(a1, 22, ..., A. In the problems that follow, the set R” consists of all ordered n-tuples , an) of real numbers ai. Addition is defined by the rule (a1, Q2, ..., An) + (b1,b2, ..., bn) = (a1 + b1, a2 + b2, ..., An + bn) and scalar multiplication is defined by c(a1, A2, ..., An) = (cai, ca2, ..., can). Thus, R” is a vector space over the field R under these two operations. 2 1. Let W be the subset of Ra consisting of all ordered (a1, a2) such that al > 0 and a2 > 0. Is W a subspace of R?? pairs
