Find the constant of variation k in the case that y is direc

Find the constant of variation k in the case that y is directly proportional to x and inversely proportional to the squareroot of w, and y = 1/7 when x = 3 and w = 10 Answer: k = ______

Solution

Dear Student

Thank you for using CHegg

Given

y is directly proportional to x

y is inversely proportional to w^1/2

removing the sign f proportionality, we introduce a constant k

=>

y = kx/w^1/2

when x = 3, w=10 then y = 1/7

k = (1/7)*(10)^0.5 / 3

k = 0.150585 Solution
