Question

What is the distance between points H(7,10) and X(5, -8)? Round the answer to the nearest tenth.

Answer 1

Step-by-step explanation:

Using the distance formula:

$d = \sqrt{(x2 - x1) ^{2} + (y2 - y1)^{2} }$

point H and point X are the two we need to find the distance of, so

x1 = 7, y1 = 10

x2 = 5, y2 = -8

Now,

$d \: = \sqrt{(5 - 7) ^{2} + {( - 8 - 10)}^{2} } \\ = \sqrt{ { (- 2)}^{2} + ( - 18) ^{2} } \\ = \sqrt{4 + 324} \\ = \sqrt{328} \\ = 18.11$

~ approximately 18 to the nearest round of.

Answer: 18
