Answer:
-3
Step-by-step explanation:
The general rule can be found by noticing patterns such as the numbers get smaller by 3 from the first term 3 towards the next 0 and towards next one -3
term 1: 3
term 2 : 3 -3 = 0
term 3 : 0 -3 = -3
The general rule of 3;0;-3 is subtract 3
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
Step-by-step explanation:
I think you mean that 10 cm³ of air are escaping every second.
and we start with a volume of 500 cm³.
V = 500 - 10t 0 <= t <= 50
because negative t (seconds) don't make any sense, and neither does a negative volume (for t > 50).
