Question

Find the distance between the two points (2, -9) and (-1, 4) round to the nearest tenth .

Answer 1

Answer:

13.3 units (nearest tenth)

Step-by-step explanation:

$\boxed{Distance \: between \: 2 \: points = \sqrt{ {(x1 - x2)}^{2} + {(y1 - y2)}^{2} } }$

Using the formula above, distance

$= \sqrt{ {[2 - ( - 1)]}^{2} + ( - 9 - 4)^{2} }$

$= \sqrt{ {(2 + 1)}^{2} + ( - 13) {}^{2} }$

$= \sqrt{ {3}^{2} + ( - 13) {}^{2} }$

$= \sqrt{9 + 169}$

$= \sqrt{178}$

= 13.3 units (nearest tenth)
