Math Problem Statement

Find the length of each segment. The segments PQ, RS, and TV have the following endpoints: P(-6, 3), Q(-4, 0), R(-3, -4), S(0, -2), T(4, 2), V(5, -2).

Solution

To solve the problem, we need to find the length of each segment using the distance formula. The distance formula between two points (x1,y1)(x_1, y_1) and (x2,y2)(x_2, y_2) is:

d=(x2x1)2+(y2y1)2d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}

Let's calculate the lengths of the segments PQPQ, RSRS, and TVTV.

  1. For PQPQ, with endpoints P(6,3)P(-6, 3) and Q(4,0)Q(-4, 0):

PQ=((4)(6))2+(03)2=(2)2+(3)2=4+9=13PQ = \sqrt{((-4) - (-6))^2 + (0 - 3)^2} = \sqrt{(2)^2 + (-3)^2} = \sqrt{4 + 9} = \sqrt{13}

  1. For RSRS, with endpoints R(3,4)R(-3, -4) and S(0,2)S(0, -2):

RS=(0(3))2+(2(4))2=(3)2+(2)2=9+4=13RS = \sqrt{(0 - (-3))^2 + (-2 - (-4))^2} = \sqrt{(3)^2 + (2)^2} = \sqrt{9 + 4} = \sqrt{13}

  1. For TVTV, with endpoints T(4,2)T(4, 2) and V(5,2)V(5, -2):

TV=(54)2+(22)2=(1)2+(4)2=1+16=17TV = \sqrt{(5 - 4)^2 + (-2 - 2)^2} = \sqrt{(1)^2 + (-4)^2} = \sqrt{1 + 16} = \sqrt{17}

Answers:

  • PQ=13PQ = \sqrt{13}
  • RS=13RS = \sqrt{13}
  • TV=17TV = \sqrt{17}
