Question

review the four points shown on the polar coordinate system. which point has coordinates (5, -\frac{7\pi}{6})? point a point b point c point d

Explanation:

Step1: Analyze polar - coordinate concept

In polar coordinates $(r,\theta)$, $r = 5$ is the distance from the origin and $\theta=-\frac{7\pi}{6}$.

Step2: Convert negative angle

$-\frac{7\pi}{6}+2\pi=\frac{5\pi}{6}$.

Step3: Locate the point

A point with $r = 5$ and $\theta=\frac{5\pi}{6}$ corresponds to point A on the given polar - coordinate system.

Answer:

point A
