 Question 163535This question is from textbook college algebra : can somebody help me solve this problem: if w varies directly with A and Inversely with I, if A = 4 when I=2 and w=2, what is the constant of variation, K? this is what i tried... 2=k/2, so k is 4, is this the constant of variation? This question is from textbook college algebra Answer by ankor@dixie-net.com(15625)   (Show Source): You can put this solution on YOUR website!can somebody help me solve this problem: if w varies directly with A and Inversely with I, if A = 4 when I=2 and w=2, what is the constant of variation, K? this is what i tried... 2=k/2, so k is 4, is this the constant of variation? : Write the equation as given w = : Substitute for A, I and w 2 = Two cancels into 4 so you have: 2 = 2K K = K = 1: is the constant of variation : Giving us: w = : It's obvious if A=4, and I = 2, w = 2 ; : did this help?
