In Example 2 the decay constant for isotope RA₁ was 10/sec, which expresses itself in the exponent of the rate term 50e^-10t kg/sec. When the decay constant for RA₂ is k = 2/sec, we see that in formula (14) for y the term (185/4)e^-2t eventually dominates (has greater magnitude for t large).

(a) Redo Example 2 taking k = 20/sec. Now which term in the solution eventually dominates?

(b) Redo Example 2 taking k = 10/sec.
