Find the distance between point C (-7,5) and D (8,16) round to the nearest tenth.

1 answer

To find the distance between two points in a coordinate plane, we can use the distance formula:
√((x2 - x1)² + (y2 - y1)²)

Let's label the coordinates:
C(x1, y1) = (-7,5)
D(x2, y2) = (8,16)

Plugging in the values, we get:
√((8 - (-7))² + (16 - 5)²)
= √((8 + 7)² + (16 - 5)²)
= √(15² + 11²)
= √(225 + 121)
= √346
≈ 18.6

Therefore, the distance between point C (-7,5) and D (8,16) rounded to the nearest tenth is approximately 18.6.
