Answer:

See below. I assume that (x) = 8x2 - 7x + 3 is really (x) = 8x^2 - 7x + 3

Step-by-step explanation:

Substitute the value of x given in f(x) into the equation f(x) = 8x^2 - 7x + 3

For example, f(0) would be f(0) = 8(0)^2 - 7(0) + 3. f(0) = 3

f(-2) would be f(-2) = 8(-2)^2 - 7(-2) + 3.

= 8*4 + 14 +3

= 32 + 17 therefore f(-2) = 49

x f(x)

A four-door sedan costs$35000 with a residual value of $2000. Its service life is five years. Using the declining balance method

larisa [96]

Answer:

At the end of the 2 year, the book value of the truck is $12,600

Step-by-step explanation:

we know that

Double declining balance method is a form of an accelerated depreciation method in which the asset value is depreciated at twice the rate it is done in the straight-line method.

Step 1

Determine the straight-line depreciation rate

Divide the total cost by the number of years in the asset's useful life.

$\frac{\$35,000}{5}=\$7,000$

Step 2

Then, multiply that number by 2 and that is your Double-Declining Depreciation Rate

$7,000(2)=\$14,000$ -----> is the depreciation for Year 1

Step 3

At the end of the first year, the book value of the truck is

$\$35,000-\$14,000=\$21,000$

Step 4

For Year 2, we will apply the same formula to the book value of the truck by the end of Year 1

$\frac{\$21,000}{5}=\$4,200$

$4,200(2)=\$8,400$ -----> is the depreciation for Year 2

therefore

At the end of the 2 year, the book value of the truck is

$\$21,000-\$8,400=\$12,600$

Michael has a substantial student debt, but he recently got a new job, which came with a signing bonus. He calculates that with

kykrilka [37]

Answer:

5000

Step-by-step explanation:

Given the question :

The size of debt after m months is respresented by the expression :

36,700 - (5000 + 500m)

Since Michael has decided to dedicate the entirety of his signing bonus towards paying his debt, then that is a constant and one-off payment.

Also, a fixed portion of his salary each month has also been assigned towards paying off his debt,

Then the amount paid from his salary after a certain number of months will be:

Fixed amount × number of months = 500 × m

Amount paid using signing bonus will be a constant = 5000

Total debt amount = 36,700

Size of debt left after m months :

Total debt - ( signing bonus - fixed amount × m)

Hence signing bonus = 5000
