What is √-11 in the form a+bi?

Mice21 [21]

Given:

The number is $\sqrt{-11}$ .

To find:

The a+bi form of given number.

Solution:

We have,

$\sqrt{-11}$

It can be written as

$\sqrt{-11}=\sqrt{-1\times 11}$

$\sqrt{-11}=\sqrt{-1}\times \sqrt{11}$ $[\because \sqrt{ab}=\sqrt{a}\sqrt{b}]$

$\sqrt{-11}=i\times \sqrt{11}$ $[\because \sqrt{-1}=i]$

$\sqrt{-11}=\sqrt{11}i$

Here, real part is missing. So, it can be taken as 0.

$\sqrt{-11}=0+\sqrt{11}i$

So, a = 0 and $b=\sqrt{11}$ .

Therefore, the a+bi form of given number is $0+\sqrt{11}i$ .

Find the area of the shape shown below. 12 5 5 units

Yanka [14]

Answer:

42.5 units²

Explenation:

The area of the square on the left is 5×5=25.

At the top you do 12-5=7 to find the length of the tringle.

Than it is 7×5=35 than this divided by two, so 17.5.

You add both areas 25+17.5=42.5

The slope is 6 and it passes through (-4,4)

Rasek [7]

Answer:

y=6x+28

Step-by-step explanation:

To write the equation of a line, you need a slope and a point substituted into the point slope form $y-y_1=m(x-x_1)$ .

m= 6 and (-4,4) will be substituted into the equation above.

$y-4=6(x--4)\\y-4=6(x+4)\\y-4=6x+24\\y=6x+28$
