Consider laminar steady boundary layer at a flat plate. Assume the velocity profile in the boundary layer as parabolic, u(y)=U(2 (y/δ)-(y/δ)^2).

1. Calculate the thickness of the boundary layer, δ(x), as a function of Reynold's number.

2. Calculate the shear stress at the surface, τ, as a function of Reynold's number.

a) Prove that an isolated point of set A is a boundary point of A (where A is a subset of real numbers).

b) Prove that a set is closed if and only if it contains all its boundary points

Describe the boundary lines for two- variable inequalities. Why are the boundary lines for two- variable inequalities with greater than and less represented by dotted lines? Provide examples.
First, define a boundary line and tell where it comes from. Then, describe what the boundary line can tell us about solutions to an inequality. You can also talk about how to know what part of a graph to shade. Finally , talk about the cases where we use each type of boundary line. ( solid and dotted/ dashed).
Real - life Relationship: If you have 100 $ available to buy party favors ( 3$ per bunch of balloons and 4 $ per bag of candy) than you can solve an inequality to find the possibilities . If x = # of bunches of balloons and y= number of bags of candy then we want to solve: 3x+ 4y<=100.
Some possible solutions are: no bunches of balloons and 25 bags of candy,20 bunches of balloons and 10 bags of candy. There are other possibilities!
Challenge: Imagine we have two boundary lines: one solid and one dashed. If they are not parallel is the point where they meet included in the solution? Why or why not?
If you are not sure, try an example, such as y < x + 1 and y < = 2x-4. Graph both boundary lines and find the point of intersection. Then , see if the coordinates satisfy both inequalities.

what I have to find. There are 2 data FUNDS in the file: Technology and Energy.

1) For each fund, compute using Excel: the Average, Median, Mode, the first percentile, the third percentile.

2) Graph the Box-Plot for each fund (called Box and Whisker in Excel).

3) For each fund, compute using Excel: the Range, Mean Absolute Deviation, the variance, the standard deviation and the coefficient of variation.

4) Using Excel, compute the Sharpe-Ratio for each fund using the risk free return of 3%. 5) Using Excel, compute the correlation between both funds.

(a) Use Excel, MegaStat, or MINITAB to fit three trends (linear, quadratic, exponential) to the time series. (A negative value should be indicated by a minus sign. Do not round the intermediate calculations. Round your final answers to 2 decimal places.)

(b) Use each of the three fitted trend equations to make numerical forecasts for the next 3 years. (Round the intermediate calculations to 2 decimal places and round your final answers to 1 decimal place.)

When performing calculations in the following problems, use the numbers in the table as-is. I.e., do NOT convert 8.5985 to 8.5985% (or 0.085985). Just use plain 8.5985.

1. What is the portfolio's M2 measure?

2. What is the Sharpe Ratio of the portfolio using the following equation: Sharpe Ratio = Rp − Rf / (σp)
