A culture started with 2000 bacteria after 5 hours it grew to 2600
Jobisdone [24]
P(t) = P₀ e^(kt) 

<span>Where P₀ is the initial population, </span>
<span>P(t) is the population after "t" time. </span>
<span>t is your rate (can be hours, days, years, etc. in this case, hours) </span>
<span>k is the growth constant for this particular problem. </span>

<span>So using the information given, solve for k: </span>

<span>P₀ = 2000 </span>
<span>P(4) = 2600 </span>

<span>P(t) = P₀ e^(kt) </span>
<span>2600 = 2000e^(k * 4) </span>
<span>1.3 = e^(4k) </span>

<span>Natural log of both sides: </span>

<span>ln(1.3) = 4k </span>
<span>k = ln(1.3) / 4 </span>

<span>Now that we have a value for "k", use that, the same P₀, then solve for P(17): </span>

<span>P(t) = P₀ e^(kt) </span>
<span>P(17) = 2000 e^(17ln(1.3) / 4) </span>

<span>Using a calculator to get ln(1.3) then to simplify from there, we get: </span>

<span>P(17) ≈ 2000 e^(17 * 0.262364 / 4) </span>
<span>P(17) ≈ 2000 e^(4.460188 / 4) </span>
<span>P(17) ≈ 2000 e^(1.115047) </span>
<span>P(17) ≈ 2000 * 3.0497 </span>
<span>P(17) ≈ 6099.4 </span>

<span>Rounded to the nearest unit: </span>

<span>P(17) ≈ 6099 bacteria  hope i could help =)))</span>

What is the value of log5, 125?<br><br> 3<br> 5<br> 15<br> 25
Juliette [100K]

Answer:

3

Step-by-step explanation:

Using the rule of logarithms

log_{b} x = n ⇒ x = b^{n}

let log_{5} 125 = n , then

125 = 5^{n} , that is

5³ = 5^{n}

Since the bases on both sides are equal, both 5 then equate the exponents

n = 3
