Question
![The table presents projected future concentrations of a specific greenhouse gas in parts per billion (ppb), assuming current trends persist.
### Table of Gas Concentrations
| Year | 2010 | 2015 | 2020 | 2025 | 2030 |
|------|------|------|------|------|------|
| Gas (ppb) | 0.66 | 0.77 | 0.89 | 1.03 | 1.19 |
### Questions
#### a. Find Constants for the Growth Model
- Define \( x = 0 \) for the year 2010 and \( x = 20 \) for the year 2030.
- Determine constants \( C \) and \( a \) so that the equation \( f(x) = Ca^x \) accurately represents the data in the table.
\[
C = \_ \_
\]
\[
a \approx \_ \_ \_ \_ \_ \_
\]
(Round to the nearest hundredth.)
#### b. Estimate for 2023
- Calculate the estimated gas concentration for the year 2023.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fb8fa05ee-52b8-4b3d-a3d0-54c9685a9d54%2F4c5876ef-7deb-4149-ad07-4de117477f5e%2Fz5dbwoh_processed.png&w=3840&q=75)
