Question

Find the dot product of the given vectors.
u=9i+4j
v=3i−j

Answer 1

The dot product of u = 9i+4j and v = 3i- j is 23.

Step-by-step explanation:

The dot product of two vectors can be calculated by multiplying their corresponding components and then summing them up. In this case, the dot product of u = 9i+4j and v = 3i- j is:

u · v = (9)(3) + (4)(-1) = 27 - 4 = 23

So, the dot product of u and v is 23.
