Your firm needs a computerized machine tool lathe which costs $42,000 and requires $11,200 in maintenance for each year of its 3-year life. After three years, this machine will be replaced. The machine falls into the MACRS 3-year class life category, and neither bonus depreciation nor Section 179 expensing can be used. Assume a tax rate of 21 percent and a discount rate of 12 percent. If the lathe can be sold for $4,200 at the end of year 3, what is the after-tax salvage value? Note: Round your answer to 2 decimal places.

In humans there are three alleles for blood type, $I^A$, $I^B$ and $i$; which give rise to the A, B, AB and O blood types. Individuals that are homozygous recessive with a genotype $ii$ have type O blood. Native Americans are believed to have descended from a small population of people that migrated from Asia through Alaska. Scientists believe that this small group had reduced genetic diversity with regard to blood type, and Native Americans today have a much higher frequency of O alleles than that of the general population. This example demonstrates a phenomenon known as Founder effect. Mutation Bottleneck effect. Natural selection

The velocity of water, $v$ (m/s), discharged from a cylindrical tank through a long pipe can be computed as $\sqrt{2gH} v = \sqrt{2gH} \tanh(\frac{\sqrt{2gH}}{2L}t)$ where $g = 9.81 \text{ m/s}^2$, $H = \text{initial head (m)}$, $L = \text{pipe length (m)}$, and $t = \text{elapsed time (s)}$. a. Graphically determine the head needed to achieve $v = 5 \text{ m/s}$, in 2.5 s for 6 m-long pipe. b. Determine the head for $v = 4 - 7 \text{ m/s}$ (at 0.5 m/s increments) and times of 2 to 4 s (at 0.5 s increments) via the bisection method with stopping criteria of 0.1% estimated relative error. c. Perform the same series of solutions with the Regula Falsi method where you choose the same starting points and convergence tolerance. d. Which numerical method converged faster?
