Answer:

$\sqrt{80}$

80 is the number in the square root

Step-by-step explanation:

$d = \sqrt{(x_{2}-x_{1} )^{2} +(y_{2}-y_{1} )^{2} } \\d = \sqrt{(4-(-4) )^{2} +(5- 1 )^{2} }\\d = \sqrt{(4+4 )^{2} +4^{2}\\d = \sqrt{8^{2} +4^{2} }\\d=\sqrt{64 +16}\\d=\sqrt{80}$

What is the midpoint of a segment in the complex plane with endpoints at 3 – 2i and 17 – 8i?

chubhunter [2.5K]

In the complex plane, the two given points are represented by $(3,-2)$ and $(17,-8)$ . The midpoint would then be

$\left(\dfrac{3+17}2,\dfrac{-2+(-8)}2\right)=(10,-5)$

which represents the complex number $10-5i$ .
