The equation of parabola is 
Comparing with the vertex form of the parabola: 
Hence, the vertex of the parabola is given by (h,k) = (1, -2)
Now, vertex is the midpoint of the focus and the point on the directrix.
Distance, between vertex and focus is p and that of point on the directrix is p.
Now, let us find p
Thus, the focus is given by
And the directrix is given by
Since, a >0 hence, it is an upward parabola.
The graph is shown in the attached file.
I believe it’s 90 I’m not sure but
Answer:
45
Step-by-step explanation:
all angles have to add up to a total of 360, so the other 3 angles equal 270 and there's two more angles that need to split 90° equally
Answer:
Slope: 0
y-intercept: (0,-1)
Step-by-step explanation:
Side JL is 4√2 recall that in a 30-60-90 right triangle the hypotenuse is 2 times the size of the short leg.
JL also serves as the hypotenuse of the 45-45-90 triangle JML. The ratio of side lengths in this triangle is 1:1:√2
So we can see that the value of x = 4
