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,
Let's r the ration
We suppose x ≠0
x=r*(x-2)==>r=x/(x-2)
x+3=r*x==> (x+3)/x=x/(x-2)==>(x+3)(x-2)=x²
==>x²+3x-2x-6=x² ==>x-6=0==>x=6
x-2=6-4=4
x=6
x+3=6+3=9
6=4*3/2
9=6*3/2
Ration 3/2
First term: 4
Answer:
can't understand the question.
