Question

Which statement is true about the formula, \(d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}\) when describing the distance along a line segment?

- A) It is not a precise definition because it uses variables to represent unknown values.
- B) It is not a precise definition because it uses a square root sign, which means the result might be an irrational number.
- C) It is not a precise definition because it is based on an understanding of points, which is an undefined term.
- D) It is not a precise definition because it is based on an understanding of coordinates, which are defined based on the distance of a line segment.

Answer 1

C. Distance is a scalar and has no direction, while displacement is a vector and has a direction.

Step-by-step explanation:

The statement that is true about the formula, d = √((x2 - x1)^2 + (y2 - y1)^2), when describing the distance along a line segment is:

C. It explains that distance is a scalar and it has no direction attached to it, whereas displacement is a vector and direction is important.

d. It explains that both distance and displacement are scalar and no directions are attached to them
