Given:
The equation is:

To find:
The equations that is equivalent to the given logarithmic equation.
Solution:
We have,

It can be written as:

![[\because e^{\ln x}=x]](https://tex.z-dn.net/?f=%5B%5Cbecause%20e%5E%7B%5Cln%20x%7D%3Dx%5D)
Therefore, the correct option is D.
Change it into the form
ax^2 + bx + c = 0
x^2 + 13x + 0 = 0
This equation has a common factor, x. Factorise it out.
<h2>x (x + 13) = 0</h2>
Answer:
$7,440.
Step-by-step explanation:
We have been given the tax rates as follows:
$0-$11,000 = No tax.
$11,000-$43,000 = 20%.
$43,000-$150,000 = 40%.
Earnings over $150,000 = 45%.
Since last year Carys earned $45,600, so we will have to find the tax paid by her for 11,000-43,000 at rate of 20%, then the tax for amount over 43,000 at the rate of 40%.





Therefore, Carys paid an amount of $7,440 in tax.
How you do this is using the formula speed = distance/time. So this is 100/5 which is 20 meters a second. Using the conversion factor (can google "20 meters per second is how many mile") 20 meters a second = 44.7 miles per hour.
In conclusion, the answer you're looking for is D. 44.7 miles per hour.
The answer is x=20. You isolate the square root. Eliminate the radical on the left handside. And then solve it!
