High skilled immigrants use the H-1B visa to work in the United States. Prior to 2004, they allowed over 120000 visas to be issued each year. After 2004, they reduced the quota to 65000 immigrants per year. Discuss the implications that this change would have based on your knowledge of economic theory on a. native workers in the USA b. firm owners in the USA c. remaining workers in the destination countries d. firm owners on destination countries You may use graphical analysis if it helps illustrate your points.

Suzanne opens an account at a local bank on January 1, 2004 with a deposit of 4000 dollars. On October 1, 2004 she withdraws 1430 dollars. On April 1, 2005 she withdraws 850 dollars. And on April 1, 2007 she deposits 2090 dollars. Find the total present value of these transactions on July 1, 2006, if the account earns interest at a nominal rate of 7.6 percent convertible quarterly.

The solutions I've found on the website have not taken into account the future deposit and are incorrect, any suggestions?

Write the soln using separation of variables , in the form of fourir series:

Utt=Uxx

boundary: U(t,0)=0=U(t,pi)

initial :

initial: U(0,x)=1 and Ut(0,x)=0

Consider a plane wall with uniform thermal energy generation per unit volume of qdot. Starting with the steady-state heat equation, obtain a general expression for the temperature distribution (Since no boundary conditions are provided, there will be unknown constants in the resulting equation).

In a slowly cooled hypereutectoid iron-carbon steel,
the pearlite colonies are normally separated from each
other by a more or less continuous boundary layer of
cementite. Explain how this microstructure develops. Use
simple sketches to illustrate your answer

Solve the following boundary value problem by Laplace Transform. (If you solve with another
method you will NOT get credit. There is nothing wrong about the conditions.)
d2y
dt2 + y = cos(2t); y0(0) = 0; y0(

Imagine an octagon(8 vertices) with all its diagonals. Is it possible to draw this without lifting your pen (and no backtracking). If we attach a triangle for each boundary edges of the Octagon, can you draw this without lifting your pen? Explain

Let ?be the solid region bounded by the surfaces ?=10−?2−?2and ?=1. Let ?be the boundary of ?. If ?⃗=<?,?,?>, compute the total flux over ?in two ways:(a)Directly as a surface integral.Include a sketch of ?in your answer (b)As a triple integral using the Divergence Theorem

Find the solution to the boundary value problem:

?^2?/??2−6??/??+5?=0,   ?(0)=10,?(1)=6

Please show me all your work, I want to know where I went wrong. Thank you!

Find the eigenfunctions for the following boundary value problem.

x²y?? ? 15xy? + (64 + ?)?y ?=? 0,    y(e^?1) ?=? 0, ?y(1) ?=? 0.

In the eigenfunction take the arbitrary constant (either c₁ or c₂) from the general solution to be 1
