Dan's car depreciates at a rate of 15% per year. By what percentage has Dan's car depreciated after 3 years?​
Pavlova-9 [17]

The percentage of deprecation of the car in the third year is 38.59%.

<h3>What is deprecation?</h3>

Depreciation is the decline in the value of an asset as a result of wear and tear.

Deprecation in year 1 = 15%

Deprecation in year 2 = 15% x (100 - 15%) = 12.75%

Deprecation in year 3 = 15% x (85% - 12.75) = 10.84%

Sum of deprecation = 38.59%

|×|=×<br>is the absolute value of x always, sometimes, or never x​
il63 [147K]

Answer:

Sometimes

Step-by-step explanation:

I’ll give you an example so you can understand:

Let’s say x is 4. So plug 4 into the problem:

|4|=4  →  This is a very true statement, where the absolute value of 4 is equal to 4.

Now, let’s say x is -7. So plug -7 into the problem:

|-7|=-7  →  This is a false statement because it’s saying that the absolute value of -7 is -7 which is very untrue.

So |x|=x only works for positive numbers, but not negative numbers. Therefore, |x|=x is the absolute value of x <u>sometimes.</u>

<u />

Hope this helps and answers your question! :)
