Question 60781This question is from textbook
: Find the constant of variation k.
m varies directly with n; m = 144 when n = 8. This question is from textbook
You can put this solution on YOUR website! Given that m varies directly with n
That is m α n
m = kn (1)
Where k is the constant of variation.
Now substitute the values for m = 144 and n = 8, we get
144 = k*8
Divide the above equation by 8, we get
144/8 =k
18 = k
The constant of proportionality is 18.
