    Answer: half life = 1.98 seconds

    Step-by-step explanation:

    Given that the amount of sodium-24 in the patient's body in milligrams after t hours is given by

    S (t) = 5e-0.35t.

    From the equation above, decay constant K = 0.35

    Half life = ln2/K

    Half life = ln2 / 0.35

    Half life = 1.98 seconds
