A machine costing $56,745 with a 7-year life and $51,208 depreciable cost was purchased January 1. Compute the yearly depreciati

Pie

Answer:

$7315

Step-by-step explanation:

To find the depreciation expense, we use this formula:

Depreciable cost ÷ useful life time

Depreciated cost = $51,208

Life time = 7 years

51,208 ÷ 7 = 7315.42857

This means that $51,208 were lost over the 7 years, meaning $7315 were lost every year.

Triangle PQR has vertices P(4,-1),Q(-2,7), and R(9,9). Find an equation of the median and altitude from R.

Reil [10]

If we are drawing altitude from R the PQ will be base of this triangle. So we can say Median from R will cut on Midpoint of PQ. So firstly we will find mid point of PQ Which is S given as below:
P(4,-1) , Q (-2,7)

Let Co-ordinate of S is (x,y)
So $x = \frac{x_1+x_2}{2}$
$x = \frac{4-2}{2} = \frac{2}{2} = 1$

$y = \frac{y_1+y_2}{2}$
$y = \frac{-1+7}{2} = \frac{6}{2}= 3$
So midpoint of PQ is S(1,3).

Now we can find equation of RS
Co-ordinate of R is (9,9) and and S is (1,3).

In general equation of line from two point $(x_1 , y_1)$ and $(x_2,y_2)$ is
$(y-y_1) = \frac{y_2-y_1}{x__2-x_1}(x-x_1)$

So equation of RS is

$(y-9) = \frac{9-3}{9-1} (x-1)$
$(y-9) = \frac{6}{8}(x-1)$
$8(y-9) = 6(x-1)$
$8y-72 = 6x - 6$
$-72+6 = 6x - 8y$
$-66 = 6x-8y$

So the equation of median is 6x - 8y = -66

Recycled CDs, Incorporated, offers a choice of 5 used CDS for $20, with each additional CD costing $4. Write a cost function for

Dmitry_Shevchenko [17]

The the cost of 13 CDs would be $30.

<h3>How to find the Cost Function?</h3>

A cost function is a function of input prices and output quantity whose value is the cost of making that output given those input prices, often applied through the use of the cost curve by companies to minimize cost and maximize production efficiency.

If $20 represents the cost of the 5 used CDs, than your formula would be "20 + 4x" , with x being the amount of extra CDs you purchase.

The number of CDs minus 5 is our x value, because the first 5 are the used CDs bundled into the $20 group. Thus;

26 + 4(13 - 5)

26 + 4(1)

26 + 4 = $30

Thus, we conclude that the cost of 13 CDs would be $30
