Taro uses a coordinate systemwith units of feet to keep frack of the locations of any objects he finds with his metal detector. One lucky day he found a ring at (5,7) and an old coin at (10,19). How far apart were the ring and coin before taro found them? Round them to the nearest tenth if necessary.

The distance between ring and coin is 13 units apart.

Step-by-step explanation:

Using this formula, you are able to find the distance between the ring and the old coin :

Let (x1,y1) be (10,19),

Let (x2,y2) be (5,7),

D = √(10-5)²+(19-7)²

= √5²+12²

= √25+144

= √169

= 13 units

answer: the common difference is -0.10

i think 1: 2
