Answer: x=0.168

Step-by-step explanation:

To solve the equation e^{2x}=1.4 you need to apply natural logarithm to both sides of the equation:

ln(e)^{2x}=ln(1.4)

According to the logarithms property:

ln(b)^a=aln(b)

Then, applying the property, you get:

(2x)ln(e)=ln(1.4)

You need to remember the following:

ln(e)=1

Therefore:

2x(1)=ln(1.4)\\\\2x=ln(1.4)

And finally, you must divide both sides of the equation by 2:

\frac{2x}{2}=\frac{ln(1.4)}{2}\\\\x=0.1682

Rounded to the nearest thousand:

x=0.168

Answer:

x = 0.16823611831

Step-by-step explanation:

ln (natural log), when multiplied by e, cancels it out.

Therefore ln*e2x = ln*1.4

2x = 0.33647223662

x = 0.16823611831

allsm [11]

Answer:

3. $600,000

Step-by-step explanation:

We have been given that a tenant rented a store to use as a real estate school at a base rent of $1,500 a month. Additionally, the tenant agreed to pay 3% of gross annual sales over $200,000.

Let us find base annual rent.

\text{Base annual rent}=\$1500\times 12\\\\ \text{Base annual rent}=\$18,000

Let us find the amount of rent paid as 3% of gross annual sales.

\$30,000-\$18,000=\$12,000

Let us find amount of sales over $200,000 by dividing $12000 by 3% or 0.03.

\frac{\$12,000}{0.03}=\$400,000

Total sales would be $400,000 plus $200,000.

\text{Total sales}=\$400,000+\$200,000\\\\ \text{Total sales}=\$600,000

Therefore, the total sales for that year was $600,000 and 3rd option is the correct choice.
