10 points and brainliest its for my semester test ! see picture

The answer to this is the last option choice.

An easy way to solve this is to look at the x in each set. If two or more of the ordered pairs have the same number in the x place, then it is not a function.

The first option isn't a function becasue there are 2 "-7"

The second option isn't a function because there are 2 "1"

The third option isn't a function because there are 2 "-2"

That leaves the bottom choice the answer because none of the x's repeat.

the answer is b: 18

step-by-step explanation:

use the pythagorean theorem to .

a^2+b^2=c^2

plug 18 for "r"

the 2 legs are 18 and 24

18^2+24^2=c^2

324+576=c^2

900=c^2

c=30

30-12=18

18 is the radius

: )

answer would be 8.64 or s = 11π/4 inches

step-by-step explanation:

s = r θ  

where s = arc length  

r = radius = 3 inches  

θ = central angle in radians = ( π /180)*165  

s = 3(π/180)*165  

= 8.64 inches
