### The quantity y is partly constant and partly varies inversely as the square of z....

The quantity y is partly constant and partly varies inversely as the square of z. When y = 6, z = 2 and when y = 4.5, z = 4. Find y when z = 10?

y is partly constant
y varies inversely as the square of z
y=k/z^2
when y=6 , z=2
therefore k= 6×4 k=24
when y =4.5 and z=4 k=16x4.5=72
y=? when z=10
y=k/z^2=100y =1 y= 1/100

• Aliyu: for k = 24 y= 24/100 y =0.24
for k=72, y= 72 /100 y=0.72
