Solving Rational equations. LCD method. Show work. Image attached.

kenny6666 [7]

Answer:

$m=-\frac{3}{2}$

Step-by-step explanation:

The given equation is

$\frac{m}{m+1}+\frac{5}{m-1}=1$

The Least Common Denominator is $(m-1)(m+1)$ .

We multiply through by the LCD to get;

$(m-1)(m+1)\times \frac{m}{m+1}+(m-1)(m+1)\times\frac{5}{m-1}=(m-1)(m+1)\times1$

Simplify

$(m-1)\times \frac{m}{1}+(1)(m+1)\times\frac{5}{1}=(m-1)(m+1)\times1$

$m(m-1)+5(m+1)=(m-1)(m+1)$

Expand;(Use difference of two squares on the right hand side)

$m^2-m+5m+5=m^2-1$

Group similar terms;

$m^2-m^2-m+5m=-1-5$

Simplify;

$4m=-6$

Divide through by 4.

$m=\frac{-6}{4}$

$m=-\frac{3}{2}$

Give the “best” big-oh notation to describe the complexity of the algorithm that prints all bit strings of length n.

artcher [175]

It is correct to state that a bit can be in one of 2 states, either 1 or 0.

A bit is is a single binary digit. A bit can either be "1" or "0".

<h3>What is the explanation to the above answer?</h3>

We stated that It is correct to indicate that a bit can be in one of 2 states, either 1 or 0. This indicates that 2ⁿ strings must be created in total. The string must then be processed twice.

The first time, for generation and
The second for reading.

Hence, Our time is now O(2ⁿ⁺¹) = O(2ⁿ)

Which decimal is between 85 and V86?

Romashka-Z-Leto [24]

$\sf \large \underbrace{ \underline{Understanding \: the \: Question}}$

This can be considered as a very easy Question where you have to find the value of √85 and √86 upto 2 decimal places then we could find it easily.

Let's start!

Value of √85=9.21

Value of √86=9.27

Now it is obvious that 9.25 lies between √85 and √86.
