\mathfrak{\huge{\orange{\underline{\underline{AnSwEr:-}}}}}

for f(0) ,here substitute x = 0

so we get as ,

==> f(0) = -8(2)^0 -12

If U-235 has a half-life of 713 million years and the age of the sample is 2.631 billion years old then how many half-lifes has
lutik1710 [3]
<span>As the age of the U-235 sample is 2.631 billion years, and the half-life of U-235 is 713 million years, the sample has undergone 2.361 X 1,000,000,000 / 713 X 1,000,000 = 3.69 half lives. In each half-life the sample reduces to half its original weight according to the radioactive Half-Life Formula: ln (Nt /N0) = -kt, where N0 = mass of the original weight of radioactive material, Nt = mass of radioactive material at time t, k = decay constant and t = time interval . We have to put Nt/N0 = 1/2 for time interval = half-life.</span>
