: 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
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
