Solve: In 2x + In 2 = 0<br> DONE

pychu [463]

Answer:

$x=\frac{1}{4}$

Step-by-step explanation:

We can use some logarithmic rules to solve this easily.

<em>Note: Ln means $Log_e$ </em>

<em />

Now, lets start with the equation:

$ln(2x) + ln(2) = 0\\ln(2x) = -ln(2)$

Writing left side with logarithmic base e, we have:

$Log_{e}(2x) = -ln(2)$

We can now use the property shown below to make this into exponential form:

$Log_{a}b=x\\means\\a^x=b$

So, we write:

$Log_{e}(2x) = -ln(2)\\e^{-ln(2)}=2x$

We recognize another property of exponentials:

$a^{bc}=(a^{b})^{c}$

So, we write:

$e^{-ln(2)}=2x\\(e^{ln(2)})^{-1}=2x$

Also, another property of natural logarithms is:

$e^{(ln(a))}=a$

Now, we simplify:

$(e^{ln(2)})^{-1}=2x\\(2)^{-1}=2x\\\frac{1}{2}=2x\\x=\frac{\frac{1}{2}}{2}\\x=\frac{1}{4}$

This is the answer.

A company plans to build at least 152 igloos in a single week by employing skilled workers from the cities of Tomsk and Kyzyl. A

Nikolay [14]

Answer:

each Tomskians will build 6 igloos per week

each Kyzylians will build 5 igloos per week

They achieved their goal

Step-by-step explanation:

6T + 5K ≥ 152

T = Tomskians

and each Tomskians will build 6 igloos per week

K = Kyzylians

and each Kyzylians will build 5 igloos per week

This is found by taking the coefficient on the inequality.

Substituting the values of T =10 and K = 19

6T + 5K ≥ 152

6*10 + 5*19 ≥ 152

60 + 95

155 ≥ 152

This is true, so they hired enough people.

A train leaves New Delhi at 4:00 p.m. and reaches Lucknow at midnight. Its speed is 55km/h. What is the distance between Delhi a

Bumek [7]

Answer:

$\boxed{440 km}$

Step-by-step explanation:

→ Work out time between New Delhi and Lucknow

12:00 - 4:00 = 8:00

→ State the speed formula

Speed = Distance ÷ Time

→ Rearrange to make distance the subject

Distance = Speed × Time

→ Substitute in the values

55 × 8 = 440 km
