consuming leisure. If he spends his time gathering coconuts‚ he has less time for leisure but gets to eat the coconuts. We can depict Robinson production opportunities and preferences over the two goods. At this point‚ the slope of the indifference curve must equal the slope ofthe production function by the standard argument: if they crossed‚ therewould be some other feasible point that was preferred. The utility maximizing choice for Robinson must be the point at which the highest indifference

VIBRATIONAL-ROTATIONAL SPECTRA OF HCl Physical Chemistry Laboratory II‚ CHEM 3155.001 April 20‚ 2012 Introduction and Objective The experimental objective of this lab was to collect an IR spectrum of gaseous HCl and from it the experimental rotational constant‚ B‚ and fundamental vibration frequency‚ v0‚ can be calculated(1). The concept of infrared spectroscopy deals with the infrared region of the electromagnetic spectrum. Molecules absorb at specific resonant frequencies that are characteristic

equation f(x)=ax+b‚ where a is the slope and b is the y-intercept. Linear functions form a straight line when graphed and maintain a constant slope. It can be an increasing or decreasing function. For example‚ a lemonade stand sells a cup of lemonade for twenty-five cents. Graphed‚ x would be the cups sold‚ and y would be income. If the people running the stand start with no money‚ then the y-intercept will be zero. Because each cup cost twenty-five cents‚ the slope is twenty-five. The situation can
