A car was purchased for $39150.00 and is expected to be worth $10800.00 in 9 years. Determine the rate at which the van deprecia
ser-zykov [4K]

Answer:

<u>The annual rate of depreciation of the car is 8.05% or 72.41/9</u>

Step-by-step explanation:

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

Price of the purchase of the car = $ 39,150

Price after 9 years = $ 10,800

2. Determine the rate at which the van depreciates in value.

Let's calculate what is the percentage of depreciation after 9 years, this way:

Percentage of depreciation after 9 years = [1 - (Price after 9 years/Price of the purchase of the car)] * 100

Replacing with the values we know:

Percentage of depreciation after 9 years = [1 - (10,800/39,150)] * 100

Percentage of depreciation after 9 years = [1 - 0.2759] * 100

Percentage of depreciation after 9 years = 72.41%

<u>Annual rate of depreciation = 72.41/9 = 8.05%</u>

Someone please help me I will be so thankful
Volgvan
1/2 = 0.5 = 50% was found.

Looking at the scale, there are 5 dashes from 0 to 10,000.  This means that each dash is worth $2,000.  The thermometer is marked 2.5 dashes up; 2.5(2000) = 5000.  

5000/1000 = 1/2; 1/2 = 0.5; 0.5 = 50%.

Find a cubic function with the given zeros. Square root of seven. , - Square root of seven. , -4
yan [13]

Answer:

y= x^{3} +4x^{2}-7x-28

Step-by-step explanation:

We have to find a cubic function of x whose zeros are at x = √7, x = -√7 and at x = -4.

Therefore, the factors of the function will be (x - √7), (x + √7), and (x + 4)

Hence, the equation will be y = (x - √7) (x + √7) (x + 4)

⇒ y = (x^{2} -7)(x +4)

⇒ y= x^{3} +4x^{2}-7x-28 (Answer)
