Determine which of the following subsets of r 3 are subspaces. briefly explain. i) the set s1 of vectors (x, y, z) ∈ r 3 such that xyz = 0 ii) the set s2 of vectors (x, y, z) ∈ r 3 such that x + y + z = 0 iii) the set s1 of vectors (x, y, z) ∈ r 3 such that y 2 + z 2 = 0 iv) the set s1 of vectors (x, y, z) ∈ r 3 such that y 2 − z 2 = 0

answer: b 56, 250

explanation:

hi,

henry is an economist and wants to understand the relationship between inflation and consumer spending habits. for his research, he needs the consumer price index for 2014 and the inflation rate. based on the prices of goods given, what will he find to be the cpi and inflation rate for 2014? assume that a consumer’s basket for three consecutive years consists of the following:
