Chapter 4 15. For discrete compounding‚ to find the EAR‚ we use the equation: EAR = [1 + (APR / m)]m – 1 = .0719‚ or 7.19% EAR = [1 + (.07 / 4)]4 – 1 EAR = [1 + (.16 / 12)]12 – 1 = .1723‚ or 17.23% = .1163‚ or 11.63% EAR = [1 + (.11 / 365)]365 – 1 To find the EAR with continuous compounding‚ we use the equation: EAR = er – 1 EAR = e.12 – 1 = .1275‚ or 12.75% 23. Although the stock and bond accounts have different interest rates‚ we can draw one time line‚ but we need to remember to

How to Form Ionic Bonds 1. Explain (step-by-step) how to form ionic bonds between Li+ and N-3. First‚ understand that all atoms want full shells. All atoms‚ except for noble gases‚ have valence electrons. These electrons are the ones on the outermost shell. All atoms either want to get rid of these electrons or gain enough to make a full shell. Metals‚ which are on the right side of the periodic table‚ have less than 4 valence electrons. This means they want to get rid of those electrons. Nonmetals

Discussion The purpose of this lab is to display the influence of retronasal olfaction when it comes to flavor. Humans have two different types of olfaction. Olfaction is the detection of chemicals in the air. These chemicals which are meant to activate odor receptors‚ are called odorants. Humans have approximately 20 million olfactory receptors‚ which is only a fraction compared to bloodhounds who have 4 billion. The first type of olfaction is called orthonasal olfaction which is inhaling. Here
