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
X=is the number
We can sugget this equation:
8(x-3)=x+25
8x-24=x+25
8x-x=25+24
7x=49
x=49/7
x=7
answer: the number is 7.
Answer:
A, 55, 55
B, 30, 30
E, 45, 90
Are the possible choices for the measures <A and <C. Hope this helps!
