Question

Find the distance between the two points. Round to the nearest tenth if necessary. (10, –8), (4, 0) a. 2 b. 10 c. 16 d. 100

Answer 1

D = sqrt (x2 - x1)^2 + (y2 - y1)^2
(10,-8)...x1 = 10 and y1 = -8
(4,0)...x2 = 4 and y2 = 0
now sub and solve
d = sqrt (4 - 10)^2 + (0 -(-8)^2
d = sqrt (-6^2) + (8^2)
d = sqrt (36 + 64)
d = sqrt 100
d = 10 <==
