Please help me have been trying to solve this problem for a while and its been very frustrating.
Krypton91 is a radioactive substance that decays very quickly. The function Q(t)=Qoe^kt models the radioactive decay of krypton91. Q represents the quantity remaining after t seconds, and the decay constant, k, is approximately 0.07. How long will it take a quantity of krypton91 to decay to 10% of its original amount? Round your answer to the nearest second.
