Question

Find the distance AB between the points A (8, 2) and B(3,9). Round your answer to the nearest

tenth, if necessary.

Answer 1

d = 8.6

d = √74

Explanation:

`A (8, 2) = (x_1 ,y_1)\\ B(3,9) = (x_2,y_2)\\\\d = √(\left(x_2-x_1\right)^2+\left(y_2-y_1\right)^2)\\\\d =√(\left(3-8\right)^2+\left(9-2\right)^2)\\\\d=√((5)^2+(7)^2)\\\\d=√(25+49)\\\\d=√(74)\\\\d = 8.6023\\\\d = 8.6`
