Question

Determine the distance between the points (2, 5) and (7, 17)

Answer 1

vector = (7-2 , 17 -5 ) = (5, 12)

distance = sqrt( 5x5 + 12x12)

Answer 2

ans: 13

Answer 3

Use distance formula:
\[ d = \sqrt{(x_{2} - x_{1})^{2} + (y_{2} - y_{1})^{2}} \]

Plugging in those point values.

Answer 4

I suck at this / I know the formula but still not getting the answer

Answer 5

(7-2)^2 + (17-5)^2
(5)^2 + (12)^2
25 + 144
169

square root of 169 is 13, which is the distance between the points.

Answer 6

My attempt at showing how to plug the numbers in correctly. Maybe that would help in understanding what is going on...
