The Gordon family plans to buy a TV. One TV has a purchase price of $330 and an estimated yearly operating cost of $14. The other has a purchase price of $369 and an estimated yearly operating cost of $9. Which TV should the Gordons buy if they plan to keep it for 8 years? Use rational functions to help justify your answer.
ANSWER:rational functions that model the average annual cost of each television if it is owned for x years, such as f(x)= (330+14x)/x and
g(x)= (369+9x)/x
calculation proving that over 8 years, the annual cost for the $330 television is $55.25; for the $369 television, it is $55.13
statement that the Gordons should buy the $369 television because it is less expensive overall
step by step: edge 2023
Answer:
The Gordon's should buy TV2
Step-by-step explanation:
To determine which TV the Gordons should buy, we need to compare the total cost of each TV over the 8-year period. Let's define some variables:
- Let x be the number of years the TV is used.
- Let y1 be the total cost of TV 1 over x years.
- Let y2 be the total cost of TV 2 over x years.
- Let P1 be the purchase price of TV 1.
- Let P2 be the purchase price of TV 2.
- Let O1 be the annual operating cost of TV 1.
- Let O2 be the annual operating cost of TV 2.
Using these variables, we can write the following equations:
y1 = P1 + x * O1
y2 = P2 + x * O2
To compare the total cost of each TV over 8 years, we need to find y1 and y2 when x = 8. Plugging in the given values, we get:
y1 = 330 + 8 * 14 = 462
y2 = 369 + 8 * 9 = 441
Therefore, the total cost of TV 1 over 8 years is $462, and the total cost of TV 2 over 8 years is $441. Since TV 2 has the lower total cost, the Gordons should buy TV 2.
From a mathematical standpoint, we can also use rational functions to analyze this problem. The total cost of each TV is a linear function of x, so we can write:
y1(x) = P1 + x * O1
y2(x) = P2 + x * O2
The ratio of these functions is:
y1(x) / y2(x) = (P1 + x * O1) / (P2 + x * O2)
To determine which TV is cheaper over 8 years, we need to compare the ratios when x = 8:
y1(8) / y2(8) = (330 + 8 * 14) / (369 + 8 * 9) ≈ 1.051
Since this ratio is greater than 1, TV 1 is more expensive than TV 2 over 8 years. Therefore, the Gordons should buy TV 2.

What is Quadratic equation?
A quadratic equation is a second-degree polynomial equation in a single variable of the form ax^{2} + bx + c = 0, where a, b, and c are constants and x is the variable. The highest exponent of the variable in a quadratic equation is 2, and the equation can be written in standard form, where the coefficient of the squared term (a) is not equal to zero.
The given expression is:
5x² - √3x + 2
This is a quadratic expression in the variable x, which means that it can be written in the form of ax² + bx + c, where a, b, and c are constants. In this case, we have:
a = 5
b = -√3
c = 2
We can use the quadratic formula to find the roots of this expression:
x = [-b ± √(b² - 4ac)] / 2a
Now, putting the values of a, b, and c, we get:
x = [-(-√3) ± √((-√3)² - 4(5)(2))] / 2(5)
Now, Simplifying the expression under the square root, we get:
x = [√3 ± √(-71)] / 10
Since the expression under the square root is negative, there are no real roots to this equation. Therefore, the expression 5x² - √3x + 2 has no real solutions.

luke wants to buy an ipod. determine the equivalent cash price if luke makes 18 monthly payments of $31.48 at an interest rate of 15.2% compounded monthly
Answer:
We can use the formula for the present value of an annuity:
PV = PMT x [(1 - (1 + r)^(-n)) / r]
where PV is the present value, PMT is the monthly payment, r is the monthly interest rate, and n is the number of payments.
Substituting the given values, we have:
PV = $31.48 x [(1 - (1 + 0.152/12)^(-18)) / (0.152/12)]
PV = $31.48 x [(1 - 0.5159) / 0.0127]
PV = $1,007.97
Therefore, the equivalent cash price of the iPod is $1,007.97.

Rewrite quadratic function in standard form
Since the function is already in standard form (ax^2 + bx + c form) you don't have to change anything and simply rewrite it.
For the vertex, if you have a quadratic function in standard form -b/2a is the x value of the vertex.
-b/2a = -4/(2(2)) = -1
Since we now know the x-value of the vertex we can plug it into the function to find the corresponding y-value.
h(-1) = 2(-1)^2 + 4(-1) - 10 = -12
So, the vertex is at (-1,-12)

What is triangle?
A triangle is a three-sided polygon, which is a flat shape with straight sides. It is a basic shape in geometry and has many interesting properties that are useful in mathematics and other fields.
The formula for the area of a triangle is A = 1/2 * b * h, where A is the area, b is the length of the base, and h is the height of the triangle.
In this case, we know that the area of the triangle is 21 in² and the height is 7 in. So we can substitute these values into the formula and solve for the base:
21 = 1/2 * b * 7
Multiplying both sides by 2:
42 = b * 7
Dividing both sides by 7:
6 = b
Therefore, the length of the base is 6 inches.

The area of the sector formed by angle DFE is approximately 3.29 square feet.
What is area of the sector?
To find the area of a sector of a circle, we need to know the central angle that defines the sector and the radius of the circle. We can then use the formula:
Area of sector = (central angle / 360 degrees) x π x (radius)²
In this case, we are given that the radius of the circle is 4 feet and the central angle that defines the sector is 75 degrees. Therefore, the area of the sector can be calculated as:
Area of sector = (75 / 360) x π x (4)²
= (0.2083) x π x 16
= 3.29 square feet (rounded to the nearest hundredth)
Therefore, the area of the sector formed by angle DFE is approximately 3.29 square feet.

Part B: The y-intercept of line p is (0, 4). When multiplied by the dilation factor of 2, the y-intercept of line q is (0, 8).
What is a slope?A slope is a measure of how steep a line is when plotted on a graph. It is calculated by finding the ratio of the "rise" (vertical change) over the "run" (horizontal change). Slopes can be positive, negative, zero, or undefined. A positive slope is one where the line rises from left to right and a negative slope is one where the line falls from left to right.
Part A: The slope of line q can be determined by calculating the slope of line p and multiplying it by the dilation factor. The slope of line p is 4, so when multiplied by the dilation factor of 2, the slope of line q is 8.
Part B: The y-intercept of line q can be determined by calculating the y-intercept of line p and adjusting it for the dilation factor. The y-intercept of line p is (0, 4). When multiplied by the dilation factor of 2, the y-intercept of line q is (0, 8).
Line segment P'Q is created by the two points (8, 5) and (12, 8). Using the distance formula, the length of line segment P'Q can be determined. The formula for the distance between two points is (x2-x1)² + (y2-y1)². Substituting the coordinates for points P and Q into the formula, the length of line segment P'Q is calculated as (12-8)² + (8-5)²= 9. Therefore, the length of line segment P'Q is 9 units.

Elon needs 60 6060 yards worth of edge material. Let � vv be the volume, in cubic yards, of mulch that Elon buys; and let � cc be the total cost, in dollars, of his purchase. Which of the following equations correctly relates � vv and � cc?
The correct equation relating the volume of mulch purchased (v) and the total cost of the purchase (c) is: c = 33v + 720
What is total cost?The total cost formula is used to combine the variable and fixed costs of providing goods to determine a total.
The cost of the mulch depends on the volume purchased, so the equation relating the volume of mulch purchased (v) and the cost of the purchase (c) is:
c = 33v
The cost for 5 yards of edge material is $60, so the cost for 60 yards of edge material is:
60/5 x 60 = $720
Therefore, the total cost of the purchase is the sum of the cost of the mulch and the cost of the edge material:
total cost = cost of mulch + cost of edge material
c = 33v + 720
So the correct equation relating the volume of mulch purchased (v) and the total cost of the purchase (c) is: c = 33v + 720

numbers is 6. What are the values of X, Y, and Z? Show your work
The X, Y, and Z values are 84, 90, and 90, respectively. To answer this question, we need to understand the meaning of the words "median", "mean" and "range".
What is median?Median is the middle number of a set of numbers - it is the number in the middle when the numbers are ordered from smallest to largest.
Since the median is 90, this means that Y (the mean number) is 90. Since the average is 92, this means that the sum of the three numbers is 276 (92 x 3). The interval is 6, which means that the difference between the largest number and the smallest number is 6.
To solve for X and Z, we can use the equation X Y Z = 276. We know that Y is 90, so we can plug 90 into Y:
X 90 Z = 276
Then we can subtract 90 from both sides to find the value of X and Z:
X Z = 186
Since the range of the three numbers is 6, this means that X and Z must be 6 plus. The only two numbers that differ by six and add up to 186 are 84 and 90.
Therefore the X, Y, and Z values are 84, 90, and 90, respectively.

A block of metal with volume 15 m³ 3 and density 8,800 kg/m³ is combined with another metal of 3 mass 850 kg and volume 6.2 m³ to form an alloy. What is the density of the alloy to the nearest integer?
Answer:
Step-by-step explanation:
The total mass of the alloy is the sum of the masses of the two metals:
mass = density x volume = (8800 kg/m³ x 15 m³) + 850 kg = 132,000 kg + 850 kg = 132,850 kg
The total volume of the alloy is the sum of the volumes of the two metals:
volume = 15 m³ + 6.2 m³ = 21.2 m³
Therefore, the density of the alloy is:
density = mass / volume = 132,850 kg / 21.2 m³ ≈ 6266 kg/m³
Rounding to the nearest integer, the density of the alloy is 6266 kg/m³.

I have two fair dice each numbered 1 to 6. I am going to throw the two dice. What is the probality that the sum of the numbers of the dice will be a square number?
Answer:
7/36
Step-by-step explanation:
It is given that we have two dice numbered from 1 to 6 . The maximum sum that can be obtained by rolling two dice is 6+6 = 12 and the minimum sum that can be obtained by rolling is 1+1 = 2 .
Now between 2 and 12 , the numbers which are perfect square are 4 and 9 .
Getting a sum of 4 :-
We can get a sum of four from two dice as ,
1 on first dice, 3 on other.2 on first dice , 2 on other.3 on first dice , 1 on other.Getting a sum of 9 :-
3 on first dice, 6 on other.6 on first dice, 3 on other.4 on first dice, 5 on other.5 on first dice, 4 on other.So there are a total of 7 possibilities by which we can can get a perfect square number by rolling two dices .
Now total number of possible outcomes = 6*6 = 36 .
Henceforth the required probability would be ,
[tex]\rm\implies P( getting \ a \ square\ number) =\dfrac{Total \ number\ of \ favourable\ outcomes}{Total \ number \ of \ possible \ outcomes} [/tex]
[tex]\rm\implies \underline{\underline{\red{ P( getting \ a \ square\ number)=\dfrac{7}{36}}}}[/tex]
Hence the required probability is 7/36 .
The probability of getting a square number as the sum is therefore 7/36.
WHAT IS PROBABILITY ?
Probability is a branch of mathematics that deals with the study of random events or phenomena. It involves analyzing the likelihood of an event occurring, given the conditions or circumstances that surround it. Probability is expressed as a number between 0 and 1, where 0 represents an impossible event and 1 represents a certain event. The probability of an event is determined by dividing the number of favorable outcomes by the total number of possible outcomes. Probability is widely used in many fields, including statistics, physics, finance, engineering, and social sciences, to name a few.
There are 36 possible outcomes when two dice are thrown since each die has 6 possible outcomes.
Let's find the possible outcomes where the sum of the numbers on the dice is a square number. The only possible sums that are squares are 4, 9 and 16.
To get a sum of 4, the dice must land on 1 and 3 or 3 and 1. There are two possible ways of doing this, so there are 2 outcomes.
To get a sum of 9, the dice must land on 3 and 6, 4 and 5, 5 and 4, or 6 and 3. There are four possible ways of doing this, so there are 4 outcomes.
To get a sum of 16, the dice must both land on 6. There is only one possible way of doing this, so there is 1 outcome.
Therefore, there are 2 + 4 + 1 = 7 outcomes where the sum of the numbers on the dice is a square number.
The probability of getting a square number as the sum is therefore 7/36.

Simultaneous Equations
y=x-2
y=3x+5
Hello and regards kiann09.
So the solution of the equation is:
x = - 7/2y = - 11/2Step-by-step explanation:y = x - 2
y = 3x + 5
We substitute the given value of y into the equation y = 3x + 5.
x - 2 = 3x + 5
We solve the equation for x.
x - 2 - 3x = 5
We move the variable to the left side and change its sign.
The sign of the variable must be changed because, in the process of "moving the variable", we are adding its opposite to both sides.
x - 2 - 3x = 5
Now we move the constant to the right hand side and change its sign.
x - 3x = 5 + 2
We group like terms.
-2x = 5 + 2 ⇒ We add the numbers ⇒ -2x + 7
We must divide both sides by -2.
x = - 7/2
We substitute the given value of x into the equation y = x - 2.
y = (-7/2)-2
We solve the equation for y. We write all the numerators above the common denominator.
y = -(7 + 4)/2
y = - 11/2

The box plots below show data from a survey of students under 14 years old. They were asked on how many days in a month they read and draw. Based on the box plots, which is a true statement about students? pg780337 A Most students read less than 12 days a month. B Most students draw at least 12 days a month. C Most students draw more often than they read. D Most students read more often than they draw.
The Correct answer is D) Most students read more often than they draw.as the median of the "read" plot is lower than the median of the "draw" plot.
Based on the box plots, we can see that:
The median for the "read" data is around 8 days per month, and the interquartile range (IQR) is between 4 and 12 days.
The median for the "draw" data is around 12 days per month, and the IQR is between 8 and 16 days.
So, we can conclude that:
A) Most students read less than 12 days a month. This is true, since the median for the "read" data is below 12 days per month, and the box plot shows that most of the data is concentrated in the lower half of the range.
B) Most students draw at least 12 days a month. This is not true, since the median for the "draw" data is around 12 days per month, and the box plot shows that there is a considerable amount of data below that median.
C) Most students draw more often than they read. This is not true, since the median for the "read" data is lower than the median for the "draw" data.
D) Most students read more often than they draw. This is true, since the median for the "read" data is lower than the median for the "draw" data, and the box plot shows that most of the "read" data is concentrated in the lower half of the range, while most of the "draw" data is concentrated in the upper half of the range.

Decomposing numbers to add make a new 10 adding.
29+14
29 + 14 = 44 by decomposing numbers to add and make a new 10.
Describe Decomposition of numbers?Decomposition of numbers involves breaking a number down into its constituent parts or smaller numbers that add up to the original number. This can be done in different ways depending on the purpose and context of the problem.
For example, one common way of decomposing a number is by place value. In this case, the number is broken down into its digits, which represent different powers of ten. For instance, the number 562 can be decomposed into 500 + 60 + 2.
Another way of decomposing numbers is by factoring. In this case, the number is expressed as a product of its factors. For example, the number 12 can be decomposed as 2 x 2 x 3.
Decomposing numbers is a useful skill in many areas of mathematics, including arithmetic, algebra, and geometry. It is often used to simplify problems, make computations easier, and facilitate further analysis.
To decompose 29 to make a new 10, we can break it into 9 and 20. Then, to decompose 14 to make a new 10, we can break it into 6 and 8.
So, we have:
29 + 14 = (9 + 20) + (6 + 8)
Now, we can regroup the numbers to make a new 10:
= (9 + 1) + (20 + 6) + 8
= 10 + 26 + 8
= 44
Therefore, 29 + 14 = 44 by decomposing numbers to add and make a new 10.
