1.	5.y varies directly as square root of x. When x = 16, y = 24. Find the constant olvariation and equation of variation.
Answer» It is given that , y varies directly as square root of x . x = 16 , y = 24 y = k × √x ( k is a constant ) 24 = k × √16 24 = 4k 24/4 = k 6 = k Therefore ,Required constant = k = 6 And Equation y = 6√x

5.y varies directly as square root of x. When x = 16, y = 24. Find the constant olvariation and equation of variation.

Answer»

It is given that ,

y varies directly as square root of x .

x = 16 , y = 24

y = k × √x ( k is a constant )

24 = k × √16

24 = 4k

24/4 = k

6 = k

Therefore ,Required constant = k = 6

And Equation y = 6√x
