use the approximate Half-Life formula for the casedescribed below.discuss whether the formula is valid for the casedescribed. poaching is causing a population of elephants to declineby 8% per year. (1) what is the half-life for the population? (2)there are 10,000 elephants today how many will remain in 40 years?(3) does the approximate Half-Life formula give a valid a proximastation in the case described. yes or no?
