Answer:
9.4 days
Step-by-step explanation:
Filling in the given numbers, we can solve for t:
0.18 = 1·(1/2)^(t/3.8)
log(0.18) = (t/3.8)log(1/2)
t = 3.8·log(0.18)/log(0.50) ≈ 9.4 . . . . days
The best estimate of the age of the sample is 9.4 days.
we can simply just draw them, notice it is a vertical line
Check the picture below.
The triangles are similar because of the SAS postulate. The sides are proportional and angle T is equal in both.
