When time is measured in days, the decay constant for a particular radioactive isotope is 0.14. Determine the time required for a confined sample of the isotope to fall to 40% of its original value. The time required for a confined sample of the isotope to fall to 40% of its original value is about days. (Do not round until the final answer. Then round to the nearest hundredth as needed.)
