Question

of x and y vary Enversely and x = 40 when y.520 , find y' when a= 520​

Answer 1

Step-by-step explanation:

It is given that y varies inversely with x.

Hence, mathematically it can be written as y ∝ (1 / x)

Therefore, y = k / x (where k is the constant of proportionality)

Now, substituting y = 40 and x = 5 in the above equation we get,

40 = k / 5 or k = 200
