Answer:
Step-by-step explanation:
x= -2
2x² - 5x + 6 = 2(-2)² - 5*(-2) + 6
= 2*4 + 10 + 6
= 8 + 10 + 6
= 24
Y = x/5280
converting miles to feet would be x=5280y
Answer:
4/7 as a decimal is 0.57142857142857.
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= 21
Thus the relationship is t = 21d
