Answer:
3/4
Step-by-step explanation:
Answer: The answer is C, and D.
A = 90 degrees
B = 50 degrees
D = 140 degrees
E = 40 degrees
HOPE THIS HELPS!
The correct answer is (C)!
Since the area of the circle is 400π, 150π/400π = 135/360.
To find the vertex use -b/2a (for the x value which is also the axis of symmetry)
So 2/-2 = -1 Therefore the axis of symmetry is x=-1 Plug in for the y value:
y= -(-1)^2 -2(-1) + 1 y=-1 + 2 + 1 y=2 Vertex (-1,2)
