use the imaginary number: \sqrt{-1} = i

\sqrt{-20}

\sqrt{(-1)*2*2*5}

2×i\sqrt{5}

2i\sqrt{5}

another example:

\sqrt{-4}

\sqrt{(-1)*2*2}

2 × i

2i

Find the distance from point A to the given line.
VMariaS [17]

Answer:

Let's see what to do buddy...

Step-by-step explanation:

_________________________________

Step (1)

To find the distance between the line which formed like :

ax + by + c = 0

and the point which is like :

h =  \binom{m}{n}  \\

we use following equation :

d =  \frac{ |a(m) + b(n) + c| }{ \sqrt{ {a}^{2} +  {b}^{2}  } } \\

_________________________________ Step (2)

y =  - x + 4

x + y - 4 = 0

So ;

a = 1

b = 1

c =  - 4

°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°

A = ( 2 , - 1 )

°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°

So we have :

d =  \frac{ | \: 1(2) + 1( - 1) - 4| }{ \sqrt{ {1}^{2} +  {1}^{2}  } } =  \\

d =  \frac{ |2 - 1 - 4| }{ \sqrt{1 + 1} } =  \frac{ | - 3| }{ \sqrt{2} }  \\

d =  \frac{3}{ \sqrt{2} } \\

_________________________________

And we're done.

Thanks for watching buddy good luck.

Will a circle always have a greater area than a square if the circumfrance and perimeter are the same
daser333 [38]
The answer is yes. here is how:
circumference of a circle is 2pi*r
perimeter of a square is 4a, a being the length of each side.
when 2pi*r=4a, r=(2a)/pi
area of the circle is pi*r^2=pi(2a/pi)^2=(4/pi)*a^2
area of the square is a^2
Because 4/pi is bigger than 1, (4/pi)*a^2 is always larger than a^2
