yarga [219]

Answer:

t = 21d

Step-by-step explanation:

Here tension and distance are denoted t by d and respectively. Since t varies directly with d , then the relation between t and d is k=td Given that, for the tension 42 pounds, the spring is stretched 2 inches. Substituting t = 42 and d= 2 into t = kd find the value of k . Therefore,

42= K (2)

$K=\frac{42}{2}$

K= 21

Thus the relationship is t = 21d
