Consider an isosceles triangle a with base 10 and height 12. consider another triangle b formed using vertices which are the center of the sides of triangle a. consider another triangle c whose vertices are similarly formed from b. repeat this process ad infinitum. express the sum of the areas of all such triangles using a series and its closed form sum. compute the areas (a) by using only the first two terms of the series and (b) by using the closed form of the series sum. write a program to find the sums and use shifts to compute. what is the difference in the two computed sums?

First, think of what you know. you know that the number t the end of the equation will need to be subtracted because it is the money he lost from buying the lawn mower. and your first two weeks have negative profit, so that tells you that c and d are wrong. now you can plug any of the weeks into a and b to see which one works. i'll start with plugging week 1 into a.this isn't right because it says your answer for week one should be -90.so now we need to try the same thing with b.this one got you the right answer, (sometimes if you only check with one of the weeks multiple will work so you need to check with more of the weeks, but it worked out fine here)this means that b is the correct answer.let me know if you need more clarification. i hope this : )
