The half-life of (carbon-14) is 5730 years. that is, it takes this many years for half of a sample of to decay. if the decay of is modeled by x' = -rx, where x is the amount of , find the decay constant r. ( r = 0.000121 yr⁻¹). in an artifact the percentage of the original remaining at the present day was measured to be 20 %. how old is the artifact?
