Question:
A radioactive substance decays exponentially with half-life l. Suppose the amount of the substance initially present (when t = 0) is Q0.
a. Show that the amount of the substance that remains after t years will be Q(t) = Q0e−(ln 2/λ)t.
b. Find a number k so that the amount in part (a) can be expressed as Q(t) = Q0(0.5)kt.
