The median of all possible values of x is 5.
What is Triangle?A triangle is a three-sided polygon that consists of three edges and three vertices.
To find the median of all possible values of x, we need to find all the possible values of x first.
By the triangle inequality, we know that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side. So, we can write:
2 + 5 > x
2 + x > 5
5 + x > 2
Simplifying each inequality, we get:
7 > x
x > 3
x > -3
The smallest possible integer value for x is 4 and the largest possible integer value for x is 6.
Therefore, the possible integer values for x are 4, 5, and 6.
Since we have an odd number of values, the median is simply the middle value, which is 5.
Therefore, the median of all possible values of x is 5.

Fill The Blank ?a function is a rule that assigns to each value of the_____
In essence, a function is a rule that assigns to each value of the input set (also known as the domain), a unique value of the output set (also known as the range).
A function is a fundamental mathematical concept that is used to describe the relationship between two sets of values.
To understand the idea of a function, imagine a machine that takes in an input and produces an output. The input values are the domain of the function, and the output values are the range. A function can be represented as an equation, a graph, or a table. For example, the equation f(x) = x + 3 represents a function that takes in an input value x and produces an output value that is 3 greater than the input value.
One of the key features of a function is that each input value must have a unique output value. This means that if you input the same value into the function twice, you should get the same output value both times. In mathematical terms, we say that a function is well-defined if it has a unique output value for each input value.
Functions are used in a wide range of mathematical applications, from algebra and calculus to statistics and data analysis. They provide a powerful tool for describing and analyzing relationships between different sets of values.

What is least common multiple ?
The least common multiple (LCM) of two or more numbers is the smallest number that is a multiple of all the given numbers. In other words, it is the smallest number that is divisible by all the given numbers without leaving a remainder.
To find the LCM of two or more numbers, you can list their multiples and look for the smallest number that appears in all the lists. However, this can become time-consuming for large numbers. There are various methods and algorithms to find the LCM efficiently, such as using prime factorization or the Euclidean algorithm.
According to the question:
Allergy Sufferer #1 takes 1 capsule every 6 hours, so in 45 capsules, they will need to take 45 * 6 = 270 hours.
Allergy Sufferer #2 takes 1 capsule every 12 hours, so in 45 capsules, they will need to take 45 * 12 = 540 hours.
To find the total time it will take them together to consume 45 capsules, we need to find the least common multiple (LCM) of 6 and 12.
The prime factors of 6 are 2 and 3.
The prime factors of 12 are 2, 2, and 3.
To find the LCM, we take the highest power of each prime factor that appears in either factorization. In this case, that's 2^2 * 3 = 12.
So, the LCM of 6 and 12 is 12.
This means that every 12 hours, Allergy Sufferer #1 will have taken 2 capsules (since 12/6=2), and Allergy Sufferer #2 will have taken 1 capsule.
Therefore, in 12 hours, they will have taken a total of 2+1=3 capsules.
So, to consume 45 capsules, it will take them 45/3 = 15 lots of 12 hours, which is 180 hours in total.

If point A
and point B
are located 12
feet apart and are both at ground level, what is the approximate height of the tree to the nearest foot?
feet
Answer:
44 ft
Step-by-step explanation:
You want to know the height of a tree whose top is at angles of elevation of 42° and 50° from points 12 feet apart.
TangentThe tangent of an angle is related to the side lengths of a right triangle by ...
Tan = Opposite/Adjacent
This tells us the length of the side adjacent to the angle of elevation is ...
Adjacent = Opposite/Tan
ApplicationHere, the height of the tree is the side of the triangle opposite the angle of elevation, and the difference of adjacent sides is 12 ft:
12 = h/tan(42°) -h/tan(50°)
h = 12/(1/tan(42°) -1/tan(50°)) ≈ 12/(1.11061 -0.83910) ≈ 44.197

How does the transformation of a function happen?The transformation of a function may involve any change.
Usually, these can be shifted horizontally (by transforming inputs) or vertically (by transforming output), stretched (multiplying outputs or inputs), etc.
If the original function is y = f(x), assuming the horizontal axis is the input axis and the vertical is for outputs, then:
Horizontal shift (also called phase shift):
Left shift by c units: y=f(x+c) (same output, but c units earlier)
Right shift by c units: y=f(x-c)(same output, but c units late)
Vertical shift:
Up by d units: y = f(x) + d
Down by d units: y = f(x) - d
Stretching:
Vertical stretch by a factor k: y = k × f(x)
Horizontal stretch by a factor k: y = f(x/k)
Given data ,
Let the parent function be represented as A
Now , the value of A is
f ( x ) = x or y = x
Now , when the function is reflected over the y-axis , the x coordinate of the function is changed to its additive inverse

A swimming pool whose volume is 10,000 gal contains water that is 0.01% chlorine. Starting at t= 0, city water containing 0.003% chlorine is pumped into the pool at a rate of 6 gal/min. The pool water flows out at the same rate. What is the percentage of chlorine in the pool after 1 hour? When will the pool water be 0.006% chlorine? What is the percentage of chlorine in the pool after 1 hour? After 1 hour the pool will be % chlorine. (Round to four decimal places as needed.)
The pool water will be 0.006% chlorine after approximately 236.5 minutes, and the percentage of chlorine in the pool after 1 hour (60 minutes) is approximately 0.674%.
Let C(t) be the amount of chlorine in the pool at time t in minutes, measured in gallons of chlorine. Since the volume of the pool is 10,000 gal and the initial concentration of chlorine is 0.01%, we have:
C(0) = 10,000 gal x 0.01% = 1 gal
As city water containing 0.003% chlorine is pumped into the pool at a rate of 6 gal/min and the pool water flows out at the same rate, the differential equation for C(t) is:
dC/dt = (0.003 - C(t)/10,000) x 6 - C(t)/10,000 x 6
Simplifying the right-hand side and solving the differential equation using separation of variables, we get:
C(t) = 30,000(1 - e^(-t/166.7)) - 180,000e^(-t/166.7)
After 1 hour (60 minutes), we have:
C(60) = 30,000(1 - e^(-60/166.7)) - 180,000e^(-60/166.7) ≈ 0.0674 gal
The percentage of chlorine in the pool after 1 hour is:
0.0674 gal / 10,000 gal x 100% ≈ 0.674%
To find when the pool water is 0.006% chlorine, we set C(t) = 10,000 gal x 0.006% = 0.6 gal and solve for t:
30,000(1 - e^(-t/166.7)) - 180,000e^(-t/166.7) = 0.6
Using numerical methods, we find that t ≈ 236.5 minutes.
After roughly 236.5 minutes, the chlorine content of the pool will be 0.006%, and after an hour (60 minutes), it will be approximately 0.674%.

The company plans to find the center of the data an give a 5% raise to the employees who have been employee for at least those number of years.Find the mean and median,and explain which will be better from the employees prescriptive.
Number of years of each employed {11,6,32,7,18,4,9,1,15,9,5,27}
The mean is 11.25 and median is 8, and from the employees' perspective, the median would be a better measure of central tendency to use for determining the raise cut-off point.
The mean and medianTo find the mean and median, we can start by arranging the data in ascending order:{1, 4, 5, 6, 7, 9, 9, 11, 15, 18, 27, 32}
Mean:The mean is the average value of the dataset. We can find the mean by summing up all the values and dividing by the total number of values:
mean = (1 + 4 + 5 + 6 + 7 + 9 + 9 + 11 + 15 + 18 + 27 + 32) / 12
= 135 / 12
= 11.25
Therefore, the mean of the dataset is 11.25.
Median:The median is the middle value in the dataset. If the dataset has an odd number of values, the median is the middle value. If the dataset has an even number of values, the median is the average of the two middle values.
In this case, the dataset has 12 values, so we need to find the average of the 6th and 7th values:
median = (7 + 9) / 2
= 8
Therefore, the median of the dataset is 8.
From the employees' perspective, the median would be a better measure of central tendency to use for determining the raise cutoff point. This is because the median is not affected by outliers as much as the mean.
In this dataset, the value of 32 is much larger than the other values and could skew the mean upward, which would result in a higher cutoff point for the raise. On the other hand, the median is not affected by the outlier and provides a better representation of the central value of the dataset.
A 5% raise for employees who have been employed for at least 8 years (the median) would be more fair and reasonable for all employees.

D) f(x) = (x − 1)(x − 2)(2x + 3)
Answer:
Step-by-step explanation:
If k=1 is a zero of f(x), then (x-1) is a factor of f(x) by the factor theorem. We can use polynomial long division or synthetic division to find the quotient when f(x) is divided by (x-1):
2 -3 -5 6

show that (x-3) is a factor of the polynomial h(x)=f(x)-f(3)
Answer:
To show that (x-3) is a factor of the polynomial h(x) = f(x) - f(3), we need to use the definition of a polynomial factor. A polynomial factor is a polynomial that, when multiplied by another polynomial, results in the original polynomial.
First, let's evaluate f(3) to find the value of h(3).
h(3) = f(3) - f(3) = 0
Now let's examine the value of h(x) for any x other than 3.
h(x) = f(x) - f(3)
If (x-3) is a factor of h(x), then for any value of x other than 3, h(x) should be equal to zero.
So,
h(x) = (x-3)g(x)
where g(x) is another polynomial.
Therefore, by definition, (x-3) is a factor of h(x) = f(x) - f(3).

A statement that increases numpeople by 5 is
numpeople = numpeople + 5
Here's a statement that increases the value of numpeople by 5:
numpeople = numpeople + 5
After executing this statement, the value of numpeople will be increased by 5. For example, if numpeople was initially 10, the value of numpeople would be 15 after executing this statement.
Here's a complete program that demonstrates the statement:
numpeople = 10
print("There are", numpeople, "people.")
numpeople = numpeople + 5
print("There are", numpeople, "people.")
