Question

Find the distance between each pair of points. Round to the nearest tenth if necessary​

Answer 1

Explanation:

1)

d² = (6-1)²+(3-1)²

or, d² = 5²+2²

or, d² = 25+4

so, d² = 29

so, d = 5.4 units

2)

d² = (4+2)²+(3-1)²

or, d² = 6²+2²

or, d² = 36 + 4

so, d² = 40

so, d = 6.3 units

3)

d² = (3-1)²+(-2-1)²

or, d² = 2²+(-3)²

or, d² = 4+9

or, d² = 13

so, d = 3.6 units

Answer 2

1) 5.4 2) 6.3 3) 3.6

Explanation:

Formula to find distance:
`d=\sqrt{(x2-x1)^(2) +(y2-y1)^(2) }`

1) coordinates = ( 1 , 1 ) , ( 6 , 3 )

distance = √(6-1)²+(3-1)²

= 5.4

2) coordinates = ( -2 , 1 ) , ( 4 , 3 )

distance = √(4--2)²+(3-1)²

= 6.3

3) coordinates = ( 1 , 1 ) , ( 3 , -2 )

distance = √(3-1)²+(-2-1)²

= 3.6
