it means 3 and then "e" means is up of the 3so its 3↖-6
Answer: 41.5 min
Step-by-step explanation:
This problem can be solved with the Radioactive Half Life Formula:
(1)
Where:
is the final amount of the radioactive element
is the initial amount of the radioactive element
is the time elapsed
is the half life of the radioactive element
So, we need to substitute the given values and find from (1):
(2)
(3)
(4)
Applying natural logarithm in both sides:
(5)
(6)
Clearing :
This is the time elapsed
Answer:
a i think
Step-by-step explanation:
Answer:
Neither
Step-by-step explanation:
To be parallel the lines have to have the same slope. In this case the slopes are not the same.
To be perpendicular, the lines have to have negative reciprocal slopes.
For example, if one slope is 6, then its negative reciprocal i (- 1/6). We do not have this also.
So, the lines are no parallel and no perpendicular.
The answer is zero hope that helps
