Let V := R 2 . Let + denote the usual (vector) addition on R 2 . Define a scalar multiplication ∗ by assigning α ∗ (x, y) = (αy, αx), for any α ∈ R and (x, y) ∈ R 2 . Then (V, ∗, +) is not a vector space.

step-by-step explanation:

answer: sine

step-by-step explanation:

answer: first option i.e. 'a' is correct.

step-by-step explanation:

since we have given that

number of minutes to wrap a small gift box = 4 minutes

we need to find the number of gifts to be wrapped in 5 minutes

since there is a direct variation, as the number of minutes will increase with   number of gifts to be wrapped.

so, let the number of gifts to be wrapped in 5 minutes be x.

so, it becomes,

hence, first option 'a'   is correct.
