Answer:
d. parabola, 0°
Step-by-step explanation:
y² + 8x - 0
y² = -8x
Where x = cos t , y = sin t
Sin² t = -8 Cos t
1 - Cos² t = -8 Cos t
- Cos² t + 8 Cos t + 1 = 0
t = 2лπ ± (3 + √10) , л∈Z
Angle of rotation
So... T = 1.25?, if this isn't correct ask the question again.. i don't fully get it
Step-by-step explanation:
-9(-10-9)
90+81
171
hope it helps..
