Question

if y varies inversely as the square root of x, what is the constant of proportionality if y=6 when x=4?

Answer 1

Answer:

k=12

Step-by-step explanation:

y varies inversely as the square root of x

$y=\frac{k}{\sqrt{x} }$

for some non-zero constant k

y=6 and x=4

$6=\frac{k}{\sqrt{4} } \\k=12$
