Answer:
(4,470°)
Step-by-step explanation:
The representation that does not change the location of (4, 110°) in polar coordinates are all points that are coterminal with the given point.
The only point among the given options that is coterminal with (4, 110°) is (4, 470)°
The two points have the same magnitude and 470°-360°=110°.
Since 110° is coterminal with 470° and the two points have the same magnitude with the same sign, the two points represent the same location in polar coordinates.
The correct choice is (4,470°)
