The best that explains the relationship between t and W is d. the relationship is linear because W always decreases as values of t increases.
The relationship between t (months) and W (weight of the iceberg) is best described as linear.
The problem states that the iceberg loses 5 metric tons of weight each month. This means the weight decreases by a constant amount regardless of the current weight.
Complete Question:
An iceberg floating in the North Pacific Ocean weighs 80 metric tons. Each month it loses 5 metric tons of weight. Let W be the weight in metric tons of the iceberg after t months have passed. which of the following best explains the relationship between t and W ?
a. the relationship is exponential because W is multiplied by a factor of 30 each time increases by 1
b. the relationship is exponential because W is multiplied by a factor of 0.3 each time increases by 1
c. the relationship is exponential because W decreases by 5 each time t increases by 1.
d. the relationship is linear because W always decreases as values of t increases.
