Question
### An equation of an ellipse is given.

\[
\frac{x^2}{25} + \frac{y^2}{16} = 1
\]

#### (a) Find the vertices, foci, and eccentricity of the ellipse.

- **Vertex**
  - \((x, y) = \Bigg( \underline{\hspace{1cm}} , \underline{\hspace{1cm}} \Bigg)\) (smaller x-value)
  - \((x, y) = \Bigg( \underline{\hspace{1cm}} , \underline{\hspace{1cm}} \Bigg)\) (larger x-value)

- **Focus**
  - \((x, y) = \Bigg( \underline{\hspace{1cm}} , \underline{\hspace{1cm}} \Bigg)\) (smaller x-value)
  - \((x, y) = \Bigg( \underline{\hspace{1cm}} , \underline{\hspace{1cm}} \Bigg)\) (larger x-value)

- **Eccentricity**
  - \(\underline{\hspace{2cm}}\)

#### (b) Determine the length of the major axis.
- \(\underline{\hspace{5cm}}\)

#### Determine the length of the minor axis.
- \(\underline{\hspace{5cm}}\)

#### (c) Sketch a graph of the ellipse.
- *Explain or draw the graph of the ellipse based on the given equation.*
