Answer:
about 5.9%
Step-by-step explanation:
We assume that the original amount of Pb-210 present at death decays at the given rate. The fraction (f) remaining is multiplied by 1/2 every 22 years, so can be modeled by ...
f = (1/2)^(t/22) . . . . . where t is in years after death
Then, for t=90, the remaining fraction is ...
f = (1/2)^(90/22) ≈ 0.05868 ≈ 5.9%
It will be 0.073. because the 73 is in the 1000 place
Answer:
a(11) = 4^10 = 1048576
Step-by-step explanation:
The first term of this geometric sequence, a(1), is 1, and the common ratio, r, is 4. Each new term is 4 times the previous term. Thus,
a(n) = 1*4^(n - 1), and
a(11) = 4^10 = 1048576
Answer:
Yes it is
