Question

Check my answer?? Find the distance between the points A(10, –9) and B(8, 7). Round your answer to the nearest hundredth.

A.5.09
B.10.63
C.15.00
D.16.12

Answer 1

Thedistance formula is derived from the Pythagorean theorem. It is expressed as:

d = √(x2-x1)^2 + (y2-y1)^2

d = √(8-(10))^2 + (7-(-9))^2
d = 2√65 = 16.124

Therefore, the correct answer from the choices is option D.
