Does it look like this: \frac{ \sqrt{-4} }{(3+i)-(2+3i)} =  \frac{-2i}{1-2i} or \frac{2i}{2i-1}

Do you need the others?

Answer:

\frac{-4+2i}{5}  

Step-by-step explanation:

\frac{\sqrt{-4}}{(3+i)-(2+3i)}

simplify the denominator

\frac{\sqrt{-4}}{1-2i}

square root (-4) is +2i , because the value of square root (-1) is 'i'

\frac{+2i}{1-2i}                    

multiply top and bottom by its conjugate 1+2i

\frac{2i(1+2i)}{(1-2i)(1+2i)}  

\frac{2i+4i^2}{1+2i-2i-4i^2}  

The value of i^2 =-1

\frac{2i+4(-1)}{1+2i-2i-4(-1)}  

\frac{2i-4}{5}  

\frac{-4+2i}{5}

I got an answer but im really not sure if its right so please help
Vladimir79 [104]

Answer:

60 degrees.

Step-by-step explanation:

Since you know that y = 74 because they are vertical angles, and 46 = the angle across from it (there is a theorem for it). Since one line is 180 degrees, and you already know the two sides next to x, which is 74 and 46, you can do 180 - 74 - 46. Your final answer should be 60 degrees.

Travka [436]
Volume of a volleyball (a sphere) = 4/3πr³
= 4/3π(11.4)³
= 1975.392π
= 6210 cm³ (to 3 significant figures)

The volume of a volleyball with a radius of 11.4 cm will be 6210 cm³.
