To determine which situation could describe the graph, we need to analyze the scenarios:

  1. Sienna buys a vintage record for $20. Its value appreciates by 20 percent each year.

    • This is an example of exponential growth (specifically, a percentage increase of the current value). The value can be modeled as \( V(t) = 20 \times (1.2)^t \).
  2. There are 200 cockroaches in a building, and the population triples every day.

    • This is also an example of exponential growth, with a model of \( P(t) = 200 \times (3)^t \), where \( t \) is in days.
  3. Niall rents a bike for $20 per hour.

    • This situation represents a linear relationship, where the cost increases linearly with time. The model would be \( C(t) = 20t \), where \( t \) is in hours.
  4. Juveldy puts $20 in a high-yield savings account. His investment triples every year.

    • This is another example of exponential growth and can be modeled as \( I(t) = 20 \times (3)^t \).

The first, second, and fourth options represent exponential growth, while the third represents linear growth. Without seeing the specific graph, we can conclude that:

  • If the graph depicts exponential growth, it could represent any of the first, second, or fourth situations.
  • If it depicts linear growth, then it would correspond to the third situation.

So, depending on the nature of the graph, options 1, 2, and 4 depict exponential growth, while option 3 represents a linear relationship. If you provide the graph characteristics, I can help identify the most likely match.

A local bakery opened with new equipment worth $80,000. Ten years later, the owners’ accountants told them that their equipment had depreciated at a rate of 6 percent per year. Which equation would you use to create a sequence modeling this situation?(1 point)
Responses

an=80,000(0.06)n
a subscript n baseline equals 80,000 left parenthesis 0.06 right parenthesis superscript n baseline

an=80,000(0.06)n−1
a subscript n baseline equals 80,000 left parenthesis 0.06 right parenthesis superscript n minus 1 baseline

an=80,000(0.94)n
a subscript n baseline equals 80,000 left parenthesis 0.94 right parenthesis superscript n baseline

an=80,000(0.94)n−1

The correct equation to model the depreciation of the equipment is:

\( a_n = 80,000(0.94)^n \)

This equation reflects a yearly depreciation of 6%, which means the value of the equipment retains 94% (100% - 6%) of its value each year.

In a certain geographic location, a herd of elephants is declining at a rate of four percent every year. If there are currently 62 elephants in the herd, create an exponential decay function to model the problem. Let y represent the number of elephants after t years.(1 point)
Responses

y=62(1.04)t
y equals 62 left parenthesis 1.04 right parenthesis superscript t baseline

y=62(0.6)t
y equals 62 left parenthesis 0.6 right parenthesis superscript t baseline

y=62(0.04)t
y equals 62 left parenthesis 0.04 right parenthesis superscript t baseline

y=62(0.96)t

The correct exponential decay function to model the decline of the elephant herd is:

\( y = 62(0.96)^t \)

This reflects a decline of 4% per year, meaning the herd retains 96% of its population each year (100% - 4% = 96%).
