Question 1197996: 17. Using K as the constant, write an equation that expresses: The length (W) of a radio wave varies jointly as the square root of the inductance (L) and the capacitance (C).
A. W = kLC
B. W = √C/KL
C. W = k/√(LC)
D. W = k * LC
E. W = k * √(LC)
F. W = KL/√C

A. S = hk
B. S = h/k
C. S = k/h
D. h = k/S
E. k = h/S
F. k = hS

E. W = k * √(LC)
____
18. The weekly salary a woman earns (S) varies directly as the number of hours(h) she works
A. S = hk
___
19. V varies 'inversely with m. If v = 10, when m = 1/3, find v when m is 10.
Vm = 10*(1/3) = V*10
1/3 = V
___
20. N is 'inversely proportional to t + 3. if t = 1 when n = 3, find t when n = 2.
N(t+3) = 3*4 = 2*(t+3)
12-6 = 2t
3 = t
