The formula for depreciation is V=P(1-r)t where P is the beginning price of the asset, r is the annual rate of depreciation writ
Bad White [126]

Answer:

The value of the car after 5 years is $ 13,035 to the nearest dollar.

Step-by-step explanation:

The formula for depreciation is

V=P(1-r)^t

where P=24,700\:dollars is the beginning price of the asset,

r=12\% is the annual rate of depreciation written as a decimal,

r=0.12

t=5 is the number of years, and V is the value after t years.


Now substitute all these values into the formula to get,

V=24,700(1-0.12)^5


This  simplifies to,

V=24,700(0.88)^5


\Rightarrow V=24,700(0.5277319168)


\Rightarrow V=13,034.97834


The value of the car after 5 years is $ 13,035 to the nearest dollar.

Can someone answer this please!!

Answer:

<u>The perimeter of the square is option E. 16√5 mm.</u>

<u>The area of the square is option A. 80 mm².</u>

Step-by-step explanation:

1. Let's calculate the perimeter of this square:

The perimeter of a square is the sum of its side 4 times, thus:

Perimeter = 4√5 + 4√5 + 4√5 + 4√5

<u>Perimeter = 16 √5</u>

<u>Perimeter = 4 * 4√5 = 16√5</u>

<u>The correct answer is option E. 16√5 mm</u>

2. Let's calculate the area of this square:

The area of a square is the length of its side squared, thus:

Area = (4√5)²

Area = 4√5 * 4√5

Area = (4 * 4 * √5 * √5)

Area = 16 * 5 = 80

<u>The correct answer is A. 80 mm²</u>
