Answer:

7.0711

= 7.1 (rounded to nearest tenth)

Step-by-step explanation:

see attached.

Answer 2

For this case we have by definition, that the distance between two points is given by:

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

According to the given data, we have the following points:$(x_ {1}, y_ {1}) = (6, -5)\\(x_ {2}, y_ {2}) = (- 1, -4)$

Substituting the points in the formula we have:

$d = \sqrt {(- 1-6) ^ 2 + (- 4 - (- 5)) ^ 2}\\d = \sqrt {(- 7) ^ 2 + (- 4 + 5) ^ 2}\\d = \sqrt {(- 7) ^ 2 + (1) ^ 2}\\d = \sqrt {49 + 1}\\d = \sqrt {50}\\d = 7.0711$

Rounding off we have to:

$d = 7.1$

ANswer:

$d = 7.1$
