Let's check the dot product .

v.w = 5(4)-2(10) = 20 -20 =0

So the dot product is not 20 . And since the dot product is zero, so they are perpendicular.

And the y component of w is 10.

So correct options are first and third .

B because you are looking for an equation in the problem so if it starts at 16 and you are adding 2 gallons per hour you get 16+2x. Then for the other tank you start with 20 gallons and you are loosing 3 gallons per hour so you get 20-3x. To solve the equation you make them = each other so then you have 16+2x=20-3x.
