A beam in a viewing booth for officials at the Daytona 500 auto race is being replaced. The strength(weight) of a beam (s) is directly proportional to its width (w) and the square of its depth (d).
Write an equation for s involving the width and the depth that could be used to solve for the constant of variation k.
s=k*w*d^2
The current beam is 3.5 inches wide and 6 inches deep and will support a weight of 1260 pounds. Find the constant of variation k.
1260=k*3.5*6^2
1260=k*126
k=1260/126
k=10
If a replacement beam is 3 inches wide and 7 inches deep, how much weight can it suppo

Best ResponseYou've already chosen the best response.0Aby what is the trouble here.You have found out everything.you know k,the equation relating depth ,length and weight.Substitute corresponding values.i.e here find s. Yopu know s=10*w*d^2 So weight supported =s=10*3*7^2
