Identify the graph of the equation. What is the angle of rotation for the equation?
y2 + 8x - 0
a hyperbola, 30°
b. parabola; 90°
c. hyperbola; 180°
d. parabola, 0°

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

they would have to work 32 hours.

you estimate that the angle of elevation to the top of the 86th floor (the observatory) is 82 .the total height of the building is another 123 meters above the 86th floor.
