Question

x varies directly as y square. Given that for y = 3 , x = 2. The value x when y = 5 will be -

Answer 1

Answer:

50/9

Step-by-step explanation:

x varies directly with y²

That gives x=k y²  , where k is the constant

For value of y= 3 and x=2

We have 2 = k 3² = k 9 ⇒ k = 2/9

For value of y = 5

We have  x =(2/9)*5²=50/9

Value of x=50/9
