Answer:
k = [tex]\frac{1}{4}[/tex]
Step-by-step explanation:
Given that j varies jointly with g and v then the equation relating them is
j = kgv ← k is the constant of variation
To find k use the condition j = 3 when g = 4 and v = 3
k = [tex]\frac{j}{gv}[/tex] = [tex]\frac{3}{4(3)}[/tex] = [tex]\frac{3}{12}[/tex] = [tex]\frac{1}{4}[/tex]
