A university begins Year 1 with 80 faculty. They hire 4 faculty each year. During each year 10% (rounded to the nearest integer) of the faculty present at the beginning of the year leave the university. For example‚ in a year where there are 73 faculty at the beginning of the year‚ 7 would leave the university at the end of the year. The university wants to know how many faculty they will have at the end of year 10. The resulting spreadsheet can be found below. The formula copied down from E10 to

Unit 4 Assignment 1 Copper vs. Fiber Paper Copper wire is found in most household electric or electrical related devices. One advantage of copper wire is its conductivity. Copper wire is second only to silver wire in level of conductivity meaning it will accept a current more so than almost any other type of wire. Copper wire is also heat resistant and can handle high levels of charge without many issues with overloading the wire. Copper in itself is also resistant to corrosion. This helps

reacted aluminum foil with a copper chloride solution‚ and determined the amount of metal that should be produced‚ given the amount of aluminum used. First‚ we obtained a piece of aluminum with a mass of 0.809 g‚ and reacted it with 100 mL of Copper II Chloride‚ after heating the solution. Then‚ we filtered out the copper separated in the reaction using filter paper‚ massing 0.751 g. Once all the solution was filtered‚ we massed the new filter paper filled with copper‚ after letting it dry overnight
