Distance Formula Flashcard

Front

What is the Distance Formula?

Back

The Distance Formula is used to determine the distance between two points in a coordinate plane. It is given by the formula: d = √((x2 - x1)² + (y2 - y1)²).

Front

How do you calculate the distance between the points (3, 4) and (7, 1)?

Back

Using the Distance Formula: d = √((7 - 3)² + (1 - 4)²) = √(16 + 9) = √25 = 5.

What is the significance of rounding in distance calculations?

Back

Rounding is important in distance calculations to provide a more manageable and understandable number, especially in real-world applications.

Front

If the distance between two points is 11.66, what does this represent?

Back

This represents the straight-line distance between the two points in the coordinate plane, rounded to the nearest hundredth.

Front

What units are commonly used when measuring distance?

Back

Common units for measuring distance include meters (m), kilometers (km), miles, and feet.

Front

How do you label distance in kilometers?

Back

When expressing distance in kilometers, you should include 'km' after the numerical value, e.g., 7.21 km.

Front

What is the distance between the points (1, 2) and (4, 6)?

Back

Using the Distance Formula: d = √((4 - 1)² + (6 - 2)²) = √(9 + 16) = √25 = 5.

Front

Why is it important to understand the Distance Formula?

Back

Understanding the Distance Formula is crucial for solving problems related to geometry, physics, and real-world applications involving distance.

Front

What is the first step in using the Distance Formula?

Back

The first step is to identify the coordinates of the two points you are measuring the distance between.

How do you find the distance between points in a three-dimensional space?

Back

In three-dimensional space, the Distance Formula is extended to d = √((x2 - x1)² + (y2 - y1)² + (z2 - z1)²).
