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.

Find the slope of the line: x/-1 + y/6 = 1

pychu [463]

The slope-intercept form: y = mx + b

m-the slope

$\dfrac{x}{-1}+\dfrac{y}{6}=1\\\\-x+\dfrac{y}{6}=1\ \ \ \ |add\ x\ to\ both\ sides\\\\\dfrac{y}{6}=x+1\ \ \ \ |multiply\ both\ sides\ by\ 6\\\\y=6x+6\\\\\\Answer:\boxed{The\ slope\ m=6}$
