Spencer estimates that his new car that costs $24,380 would be worth $13, 500 after two years and $8,230 after five years. a.) What will be the annual rate of depreciation for the first two years? b.) What will the percent be for the five years?

22.31%, 13.25%

Step-by-step explanation:

Given:

Spencer estimates that his new car that costs $24,380 would be worth $13, 500 after two years

And would be worth $8,230 after five years.

Question asked:

What will be the annual rate of depreciation for the first two years ?

What will the percent be for the five years ?

Solution:

Cost of asset (new car) = $24,380

Scrap value of the car after two years = $13, 500

We have to find rate of depreciation for first two years.

So, useful life will be = 2 years

First of all we will find annual depreciation, then rate of depreciation.

Annual depreciation = 5440

Now,

Therefore, annual rate of depreciation for the first two years is 22.31%.

Similarly, we will find rate of depreciation for 5 years.

This time useful life, we will consider 5 years:

Scrap value = $8,230 after five years (given)

Annual depreciation = 3230

Therefore, annual rate of depreciation for the five years is 13.25%

  y= -3x is the required function.

step-by-step explanation:

we have been given a table:

x             y

0             0

1             -3

3             -9

-2             6

we can see that the values of y is -3 times the value of x

hence, the function would be: y= -3x.

put the values of x will give the same y as in the table that means function is satisfying the given table.

circle area = pi * radius^2

if diameter = 10 then radius = 5

circle area = pi * 5^2

circle area = pi * 25

circle area = 78.5398163397 square units
