The value of y varies directly as the square of x and y=27 when x=9. Find the equation represents this relationship. Report the
skad [1K]

Answer:

The relation between x and y is

y=\frac13 x^2

Step-by-step explanation:

Given that,

The value of y varies directly as the square of x.

y\propto x^2

\Rightarrow y=rx^2

where r is constant of proportional.

Given that,

y= 27 and x=9

Plug y= 27 and x=9 in above relation

y=rx^2

\therefore 27=r(9)^2

\Rightarrow 27 = r.81

\Rightarrow r=\frac{27}{81}

\Rightarrow r=\frac{1}{3}

The relation between x and y is

y=\frac13 x^2
