Question

Given u = LeftAngleBracket StartRoot 3 EndRoot, negative 1 RightAngleBracket and v = ⟨3, –4⟩, what is u · v?

Answer 1

D.

Explanation:

just took test

Answer 2

3√3+4

Explanation:

Given the vectors u = <√3, -1> and v = <3, -4>

u · v = <√3, -1> *<3, -4>

u · v = 3√3 + (-1*-4)

u · v = 3√3+(4)

u · v = 3√3+4

Hence the dot product is 3√3+4
