alekssr [168]
<u>Domain</u>          <u>Range</u>
    -1                    3
     0                    5
     2                    8
     3

The domain of the relation {(2, 8), (0, 8), (-1, 5), (-1, 3), (-2, 3)} is {-1, 0, 2, 3}.

Y is inversely proportional to the square root of x if y=3 when x=25 find y when x is 9
irga5000 [103]

Answer:

y=5

Step-by-step explanation:

\textsf{If }y \textsf{ is \underline{inversely proportional} to the square root of }x, \textsf{ then}:

y \propto\dfrac{1}{\sqrt{x}} \implies y=\dfrac{k}{\sqrt{x}}\quad \textsf{(where k is some constant)}

\textsf{When }x=25, y = 3:

\implies 3=\dfrac{k}{\sqrt{25}}

\implies 3=\dfrac{k}{5}

\implies k=15

Inputting the <u>found value of k</u> into the equation:

\implies y=\dfrac{15}{\sqrt{x}}

To find the value of y when x is 9, <u>substitute</u> x = 9 into the found equation:

\implies y=\dfrac{15}{\sqrt{9}}

\implies y=\dfrac{15}{3}

\implies y=5
