Answer:

see below

Step-by-step explanation:

i.

= √(3 + 4i)

= 2 + i

ii.

= √(-8 + 6i)

= √2(-4 + 3i)

iii.

= √(-40 - 42i)

= √-2(20 + 21i)

iv.

= √i

= √i

v.

= \sqrt{\frac{2 + 3i}{5 - 4i} } +\sqrt{\frac{2-3i}{5+4i} }

= \sqrt{\frac{-2+23i}{41} } +\sqrt{\frac{2-3i}{46} }

Convert 10pi/9 to degree measure.
MrRissso [65]

Answer:

The answer is

<h2>200°</h2>

Step-by-step explanation:

To convert an angle from degrees to radians multiply the value by \frac{180}{\pi}

From the question the value to be converted is \frac{10\pi}{9}

Converting it into degrees we have

\frac{10\pi}{9}  \times  \frac{180}{\pi}  \\  =  \frac{1800}{9}

We have the final answer as

<h3>200°</h3>

Hope this helps you

Determine whether the given lengths can be sides of a right triangle. Explain. 10 in., 24 in., 26 in.
notsponge [240]
10 in, 24 in, and 26 in. By the Converse of the Pythagorean Theorem, the lengths must satisfy the equation c² = a² + b². Let 26 = hypotenuse and 10 and 24 the legs of the triangle.
26² = 10² + 24²
676 = 100 + 576
676 = 676.
Yes, they can be lengths of a right triangle.
