Answer:
y = [tex]\frac{36}{25}[/tex]
Step-by-step explanation:
y ∝ [tex]\frac{1}{x^2}[/tex]
=> y = [tex]\frac{k}{x^2}[/tex] --------------(1)
Now, y = 4 and x = 3.
Putting in (1)
=> 4 = [tex]\frac{k}{9}[/tex]
=> k = 4*9
=> k = 36
Now, y = ?, when x = 5
Putting in (1)
=> y = [tex]\frac{36}{5^2}[/tex]
=> y = [tex]\frac{36}{25}[/tex]
