The correct Answer is:
To find the vertices of the ellipse given by the equation \(\frac{x^2}{16} + \frac{y^2}{25} = 1\), we can follow these steps: ### Step 1: Identify the values of \(a^2\) and \(b^2\) The equation of the ellipse is in the standard form \(\frac{x^2}{a^2} + \frac{y^2}{b^2} = 1\). From the given equation, we can identify: - \(a^2 = 16\) - \(b^2 = 25\) ### Step 2: Calculate \(a\) and \(b\) Now, we take the square root of \(a^2\) and \(b^2\) to find \(a\) and \(b\): - \(a = \sqrt{16} = 4\) - \(b = \sqrt{25} = 5\) ### Step 3: Determine the orientation of the ellipse Since \(b > a\) (5 > 4), this indicates that the ellipse is vertically oriented. For a vertically oriented ellipse, the vertices are located at the points \((0, \pm b)\). ### Step 4: Find the coordinates of the vertices Using the value of \(b\): - The vertices are at \((0, +b)\) and \((0, -b)\). - Therefore, the vertices are \((0, 5)\) and \((0, -5)\). ### Final Answer The vertices of the ellipse \(\frac{x^2}{16} + \frac{y^2}{25} = 1\) are \((0, 5)\) and \((0, -5)\). ---
