Answer:
[tex]y = \frac{8 \times \sqrt{21} }{ \sqrt{x \\ } } [/tex]
Step-by-step explanation:
[tex]y = \frac{k}{ \sqrt{x} } [/tex]
because y is inversely proportional to the square root of x
Then we must find the value of k using the information
[tex]8 = \frac{k}{ \sqrt{21} } [/tex]
That is
[tex]k = 8 \times \sqrt{21 \\ }[/tex]
