Use blackslash (\) operator to solve the system of equations, ax = b, for unknown x’s and put the answer in p1. the coefficient matrix a has a dimension of 30 rows by 30 columns. all elements are zero except for those on the diagonal, subdiagonal and superdiagonal. to create a, first create a 30 × 30 matrix with all zero and then modify the non-zero elements using linear indexing. another method is to explore function diag.

step-by-step explanation:

a.   since the profit made in 2012 is equal to the profit made in 2014, the profit is           symmetric about the line y = 120,000.

step-by-step explanation:

given that megan owns a clothing boutique.

the profits of 2010, 11, are recorded and shown as follows:

years since     2010 0     1     2     3       4       5

profits made in 1000's   39       84     111     120   111     84

we find that profit gradually increases form 2010 to 2013 upto 120,   then starts decreasing.

the profits for 2012 and 2014 are the same while that of 2011 and 2015 are also the same.

this shows that there is symmetry about the line profit = 120000

hence answer is:

a.   since the profit made in 2012 is equal to the profit made in 2014, the profit is           symmetric about the line y = 120,000.
