Answer:
Co-ordinates of the focus is; (0, -4)
Step-by-step explanation:
We are given;
Vertex at origin; (0, 0)
Equation of parabola; y = x²/4p
4p = -16
Now,in parabola with vertex at origin, the coordinates of the focus is usually at (0, p)
Now, from 4p = -16 we can find p
p = -16/4
p = -4
Thus coordinates of the focus is; (0, -4)
Answer:
Y=1/2x +4
Step-by-step explanation:
1/2 is the line and it starts at 4

Answer:
y=3x+7
Step-by-step explanation:
y=mx+c
we have (0,7). (x,y)
so y-7/x-0=3
multiply by (x-0) both sides to get
y-7=3x take -7 to the other side of equal sign
it will be: Y=3X+7
In the given figure,
line a & b are parallel, line l and m are parallel.
for line a and b are parallel and line l act as a transversal.
So, angle BAC and ACD are the alterantive interior angles.
Angle BAC = Angle ACD
2x = 46
i.e. Angle BAC = 46
Lines l and m are parallel, a line act as a transversal,
So, the angle BAC and angle y are the corresponding angle,
Since the pair of corresponding angles are always equal so,
Angle BAC = y
46 = y
y = 46
Answer : y = 46
