A new car is purchased for 18,000 dollars. The value of the car depreciates at 11.5% per year. What will the value of the car be, to the nearest cent, after 10 years?
Answer:
Step-by-step explanation:
The exponential decay function is
[tex]v(t)=a(b)^t[/tex] where b, the rate of decay, for us is (1 - .115) and a is the original value of the car which, for us, is 18000. t is the time in years. Using this information to write the equation we need to solve for the value when the car is 10 years old:
[tex]v(t)=18000(.885)^t[/tex] and we sub in 10 for t:
[tex]v(t)=18000(.885)^{10[/tex] which simplifies to
v(t) = 18000(.2947356754) so
v(t) = 5305.24

There are between 24 and 40 students in a
class.
The ratio of boys to girls is 4:7
How many students are in the class?
Answer:
Step-by-step explanation:
The ratio of boys is 4/11
You need a number that is divisible by 11.
11 represents the number of students in the class. That was obtained by adding 4 and 7 together. So there are 4/11 boys and 7/11 girls.
You could try 33 which is between 24 and 40
4/11 * 33 = 12
There are twelve boys in the class.
7/11 * 33 = 21
There are 21 girls in the class.
21 + 12 = 33 which is exactly what you need.

A family decides to hold two Christmas parties, one on Christmas Eve and one on Christmas Day. The youngest person to attend the Christmas Eve party is 15 and the oldest is 29. The youngest person to attend the Christmas Day party is 27 and the oldest is 42. Which party has a larger age range of visitors?
Answer:
Christmas Party
Step-by-step explanation:
Christmas Eve party :
Youngest = 15
Oldest = 29
Therefore , range = 29 - 15 = 14
Christmas Party :
Youngest = 27
Oldest = 42
Therefore, range = 42 - 27 = 15
Christmas Day party has a larger age range of visitors.
Given that: The youngest person to attend the Christmas Eve party is 15 and the oldest is 29. So the range is = 29 - 15 = 14.
Given that: The youngest person to attend the Christmas Day party is 27 and the oldest is 42. So, the range is = 42 - 27 = 15.
Since 15 > 14, so Christmas Day party has a larger age range of visitors.

Step-by-step explanation:
Chang used a coordinate plane to show where his posters are displayed on his bedroom wall. Three posters are located at E(5, 3), F(–4, 3), and G(–4, 5). Use absolute values of coordinates to find the distances between points E and F, and between points G and F. Enter your answers in the boxes. EF = units GF = units
Answer:
EF = 9
GF = 2
Step-by-step explanation:
For EF, we want to find the distance between their c coordinates, since their y coordinates are the same. We want the distance between -4 and 5, which when you add their distance from 0, is 9.
For GF, they share the same x coordinate, so you're finding the distance between their y coordinates, which are 3 and 5. The distance between the two is 2, so the length of GF is 2.

Answer:
B, E, F
Step-by-step explanation:
Answer:
B, F
Step-by-step explanation:
A is false; the slope of function Z is 1/4 and the slope of function W is 1/2. 1/2 is greater than 1/4.
B is true. The slope of function Z is less then the slope of function W.
C is false, the y-intercept of function Z is -2 and the y-intercept of function W is -1. They are not the same number.
D is false, the y-intercept of function W is greater than Function Z.
E is false, -3 and -3 are equal
Function W:
y = 1/2x - 1
y = 1/2(-4) - 1
y = -4/2 = -2
y = -2 - 1
y = -3
Function Z:
y = 1/4x - 2
y = 1/4(-4) - 2
y = -1 - 2
y = -3
F is true, if y = -4 for functions W and, they would both be equal.

A music website charges x dollars for individual songs and y dollars for entire albums. Person A pays $5.45 to download 2 individual songs and 3 albums. Person B pays $8.41 to download 5 individual songs and 4 albums. Write a system of linear equations that represents this situation. How much does the website charge to download a song? an entire album?
Answer:
Amount charged for downloading individual songs = x dollars
Amount charged for downloading an entire album = y dollars
In respect to person A:
6x + 2y = 25.92
3x + y = 12.96
y = 12.96 - 3x
In respect to person B:
4x + 3y = 33.93
Putting the value of y from the first equation in the second, we get
4x + 3(12.96 - 3x) = 33.93
4x + 38.88 - 9x = 33.93
- 5x = - 4.95
x = 0.99 dollars
Putting the value of x in the first equation, we get
y = 12.96 - 3x
= 12.96 - 2.97
= 9.99 dollars
