Find the dot product for u = { 3, -2} and v = {-5, 1}

Sagot :

Answer:

Answer is -17

Step-by-step explanation:

Express in vectorial form:

[tex]{ \rm{u = \binom{3}{ - 2} }} \\ \\ { \rm{v = \binom{ - 5}{1} }}[/tex]

• Then the dot product:

[tex]{ \rm{u•v = (3 \times - 5) + ( - 2 \times 1)}} \\ \\ { \rm{u•v = - 15 - 2}} \\ \\ { \rm{u•v = - 17}}[/tex]
