Ok
A=P(1/2)^(t/h)
A=amount final
P=initial amount
t=time elapsed
h=time of half life
so
given h=13
and initial =48g
and final is 12g
12=48(1/2)^(t/13)
divide both sides by 48
1/4=(1/2)^(t/13)
what a coincidence
(1/2)^2=(1/2)^(t/13)
so
2=t/13
26=t
26 hours have passed

Hello TheSection
Step-by-step explanation:
I see your stalking me right now. GIVE ME BACK BRAINLIEST RIGHT NOW TheSection THAT WAS MY 1st EVER AND YOU STOLE IT
Slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept.
The first step is to find the slope using the provided coordinates (-2, 6) and (2, 14). We can do that using the y1 - y2 / x1 - x2, like so:
6 - 14 / -2 - 2
-8 / -4
2
The slope is two, so we immediately know the answer is either A or B.
Now, plot the two points on graphing paper and determine where the line intersects the y-axis to find the y-intercept...
My graph shows the line intersecting the y-axis at 10, therefore the correct answer is:
y = 2x + 10
