1 answer:
Feliz [49]3 years ago
7 0

Answer:

-i

Step-by-step explanation:

(-i)^0 = 1

(-i)^1 = -i

(-i)^2 = -1

(-i)^3 = -i

(-i)^4 = 1

(-i)^5 = -i

etc.

From this pattern, you see that when the exponent is a multiple of 4, you get 1. When the exponent is a multiple of 4 plus 1, you get -i, etc.

213 = 4 * 53 + 1

213 is 1 more than a multiple of 4.

(-i)^213 = (-i)^1 = -i

A car dealership pays 8358 for a car they mark up the price by 17.4% to get the retail price. What is the retail price of the ca
Ede4ka [16]

Answer:

<u>The retail price of the car is US$ 10,024 Rounding to the next whole</u>

Step-by-step explanation:

1. Let's check the information given to us to answer the question correctly:

Mark up the purchase price = 17.4%

Price of purchase of the car = $ 8,538

2. What is the retail price of the car at this dealership?

For calculating the retail price of the car, we will use the Rule of Three Simple, this way:

x = retail price of the car

x * 1 = 8,538 * 1.174

x = 10,023.61

<u>The retail price of the car is US$ 10,024 Rounding to the next whole</u>

A company uses the declining-balance method of calculating depreciation expense. On January 1, the company buys machinery for $7
NeX [460]

Answer:

$516,000

Step-by-step explanation:

Given:

- Beginning boo value of asset A = $750,000

- The salvage value of the asset B = $100,000

- The estimated life of asset t = 10 years

Find:

What is the book value in year 3?

Solution:

- Under the declining balance method, double declining method depreciation rate (R) is calculated by:

                                  R = 1 / t

                                  R = 1 / 10 = 10%

- The accumulated depreciation for 3 years is as follows:

                                 Depreciation: ( A - B ) * R * 2

                 Year 1:     DDB = ( 750,000 - 100,000 ) * 0.2 = $130,000

                 Year 2:    DDB = ( 620,000 - 100,000)*0.2 = $104,000

- The book value in year 3 is:

                                 $ 620,000 - $104,200 = $516,000
