The third one because 2(15+5)=2(20)=40
Answer:
44.36
Step-by-step explanation:
44.3551 ~ 44.36
Note: 2 decimal places is something like 9.55, 10.67 and etc. If your using 44.3551 to find out how to round off to two decimal places, focus on the 51 at the back of the number since that will be excluded from the answer.

Answer:
y=Ae^(1.25t)
Step-by-step explanation:
From the expression y=Ae^kt
After two days of the experiment, y = 49 million, t=2
After four days of the experiment, y= 600.25 million, t=4
A is the amount of bacteria present at time zero and t is the time after the experiment (in days)
At t=2 and y =49
49=Ae^2k…………….. (1)
At t=4 and y = 600.25
600.25=Ae^4k………… (2)
Divide equation (2) by equation (1)
600.25/49=(Ae^4k)/(Ae^2k )
12.25=e^2k
Take natural log of both sides
ln(12.25) =2k
2.505 =2k
k=1.25
The exponential equation that models this situation is y=Ae^(1.25t)
