Answer 1

To calculate the hot air balloon's elevation at each minute after takeoff, we can use the constant ascent rate of 400 feet per minute.

Here’s the calculation for each minute:

- At 0 minutes: 0 feet (initial elevation)
- At 1 minute: \(400 \text{ feet/minute} \times 1 \text{ minute} = 400\) feet
- At 2 minutes: \(400 \text{ feet/minute} \times 2 \text{ minutes} = 800\) feet
- At 3 minutes: \(400 \text{ feet/minute} \times 3 \text{ minutes} = 1200\) feet
- At 4 minutes: \(400 \text{ feet/minute} \times 4 \text{ minutes} = 1600\) feet

Now, we can complete the table:

| Minute | Elevation (feet) |
|--------|------------------|
| 0 | 0 |
| 1 | 400 |
| 2 | 800 |
| 3 | 1200 |
| 4 | 1600 |

This table shows the hot air balloon's elevation after each minute of ascent.
