to convert to an equation multiply by k the of variation
Rightarrow y=k* x z^ 2 = kx z^ 2
to find k use the given condition
y = 20 when x = 50 and z = 5 y= kx z^ 2 Rightarrow k= yz^ 2 x = 20*25 50 =10 equation is y = (10x)/(z ^ 2) when x = 3 and z = 6 then y= 10*3 36 = 30 36 = 5 6
Answers & Comments
Answer:
x and y divided by the square of z
y=56
Step-by-step explanation:
the initial statement is y propto x z^ 2
