z varies directly as x^2 and inversely as y^2 If z = 108 when x = 6 and y = 7, find z if x = 8 and y = 2. (Round off your answer to the nearest hundredth.)
英语翻译Express the statement as a formula that involves the variables w,z,u and a constant of proportionality k,and then determine the value of k from the condition :w varies directly as z and inversely as the square root of u,if z = 6 and u = 4,then w = 24Please enter your ans...
For example, if a varies inversely with b, then it can be expressed as aα1b or a=kb where k is the constant of variation. Answer and Explanation: Since y varies directly with x, yαx, or we can write it as y=kx where k is the constant of variation....
