Chapter P, Problem 14RE
Solution

a.

The distance between given two points.

  45

Given information:

Given points are 4,3, and 5,1 .

Formula used:

The distance between two pints, x1,y1, and x2,y2 , is given by:

  x2x12+y2y12

Calculation:

To calculate the distance between 4,3, and 5,1 , use the formula for the distance between two points x1,y1, and x2,y2 that is

  x2x12+y2y12

Here, points are 4,3, and 5,1 , thus the distance is calculated as:

  532+132=5+32+42=82+16=64+16=80=45

Thus, the distance between the given two points is 45 .

b.

The midpoint of the line with the given end points.

  12,1

Given information:

Given points are 4,3, and 5,1 .

Formula used:

The midpoint of a line segment with the end points x1,y1, and x2,y2 , is given by:

  x2+x12,y2+y12

Calculation:

To calculate midpoint of the line with the given end points, use the formula for the midpoint of line segment with endpoints x1,y1, and x2,y2 that is

  x2+x12,y2+y12

Here, points are 4,3, and 5,1 , thus the midpoint is calculated as:

  5+42,1+32=542,22=12,1

Thus, the midpoint of the line segment with given end points is 12,1 .
