F(x)=x^2−x−1

over which interval does f have an average rate of change of zero?

choose 1

(choice a)

2≤x≤3

(choice b)

−3≤x≤−2

(choice c)

−1≤x≤2

(choice d)

−5≤x≤5

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

nope lol
