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 .

the correct option is 2.

step-by-step explanation:

according to the given information triangle abc is a right angle triangle with right angle at a. segment ab is 5 and segment ac is 7. point d is on segment bc and angles adb and adc are right angles.

it is given that triangles abd, cad, and cba are similar.

two triangles are similar if their corresponding sides are proportional.

in triangle cba, using pythagoras theorem

                      )

triangle abd and cba are similar,

                            (2)

triangle cad and cba are similar,

                      )

using (1), (2) and (3), we get

hence proved.

therefore option 2 is correct.
