Question

What is the distance from the point (−3, −b, c) to the origin?

Answer 1

Answer:

A

Step-by-step explanation:

Answer 2

Answer:

  $\sqrt{9+b^2+c^2}\,\text{units}$

Step-by-step explanation:

The distance formula tells you the distance d between the points (0, 0, 0) and (-3, -b, c) is ...

  d = √((x2 -x1)² +(y2 -y1)² +(z2 -z1)²) = √((-3-0)² +(-b-0)² +(c-0)²)

  = √(9 +b² +c²)
