Well when there is a minus sign and a parenthesis and another minus sign after it it makes a plus sign so all you have to do is 2+5 and the answer is 7
Yes, they are proportional, as when you double 2.5, you get 5, and when you double 3.5, you get 7
Hope this helps :)

Answer:
Explanation:
The function that represents the number of E.coli bacteria cells per 100 mL of water as the time t years elapses is:
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.
