Y is inversely proportional to the square root of x. When y = 7, x= 2.25,
write y in term of x

X is inversely proportional to the square root of y. When x=2, y=16. What is the estimated value of y when x=1024? How is that calculated?

As we know when proportional sign is replaced by '’=” then a proportional constant comes in the equation hence,

x=k.y^(-1/2) …….eq1

We will find value of k from given Condition

When x=2 and y=16 then

2=k.(16)^(-1/2)

2=k/4

k=8 ………..eq2

Using eq2 in eq1 we have

x=8.y^(—1/2) ……..eq3

We have to find to find x=1024 then find y

1024=8.y^(—1/2)

y^(1/2)=8/1024

y= (1/128)^2

y=2^(-14)

x=0
