Answer:
u · v = - 13
Step-by-step explanation:
dot product of u = 〈3, - 4〉and v =〈- 7, - 2〉
(3î - 4j) • (- 7î - 2j) = - 21 + 8 = -13

The dot product of u = 〈3, - 4〉 and v =〈- 7, - 2〉 as u · v = - 13.
The dot product of the two function u and v can be calulated as
u · v = (xî + yj) • (aî + bj)
The dot product of u and v is a scalar because dot product is always a scalar.
The dot product of u = 〈3, - 4〉 and v =〈- 7, - 2〉
u · v = (xî + yj) • (aî + bj)
= (3î - 4j) • (- 7î - 2j)
= - 21 + 8
= -13
