Question

What is the length of the line segment with endpoints (10.8, – 5.3) and (-15.6, – 5.3) Enter your answer as a decimal in the box. units .

Answer 1

Answer: 26.4

Step-by-step explanation: (10.8, + 15.6, = 26.4

Answer 2

26.4

Step-by-step explanation:

The length of the segment that goes from (x1, y1) to (x2, y2) can be calculated as

`\sqrt[]{(x_2-x_1)^2+(y_2-y_1)^2}`

So, replacing (x1, y1) = (10.8, -5.3) and (x2, y2) = (-15.6, -5.3), we get:

`\begin{gathered} \sqrt[]{(-15.6-10.8)^2+(-5.3-(-5.3))^2} \\ \sqrt[]{(-26.4)^2+(-5.3+5.3)^2} \\ \sqrt[]{696.96+0^2} \\ \sqrt[]{696.96}=26.4 \end{gathered}`

Therefore, the answer is 26.4
