Chapter 1: Q. 43 (page 15)

Find the distance $d (P_{1}, P_{2})$ between the points $P_{1} and P_{2}$ .
$P_{1} = (a, b); P_{2} = (0, 0)$

Short Answer

Expert verified

The distance between the points is $d = \sqrt{a^{2} + b^{2}}$ .

Step by step solution

Step 1. Given information.

Find the distance between the points.

$P_{1} = (a, b); P_{2} = (0, 0)$

Step 2. Substitute the values in the formula.

The length of the line segment is the distance between the points $P_{1} = (x_{1}, y_{1}) = (a, b) and P_{2} = (x_{2}, y_{2}) = (0, 0)$ . Using the distance formula with $x_{1} = a, y_{1} = b, x_{2} = 0, and y_{2} = 0$ the length d is

$d = \sqrt{{(x_{2} - x_{1})}^{2} + {(y_{2} - y_{2})}^{2}} d = \sqrt{{(0 - a)}^{2} + {(0 - b)}^{2}} d = \sqrt{a^{2} + b^{2}}$

Step 3. Conclusion.

The distance between the points is $\sqrt{a^{2} + b^{2}}$ .
