Chapter 7: Problem 70

Describe how to graph \(\frac{x^{2}}{25}+\frac{y^{2}}{16}=1\)

Short Answer

Expert verified
The ellipse graph will be centered at (0,0) with a semi-major axis length of 5 units along the x-axis and a semi-minor axis length of 4 units along the y-axis.

Step by step solution

01

Identify the Center

For the ellipse with the equation \(\frac{x^{2}}{a^{2}}+\frac{y^{2}}{b^{2}}=1\), the center will always be at the origin (0,0) because there are no terms that subtract or add to \(x\) and \(y\). So, mark the point (0,0) on your graph as the center of the ellipse.
02

Draw the Axes of the Ellipse

The length of the semi-major axis is given by the constant under \(x^{2}\) and the length of the semi-minor axis is given by the constant under \(y^{2}\). Draw a horizontal line passing through the center (0, 0) of the ellipse spanning from -5 to 5 along the x-axis and a vertical line also passing through the center of the ellipse spanning from -4 to 4 along the y-axis, using these axes lengths.
03

Draw the Ellipse

Knowing the center of the ellipse and axes, you can now draw the ellipse. Keep your curve within the boundaries defined by the semi-major and semi-minor axes and make sure it encompasses the entire x and y span from -5 to 5 and -4 to 4 respectively.

Consult the research department of your library or the Internet to find an example of architecture that incorporates one or more conic sections in its design. Share this example with other group members. Explain precisely how conic sections are used. Do conic sections enhance the appeal of the architecture? In what ways?

Find the solution set for each system by graphing both of the system's equations in the same rectangular coordinate system and finding points of intersection. Check all solutions in both equations. $$\left\\{\begin{array}{c}4 x^{2}+y^{2}=4 \\\x+y=3\end{array}\right.$$

Write an equation for the path of each of the following elliptical orbits. Then use a graphing utility to graph the two cllipses in the same viewing rectangle. Can you see why early astronomers had difficulty detecting that these orbits are ellipses rather than circles? \(\cdot\) Earth's orbit: Length of major axis: 186 million miles Length of minor axis: 185.8 million miles \(\cdot\) Mars's orbit: Length of major axis: 283.5 million miles Length of minor axis: 278.5 million miles

Find the solution set for each system by graphing both of the system's equations in the same rectangular coordinate system and finding points of intersection. Check all solutions in both equations. $$ \left\\{\begin{array}{c} (y-3)^{2}=x-2 \\ x+y=5 \end{array}\right. $$

Find the solution set for each system by graphing both of the system's equations in the same rectangular coordinate system and finding points of intersection. Check all solutions in both equations. $$ \left\\{\begin{array}{r} (y-2)^{2}=x+4 \\ y=-\frac{1}{2} x \end{array}\right. $$
