Answer: 19200 years
Step-by-step explanation:
The fossil in the above question has aged for 3.3 half lives. Since the half life of a fossil is given as 5730 years, the age of the fossil will be given as:
= 5730 years × 3.3333333
= 19200 years
Therefore, the age of the fossil is 19200 years.

Answer:
64
Step-by-step explanation:
Given :
h α 1 / sqrtk
h = k/sqrt(d)
Obtain the value of k, when. d = 4 and h = 20
20 = k / sqrt(4)
20 = k / 2
20 * 2 = k
k = 40
Therefore, the value of d when h = 5
h = k/sqrt(d)
5 = 40 / sqrt(d)
Square both sides
25 = 1600/d
25d = 1600
d = 1600 / 25
d = 64
d = 64
