Show that a system described by 
is invertible and that a system described by y[n] = x[2n] is not invertible.
What will be an ideal response?
If 
then 
But 2n can never be odd.
Therefore y[n] = x[2n] and the system is invertible.
If y[n] = x[2n], then y[n/2] = x[n]. But when n is odd, y [n/2] is undefined.
Therefore the system is not invertible.

Given the following data, determine the mixture enthalpy at 300 K and 0.1 MPa for a system that contains 5 moles of component (1) and 15 moles of component (2):
Repeat Problem 19-7 using two different depths of untreated aggregate bases of 6” and 12”. Highway contractors in your area can furnish rates for providing and properly laying an asphalt concrete surface and untreated granular base. Assume a structural coefficient of 0.12 for the base course. If these rates are available, determine the cost for constructing the different pavement designs if the highway section is 5 miles long and the lane width is 12 ft. Which design will you select for construction?
