Answer:
25.9 years
Step-by-step explanation:
The half life of an isotope is related to the actual amounts by the equation:
N = Ni*(1/2)^(t/HL)
where N and Ni are the final and initial (Ni) amounts, t is the time (in years for this problem) and HL is the half-life, in years.
In this problem, we can write:
100 = 360*(1/2)^(x/14)
I'll reduce this to:
1 = 3.6*(1/2)^(x/14)
This can be solved by taking the log of both sides.
x = 25.87 or 25.9 years
Answer:
21 = 21
Step-by-step explanation:
5x + 1 = 21
-1 -1
5x = 20
__ __
5 5
x = 4
5x + 1 = 21 First substitute x for 4
5(4) + 1 = 21 Then continue to solve the problem to get the proof
20 + 1 = 21
21 = 21
The value of 5 is 50 in 3,156
