You buy a car for $40,000. in your research you find out the car will be worth $0 after 12 years. find the depreciation. what does this number tell you?

3333

This value of depreciation every year will get the car value to .

Step-by-step explanation:

Given: Purchase value of car(b) =

           Time(x) = 12

            Residual value(y) =

            Depreciation value= m

We will use straight line depreciation method with negative slope to find depreciation value.

Y= -mx + b

⇒ 0 =

We will subtract both side by 40000

⇒ -40000 =

Now, divide both side by -12

⇒ m = ≅ 3333

∴ Depreciation value for every year will be

This value of depreciation every year will get the car value to .

"it's not the heat, it's the humidity".   that's a partly valid phrase you may have heard in the summer, but it's actually both.   the heat index, also known as the apparent temperature, is what the temperature feels like to the human body when relative humidity is combined with the air temperature.   this has important considerations for the human body's comfort.   when the body gets too hot, it begins to perspire or sweat to cool itself off.   if the perspiration is not able to evaporate, the body cannot regulate its temperature.   evaporation is a cooling process.   when perspiration is evaporated off the body, it effectively reduces the body's temperature.   when the atmospheric moisture content (i.e. relative humidity) is high, the rate of perspiration from the body decreases.   in other words, the human body feels warmer in humid conditions.   the opposite is true when the relative humidity decreases because the rate of perspiration increases.   the body actually feels cooler in arid conditions.   there is direct relationship between the air temperature and relative humidity and the heat index, meaning as the air temperature and relative humidity increase (decrease), the heat index increases (decreases).
