Answer:
6a
Step-by-step explanation:
AB = √[(3a - -3a)² + (0)²]
⇒ AB = √[(3a + 3a)² + (0)²]
⇒ AB = √[(6a)² + (0)²]
The magnitude of the vector is √(7^2+12^2)=√(49+144)=√193
The direction is α=arctan(y/x)=arctan(12/-7)≈-59.74 however this is relative to the negative x-axis so we add 180° to get the standard angle...180-59.74=120.26°
So the vector is √193 @ 120.26°
I think for this item we lack or missed out to include in the given the number of songs that Nick sold during that same year. However to determine the number of times that the number of songs that Nick sold than that of Bianca, we just have to divide the number of songs that Nick sold by the number of songs that Bianca did.

Answer:
C
Step-by-step explanation:
The average rate of change of f(x) in the closed interval [ a, b ] is
Here [ a, b ] = [ 1, 3 ]
f(b) = f(3) = - 8 ← from graph point (3, - 8 )
f(a) = f(1) = 0 ← from graph point (1, 0 )
Then
average rate of change = = = - 4 → C
