Heather wanted to measure the effects of erosion on a mound of soil in her backyard. The area she measured was 9 inches in height. During a storm it eroded 1/8 every day for 8 days. Write an expression that can be used to find the height of the mound of soil after the storm and simplify the expression.

Best ResponseYou've already chosen the best response.1originally: 9in every day (1/8)th gets eroded.. how much is left out? > 7/8th end of day 1> \(h_1=9\times{7\over8}\) end of day 2>\(h_2=h_1{7\over8}=9\times\left({7\over8}\right)^2\) and so on.. end of nth day> \(h_n=9\times\left({7\over8}\right)^n\)
