in a lab experiment, 3500 bacteria are placed in a petri dish. The conditions are such that the number of bacteria is able to double every 19 hours. How many bacteria would there be after 21 hours, to the nearest whole number?

Step-by-step explanation:

I wish I knew I need help as well cuz I have the exact same question on my hw

answer: solve 5\cdot 2^x=2405⋅2  

x

=2405, dot, 2, start superscript, x, end superscript, equals, 240.

solution

to solve for xxx, we must first isolate the exponential part. to do this, divide both sides by 555 as shown below. we do not multiply the 555 and the 222 as this goes against the order of operations!

\begin{aligned} 5\cdot 2^x& =240 2^x& =48 \\ \end{aligned}  

5⋅2  

x

2  

x

​    

=240

=48
