Answer:
[tex]a.b =2.2[/tex]
Step-by-step explanation:
We are given the following in the question:
[tex]a=\langle -2,3 \rangle, b=\langle 0.7, 1.2 \rangle[/tex]
We have to find the dot product.
Formula:
[tex]a = \langle x_1,x_2\rangle\\b = \langle y_1.y_2\rangle\\a.b = x_1y_1 + x_2y_2[/tex]
Putting the corresponding values we get,
[tex]a.b = (-2.(0.7)) + (3.(1.2))\\=-1.4+3.6\\=2.2[/tex]
[tex]a.b =2.2[/tex]
