Solution
Solution Steps
To find the assets for the given years, we need to substitute the corresponding value of \( x \) into the function \( A(x) = 330 e^{0.056x} \). The value of \( x \) is determined by the number of years since 2007. For example, for 2011, \( x = 4 \) because 2011 is 4 years after 2007. Similarly, calculate \( x \) for 2014 and 2017, and then evaluate the function for each year.
Step 1: Calculate Assets for 2011
To find the assets in 2011, we substitute \( x = 4 \) into the function \( A(x) = 330 e^{0.056x} \):
\[
A(4) = 330 e^{0.056 \cdot 4} \approx 412.9
\]
Thus, the assets in 2011 are approximately \$412.9 billion.
Step 2: Calculate Assets for 2014
Next, for 2014, we substitute \( x = 7 \) into the same function:
\[
A(7) = 330 e^{0.056 \cdot 7} \approx 488.4
\]
Therefore, the assets in 2014 are approximately \$488.4 billion.
Step 3: Calculate Assets for 2017
Finally, for 2017, we substitute \( x = 10 \):
\[
A(10) = 330 e^{0.056 \cdot 10} \approx 577.7
\]
Consequently, the assets in 2017 are approximately \$577.7 billion.
