dsp73

<em>Answer:</em>

<em>Can be found below</em>

<em>Step-by-step explanation:</em>

<em>Part A:</em>

<em>So we know that the bacteria doubles every (30) minutes.</em>

<em>2000 times 2 equals 4000 (30 minutes)</em>

<em>4000 times 2 equals 8000 (1 hour)</em>

<em>Answer for Part A:</em>

<em>8000 bacteria</em>

<em>Part B:</em>

<em>Now we do this function 2000(2)^14 (30 minutes long)</em>

<em>Answer to Part B: </em>

<em>I believe the answer is 32,768,000 (Please correct me if I'm wrong) </em>

<em>Hope I could help!! Have a great day/night!</em>

Between x=2 and x=3, which function has a greater average rate of change than f(x)=2^x has?

maxonik [38]

Answer: f(3)

Step-by-step explanation:

First find the formula for the rate of change by taking the derivative of 2^x. Let f(x) equal some hypothetical y-value, then take the natural log of both sides.

$y=2^x\\\ln(y)=x \ln(2)$

Implicitly differentiate the left side and take the derivative of the right side

$\frac{y'}{y} =\ln(2)$

Multiply both sides by 'y' which was defined as 2^x

$y'=\ln(2)*2^x$

Plug in x = 2 and x = 3 to see which slope is larger

$y'=\ln(2)*2^2=4\ln(2)\\y'=\ln(2)*2^3=8\ln(2)$
