The value of a car decreases by 20 percent per year. Mr. Sing purchases a $22,000 automobile. What is the value of the car at the end of the second year?
$14,080
$17,600
$19,800
$26,400
Answer:
$14,080
Step-by-step explanation:
You can use a formula for exponential decay, but since it is only 2 years, you can find 80% of the original value, and then 80% of the new value.
Original value: $22,000
Value after 1 year: 80% of $22,000 = 0.8 * $22,000 = $17,600
Value after 1 year: $17,600
Value after 2 years: 80% of $17,600 = 0.8 * $17,600 = $14,080
Answer: $14,080
Answer:
it is A , 14,080

The equation below shows the cost, in dollars, of a T-shirt, selling at $12.00, and 3 pairs of socks. What is the cost of one pair of socks, s? 12 + 3s = 42
Answer:
The answer is one pair of socks = $10
Step-by-step explanation:
I subtracted 42 by 12 and got 30. I then divided 30 and 3 and got 10.
42-12=30
30/3=10
Or you can subtract 12 from both sides to get the variable on one side. Then you divide the variable by the coefficient (3) and divide 30 by 3 to get 10.

A cheetah can run 97 km/hour. How fast can it run in 90 seconds? Round your answer
to the nearest hundredth.
The cheetah can run 2.42 km in 90 seconds
Calculating distanceFrom the question, we are to determine how fast the cheetah could run in 90 seconds
First, we will convert the speed to meter/seconds
The given speed = 97 km/hour
97 km/ hour = (97 × 1000 /3600) m/s
97 km/hours = 26.9444 m/s
Now, using the formula,
Distance = Speed × Time
From the given information,
Time = 90 seconds
∴ Distance = 26.9444 × 90
Distance = 2424.996 m
Distance = 2.424996 km
Distance ≅ 2.42 km
Hence, the cheetah can run 2.42 km in 90 seconds

What is the equation of the line that is perpendicular to the line y equal minus 1 over 2 open parentheses x minus 18 close parentheses and intersects the y-axis at open parentheses 0 comma space minus 1 close parentheses ?
Given:
The equation of line is
[tex]y=-\dfrac{1}{2}(x-18)[/tex]
The perpendicular line intersect the y-axis at (0,-1).
To find:
Equation of perpendicular line.
Solution:
Point slope form of a line is [tex]y-y_1=m(x-x_1)[/tex], where m is slope.
We have,
[tex]y=-\dfrac{1}{2}(x-18)[/tex]
Thus, the slope of this line is [tex]m_1=-\dfrac{1}{2}[/tex].
Product of slopes of two perpendicular lines is -1.
Let the slope of perpendicular line is [tex]m_2[/tex]. Then,
[tex]m_1\times m_2=-1[/tex]
[tex]-\dfrac{1}{2}\times m_2=-1[/tex]
[tex]m_2=2[/tex]
Slope of perpendicular line is 2 and it passes through (0,-1). So, the equation of perpendicular line is
[tex]y-(-1)=2(x-0)[/tex]
[tex]y+1=2x[/tex]
[tex]y=2x-1[/tex]
Therefore, equation of perpendicular line is [tex]y=2x-1[/tex].

The function rule to find the cost to ship a package that weighs [x] ounces is c[x] = 0.85x + 5.5.
What is Equation Modelling?Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.
Given is the cost of shipping a package overnight from San Antonio to Dallas, which is $5.50 plus $0.85 per ounce.
We can write -
Fixed cost of shipping overnight = $5.50
Cost per ounce for shipping = $0.85
The function rule that could be used to find the cost to ship a package that weighs [x] ounces will be -
c[x] = 0.85x + 5.5
Therefore, the function rule to find the cost to ship a package that weighs [x] ounces is c[x] = 0.85x + 5.5.

Write a function to represent the set of ordered pairs.
{(2, 2), (3,7). (4, 14), (5,23)}
Answer:
Step-by-step explanation:
The set of ordered pairs {(1 , 7) , (−1 , 7) , (8 , −6) , (−3 , 2)} is a function
The set of ordered pairs {(4 , 7) , (−1 , 2) , (4 , −6) , (−3 , −2)} is not a

An ordered pair represents a relationship between two values
The first value is the input the second value is the output
1. A relation is a set of inputs and outputs
2. A function is a relation with one output for each input
3. All functions are relations
{(1 , 7) , (−1 , 7) , (8 , −6) , (−3 , 2)}
∵ Each x-coordinate in each ordered pair has only one y-coordinate
∴ The relation above is a function

∵ The x-coordinate 4 has two values of y (7 and -6)
