Step-by-step explanation:
Since, the final quantity of an element which has half life of n periods,
Where,
P = initial quantity,
t = total number of periods,
Here, A = 1 gram, t = 1000 years, n = 5715 years,
By substituting the values,
( using calculator )
Hence, the initial quantity would be 1.1289 grams ( approx )

Answer:
20/29
Step-by-step explanation:
sin θ = 21/29
Use Pythagorean identity:
sin² θ + cos² θ = 1
(21/29)² + cos² θ = 1
441/841 + cos² θ = 1
cos² θ = 400/841
cos θ = ±20/29
Since 0° < θ < 90°, cos θ > 0. So cos θ = 20/29.
