Answer:
3.48 hours
Step-by-step explanation:
The equation is:

Where
M(t) is the amount of medication remaining in mg
t is the time it takes, in hours
The questions asks HOW LONG it will take to make the remaining medication to 1 milligrams (1 mg)??
We have to substitute M(t) with "1" and find the corresponding value of "t". We will use natural log to solve this. Shown below:

<u>Note: </u> Ln(e) = 1
This means, the amount of time it will take is about 3.48 hours
<u>6
</u>13.20
Divide by 6
<u>1
</u>2.2
For this problem, you would have to use a system of equations. Hope this helps!
Step-by-step explanation:
angle B=6x+4
6x=4
x=4/6
x=0.6
