Answer: Determine whether each set equipped with the given operations is avector space. For those that are not vector spaces identify the vector space axioms that fail.a). The set of all pairs of real numbers of the form (x,y), where x ≥ 0, with the standard operations on R^2.b). The set of all triples of real numbers with the standard vectoraddition but with scalar multiplication defined by k(x,y,z) = (k^2x,k^2y,k^2z)c). The set of all 2 x 2 invertible matrices with the standard matrix addition and scalar multiplication
Step-by-step explanation:
A triangle a can’t have more than 1 obtuse angle because all angles have to equal 180 degrees, and an obtuse angle is larger then 90 degrees. If it had more than 1 obtuse angle, the angles wouldn’t equal 180 degrees and you wouldn’t be able to make a third angle.
