Question

Find the distance between a(-3,-7) and c(-5,8).Round to the nearest tenth.

Answer 1

distance = 15.1

Explanation:

To find the distance between two points, we can use a formula called the distance formula.

The distance formula is
`d=√((x_2-x_1)^2+(y_2-y_1)^2)` where
`x_1,y_1` are the coordinates of the first point and
`x_2,y_2` are the coordinates of the second point.

Points: (-3, -7) (-5, 8)

`d=√((-5-(-3))^2+(8-(-7))^2)`

`d=√((-2)^2+(15)^2)`

`d=√(4+225)`

`d=√(229)`

The distance between (-3, -7) and (-5, 8) is
`√(229)` or 15.13

15.13 rounded to the nearest tenth is 15.1
