It would be an obtuse angle :)
Exponential decay is a very common process especially when we are talking about radioactive materials. So, there is already a common formula for this type of behavior which is written below:
A = Pe^-rt
where
A is the amount left after time t
P is the initial amount at t=0
r is the rate
Substituting the values,
A = (780 g)(e^-0.163*16)
A = 57.5 g
Answer:
= 2x
Step-by-step explanation:
Answer:
The answer should be: r ≈ 8.21
n+29 is that what you mean
