Yvaries directly as x and inversely as the square of z. y=48when x=100 and z= 5. find y when x=3 and z=12

y = 0.25

Step-by-step explanation:

Given y varies directly as x and inversely as the square of z then the equation relating them is

y = ← k is the constant of variation

To find k use the condition y = 48 when x = 100 and z = 5

k = = = 12

y = ← equation of variation

When x = 3 and z = 12, then

y = = 0.25

the mean and mad

step-by-step explanation:

this is false ^.^ lol
