Question

Pls explain the question of this sum

Answer 1

Answer:

y= k * sqrt(x)

K=6

Step-by-step explanation:

Y varies directly to square foot of x

Means

y=k× sqrt(x)

Where k is the proportionality constant

Now put the values of y and x given in question

=> 24= k* sqrt(16) Ans(i)

=> 24 = k * 4

=> k= 6. Ans (ii)

Now use this value k to find any value of y if x is given
