Answer:
Step-by-step explanation:
Decay is defined by the function as,
f(t) =
Here, r = rate of decay
t = duration of decay Or time (In years)
n = Number of times of decay in a year
Decay every 2 years over a period of t years,
f(t) =
=
Therefore, will be the answer.
Decay 2 times a year over a period of t years,
f(t) =
Therefore, will be the answer.
Decay once per year over a period of t years,
f(t) =
=
Therefore, will be the answer.
Answer:
Step-by-step explanation:
These are mostly calculator problems. The only trick is the last one. Your calculator will have either a y^x button or ^ button. They both do the same thing.
So for the last one, you must do it as
64 y/x (1÷6)= and you will get 2. Perhaps all of them should be done that way.
If your calculator uses ^ then you would do it
64^(1÷6)= which is the same thing.
