The graph of r = -10 cos θ has which of the following characteristics?
Ronch [10]

Step-by-step explanation:

If we convert

r =  - 10 \cos(x)

to a Cartesian equation,

{r}^{2}  =  - 10 r \: \cos(x)

{x}^{2}  +  {y}^{2}  =  - 10x

{x}^{2}  + 10x +  {y}^{2}  = 0

{x}^{2}  + 10x + 25 +  {y}^{2}  = 25

(x + 5) {}^{2}  +  {y}^{2}  = 25

So we have a circle with center (-5,0), with a diameter of 10.
