Chapter 10 - Conics, Parametric Equations, and Polar Coordinates - 10.4 Exercises - Page 722: 10

Rectangular coordinates: $(3.35,8.62)$

In polar coordinates, the first number represents the value for $r$, and the second number represents the value for $\theta$. $(9.25, 1.2)$ Thus: $r = 9.25$ and $\theta = 1.2$ Knowing that $x = rcos(\theta)$ and $y = rsin(\theta):$ $x = rcos(\theta) = (9.25)(cos(1.2)) \approx 3.35$ $y = rsin(\theta) = (9.25)(sin(1.2)) \approx 8.62$
