Situation:
a 14 gram sample of a substance that's
used to sterilize surgical instruments has
a k-value of 0.1481.
n= noekt
no = initial mass (at time t = 0)
n = mass at time t
k = a positive constant that depends on
the substance itself and on the units
used to measure time
t = time, in days

find the half-life, in days. round your answer to the nearest tenth

easy math just plug in a and b

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

2  

x

​    

=240

=48
