or the geometric mean is 18
