A motorcycle bought for $10,000 depreciates continuously at 9% per annum. What is the value after seven years round the answer t

Scilla [17]

Answer:

Book value= $62.83

Step-by-step explanation:

Giving the following information:

A motorcycle bought for $10,000 depreciates continuously at 9% per annum.

First, we need to calculate the depreciation of seven years:

FV= PV*{[1+(-i/100)]^n}

FV= 10,000*{[1+(-0.09/100)]^7}

FV= $9937.17

Book value= 10,000 - 9,937.17

Book value= $62.83

Distance Formula: $d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Step-by-step explanation:

Step 1: Define

Point (-2, 3)

Point (9, 3)

Step 2: Find distance d

Simply plug in the 2 coordinates into the distance formula to find distance d.

Substitute [DF]: $d = \sqrt{(9+2)^2+(3-3)^2}$
Add/Subtract: $d = \sqrt{(11)^2+(0)^2}$
Simplify: $d = \sqrt{(11)^2}$
Simplify: $d = 11$

1. Each row in a window display of floppy disk cartons contains two more boxes than the row above. The first row has one box. a.

Oduvanchick [21]

Each row has two more boxes than the row above. The first row has one box

The boxes in a row form an arithmetic sequence with the first term, a₁ = 1 and the common difference, d=2.
The n-th term is
$a_{n} = a+(n-1)d$
The sum of n terms is
$S_{n} = \frac{n}{2}(a_{1} + a_{n})$

Answer:
The table will have the following:

Row Number: 1 2 3 4 5 6
Boxes in the row: 1 3 5 7 9 11
Total boxes in the display: 1 4 9 16 25 36
