<h3>LENGTH</h3>

================================

\large \sf \underline{Answer:}

\qquad\qquad \qquad \huge  \bold{\sqrt{74} }

================================

\large \sf \underline{Solution:}

Solving;

  • \sf{D=\sqrt{(7-2)^2+(1-(-6))^2}}

  • \sf{D=\sqrt{5^2+7^2}}

  • \sf{D=\sqrt{25+49}}

  • \sf \underline {\pmb{D=\sqrt{74}}}

Hence, the length of segment AB is √74.

Answer:

\sqrt{74}

Step-by-step explanation:

<u>Distance between two points</u>

d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

\textsf{let}\:(x_1,y_1)=(2,-6)

\textsf{let}\:(x_2,y_2)=(7,1)

d=\textsf{length of segment AB}

Substituting points into the distance formula and solving for d:

\implies d=\sqrt{(7-2)^2+(1-(-6))^2}

\implies d=\sqrt{5^2+7^2}

\implies d=\sqrt{25+49}

\implies d=\sqrt{74}

Multiply (9 − 4i)(2 + 5i).
lara [203]

Answer:

38 + 37i

Step-by-step explanation:

(9 − 4i)(2 + 5i)

FOIL

first: 9*2 = 18

Outer: 9*5i = 45i

inner: -4i * 2 = -8i

last : -4i * 5i = -20i^2 = -20(-1) = 20

Combine together

18+45i-8i +20

38 + 37i
