Answer:
the vertex is (-7,-90)
the focus is ( -7, -359/4)= (-7,-89.75)
semi-axis length; 1/4=0.25
focal parameter: 1/2=0.5
eccentricity;1
directrix: y=-361/4
Step-by-step explanation:
Answer: B) one
This one point is point U since it is on line segment CD. In contrast, a point like point E is not on line CD, so E is not collinear with C and D.
9x^2-16y^2=
(3x+4y)(3x-4y)
Answer:
Original: 360 degrees
Opposite: 180 degrees
Step-by-step explanation:
I have no idea where 360 degrees for the full rotation. But that wasn't necessary.
How to calculate Opposite:
360/2=180
