Answer:
angle x is 86
angle y is 38
Step-by-step explanation:
Answer:
We can use the sample about 42 days.
Step-by-step explanation:
Decay Equation:
Integrating both sides
When t=0, N= = initial amount
.......(1)
.........(2)
Logarithm:
130 days is the half-life of the given radioactive element.
For half life,
, days.
we plug all values in equation (1)
We need to find the time when the sample remains 80% of its original.
We can use the sample about 42 days.
