Write the theoretical demand equation using the appropriate variable names you created when you prepared data for analysis. The variable names should be very short and must be in capital letters. For instance, QTY for Y, PRPIZZA for X1, PRSDRK for X2. Note that if you used QTY for quantity, use QTY in the estimating demand equation rather than Y. Remember to use the exact same variable names you used in the data. In other word, do NOT use Y and X1, X2, X3, and so on, as done in the textbook. I am trying to teach you a proper way of teaching you how to prepare a technical paper.

A3-mm-thick panel of aluminum alloy (k 177 w/m-k, c 875 j/kg-k and ? = 2770 kg/m) is finished on both sides with an epoxy coating that must be cured at or above t,-150°c for at least 5 min. the production line for the curing operation involves two steps: (1) heating in a large oven with air at ts,0-175°c and a convection coefficient of h, 40 w/m2. k, and (2) cooling in a large chamber with air at 25°c and a con- vection coefficient of he 10 w/m2.k. the heating portion of the process is conducted over a time interval te which exceeds the ime required to reach 150°c by 5 min (h = r + 300 s). the coating has an emissivity of ? = 0.8, and the temperatures of the oven and chamber walls are 175 and 25°c, respectively. if the panel is placed in the oven at an initial temperature of 25°c and removed from the chamber at a safe-to-touch tempera ture of 37°c, what is the total elapsed time for the two-step curing operation?
