how can i find out if relationship is proportional from the table and determine if the table is proportional

So the formula to find the equation for proportional relationship is the x stands for your first set of numbers, the y stands for your second set of numbers, and the x stands for the constant of proportionality. And if you have a table then you can divide each set of numbers and if you get the same rate then it's proportional. Hope this helps!

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
