7978 years
Step-by-step explanation:
A = A02^(-t/hl)
where hl = half-life.
Dividing both sides by A0 and taking the logarithm, we get
ln(A/A0) = -(t/hl)ln2
or solving for t,
t= -(hl)ln(A/A0)/ln2
note that A/A0 = 0.38
t = -(5715 yrs)[ln(0.38)/ln2]
= 7978 years

Answer:(-6,-2)
Step-by-step explanation:
If you put the -6 in the x and than the -2 in the y the x it would be (-6+6)=0 and times that one more time it gives u 0 and than 2•0=0 so 0-2=-2 hopefully I helped
