Question

The rectangular coordinates of a point are given. Express the point in polar coordinates with $$r \geq 0 \text { and } 0 ^ { \circ } \leq \theta < 360 ^ { \circ } \text {. }$$
-$( 0 , \sqrt { 7 } )$
A) $\left( \sqrt { 7 } , 90 ^ { \circ } \right)$
B) $\left( \sqrt { 7 } , 270 ^ { \circ } \right)$
C) $\left( 7,270 ^ { \circ } \right)$
D) $\left( 7,90 ^ { \circ } \right)$

The point $(0, \sqrt{7})$ is on the positive y-axis. In polar coordinates, this corresponds to a distance $r = \sqrt{7}$ from the origin and an angle $\theta = 90^\circ$ from the positive x-axis.
