P = 300e
, at what time will P=600?
|600||= 300e 2t|
|2||= e 2t|
A strain of bacteria multiply in such a fashion that they double in number every 4
Find an expression that describes this kind of growth.
|B(t) = B 0 e kt|
|B(t)||= B 0 e .173t|
Problem : Find a function that meets the following:
|e 0.693t = 0.693 e 0.693t|
The half-life of a substance is the time that it takes for the mass of that substance to decay
to 50% of its original value. If a certain substance has a half-life of 30 minutes, what is
an equation that describes its decay?
|C(t) = C 0 e kt|
|C 0||= C 0 e k(30)|
|= e 30k|
|C(t)||= C 0 e -0.0231t|
After 40 minutes, only 34% of a radioactive compound is remaining. What is the
expression describing its decay?
|C(t)||= C 0 e kt|
|.34C 0||= C 0 e k(40)|
|.34||= e 40k|
|C(t)||= C 0 e -0.027t|
