Answer:
see below
Step-by-step explanation:
f(x)= -(x-2)^2 +4
This is the vertex form of the equation for a parabola
y= a ( x-h)^2 +k where (x,k) is the vertex of the parabola
a = -1 h= 2 k = 4
The vertex is ( 2,4)
Answer:
A
Step-by-step explanation:
The area of the shaded segment
= area of sector OAB - area of ΔOAB
area of sector = area of circle × fraction of circle, that is
A = πr² × fraction of circle
= π × 6² ×
= 36π × = 6π units²
Area of triangle = 0.5 × 6 × 6 × sin60° = 18 × = 9 units²
Hence
area of shaded segment = 6π - 9 units² → A
