f(x) = -2(x − 4^)2+ 2
The vertex is (4,2)
so the axis of symmetry is is x=4
g(x) = 5x^2− 10x + 7
h= -b/2a = 10/2(5) = 10/10 =1
The axis of symmetry is at x=1
h(x) the axis of symmetry is at x=-2

As stated the area of the circle is 85π ft2. The area of the sector BAC is a portion of this full circle area. the sector is made of 2 radii and arc that has rotated by 36°.
the magnitude of the central angle in the circle is 360°
Area for 360° central angle - 85π ft2
then the area for 1° = 85π ft2/360°
the area of 36° sector = 85π ft2/360° x 36°
= 8.5π ft2
