Question 882405: A variable R is directly proportional to the square of P and inversely proportional to L, where P and L are other variable. Given that R= 2when P=2 and L=18, determine R when P=5 and L=50
Answer by richwmiller(17219) (Show Source): You can put this solution on YOUR website!
R=kP^2/L
2=k*2^2/18
36=4k
k=9
R=9*P^2/L
R=9*25/50
R=4.5
