Exam 1

  1. Question

    What is the distance between the two points p=(2,4) and q=(5,5) in a Cartesian coordinate system?

    1. 1.261
    2. 2.000
    3. 2.695
    4. 0.408
    5. 3.162

    Solution

    The distance d of p and q is given by d2 =( p1 - q1 )2 +( p2 - q2 )2 (Pythagorean formula).
    Hence d=( p1 - q1 )2 +( p2 - q2 )2 =(2-5 )2 +(4-5 )2 =3.162.
