-2 would at the end equal zero
2 at the end would equal -480
so i would go with the x=-2
1 mike = 1760 yards
3 x 1760 = 5280
3 miles is larger
Hope this helps!
The value of x is x=1/10
This can also be written as:
X=0.1
X=10^-1
The function that represents the number of E.coli bacteria cells per 100 mL of water as t years elapses, and is missing in the question, is:

Answer:
Option A. 59%
Explanation:
The base, 1.123, represents the multiplicative constant rate of change of the function, so you just must substitute 1 for t in the power part of the function::
Then, the multiplicative rate of change is 1.590, which means that every year the number of E.coli bacteria cells per 100 mL of water increases by a factor of 1.590, and that is 1.59 - 1 = 0.590 or 59% increase.
You can calculate it also using two consecutive values for t. For instance, use t =1 and t = 1
