Given (11,6)
and (x,−9)
, find all x
such that the distance between these two points is 17
. Separate multiple answers with a comma.
Therefore, the values of x that make the equation distance between (11,6) and (x,-9) equal to 17 are x = 19 and x = 3.
What exactly is a linear equation?The formula y=mx+b is used to draw a simple regression graph. The inclination is B, and the y-intercept is m. It is frequently referred to simply as a "simple method combining many variables," despite the fact that the section before it is divided into distinct sections. Bivariate linear equations have two variables. For problems involving linear equations in applications, there are no proven solutions. Y=mx+b, also known as mx+b, provides a number of straightforward formulae.
Here,
Using the distance formula:
sqrt((x - 11)^2 + (-9 - 6)^2) = 17
Simplifying:
sqrt((x - 11)^2 + 225) = 17
Squaring both sides:
(x - 11)^2 + 225 = 289
(x - 11)^2 = 64
Taking the square root:
x - 11 = ±8
x = 11 + 8 or x = 11 - 8
x = 19 or x = 3
Therefore, the values of x that make the equation distance between (11,6) and (x,-9) equal to 17 are x = 19 and x = 3.

If you want to estimate the mean height of all the .students at a university, which one of the following sampling strategies would be best? Why? Note that none of the methods are true simple random samplesi. Measure the heights of 50 students found in the gym during basketball intramurals ii. Measure the heights of all engineering majors. iii. Measure the heights of the students selected by choosing the first name on each page of the cam pus phone book.
The optimum sampling strategy is (iii), which is listed below.
By selecting a student's initial name from each page of the cam pus phone book, you may measure the heights of the chosen pupils.
What is Sampling?Sampling is a technique for selecting a small group of people or a subset of the population in order to make generalizations and estimate the features of the population. In order to acquire relevant information without studying the entire society, researchers commonly use a variety of sampling approaches in market research.
To ascertain the average height of all students at a certain institution and guarantee that the result is statistically reliable, the sampling process must be applied.
a. Measure the heights of 50 students found in the gym during basketball intramurals.
This approach is not ideal since you would only sample basketball players while leaving all other university students out; hence, your sample would not be representative of all students, simply those who play basketball.
b. Measure the heights of all engineering majors.
This approach is flawed since the sample exclusively includes engineering majors, leaving out students studying other courses.
c. Measure the heights of the students selected by choosing the first name on each page of the campus phone book.
This strategy, which is the finest of the three, allows you to select students independent of the sport or subject they are pursuing. It is more representative of the university student population.

h
3) Solve the system of equations.
2x + y = 8
-4x + 2y = 13
The average rate of change of the function is zero, the difference quotient is 6x + 3h - 1 and the value of (x, y) are (3/8, 29/4).
What is the average rate of change of the function1.
The function f(x) = x² - x² + 3 is a constant function, since the two terms x² - x² cancel out. Therefore, the average rate of change of f(x) on the interval [0,2] is zero, since the function has the same value (3) at both endpoints.
2.
The difference quotient for the function f(x) = 3x² - x + 4 is:
(f(x+h) - f(x)) / h
= ((3(x+h)² - (x+h) + 4) - (3x² - x + 4)) / h
= (3x² + 6xh + 3h² - x - h + 4 - 3x² + x - 4) / h
= (6xh + 3h² - h) / h
= 6x + 3h - 1
3.
To solve the system of equations:
2x + y = 8
-4x + 2y = 13
We can use either substitution or elimination method. Here we'll use the elimination method:
Multiplying the first equation by 2, we get:
4x + 2y = 16
Adding this equation to the second equation, we eliminate y and get:
4x + 2y - 4x + 2y = 16 + 13
4y = 29
y = 29/4
Substituting y = 29/4 into the first equation, we get:
2x + 29/4 = 8
2x = 8 - 29/4
2x = 3/4
x = 3/8
Therefore, the solution to the system of equations is (x,y) = (3/8, 29/4).

the rate at which a particular animal grows is proportional to the difference between its adult height and current height
The rate at which a particular animal grows is proportional to the difference between its adult height and current height. As the animal grows, the difference between the adult height and current height decreases. T
Therefore the rate of growth decreases. This is because, as the animal grows, it reaches a point where it cannot grow any taller and the rate of growth slows down. In other words, the rate of growth is proportional to the difference between the adult's height and current height. the rate of growth is also related to the age of the animal.
Younger animals tend to grow faster than older animals because their adult height is still far away, so the difference between their current height and adult height is greater.As the animal gets older and closer to its adult height, the rate of growth decreases.
furthermore, the rate of growth is also affected by the animal's diet and overall health. If the animal is malnourished or unhealthy, then its rate of growth will be slower than if it had a healthy diet and lifestyle. In conclusion, the rate of growth of a particular animal is proportional to the difference between its adult height and current height

The sum of the angles of a triangle is 180". One angle of a triangle 100% and the magnitude of the other two is in the ratio 2:3. Determine the magnitudes of the other two angles.
Answer:
The two angles are 32 degrees and 48 degrees.
Step-by-step explanation:
If one angle of a triangle is 100 degrees, then the sum of the other two angles is 80 degrees (180 - 100). If the magnitude of the other two angles is in the ratio 2:3, then we can call the first angle 2x and the second angle 3x. The sum of these two angles is 5x, so 5x = 80, and x = 16. So, the two angles are 2x = 32 degrees and 3x = 48 degrees.

The frequency of the wave is f = 0.67 hertz.
What is the frequency?
Frequency is the number of occurrences of a repeating event per unit of time.
1) The velocity of the wave can be calculated using the formula v = lambda / T, where lambda is the wavelength and T is the time period.
From the wave function, the wavelength can be determined by finding the distance between consecutive crests or troughs of the wave,
which is given by
2 * π / (5 * π / 6) = (2/5) * (6/π) m.
The time period can be determined by finding the time it takes for one complete wave cycle to occur, which is given by 2*π / (3 * π / 7) = (2/3) * (7/π) s.
So, the velocity of the wave is v = (2/5) * (6/π) m / ((2/3) * (7/π) s) = (12/15) * (6/7) * (π/π) m/s = 4/5 m/s.
2) The time period of the wave can be calculated as T = 2*π / (3 * π / 7) = (2/3) * (7/π) s.
3) The wavelength of the wave can be calculated as lambda = 2*π / (5 * π / 6) = (2/5) * (6/π) m.
4) The frequency of the wave can be calculated using the formula f = 1 / T, where T is the time period.
f = 1 / ((2/3) * (7/π) s) = (3/2) * (π/7) Hz
f = 0.67 hertz
Hence, the frequency of the wave is f = 0.67 hertz.

Give a brief account on wave function?A wave function, in physics, is a mathematical description of a wave, usually used in quantum mechanics to describe the behavior of subatomic particles such as electrons and protons. The wave function provides information about the position, momentum, and other properties of a particle at a given point in time and space. It is represented by a complex mathematical function that satisfies Schrödinger's equation, which describes the time evolution of a wave function in a quantum system. The wave function is central to the interpretation of quantum mechanics and is often used to calculate the probabilities of different outcomes in quantum experiments.
Given the wave function:
y(x, t) = 0.75 m × sin[(5 × π / 6 m⁻¹) × x - (3 × π / 7 s⁻¹) × t + π / 5]
The velocity of the wave can be calculated using the wavelength (λ) and frequency (f) of the wave. The velocity (v) is given by v = λ × f. The wavelength (λ) and frequency (f) can be determined from the wave function as follows:
λ = 2 × π / (5 × π / 6 m⁻¹) = 6 / 5 m
f = 3 × π / 7 s⁻¹
So, the velocity of the wave is given by:
v = λ × f = (6 / 5 m) × (3 × π / 7 s⁻¹) = (6 × 3 × π / (5 × 7)) m/s = (6 × π / 35) m/s
The time period (T) of the wave is the time it takes for the wave to complete one full cycle. It can be determined from the frequency of the wave as follows:
T = 1 / f = 1 / (3 × π / 7 s⁻¹) = 7 / (3 × π) s
The wavelength (λ) of the wave has already been calculated in step 1 as λ = 6 / 5 m
The frequency (f) of the wave has already been calculated in step 1 as f = 3 × π / 7 s⁻¹
So, the velocity of the wave is (6 × π / 35) m/s, the time period of the wave is 7 / (3 × π) s, the wavelength of the wave is 6 / 5 m, and the frequency of the wave is 3 × π / 7 s⁻¹.

Mpg = 37 miles per gallon.
How to get the miles per gallon?It is just given by the quotient between the number of miles traveled and the number of gallons used.
We know that at the start the odometer reads 69247 miles and at the end the odometer reads 69765 miles, taking the difference we can see that the total distance traveled is:
69765 mi - 69247 mi = 518 mi
And you consumed 14 gallons of gas, then the miles per gallon is:
Mpg = 518mi/14 gal = 37 miles per gallon.

Simplify
4x^3 - 12x^2
4x^2 + 7x - 2
2x^2 -6x
5x^2 + 11x + 2
2x(5x + 1) / (4x - 1) is the final expression.
Option D is the correct answer.
What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
(4x³ - 12x²) / (4x² + 7x - 2) / (2x² - 6x) / (5x² + 11x + 2)
= (4x³ - 12x²) x (5x² + 11x + 2) / (4x² + 7x - 2) x (2x² - 6x)
Now,
(4x³ - 12x²) = 4x² (x - 3) _____(1)
And,
(5x² + 11x + 2)
Middle term factorizing
= 5x² + (10 + 1)x + 2
= 5x² + 10x + x + 2
= 5x (x + 2) + 1(x + 2)
= (x + 2) (5x + 1) ______(2)
And,
(4x² + 7x - 2)
Middle term factorizing
= 4x² + (8 - 1)x - 2
= 4x² + 8x - x - 2
= 4x(x + 2) - 1(x + 2)
= (4x - 1) (x + 2) ______(3)
And,
(2x² - 6x) = 2x (x - 3) ______(4)
From (1), (2), (3), and (4) we get,
(4x³ - 12x²) x (5x² + 11x + 2) / (4x² + 7x - 2) x (2x² - 6x)
= [ 4x² (x - 3) x (x + 2) (5x + 1) ] / [ (4x - 1) (x + 2) x 2x(x - 3) ]
(x + 2) and (x - 3) gets canceled.
= [4x² (5x + 1)] / [(4x - 1) 2x]
= 2x(5x + 1) / (4x - 1)
Thus,
2x(5x + 1) / (4x - 1)

is the following statement true or false? all other things being equal, outliers tend to have a greater effect on the value of the mean, as compared to the value of the median.
All other things being equal, outliers tend to have a greater effect on the value of the mean, as compared to the value of the median. The given statement is true.
What is the mean and median?
Outliers are values that are significantly different from the other values in a data set, and their presence can greatly affect the value of measures of central tendency, such as the mean and the median.
The mean is a measure of central tendency that is calculated as the sum of all the values in a data set divided by the number of values. The presence of outliers can greatly affect the mean because outliers can have a large impact on the sum of the values in the data set. For example, if a data set has a few very large outliers, the mean will be pulled up to be much higher than the median, which represents the midpoint of the data set.
On the other hand, the median is a measure of central tendency that is calculated as the middle value of a data set when the values are arranged in order. The median is not as sensitive to outliers as the mean because outliers do not affect the median unless the number of outliers is so large that it changes the value of the middle value.
Hence, all other things being equal, outliers tend to have a greater effect on the value of the mean than on the value of the median.
