The equation y² - y²x = 6 can be describe as a function of x as:
y = √(6/(x - x)).
What is a function?A function is a relationship between inputs where each input is related to exactly one output.
Example:
f(x) = 2x + 1
f(1) = 2 + 1 = 3
f(2) = 2 x 2 + 1 = 4 + 1 = 5
The outputs of the functions are 3 and 5
The inputs of the function are 1 and 2.
We have,
y² - y²x = 6
Taking y² as common.
y²(1 - x) = 6
Divide both sides with (1 - x).
y² = 6/(1 - x)
Square root on both sides.
y = √(6/(x - x))
This is a function of x.
Thus,
y = √(6/(x - x)) is a function of x.

Brigitte deposits $1000 in a savings account that earns 1.3% compound interest. Which function models the total amount of money Brigitte has over time, t ?
The formula for compound interest is:
A = P(1 + r/n)^nt
where:
A is the total amount of money after t years,
P is the initial principal or deposit amount (in this case $1000),
r is the annual interest rate as a decimal (in this case 1.3% or 0.013),
n is the number of times interest is compounded per year (in this case, let's assume it's compounded annually), and
t is the number of years.
So, the function modeling the total amount of money Brigitte has over time, t, would be:
A = $1000(1 + 0.013)^t
This function shows how the amount of money in the savings account will increase as time goes on due to compound interest.

If you toss 9 fair coins, in how many ways can you obtain at least two tails?
("At least two" is the complement of "zero or one.")
There are different ways of obtaining at least two tails.
(Type a whole number.)
There is 1 way to obtain at least two tails when you toss 9 fair coins.
What is the probability?
Probability is simply how likely something is to happen. Whenever we're unsure about the outcome of an event, we can talk about the probabilities of certain outcomes—how likely they are. The analysis of events governed by probability is called statistics.
If you toss 9 fair coins, there are 2⁹ = 512 possible outcomes.
The number of ways to obtain zero or one tail is equal to the number of ways to obtain all heads or one head and the rest of tails, which is 2⁹ - 1 = 511.
Therefore, the number of ways to obtain at least two tails is the complement of the number of ways to obtain zero or one tail, which is 512 - 511 = 1.
Therefore, there is 1 way to obtain at least two tails when you toss 9 fair coins.

the equation of a curve is given by
y=x^3/3+7x^2/2+10x+d, where d is a
constant. Find the possible values of d
when the x-axis is tangent to the curve
v=x^3/3+7x^2/2+10x+d.
Answer: The x-axis is tangent to the curve when the value of y is equal to 0. So, to find the possible values of d when the x-axis is tangent to the curve, we need to solve the equation:
x^3/3 + 7x^2/2 + 10x + d = 0
To solve this equation, we need to use a method such as the cubic formula or a numerical method such as Newton-Raphson. However, it is not possible to determine a general solution for d without additional information, such as the value of x at which the tangency occurs. The possible values of d will depend on the specific value of x that satisfies the equation.

The rectangle is framed find the area of shaded region if the frame is 2 unit wide
The area of the shaded region is 20 square units for the given rectangle frame.
What is the area of the rectangle?The area of a rectangle is defined as the product of the length and width.
The area of a rectangle = L × W
Where W is the width of the rectangle and L is the length of the rectangle
Dimensions of the inside rectangle, are as follows:
Length L₁ = 5 units
Width W₁ = 3 units
Since the frame is 2 units wide,
So, the dimensions of the outside rectangle, are as follows:
Length L₂ = 5 + 2 = 7 units
Width W₂ = 3 + 2 = 5 units
The area of the shaded region = area of the outside rectangle - area of the inside rectangle
The area of the shaded region = L₂ x W₂ - L₁ x W₁
The area of the shaded region = 7 x 5 - 5 x 3
The area of the shaded region = 35 - 15
The area of the shaded region = 20 square units
Thus, the area of the shaded region is 20 square units.

The question seems incomplete, the missing figure is attached below.
Solve the quadratic equation by the square root method and write the solutions in radical form. Simplify the solutions.
(3x+20)2=125
Answer:
Step-by-step explanation:
To solve the equation (3x + 20)^2 = 125 using the square root method, we start by taking the square root of both sides:
√[(3x + 20)^2] = √125
3x + 20 = ± 5
Next, we subtract 20 from both sides:
3x = -20 ± 5
Finally, we divide both sides by 3:
x = -8 or x = 3/3
So, the two solutions to the equation (3x + 20)^2 = 125 are x = -8 and x = 1. These solutions are in radical form and are already simplified.
The time between arrivals of customers at a bank during the noon-to-1 p.m. hour has a uniform distribution between 0 to 120 seconds. What is the probability that the time between the arrival of two customers will be
a. less than 20 seconds?
b. between 10 and 30 seconds?
c. more than 35 seconds?
d. What are the mean and standard deviation of the time between arrivals?
Answer:
Step-by-step explanation:
Here's a step-by-step solution to finding the probabilities of the time between customer arrivals:
a. less than 20 seconds:
To find the probability that the time between arrivals is less than 20 seconds, we need to find the cumulative distribution function (CDF) of the time between arrivals and evaluate it at 20 seconds. The CDF for a uniform distribution is given by:
F(x) = x/b - a/b, where a is the lower bound and b is the upper bound of the distribution
For this problem, the lower bound a is 0 and the upper bound b is 120, so the CDF of the time between arrivals is:
F(x) = x/120
Now, we can evaluate the CDF at 20 seconds to find the probability that the time between arrivals is less than 20 seconds:
F(20) = 20/120 = 1/6
So, the probability that the time between arrivals is less than 20 seconds is 1/6.
b. between 10 and 30 seconds:
To find the probability that the time between arrivals is between 10 and 30 seconds, we need to find the difference between the CDFs at 30 seconds and 10 seconds:
F(30) - F(10) = 30/120 - 10/120 = 3/12 - 1/12 = 2/12 = 1/6
So, the probability that the time between arrivals is between 10 and 30 seconds is 1/6.
c. more than 35 seconds:
To find the probability that the time between arrivals is more than 35 seconds, we need to subtract the CDF at 35 seconds from 1:
1 - F(35) = 1 - 35/120 = 85/120 = 7/12
So, the probability that the time between arrivals is more than 35 seconds is 7/12.
d. Mean and standard deviation:
The mean of the time between arrivals is given by the average of the lower and upper bounds of the distribution:
mean = (a + b)/2 = (0 + 120)/2 = 60
The standard deviation of the time between arrivals for a uniform distribution is given by:
standard deviation = (b - a)/(2 * sqrt(3))
For this problem, the standard deviation is:
standard deviation = (120 - 0)/(2 * sqrt(3)) = 60/sqrt(3) ≈ 34.64101615
So, the mean time between arrivals is 60 seconds and the standard deviation is approximately 34.64 seconds.
a. The less than 20 seconds 0.1667.
b. The between 10 and 30 seconds 0.1667.
c. The more than 35 seconds 0.7083.
d. The mean and standard deviation of the time between arrivals 34.64 seconds.
To solve the probability questions, to find the probability density function (PDF) of the uniform distribution for the time between customer arrivals. In a uniform distribution, the probability density is constant within the given range.
Given:
Time between arrivals follows a uniform distribution between 0 to 120 seconds.
a. Probability of time between arrivals being less than 20 seconds:
Since the probability density is constant within the given range, we can calculate the probability by dividing the time range of interest (20 seconds) by the total time range (120 seconds).
Probability = (Time of interest) / (Total time range) = 20 / 120 = 1/6 ≈ 0.1667
b. Probability of time between arrivals being between 10 and 30 seconds:
Similar to part (a), the probability for this interval can be found by dividing the time range of interest (30 - 10 = 20 seconds) by the total time range (120 seconds).
Probability = (Time of interest) / (Total time range) = 20 / 120 = 1/6 ≈ 0.1667
c. Probability of time between arrivals being more than 35 seconds:
In this case, we need to calculate the probability of the time between arrivals being in the range from 35 to 120 seconds (as it is more than 35 seconds).
Probability = (Time of interest) / (Total time range) = (120 - 35) / 120 = 85 / 120 ≈ 0.7083
d. Mean and standard deviation of the time between arrivals:
In a uniform distribution, the mean (μ) can be calculated as the average of the minimum and maximum values in the range.
Mean (μ) = (Minimum value + Maximum value) / 2 = (0 + 120) / 2 = 60 seconds
The standard deviation (σ) for a uniform distribution can be calculated using the formula:
Standard deviation (σ) = (Maximum value - Minimum value) / √12
Standard deviation (σ) = (120 - 0) / √12 ≈ 34.64 seconds
So, the mean time between arrivals is 60 seconds, and the standard deviation is approximately 34.64 seconds.

Write a system of equations that can be used to determine s, the number of small chairs and T, the numbers large chairs, the designer makes. How many small chairs did the designer make?
After solving the system of equations, we found that the number of small chairs is 53 and the number of large chairs is 45.
What is meant by the system of equations?
A set of equations with a finite number of solutions is referred to as a system of equations. A system of equations in algebra consists of two or more equations and looks for common answers to the equations. A group of equations that are all satisfied by the same set of variables are referred to as a system of linear equations.
Given,
Cost of material for small chair = $10
Cost of material for large chair = $15
The selling price for a small chair = $22
The selling price for a large chair = $51
The total money spent on materials = $305
Designer makes 8 more small chairs than large chairs.
If the number of large chairs = t and the number of small chairs = s
Using the given equations, we can write the following system of equations.
10s + 15t = 305
s - t = 8
Now we make the coefficient of s in both equations the same.
Multiply 10 in the second equation.
10s + 15t = 305
10s - 10t = 80
Subtracting,
5t = 225
t = 45
s = 8 + t = 45 + 8 = 53
Therefore after solving the system of equations, we found that the number of small chairs is 53 and the number of large chairs is 45.

Tony can afford the car insurance, and he has enough money( $426.33 ) left over each month to cover other expenses.
To determine if Tony can afford the car insurance
We need to calculate the cost of the insurance and compare it to his monthly pay.
According to the information given,
Tony's yearly pay is $8,320
and his monthly pay is $693.
If we round his yearly pay to $8,000, his monthly car insurance will be 1/30 of that amount, or $266.67.

a circle graph titled preferred music, with five sections labeled rock 13 percent, hip hop 25 percent, pop 35 percent, classical 13 percent, and jazz 14 percent
Which of the following conclusions can we draw from the circle graph?
Hip Hop is the preferred music for 25 students.
Together, Pop and Jazz are the preferred music for over half the students.
Classical is the preferred music for 52 students.
Together, Rock and Hip Hop are the preferred music for 172 students.
The correct conclusion from the given percentage of students of different categories is option(c): Classical is the preferred music for 52 students.
What is meant by percentage?
A figure or ratio stated as a fraction of 100 is called a percentage. It is frequently indicated by the percent sign, "%."
Given,
Total number of middle school students = 400
Percent of students who prefer rock = 13%
Percent of students who prefer hip hop = 25%
Percent of students who prefer pop = 35%
Percent of students who prefer classical = 13%
Percent of students who prefer jazz = 14%
Now we can find the number of students for each category.
Number of students who prefer rock = 13/100 * 400 = 52
Number of students who prefer hip hop = 0.25 * 400 = 100
Number of students who prefer pop = 0.35 * 400 = 140
Number of students who prefer classical = 0.13 * 400 = 52
Number of students who prefer jazz = 0.14 * 400 = 56
We can now look at different options.
a) This is false as hip-hop is preferred by 100 students.
b) Together Pop and jazz are preferred by 140+56 = 196, which is not more than half (200) of students. So this is false.
c) This is true as classical is preferred by 52 students.
d) Together rock and hip hop are preferred by 52+100 = 152, which is not equal to 172. So this is false.
Therefore the correct conclusion from the given percentage of students of different categories is option(c).

4x³ + cx² + x + 2 ÷ x + 2 = ...
first we divide
4x³ + cx² by x + 2
and that is by doing 4x³/x = 4x².
4x³ + cx² + x + 2 ÷ x + 2 = 4x² ...
now we need to find the remainder, as with regular number divisions :
4x² × (x + 2) = 4x³ + 8x²
which we need to subtract from the left side
4x³ + cx² + x + 2 ÷ x + 2 = 4x² ...
- 4x³ + 8x²
----------------
0 cx² - 8x²
now we pull down the next position (x) and divide that by x + 2
4x³ + cx² + x + 2 ÷ x + 2 = 4x² + 1
- 4x³ + 8x²
----------------
0 cx² - 8x² + x
and the same again, to find the remainder, we have to subtract 1×(x + 2) = x + 2 from the left side
4x³ + cx² + x + 2 ÷ x + 2 = 4x² ...
- 4x³ + 8x²
----------------
0 cx² - 8x² + x
- x + 2
-----------------------------
cx² - 8x² 0 0
the polynomial is divisible by x + 2, if the remainder is 0.
so,
cx² - 8x² = 0
cx² = 8x²
c = 8

The value of the segment in the geometry of the triangle is 17.5.
What is triangle?A triangle is a sort of polygon with three sides, as was said in the introduction. The vertex of a triangle is where two of its sides meet at an angle. There is an angle created between two sides. One of the crucial elements of geometry is this.
Certain fundamental ideas, including the Pythagorean theorem and trigonometry, rely on the characteristics of triangles. The angles and sides of a triangle determine its kind.
If a line is parallel to one side of the triangle and intersects the other two sides, then it divides the side into segments of proportional length.
Thus,
12 / (12 + 14) = 15 / (15 + x)
12(15 + x) = 15(26)
180 + 12x = 390
12x = 210
x = 17.5
Hence, the value of the segment in the geometry of the triangle is 17.5.

In 1999 there were 60 million people worldwide who had been infected with a particular disease. At that time the infection rate was 3.5 million people per year.
(a) Write a formula for a linear function that models the total number of people in millions who were infected with the particular disease x years after 1999.
(b) Estimate the number of people who may have been infected by the year 2013.
f(x) = ax + b, where a and b are real values, is the formula for a linear function. In this instance, a denotes the line's gradient, and b denotes the y-axis intercept (which is sometimes called the vertical intercept).
What is linear function?A straight line makes up the graph of a linear function. The following expression describes a linear function. Y equals f(x) = a + bx. Both the independent and dependent variables of a linear function are one. Any function that depicts a straight line on the coordinate plane is said to be linear. For instance, the equation y = 3x – 2 indicates a straight line on a coordinate plane, indicating that it is a linear function. This function can be expressed as f(x) = 3x - 2 since f(x) can take the place of y. Look for a steady rate of change to determine whether a table of values depicts a linear function. You are viewing a linear function if there is one!To learn more about linear function, refer to:

A company acquires equipment at a cost of $32,900 on January 3, 2004. Management estimates the equipment will have a residual value of $4,700 at the end of its 4-year useful life. Assume that the company uses the diminishing-balance method and that the diminishing-balance depreciation rate is double the straight-line rate. Calculate the depreciation expense for each year of the equipment’s life.
Answer:
Step-by-step explanation:
To calculate the depreciation expense for each year of the equipment's life using the diminishing-balance method, we need to first find the straight-line rate, and then find the diminishing-balance rate by doubling the straight-line rate.
Step 1: Calculate the straight-line rate
The straight-line rate can be calculated as follows:
SLR = (Cost - Residual Value) / Useful Life
SLR = (32900 - 4700) / 4
SLR = $27,600 / 4
SLR = $6,900 per year
Step 2: Calculate the diminishing-balance rate
The diminishing-balance rate can be calculated as follows:
DBR = 2 * SLR
DBR = 2 * $6,900
DBR = $13,800
Step 3: Calculate the depreciation expense for each year
The depreciation expense for each year can be calculated as follows:
Year 1: Depreciation Expense = Cost * (DBR / 2)
Year 1: Depreciation Expense = $32,900 * ($13,800 / 2)
Year 1: Depreciation Expense = $32,900 * $6,900
Year 1: Depreciation Expense = $227,621
Year 2: Depreciation Expense = (Cost - Year 1 Depreciation) * (DBR / 2)
Year 2: Depreciation Expense = ($32,900 - $22,761) * ($13,800 / 2)
Year 2: Depreciation Expense = $10,139 * $6,900
Year 2: Depreciation Expense = $70,223
Year 3: Depreciation Expense = (Cost - Year 1 Depreciation - Year 2 Depreciation) * (DBR / 2)
Year 3: Depreciation Expense = ($32,900 - $22,761 - $70,223) * ($13,800 / 2)
Year 3: Depreciation Expense = $10,016 * $6,900
Year 3: Depreciation Expense = $68,609
Year 4: Depreciation Expense = (Cost - Year 1 Depreciation - Year 2 Depreciation - Year 3 Depreciation) * (DBR / 2)
Year 4: Depreciation Expense = ($32,900 - $22,761 - $70,223 - $68,609) * ($13,800 / 2)
Year 4: Depreciation Expense = $21,307 * $6,900
Year 4: Depreciation Expense = $146,763
So, the depreciation expenses for each year of the equipment's life are:
Year 1: $22,761
Year 2: $70,223
Year 3: $68,609
Year 4: $146,763
This is how you can calculate the depreciation expense for each year of the equipment's life using the diminishing-balance method.

What does the graph show?The graph shows the way a toy rocket changes its height once it is launched. In general, it can be seen the height increases for some seconds and then the height decreases.
How to calculate the interval?To calculate the interval let's find out the second or minute at which the rocket loses height.
0 - 1 second (from this moment the rocket loses height)
Based on this, it can be concluded the interval is 0-1 seconds.
