Answer:
y= 15
Step-by-step explanation:
Y= Kxz
y=6 x=1/2 z=6
15= K (1/2) (6)
15= K (3)
K= 5
SO
y= (5) (1/2) (6)
Y= 15
Answer:
k = 5
Step-by-step explanation:
Given y varies jointly as x and z then the equation relating them is
y = kxz ← k is the constant of variation
To find k use the condition y = 15 when x = [tex]\frac{1}{2}[/tex] and z = 6 , then
15 = k × [tex]\frac{1}{2}[/tex] × 6 = 3k ( divide both sides by 3 )
5 = k
