Question

Please Find the distance between the two points rounding to the nearest tenth (if necessary).

(7,4) and (-2,9)

Answer 1

6.32455532034

Explanation:

Pythogreans theorem:

a^2 + b^2 = c^2 (we want c)

(9-7)^2+(-2-4)^2 = c^2

2^2 + (-6)^2 = c^2

4+36 = c^2

c = sqrt(40)

c = 6.32455532034

Answer 2

10.29 u

Explanation:

Given :-

• Two points (7,4) and (-2,9) is given to us.

And we need to find out the distance between the two points . So , here we can use the distance formula to find out the distance. As,

`:\implies` D = √{(x2-x1)² + (y2-y1)²}

`:\implies` D =√[ (7+2)² +(9-4)²]

`:\implies` D =√[ 9² +5²]

`:\implies` D =√[ 81 +25]

`:\implies` D = 10.29

Hence the distance between the two points is 10.29 units .
