When a certain over the counter drug enters the bloodstream, it gradually dilutes, decreasing exponentially. you take a 200 mg dose at 8: 00pm, and by 11: 00pm, there is only 75 mg remaining.
if the drug is only effective with at least 65 mg in the blood stream, about what time should you take another dose?
assume you don’t take another dose after 8: 00pm, how much would be left in your blood stream after 10 days?

1. minimum

2. 6400

3. eight

hope this !

what is the answer?

he has now walked a total of what?

if i know what this is maybe i can

step-by-step explanation:

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

=240

=48
