Situation: A researcher in North America discovers a fossile that contains 38% of its original amount of C-14. N = Noe No = inital amount of C-14 (at time t = 0) N = amount of C-14 at time t k = 0.0001 t = time, in years. Find the age of the fissile to the nearest year.​

9514 1404 393

  9676 years

Step-by-step explanation:

Apparently, you have ...

  0.38 = e^(-0.0001t)

  ln(0.38) = -0.0001t . . . . . . . take the natural log; next, multiply by -10,000

  t = -10000ln(0.38) ≈ 9676 . . . . years

the highest percentage for deaths in construction from highest to lowest is as follows: falls, struck by objects, electrocution, and caught-in/between. these four are collectively known as fatal four.

in the case of falls, the type that is responsible for the overall highest death in the category is falls from roofs.
