You are considering buying two different vehicles. • The first is a van at $20,523, and an estimated annual operating cost of $3200. • The second is a fuel-efficient car at $23,540 and an estimated annual operating cost of $2450. Use these equations to represent the cost (y) of the cars over x years: Y = 20,523 + 3200 X Y = 23,540 + 2450 X
Answer:
Fill in the following tables, using the equations.
Cost of owning and operating the vehicles
Vehicle 0 1 2 3 4 5 6
Van $20,523 $23,723 $26,923 $30,123 $33,323 $36,523 $39,723
Car $23,540 $25,990 $28,440 $30,890 $33,340 $35,790 $38,240
How much does each vehicle cost initially?
Van costs $20,523Car costs $23,540How much does each cost to operate for one year?
Van costs $3.200Car costs $2,450Which one initially costs less?
VanWhich one will cost less over the six years?
CarWhen do they cost about the same?
year 4: van accumulated costs $33,323 and car accumulated costs = $33,340By calculating the costs over various years, you can determine which vehicle is more cost-effective based on the expected ownership duration. For instance, over 5 years, the fuel-efficient car is cheaper.
To compare the total cost of the van and the fuel-efficient car over time, we will use the given equations:
For the van: Y = $20,523 + $3200XFor the fuel-efficient car: Y = $23,540 + $2450XHere, Y represents the total cost over X years. To determine which vehicle is more cost-effective over a certain period, we need to calculate and compare the costs for various values of X.
Example Calculation:
Suppose we compare the costs for 5 years.
For the van:In this 5-year scenario, the fuel-efficient car is cheaper than the van.
By performing similar calculations for different time periods, you can determine which vehicle is more cost-effective based on your expected ownership duration.

Answer:
Option D: 159 3/8 cm^3
Step-by-step explanation:
1. Let us rewrite the dimensions, and the options to make this a little more clear ~ (dimensions) 5 cm, 8 1/2 cm, 3 3/4 cm ⇒ (options) 17 1/4 cm^3, 18 3/4 cm^3, 27 1/4 cm^3, and 159 3/8 cm^3
2. To find the volume of most 3-dimensional figures, you would have to multiply the Base * height, so for a rectagular prism ⇒ Base * height = length * width * height
3. Substitute and compute the volume through algebra:
5 cm * 8 1/2 cm * 3 3/4 cm =
5 cm * 17/2 cm * 15/4 cm =
85/2 cm^2 * 15/4 cm =
1275/8 cm^3 =
159 3/8 cm^3
4. This means that the Volume of the Rectangular Prism = 159 3/8 cm^3 (Option D)
The volume of the rectangular prism is 159/8 cm³.
What is volume?The area that any three-dimensional solid occupies is known as its volume. These solids can take the form of a cube, cuboid, cone, cylinder, or sphere.
To find the volume of a rectangular prism, we multiply the length, width, and height.
The length of the prism is 5 cm, the height is 8 and one-half cm (or 17/2 cm), and the width is 3 and three-fourths cm (or 15/4 cm).
So, the volume is:
V = l × w × h
V = 5 cm × 15/4 cm × 17/2 cm
V = 159/8 cm³
Therefore, the volume of the rectangular prism is 159/8 cm³.

In the U.S., from 2004 - 2015, the correlation coefficient for the relationship
between the size of a cell phone data plan, x, and the number of text
messages sent, y, is r = +0.97. Describe the relationship between the data
plan size and the number of text messages sent in the U.S.
Answer:
There is a very strong positive correlation between size of a cell phone data plan and the number of text messages sent in the U.S.
Step-by-step explanation:
The correlation coefficient is a statistical degree that computes the strength of the linear relationship amid the relative movements of the two variables (i.e. dependent and independent).It ranges from -1 to +1.
Positive correlation is an association amid two variables in which both variables change in the same direction. A positive correlation occurs when one variable declines as the other variable declines, or one variable escalates while the other escalates.
Negative correlation is a relationship amid two variables in which one variable rises as the other falls, and vice versa.
The correlation coefficient for the relationship between the size of a cell phone data plan, x, and the number of text messages sent, y is:
r = +0.97.
The correlation value is very close to +1.
So, we can say that there is a very strong positive correlation between size of a cell phone data plan and the number of text messages sent in the U.S.
A flexible wire is bent into a semicircular arc. The length of AB is 18 meters. Find the length of the wire. Use 3.14 as an approximation for π .
Answer: 28.26 meters
Step-by-step explanation:
Hi, to answer this question we have to find the perimeter of the semicircle.
P = (2 π r ) /2 (perimeter of a circle divided by 2)
The length of AB is the diameter of the circle (18 meters)
Since
Diameter (d) = 2 radius (r)
Replacing with the value given:
18 =2r
18/2=r
9 =r
Back on the perimeter formula
P = (2 π r ) /2
Replacing with the values given
P = (2 x 3.14 x 9) /2
P = 28.26 meters
Answer:
he's right it is 28.26

Lisa surveyed 50 randomly selected students to find out if they thought their school should start a recycling program of the 50 students
surveyed, 42 answered "yes."
If all 375 students in the school were asked the same question, approximately how many students are likely to answer "yes"?
A. 158
B. 283
C. 315
D. 333
E. 367
315 students would answer "yes". If 42 out of 50 students answered yes, that'd be 84% (you can determine this by dividing 42/50). Once you've determined that part, you can multiply 375 by 0.84 (converting a percentage to a decimal), which would give you 315.
Please mark brainliest if this helped in any way, thank you! Have a great day! :)
Out of 50 surveyed students, 84% answered 'yes' to the question about starting a recycling program. Applying this percentage to the whole school of 375 students, we estimate that about 315 would say 'yes'. So, the correct choice is C. 315.
Explanation:To answer this question, we first need to find out what fraction of students surveyed answered 'yes'. In this case, it's 42 out of 50 students, or 84%. If we apply this percentage to the entire school population, we can estimate how many of the 375 students would likely answer 'yes'.
To do this, you multiply the total number of students (375) by the percentage that answered 'yes' (.84 or 84%) which would give us 315.
So, out of 375 students, we can estimate that approximately 315 would answer 'yes' to the question about starting a recycling program. Hence, the correct answer is C. 315.

The graph of r = 1/ 1-5 sin theta is symmetric about the
Answer:
A. y-axis only
Step-by-step explanation:
We have the graph of as given below.
It can be seen that passes through the points (0,0), (4,0) and (6,0).
Also, the graph is plotted in the 1st and 2nd quadrant symmetrically along the y-axis.
Hence, the axis of symmetry of is the y-axis only.
The graph of r = 1/ (1 - 5sinθ) is symmetric about the y-axis only.
How to write polar coordinates?It expresses x and y in terms of r and θ:
x = r cos(θ) , y = r sin(θ)
In polar coordinates, the x-axis corresponds to θ = π/2 and the y-axis corresponds to θ = 0 (or θ = π). So to test for symmetry, we need to check whether replacing θ with π - θ (which reflects the graph across the y-axis) or replacing r with -r (which reflects the graph across the origin) gives us the same equation.
If we replace θ with π - θ, we get:
r = 1 / (1 - 5sin(π - θ)) = 1 / (1 + 5sinθ)
This equation is not the same as the original equation, so there is no symmetry about the y-axis.
If we replace r with -r, we get:
-r = 1 / (1 - 5sinθ)
Multiplying both sides by -1, we get:
r = -1 / (1 - 5sinθ)
This equation is also not the same as the original equation, so there is no symmetry about the origin.
However, if we replace θ with π/2 - θ, we get:
r = 1 / (1 - 5sin(π/2 - θ)) = 1 / (1 + 5cosθ)
This equation is the same as the original equation, so the graph is symmetric about the y-axis.
Therefore, the graph of r = 1/ (1 - 5sinθ) is symmetric about the y-axis only.

Does the function f(x) = x^3-4x^2+2x-6/x-3 have a slant asymptote? If so, find an equation of the slant asymptote. If not, explain
Answer:
No slant asymptote.
Step-by-step explanation:
No it hasn't .
If we do the division we find the quotient is a trinomial in x^2 so not a straight line, so there is no slant asymptote.
The one asymptote is the vertical line x = 3, because when x = 3 the denominator becomes 0.
Final answer:
To find the slant asymptote for the given function f(x), perform long division of the numerator by the denominator. The result is a quadratic function, which is the equation of the slant asymptote, specifically y = x^2 - x - 3.
Explanation:
The function f(x) = (x^3 - 4x^2 + 2x - 6)/(x - 3) does indeed have a slant asymptote, since the degree of the numerator is exactly one more than the degree of the denominator. To find the equation of the slant asymptote, you may perform polynomial long division or synthetic division. You would divide x^3 - 4x^2 + 2x - 6 by x - 3 to obtain the quotient which will be the equation of the slant asymptote.
When you do that, you'll find that the quotient is x^2 - x - 3. Since there's no remainder, or the remainder is of lesser degree than the denominator, the function approaches the line y = x^2 - x - 3 as x approaches infinity or negative infinity. This quadratic function is the slant asymptote for f(x).
