Sammy bought a new car. the depreciation equation is given by f(x) = 30,000(.85)x, where x represents the number of years since the purchase of the car, and f(x) represents the value of the car. what is the initial value of the car?
a. $0
b. $25,500.00
c. $30,000.00
d. $35,294.12

C. $30,000

Step-by-step explanation:

Given: Sammy bought a new car. the depreciation equation is given by , where x represents the number of years since the purchase of the car, and f(x) represents the value of the car.

To calculate the initial value of the car, we need to put x=0 in the given equation, we get

Hence, the initial value of car is $30,000.

step-by-step explanation:

given perimeter: 28cm

length: 9cm

atp,

2(l+w)=p of the reactangle

2(9+x)=28

18+2x=28

2x=28-18

x=10/2

x=5

therefore width is 5 cm

x =±sqrt(1/3)

step-by-step explanation:

x+4/6x=1/x

multiply each side by 6x to get rid of the fractions

6x*(x+4/6x)=1/x*6x

distribute

6x^2 +4 = 6

subtract 4 from each side

6x^2 +4-4 = 6-4

6x^2 =2

divide by 6

6x^2/6 = 2/6

x^2 = 1/3

take the square root of each side

sqrt(x^2) = ±sqrt(1/3)

x =±sqrt(1/3)
