What is the vertex form of the equation?

- (x - 6)^2 + 32

Step-by-step explanation:

-x^2 + 12x- 4

= - (x^2 - 12x) - 4

= - [(x - 6)^2 - 36) - 4

= -(x - 6)^2 + 32

34.5 cm

step-by-step explanation:

generally for a circular segment of angle, θ° and radius r

arc length

= (θ/360) x circumference

= (θ/360) x 2πr

in our case, θ = 60°, π=3.142 and r = 33 cm

substitute into above formula

arc length

= (60/360) x 2(3.142)( 33) = 34.5 cm
