For 1983 through 1989, the per capita consumption of chicken in the U. S. increased at a rate that was approximately linear. In 1983, the per capita consumption was 36.7 pounds, and in 1989 it was 46 pounds. Write a linear model for per capita consumption of chicken in the U. S. Let t represent time in years, where t = 3 represents 1983. Let y represent chicken consumption in pounds.

as we know our atmosphere or air have different levels. every level has other gasses, and every gas has another permeability. when the light comes from lower permeability to higher permeability, it changes its direction. so that means that when the light comes from the moon to the earth, it changes it's direction many more times. it basically means that the shape of the light part of the moon is changed on the earth.
