0.4This place is meaningful to me because it is part of the county I loved, is part of the county where I grew up and is part of my childhood. This place is in the country in an old region named Appalachia, a small piece of the Appalachian Mountains, in a town named Pikeville.
Pikeville is a polluted town because of the coal industry. People live in apartment or condominium buildings because of its little space available. I grew up in one of the many buildings in Pikeville admiring from my bedroom window the beauty of the mountains, always exploring with my eyes the forest or the meadows, looking for a clean and quiet place. And, I found one on a hill in the back of the town. It is about 100 feet square, it has seven old trees, wild flowers and a lot of bugs and ants during summer time.write a short description of a place or journey as a group.Take an online test Take Now

(i) x2 + y2/x2 – y2 = 17/8
Applying componendo and dividendo rule,
x2 + y2 + x2 – y2/x2 + y2 – x2 + y2 = 17 + 8/17 – 8
2x2/2y2 = 25/9
x2/y2 = 25/9
x/y = 5/3
x : y = 5 : 3
(ii) Taking cube on both sides,
x3/y3 = 125/27
Applying componendo and dividendo rule,
x3 + y3/x3 – y3 = 125 + 27/125 – 27
x3 + y3/x3 – y3 = 152/98
