Answer
$x~~~~~~~~~~~~~~~~~y=\frac{20}{x^2}$
$2~~~~~~~~~~~~~~~~~~~~~~5$
$4~~~~~~~~~~~~~~~~~~~~~\frac{5}{4}$
$6~~~~~~~~~~~~~~~~~~~~~\frac{5}{9}$
$8~~~~~~~~~~~~~~~~~~~~~\frac{5}{16}$
$10~~~~~~~~~~~~~~~~~~~\frac{1}{5}$
Work Step by Step
$y=\frac{k}{x^n}$
$k=20$ and $n=2$
$y=\frac{20}{x^2}$
$x=2$:
$y=\frac{20}{4}=5$
$x=4$:
$y=\frac{20}{16}=\frac{5}{4}$
$x=6$:
$y=\frac{20}{36}=\frac{5}{9}$
$x=8$:
$y=\frac{20}{64}=\frac{5}{16}$
$x=10$:
$y=\frac{20}{100}=\frac{1}{5}$
$x~~~~~~~~~~~~~~~~~y=\frac{20}{x^2}$
$2~~~~~~~~~~~~~~~~~~~~~~5$
$4~~~~~~~~~~~~~~~~~~~~~\frac{5}{4}$
$6~~~~~~~~~~~~~~~~~~~~~\frac{5}{9}$
$8~~~~~~~~~~~~~~~~~~~~~\frac{5}{16}$
$10~~~~~~~~~~~~~~~~~~~\frac{1}{5}$
