Answer:
The answer is 30
Step-by-step explanation:
To get a.b
For a = <wa, za> and b = <wb, zb>, the dot product represents multiplication sign.
We say,
a•b = (wa)(wb) + (za)(zb)
The next step is to substitute the given information into the above equation we generated.
Then we say,
a•b = 5•4 + 2•5
a.b = 20 + 10
a•b = 30
The answer is 30
