Of x and y vary Enversely and x = 40 when y.520 , find y' when a= 520 |
|
Answer» -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 |
