W ∝ L2 and W = 6 when L = 4. If L = √17 find W

A.

6(7/8)

B.

6(5/8)

C.

6(3/8)

D.

6(1/8)

Correct Answer: 6(3/8)

Explanation

W ∝ L2 W = KL2 K = W/L2 K = 6/42 K = 6/16 = 3/8 W = 3/8 L2 W = 3/8(√17)2 W = 3/8 x 17 W = 51/8 = 6(3/8

W ∝ L2 W = KL2 K = W/L2 K = 6/42 K = 6/16 = 3/8 W = 3/8 L2 W = 3/8(√17)2 W = 3/8 x 17 W = 51/8 = 6(3/8
