Question #89d37

Answer 1

`sqrt5~~2.236" to 3 dec. places"`

Explanation:

`"to calculate the distance (d) use the "color(blue)"distance formula"`

`color(red)(bar(ul(|color(white)(2/2)color(black)(d=sqrt((x_2-x_1)^2+(y_2-y_1)^2))color(white)(2/2)|)))`
where `(x_1,y_1),(x_2,y_2)" are 2 coordinate points"`

`"the 2 points are " (x_1,y_1)=(3,-2),(x_2,y_2)=(2,-4)`

`d=sqrt((2-3)^2+(-4+2)^2)=sqrt(1+4)=sqrt5~~2.236`
