Question

An investment of $1,890,000 produces a perpetual stream of cash flows. Next year, the cash inflow will be $94,500, and this will grow at 4% per year forever. What is (are) the IRR/ (IRR

The half-life of 222Rn is 3.83 days. Convert the half-life to seconds. Calculate the decay constant for this isotope. s?1 Convert 0.650 mu Ci to the SI unit the becquerel. Bq Find the number of 222Rn nuclei necessary to produce a sample with an activity of 0.650 mu Ci. 222Rn nuclei Suppose the activity of a certain 222Rn sample is 6.60 mCi at a given time. Find the number of half-lives the sample goes through in 40.2 d and the activity at the end of that period.

Explanation / Answer

let IRR = r


1890000 = 94500/(r-0.04)


r=0.04+0.05=0.09=9%
