Look at this set of ordered pairs: (9,8)
(12, 15)
(5, 7)
(4,9)
Is this relation a function?
yes
no

Yes, the given relation is a function.

Step-by-step explanation:

As given,

(4, 9)

(5, 7)

(9, 8)

(12, 15)

x                          y

4                          9

5                          7

9                          8

12                         15

As each input has different and unique output values.

So, the given relation is a function.

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
