Question

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.

Answer 1

The distance between ring and coin is 13 units apart.

Explanation:

`\sqrt{ {(x1 - x2)}^(2) + {(y1 - y2)}^(2) }`

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 2

Answer: 13 units

Explanation:

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
