A car costs $30,000 when purchased as new and depreciates at a rate of 18% per year.

1. Write an exponential decay model to represent the situation. Be sure to define the variables.
2. Find the value of the car after 10 years.

Answers

9514 1404 393
Answer:
v(t) = 30000×0.82^t . . . value in dollars after t years
v(10) ≈ 4123 . . . . dollars
Step-by-step explanation:
The general form of the decay model is ...
f(t) = f(0)×(1 -decay rate)^time
where the decay rate is a fraction between 0 and 1, and the time is expressed in the same time units as the decay rate. The multiplier f(0) is the initial value that is decaying.
In this problem, the initial value is $30,000 and the decay rate is 18% per year. So, we can write a function v(t), where v is the car's value in dollars, and t is the number of years after it starts depreciating.
v(t) = 30,000×(1 -0.18)^t
v(t) = 30,000×0.82^t
__
The car's value in 10 years is ...
v(t) = 30,000×0.82^10 ≈ 4123.44
The value of the car after 10 years is about $4,123.

Volume of  ceramic ball = [tex]\frac{4}{3}\pi r^{3}[/tex]

                                        [tex]= \frac{4}{3}*3.14*0.25*0.25*0.25\\\\= \frac{0.19625}{3}\\\\=0.07 cubic feet[/tex]

the length is 12 ft 3 inches.

147/12 = 12.25 and 1/4 of a foot is 3 inches so your answer is 12 ft 3 in

Answer:

12 ft 3 in

Step-by-step explanation:

12 feet would be 144 so you have to add three inches to get 147

another way to solve it would be to divide 147 by 12 to get 12.25 which is equal to 12 ft 3 in

Answer:

x=18

Step-by-step explanation:

Vertical angles mean that the angles are the same, diagonal from each other.

So, you can assume that <1=<3,

4x-14=58

Solve this as an equation

58+14=72

72/4=18

x=18

So because they are Vertical angles, they are equal! The equation would be (4x-14)=58. When you solve for that, you get x=18

Find the area of the figure and choose the appropriate result.

Answers

Answer:

A- 24m

B- 18.9

C. 11.4

Total- 54.3

Step-by-step explanation:

Answer:

41.7 square meters

Step-by-step explanation:

First, rectangle A:

4 x 6 = 24 square meters

Second, rectangle B:

We know the length of this section is 3.5m. For the height/width, we can look at rectangle C. The height of C is 3.8m, and we see the part of C that is NOT part of B is 2m long. So we subtract 2 from 3.8 to find the height of B.

3.8 - 2 = 1.8m

Then, for the area of B:

3.5 x 1.8 = 6.3 square meters

Third, rectangle C:

3 x 3.8 = 11.4 square meters

Add up areas of A, B, C:

24 + 6.3 + 11.4 = 41.7 square meters
