For the following relations, determine whether they are reflexive, symmetric, or transitive. for each property, either give a proof that the property holds, or a counterexample to the property. (a) r is the relation on r\{0} defined by xry iff 0 > xy 1 (b) s is the relation on q\{0} defined by x y iff ∃n ∈ z x = ny

hi how are you doing today, if you need just ask me.

step-by-step explanation:

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

b). 4320 have a nice day
