Understanding Hyperbola Shift

A hyperbola is a type of conic section that can be shifted horizontally and vertically. When a hyperbola is shifted, its center changes. In this article, we will explore how to calculate the new center of a hyperbola after it has been shifted to the right by 4 units and upward by 3 units.

Given Hyperbola Equation

The given hyperbola equation is:

\frac{(x-5)^2}{7}-\frac{(y+3)^2}{9}=1

This equation represents a hyperbola with a center at (5, -3).

Shifting the Hyperbola

To shift the hyperbola to the right by 4 units and upward by 3 units, we need to adjust the x and y coordinates of the center.

Shifting the Hyperbola to the Right

When shifting the hyperbola to the right by 4 units, the new x-coordinate of the center will be:

x_{new} = x_{old} + 4

Shifting the Hyperbola Upward

When shifting the hyperbola upward by 3 units, the new y-coordinate of the center will be:

y_{new} = y_{old} + 3

Calculating the New Center

Using the given hyperbola equation, we can calculate the new center of the hyperbola.

New x-Coordinate

The new x-coordinate of the center is:

x_{new} = 5 + 4 = 9

New y-Coordinate

The new y-coordinate of the center is:

y_{new} = -3 + 3 = 0

New Center of the Hyperbola

The new center of the hyperbola is (9, 0).

Conclusion

In this article, we have explored how to calculate the new center of a hyperbola after it has been shifted to the right by 4 units and upward by 3 units. We have used the given hyperbola equation to calculate the new x and y coordinates of the center. The new center of the hyperbola is (9, 0).

Key Takeaways

Hyperbola Shift and Center Calculation: Q&A =====================================

Frequently Asked Questions

In this article, we will answer some of the most frequently asked questions about hyperbola shift and center calculation.

Q: What is a hyperbola?

A: A hyperbola is a type of conic section that can be shifted horizontally and vertically. It is a set of points that are equidistant from two fixed points called foci.

Q: How do I calculate the new center of a hyperbola after it has been shifted?

A: To calculate the new center of a hyperbola after it has been shifted, you need to adjust the x and y coordinates of the original center. The new x-coordinate is calculated by adding the shift amount to the original x-coordinate, and the new y-coordinate is calculated by adding the shift amount to the original y-coordinate.

Q: What is the formula for calculating the new center of a hyperbola?

A: The formula for calculating the new center of a hyperbola is:

x_{new} = x_{old} + \Delta x

y_{new} = y_{old} + \Delta y

where $x_{old}$ and $y_{old}$ are the original x and y coordinates of the center, and $\Delta x$ and $\Delta y$ are the shift amounts.

Q: How do I determine the shift amounts?

A: The shift amounts are the amounts by which the hyperbola is shifted horizontally and vertically. For example, if the hyperbola is shifted to the right by 4 units and upward by 3 units, the shift amounts are $\Delta x = 4$ and $\Delta y = 3$ .

Q: Can I shift a hyperbola in any direction?

A: Yes, you can shift a hyperbola in any direction. However, the shift amounts must be specified in terms of the x and y coordinates of the center.

Q: How do I apply the shift amounts to the original center?

A: To apply the shift amounts to the original center, you simply add the shift amounts to the original x and y coordinates of the center.

Q: What is the new center of the hyperbola in the example given in the article?

A: The new center of the hyperbola is (9, 0).

Q: Can I use the same formula to calculate the new center of a hyperbola that has been rotated?

A: No, the formula for calculating the new center of a hyperbola that has been rotated is different from the formula for calculating the new center of a hyperbola that has been shifted. The formula for calculating the new center of a hyperbola that has been rotated is:

x_{new} = x_{old} \cos \theta - y_{old} \sin \theta

y_{new} = x_{old} \sin \theta + y_{old} \cos \theta

where $\theta$ is the angle of rotation.
