What is the approximate distance from the origin to the point (−5, 6, −1)? round to the nearest tenth. 3.2 units 3.5 units 7.7 units 7.9 units

 The correct option is (D) 7.9 units.

Step-by-step explanation:  We are given to find the approximate distance from the origin to the point (−5, 6, −1).

We know that

the distance between the points (a, b, c) and (d, e, f) is given by

Therefore, the distance between the origin (0, 0, 0) and the point (-5, 6, -1) is given by

Rounding to the nearest tenth, we get

D= 7.9 units.

Thus, the required distance is 7.9 units.

Option (D) is CORRECT.
