Question

15 points if help!! Find the distance CD rounded to the nearest tenth.

Answer 1

10.77

Explanation:

(-5, 4) (5, 8) Find the difference between the x terms: that is[( 5-(-5)]

Find the difference between the y terms: that is (8 - 4)

Substitute into the distance formula

(
`\sqrt{[(5 - (-5)]^(2) + (8 - 4)^(2) } }`

=
`\sqrt{10^(2) +4^(2) }`

=
`√(100 + 16)`

=
`√(116)`

= 10.77
