Prime factorization of 1866 = 2, 3, 311
The formula for half-life is given by:
N(t)=Ne^(-λt)
or
N(t)=N(1/2)^(t/τ)
where:
t=time
N=initial amount
N(t)=final amount
τ=half-life
thus the time taken for the drug to decay will be:
10=80(1/2)^(t/8)
1/8=(1/2)^(t/8)
introducing natural logs;
ln (1/8)=(t/8)ln (1/2)
thus;
[ln 1/8]/[ln 1/2]=t/8
3=t/8
t=3*8
t=24 hours
the answer is 24 hours
Joan: 12 years old
Amber: 22 years old
If Amber is 2 years less than twice the age of Joan that means that Joan's age (12) times 2 (=24), minus 2 (=22) gives u Amber's age. Also when the two ages are added 12+22 they equal 34
Hope this helps! :)
