Answer:
The correct option is c.
Step-by-step explanation:
Given that,
u = 7i+4j and v = 2i-3j
We need to find the product of u and v. The dot product of two vectors is given by :
![u{\cdot}v=(7i+4j){\cdot} (2i-3j)\\\\=(7i)(2i)+(4j)(-3j)\\\\=14-12\\\\=2](https://tex.z-dn.net/?f=u%7B%5Ccdot%7Dv%3D%287i%2B4j%29%7B%5Ccdot%7D%20%282i-3j%29%5C%5C%5C%5C%3D%287i%29%282i%29%2B%284j%29%28-3j%29%5C%5C%5C%5C%3D14-12%5C%5C%5C%5C%3D2)
So, the dot product of u and v is equal to 2.
