Question

Involve exponential growth or decay.

If you have 50 grams of carbon-14 today, how much will be left in 100 years? Note that the half-life of carbon-14 is 5730 years (ie. y(5730) = 25).

Answer 1

Answer 2

y = A*(1/2)^(x/H)

A = original amount
H = halflife

y = 50*(1/2)^(x/5730)

y = 50*(1/2)^(100/5730)

y = ??

Answer 3

49.39

Answer 4

49.39880 which turns into 49.40 if you're rounding to 2 decimal places

Answer 5

okay
