When interest is compounded continuously, the amount of money increases at a rate proportional to the amount S present at time $t$, that is, $dS/dt = rS$, where $r$ is the annual rate of interest. (a) Find the amount of money accrued at the end of 5 years when $8000 is deposited in a savings account drawing $5\frac{3}{4}$% annual interest compounded continuously. (Round your answer to the nearest cent.) $ (b) In how many years will the initial sum deposited have doubled? (Round your answer to the nearest year.) 12 years (c) Use a calculator to compare the amount obtained in part (a) with the amount $S = 8000\left(1 + \frac{1}{4}(0.0575)\right)^{5(4)}$ that is accrued when interest is compounded quarterly. (Round your answer to the nearest cent.) $ = $

1. Stock solutions of 0.00200 M Fe(NO$_3$)$_3$, 0.00250 M NaSCN and distilled water are mixed according to the following table. Copy the table into your laboratory notebook. The initial concentrations of the ions will be determined taking into account the dilution that occurs when the solutions are mixed. Assume the volumes are additive. Calculate these concentrations, [Fe$^{3+}$]$_{initial}$ and [SCN$^-$]$_{initial}$ that result from dilution if NO reaction takes place. SHOW your work for solution #1.

Consider an M/G/1 queue in which bulk arrivals occur at rate \lambda and with a probability $g_r$ that $r$ customers arrive together at an arrival instant. (a) Show that the z-transform of the number of customers arriving in an interval of length $t$ is $e^{-\lambda t[1 - G(z)]}$ where $G(z) = \sum g_r z^r$. (b) Show that the z-transform of the random variables $v_n$, the number of arrivals during the service of a customer, is $B^\prime[\lambda - \lambda G(z)]$.
