# In pyhton! We could, in principle, represent a polynomial as a list. For instance, we could write 1+2x−3x2+2x41+2x−3x2+2x4 as [ 1,2,-3,0,2 where the ith index corresponds to xixi . If we wrote a polynomial this way, we would also like an easy way to evaluate that polynomial for a specified value of xx ; i. e., for x=1.5x=1.5 , 1+2×1.5−3×1.52+2×1.54=7.3751+2×1.5− 3×1.52+2×1.54=7.375 Compose a function polyeval( coefs, x ) which accepts a list of polynomial coefficients from lowest to highest order (as above) and a value x at which to evaluate the polynomial, and returns a float corresponding to the value of the polynomial evaluated at x. A good way to start your code would be: def polyeval( coefs, x ): value = ??? # an accumulator pattern # with some kind of loop here return value For instance, polyeval( [ 1,1,0,1 ],1 ) (1+x+x31+x+x3 for x=1x=1 ) should return 3.0. polyeval( [ 0,1,0,-2,1 ],-1 ) (x−2x3+x4x−2x3+x4 for x=−1x=−1 ) should return 2.0.

Two flowing streams of argon gas are adiabatically mixed to form a single flow/stream. one stream is 1.5 kg/s at 400 kpa and 200 c while the second stream is 2kg/s at 500 kpa and 100 ? . it is stated that the exit state of the mixed single flow of argon gas is 150 c and 300 kpa. assuming there is no work output or input during the mixing process, does this process violate either the first or the second law or both? explain and state all your assumptions.
