Part (a)
Lets say we had the two general vectors
u = (a,b)
v = (c,d)
The dot product is
u dot v = a*c + b*d
-------------------
Apply that rule to these specific vectors
u = (5, -2)
v = (0, 1)
So we get
u dot v = 5*0 + (-2)*1
u dot v = 0 - 2
u dot v = -2
Therefore,
(u dot v)*w = -2*(-1, -3)
(u dot v)*w = ( -2*(-1), -2(-3) )
(u dot v)*w = (2, 6)
Answer: (2, 6)
=============================================
Part (b)
u = (5, -2)
5u = 5*(5, -2)
5u = (5*5, 5*(-2))
5u = (25, -10)
5u dot v = (25, -10) dot (0,1)
5u dot v = 25*0 + (-10)*1
5u dot v = 0 - 10
5u dot v = -10
Answer: -10
Answer:
10-x
Step-by-step explanation:
The total amount is made up of movies and music
total = movies + music
10 = x+ music
Subtract x from each side
10-x = x+music-x
10-x = music
Answer:
Step-by-step explanation:
Step 1: Divide 150 by 100 which will give you 1.5
Step 2: Multiply 1.5 by 12 which will give you 18
Answer: So the answer is 18% is left handed!

Functions are graphs that do not have repeating x-values. The domain of a function are the x-values and the range are the y-values in a function
