Answer the following questions by applying the lecture discussions, book readings and research that you have done on the topic.Provide data to support your answer and organize your information clearly. DEMONSTRATE in your discussion post that you understand the concepts associated with this question1. Describe in our own words what you believe is the range of household income of the lower class, middle class, and upper class. Also, What do you imagine to be the education levels, occupations, and material signifiers (home, vehicle, and so on) associated with each of these class statuses.2.

Describe why you selected the location and why you believe that it can be identified as one of the selected class.You can include pictures of the location selected to support your example.
Obtain the general solution of the following DEs: i. y′′′ + y′′ − 4y′ + 2y = 0 ii. y(4) + 4y(2) = 0 iii. x(x − 2)y′′ + 2(x − 1)y′ − 2y = 0; use y1 = (1 − x) iv. y′′ − 4y = sin2(x) v. y′′ − 4y′ + 3y = x ; use y1 = e3x vi. y′′ + 5y′ + 6y = e2xcos(x) vii. y′′ + y = sec(x) tan(x)
