The number of foreign students $F$ (in thousands) enrolled in colleges in the United States from 1992 to 2002 can be approximated by the model.

$$F=0.004 t^4+0.46 t^2+431.6, \quad 2 \leq t \leq 12$$

where $t$ represents the year, with $t=2$ corresponding to 1992. Find the average rate of change of the model from 1992 to 2002. Interpret your answer in the context of the problem.

A converging-diverging nozzle operates at steady state. Air as an ideal gas with k = 1.4 enters the nozzle at 500 K, 6 bar, and a Mach number of 0.3.
