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.

Step-by-step explanation:

A is incorrect because the range of the data is basically just subtraction. The range of 20-40 year old men's heart rates are higher than 50-70 year old men. B is incorrect. Think of "median" as "middle". The heart rates of the 20-40 year old men is higher than the heart rates of the 50-70 year old men. C is incorrect, because the minimum heart rate is the "starting point" of the box plot, in these cases for the 20-40 year old men, that would be 75, which is higher than the 50-70 year old men.

The line plots below show the number of students in each of Andre’s and Mandy’s classes at school. Approximately how many times larger is the difference between the means of the number of students in Andre’s and Mandy’s classes compared to the range?

Answers

Answer:

the answer is 5.0

Step-by-step explanation:

The difference between the means of the Andre's and Mandy's classes are 1.42. [tex]X_{AM}=1.42X_{MM}[/tex]

What is mean?

The "mean" is the "average" you're used to, where you add up all the numbers and then divide by the number of numbers.

From the data given we will calculate the mean of andres's class students and mandy's class students.

For Andre's

[tex]X_{AM}=\dfrac{20+21+22+23+25}{5}=22.5[/tex]

For Mandy

[tex]X_{MM}=\dfrac{14+15+15+16+19}{5}=15.8[/tex]

So here we will compare the means

[tex]\dfrac{X_{AM}}{X_{MM}}=\dfrac{22.5}{15.8}=1.42[/tex]

[tex]X_{AM}=1.42X_{MM}[/tex]

13. A right triangle has sides 8 and 12.


a. Find the missing side if 8 and

12 are legs.


b. Find the missing side if 8 and

12 are a leg and hypotenuse.

Answers

A if 8 and 12 are legs the missing side would be 14.42
B if 8 is a leg and 12 is hypotenuse then the other leg would be 8.94
So the pythagorean theorem is a^2 + b^2 = c^2. in this case it would be 12^2 + 8^2 = c^ 2

Explanation:
12^2 = 144
8^2= 64
64 + 144 = c^2
208 = c^2
in order to find c we need to square root both sides of the equation, you can plug that into the calculator.
c = about 14.4
