Question

Distance between -6.2 and -9.1
Step By Step

Answer 1

`D=√(10)=3,16...`

Explanation:

`A(x_(1),y_(1))`

`B(x_(2);y_(2))`

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

`A(-6,2)`

`B(-9;1)`

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

`D=\sqrt{[-9-(-6)]^(2)+(1-2)^(2)}`

`D=\sqrt{[-9+6]^(2)+(1-2)^(2)}`

`D=\sqrt{[-3]^(2)+(-1)^(2)}`

`D=√(9+1)`

`D=√(10)=3,16...`

Answer 2

The distance between -6.2 and -9.1 is 2.9.

Explanation:

Given : Two numbers -6.2 and -9.1.

To find : What is the distance between the numbers ?

Solution :

Let A=-6.2

B=-9.1

The distance between two number is
`d=|B-A|`

Substitute the values,

`d=|-9.1-(-6.2)|`

`d=|-9.1+6.2|`

`d=|-2.9|`

`d=2.9`

Therefore, The distance between -6.2 and -9.1 is 2.9.
