Find the distance between C(-5,4) and Q(2,0)
anastassius [24]

9514 1404 393

Answer:

  √65 ≈ 8.06

Step-by-step explanation:

The distance formula is used for the purpose.

  d = √((x2 -x1)² +(y2 -y1)²)

  d = √((2 -(-5))² +(0 -4)²) = √(7² +(-4)²) = √(49 +16)

  d = √65 ≈ 8.0622577

The distance between C and Q is √65, about 8.06 units.
