On a map, a hospital is located at (-42,7). A wreck occurs at (13,-14). How far must the Air Care helicopter fly to reach the wreck from the hospital. (Each unit on the map equals one mile.)

The helicopter must cover a straight line distance of approximately 61.270 miles from the hospital to the wreck site.

Step-by-step explanation:

Let suppose that Air Care helicopter travels in straight line from the hospital to the wreck site, we can determine that distance (), measured in miles, by using the following Pythagorean identity from Analytical Geometry:

Where:

, - Location of the wreck site, measured in miles.

, - Location of the hospital, measured in miles.

If the location of the wreck site and the hospital are and , respectively. The distance that helicopter must cover is:

The helicopter must cover a straight line distance of approximately 61.270 miles from the hospital to the wreck site.

step-by-step explanation:

84/3.5 = 24

answer: the distance

step-by-step explanation:

to calculate the distance d of a line segment with endpoints (x1, y1) and (x2, y2) use the formula d (x2 x1)2 (y2 y1)2. to calculate the midpoint of a line segment with endpoints (x1, y1) and (x2, y2) use the formula
