Determine e, k, and identify the type of conic for r =3/2-6 cos theta.

The answer is (c) ⇒ e = 3 and k = 1/2 , conic: hyperbola

Step-by-step explanation:

∵ r = ek/(1 ± ecosФ)

∵ r = 3/(2 - 6cosФ) ⇒ ÷ 2 up and down

∴ r = (3/2)/(1 - 3cosФ)

∴ e = 3

∵ ek = 3/2 ⇒ 3k = 3/2

∴ k = 1/2

∵ e > 1

∴ The conic is hyperbola

60

step-by-step explanation:

every triangle measures a total of 120 degrees. you have to find angle c. we know that isosceles triangles angles are equal. 60 degrees plus 60 degrees gives you 120.
