Answer:

\sqrt{-245}  in the form a + bi is 0+7\sqrt{5}i

Step-by-step explanation:

We know that

       i=\sqrt{-1}

We need to find  \sqrt{-245}

     \sqrt{-245}=\sqrt{-1}\times \sqrt{245}=i\sqrt{245}=i\sqrt{49\times 5}=i\times 7\sqrt{5}

\sqrt{-245}  in the form a + bi is 0+7\sqrt{5}i

Answer: First option.

Step-by-step explanation:

It is important to remember the definition of  "Translation".

A Translation is defined as a transformation that moves every point of an object a determine   distance in a given direction. In Translation, the shape and the size of the object do not change.

Then, given a point:

 (x,y)

Where "x" is the x-coordinate and "y" is the y-coordinate.

And given the following translation:

(x+2,y-4)

We can notice that:

  • 2 units are added to  the original x-coordinate. This indicates that  the object must be moved 2 units to the right.
  • 4 units are subtract from the original y-coordinate. This indicates that  object must be moved 4 units down.
