Which set of ordered pairs does not represent a function? O {(-7, -8),(-7,5),(-6,0),(-1,8)} O {(-2,4), (6,-5),(-6, -9), (1, -5)} O {(8,-2), (3,9),(-1,-5), (-3,9)} O {(9,7), (2,7), (-8,-3), (-1,1)}​

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

the answer is 15.50 for one mile

b) is slope: 0   y- intercept 15.5
