Question

which of the contexts below represents linear growth? answer an elevator descends at a rate of 26 feet per second. a coin collection appreciates at a rate of 3.3% per year. the amount of a certain medication in a persons bloodstream decreases by \\(\frac{1}{4}\\) every hour. victoria puts $30 a month into a savings account.

Explanation:

Linear growth is characterized by a constant absolute change in quantity over equal time intervals, not a relative (percentage/fractional) change.

1. The elevator shows constant decrease (not growth) at a fixed rate.
2. The medication shows a fractional decrease, not growth, and the change is relative.
3. The coin collection appreciates by a percentage, which is exponential (relative) growth, not linear.
4. Adding a fixed $30 each month is a constant absolute increase over equal time periods, fitting linear growth.

Answer:

Victoria puts $30 a month into a savings account.
