So the "sum" means to add all of the terms: 1³ + 2³ + 3³
1³ is simply 1
2³ is 8
3³ is 27
so, from there, you just add all of those terms: 1 + 8 + 27 = 36
Answer:
B.
Step-by-step explanation:
f(x) has two complex roots and one real root.
Cos ( theta ) = cos 7π/6 = -√3/2
sin ( Theta ) = sin 7π/6 = -1/2
Coordinates of the terminal points are: ( -√3/2, -1/2 )
They are congruent if they are bisected at their midpoint
