Situation: Find the substance's half-life, in days.
Round your answer to the nearest tenth.
A 22 gram sample of a substance that's
used to sterilize surgical instruments has
a k-value of 0.1354.
Enter the correct answer.
N= Noekt
DONE
No = initial mass (at time t = 0)
OOO
OO
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

idk

step-by-step explanation:

we have three similar triangles, because each has a right angle and shares an angle.   let's write the angles in order: opposite to short leg, long leg, hypotenuse.

cab similar to bad similar to cbd

or as ratios,

ca: ab: cb = ba: ad: bd = cb: bd: cd

we also know

ac = ad + cd

(ad+cd): ab: cb = ba: ad: bd = cb: bd: cd

(ad+cd)/cb=cb/cd

we have cb=6, ad=5 and seek x=cd.

we reject the negative root and conclude x=4

answer: 4
