At the beginning of an experiment, the number of bacteria in a colony was counted at time t=O. The number of bacteria in the col
yan [13]

Answer:

1092

Step-by-step explanation:

We have been given that the number of bacteria in the colony t minutes after the initial count modeled by the function B(t)=9(3)^t. We are asked to find the average rate of change in the number of bacteria over the first 6 minutes of the experiment.

We will use average rate of change formula to solve our given problem.

\text{Average rate of change}=\frac{f(b)-f(a)}{b-a}

Upon substituting our given values, we will get:

\text{Average rate of change}=\frac{b(6)-b(0)}{6-0}

\text{Average rate of change}=\frac{9(3)^6-9(3)^0}{6}

\text{Average rate of change}=\frac{9(729)-9(1)}{6}

\text{Average rate of change}=\frac{6561-9}{6}

\text{Average rate of change}=\frac{6552}{6}

\text{Average rate of change}=1092

Therefore, the average rate of change in the number of bacteria is 1092 bacteria per minute.

2/3 - 8/12 show all the work!
Karo-lina-s [1.5K]

So we multiply 2 by 12, and get 24.

Then we multiply 8 by 3, and get 24.

Next we give both terms new denominators -- 3 × 12 = 36.

So now our fractions look like this:

<span><span>24/36</span>−<span>24/36</span></span><span><span>Since our denominators match, we can subtract the numerators.24 − 24 = 0So the answer is:<span>0/36 z</span></span><span>ero divided by anything is just zero. So that's the final answer:
<span>0</span></span></span>
