Answer:
Step-by-step explanation:
14 = 1000 
.014 = 
ln(.014) = k ln(e)
k = -4.268
~~~~~~~~~~~~~~~~~~
after 3 hrs
1000 
0.00274
~~~~~~~~~~~~~~~
4 = 1000 
.004 = 
ln(.004)/-4.268 = t
t = 1.29368 hrs
Hello, Jssoyg! I've solved the problem for you below. I hope it helps.
Slope equation is
. The two points are (0,1) and (4,2), so the equation becomes
. We now know that the slope is 1/4, so now let's write it in the
format. Plug in the m, x, and y values:
.
This becomes
which means b = 1.
Your answer is y = 1/4x + 1. Hope this was helpful. :D
