Question

Find the distance between 4 (7,-7) and B (13,0). Write your answer as a radical and as a decimal rounded to the nearest tenth.

The distance between the two points is_____,
or about_____.

Answer 1

Distance is
`√(85)` or 9.2195...

Hope this helps!

Explanation:

d =
`\sqrt{(x_(2)-x_(1) )^(2) + (y_(2) - y_(1) )^(2) }`

d =
`\sqrt{(13 - 7 )^(2) + (0-(-7)^(2) }`

d =
`\sqrt{(6)^(2) +(7)^(2) }`

d =
`√(36 + 49)`

d =
`√(85)`

d = 9.2195444...
