For 1983 through 1989, the per capita con-
sumption of chicken in the u. s. increased at a
rate that was approximately linear. in 1983,
the per capita consumption was 36.8 pounds,
and in 1989 it was 50 pounds.
write a linear model for per capita con-
sumption of chicken in the u. s. let t repre-
sent time in years, where t = 3 represents
1983. let y represent chicken consumption in
pounds.

Along wire of diameter 1 mm is submerged in an oil bath of temperature ∞ 31°c. the wire has an electrical resistance per unit length of 0.01 ω/m. if a current of 103 a flows through the wire and the convection coefficient is 500 w/m2·k, what is the steady-state temperature of the wire? from the time the current is applied, how long does it take for the wire to reach a temperature that is within 1°c of the steady-state value? the properties of the wire are 8000 kg/m3, 500 j/kg·k, and 20 w/m·k.
