Answer:
We have the following two vectors given: a=(15,25) and b=(8,5) and using the last formula we got:
[tex] a.b = 15*8 + 25*5 =245[/tex]
And the dot product would be 245 for this case
Step-by-step explanation:
For this case the dot product is defined for two vectos a=(ax, ay), b=(bx,by):
[tex] a.b = a_x*b_x +a_y b_y[/tex]
We have the following two vectors given: a=(15,25) and b=(8,5) and using the last formula we got:
[tex] a.b = 15*8 + 25*5 =245[/tex]
And the dot product would be 245 for this case
