Answer:
5.1 days
Step-by-step explanation:
Given in the question,
initial amount of substance = 34 grams
k-value = 0.137
To find the half life of this substance we will use following formula
here N(0) is initial amount of substance
t is time in days
Plug values in the formula
1/2 = e^{-0.137t}
Take logarithm on both sides
ln(1/2) = ln( e^{-0.137t})
ln(1/2) = -0.137t
t = ln(1/2) / -0.137
t = 5.059
t ≈ 5.1 days (nearest to tenths)
X > 90 idk if thats what u mean or not
Answer:
Step-by-step explanation:
it is table 4, because it y has constant change for every input of x
which is 2
-4/-2=-8/-4=-16/-8=2
I'm doing that practice rn too tell me if you got the answer!
