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.

Two boats on opposite banks of a river start moving towards each other. They first pass each other 1400 meters from one bank. Th
Nesterboy [21]

S1 = speed of boat 1

<span> t1 =  time to do 1400 meters (boat 1) </span>

S1*t1 = 1400

<span><span>S2  </span>= speed of boat 2 </span>

1400 + S2*t1 = X

t2 = time to do X + 600 (boat 2)

S1*t2 = X + 600

S2*t2 = 2X - 600

S1 = 1400/t1

S2 = (X-1400)/t1

<span>T = t2/t1  </span>

1400*T = X + 600

X*T - 1400*T = 2X - 600

X = 3600 meters

<span> River is 3600 meters wide</span>
