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.
originally: 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-> \(h_n=9\times\left({7\over8}\right)^n\)
so how much would be left?
IS IT RIGHT electro kid
it will be \(9\times\left({7\over8}\right)^8\)
how did you get 63/8?
that is after the first day.. look at my elaboration.. after "n" number of days... \(h_n\)
the question asks you to obtain that expression!
