The force exerted on a spring is proportional to the distance the spring is stretched from its relaxed position. Suppose you stretch a spring a distance of d inches by applying a force of F pounds. For your spring, d/F = 0.8. You apply forces between 40 lb and 54 lb, inclusive. What inequality describes the distances the spring is stretched?

Question

The force exerted on a spring is proportional to the distance the spring is stretched from its relaxed position. Suppose you stretch a spring a distance of d inches by applying a force of F pounds. For your spring, d/F = 0.8. You apply forces between 40 lb and 54 lb, inclusive. What inequality describes the distances the spring is stretched? a. 32 ≤ d ≤43.2 b. 40 < d < 54** c. d < 32 or d > 43.2 d. d < 40 or d > 54

The right answer is A I just took the quiz and got 100% right answers are: A B B C D A Just took it!

oobleck · Answer

clearly not B. That describes the force applied. You want the distances.

anonymous · Answer

then its d

oobleck · Answer

It cannot be D. You have a range of forces, which will produce a range of distances. Stop guessing. d/F = 0.8 d = 0.8F 40 <= F <= 54 0.8*40 <= 0.8F <= 0.8*54 32 <= d <= 43.2
