the value of p is 3/2, the value of q is 3t, and the value of r is 2/9.with the sum of the first n terms of the arithmetic series formula we are able to solve it
what is arithmetic series ?
An arithmetic series is a series of numbers in which each term is obtained by adding a fixed number to the preceding term (known as the common difference). The sum of the terms in an arithmetic series can be found by multiplying the average of the first and last
In the given question,
We know that the first term of the arithmetic series is given by (2t+1) and the common difference is 3. Therefore, the nth term can be written as:
a_n = a_1 + (n-1)d
(14r - 5) = (2t + 1) + (n-1)3
14r - 5 = 2t + 1 + 3n - 3
14r - 4 = 2t + 3n
7r - 2 = t + (3/2)n --------(1)
Now, we need to find the values of p, q, and r for the sum of the first n terms of the series, which is given by:
S_n = (n/2)[2a_1 + (n-1)d]
S_n = (n/2)[2(2t+1) + (n-1)3]
S_n = n(3n+4t+2)/2
We can simplify this expression by factoring out a 2 from the numerator:
S_n = n(3n+4t+2)/2 = (2n/2)(3n+4t+2)/2
S_n = (n/2)(3n+4t+2) = (3/2)n² + 2tn + n
Now, we need to write this expression in the form p(qt-1). To do this, we need to factor out (3/2):
S_n = (3/2)(n² + 4/3 tn + 2/3 n)
S_n = (3/2)[n² + 4/3 tn + (2/9)(3n)]
S_n = (3/2)[(n + (2/3)t)² - (4/9)t² + (2/9)n]
S_n = (3/2)[(n + (2/3)t)² - (4/9)t² + (2/9)n + (4/9)t² - (4/3)tn + (4/3)tn]
S_n = (3/2)[(n + (2/3)t)² - (4/9)t² + (2/9)n + (4/3)tn]
S_n = (3/2)[(n + (2/3)t)² - (4/9)t² + (2/9)(3t*n)]
Now we can see that p=3/2, q=3t, and r=2/9. Therefore, the value of p is 3/2, the value of q is 3t, and the value of r is 2/9.

n is inversely proportional to d²
n = 5 when d = 12
What is the value of n when d = 3?
Give answer to 1 d. p
Answer:
80
Step-by-step explanation:
To find the value of n when d = 3, we can use the given inverse proportionality relationship between n and d²:
n ∝ 1/d²
This can also be written as:
n = k / d²
where k is a constant of proportionality.
We are given that n = 5 when d = 12. Plugging in these values into the equation, we get:
5 = k / 12²
To solve for k, we can multiply both sides of the equation by 12²:
5 * 12² = k
k = 720
Now that we have the value of k, we can use it to find the value of n when d = 3:
n = k / d²
n = 720 / 3²
n = 720 / 9
n = 80
So, the value of n when d = 3 is 80.

The median of a data set is 18. What number is missing in the set of numbers of 12 17 21 13 and 25
The missing number in the set is 19 when the median of a data set is given which is 18.
What is the median?The median is a measure of central tendency in statistics that represents the middle value of a data set when the values are arranged in order from lowest to highest (or highest to lowest). It is the value that separates the lower 50% of the data from the upper 50% of the data.
According to the given informationTo find the missing number, we can first rearrange the given numbers in order from smallest to largest:
12, 13, 17, ___, 21, 25
Since the median of the data set is 18, we know that it is the middle value when the numbers are arranged in order. In this case, there are five numbers, so the median is the third number. Therefore, we have:
12, 13, 17, ___, 21, 25
The missing number must be between 17 and 21 in order for 18 to be the median. We can take the average of these two numbers to find the missing value:
(17 + 21) / 2 = 19

A right triangle, also known as a right-angled triangle, right-perpendicular triangle, orthogonal triangle, or formerly rectangle triangle, is a triangle with one right angle, or two perpendicular sides. The foundation of trigonometry is the relationship between the sides and various angles of the right triangle.
Here, we have
Given: the points A, B, and C have the coordinates A (5, 2), B (2, -3), and C (-8, 3).
We have to show that the triangle ABC is a right-angled triangle.
Now, we find the vectors of AB, BC & AC:
AB = (2-5)i+(-3-2)j = -3i-5j
BC = (-8-2)i+(3-(-3))j = -10i+6j
AC = (-8-5)i+(3-2)j = -13i+j
Now if the dot product of two of these vectors results in zero, it means that those vectors (representing the triangle sides) are perpendicular to each other (which means triangle ABC is a right-angled triangle)

the value of p is 3/2, the value of q is 3t, and the value of r is 2/9.with the sum of the first n terms of the arithmetic series formula we are able to solve it
what is arithmetic series ?
An arithmetic series is a series of numbers in which each term is obtained by adding a fixed number to the preceding term (known as the common difference). The sum of the terms in an arithmetic series can be found by multiplying the average of the first and last
In the given question,
We know that the first term of the arithmetic series is given by (2t+1) and the common difference is 3. Therefore, the nth term can be written as:
aₙ = a_1 + (n-1)d
(14r - 5) = (2t + 1) + (n-1)3
14r - 5 = 2t + 1 + 3n - 3
14r - 4 = 2t + 3n
7r - 2 = t + (3/2)n --------(1)
Now, we need to find the values of p, q, and r for the sum of the first n terms of the series, which is given by:
Sₙ = (n/2)[2a_1 + (n-1)d]
Sₙ = (n/2)[2(2t+1) + (n-1)3]
Sₙ = n(3n+4t+2)/2
We can simplify this expression by factoring out a 2 from the numerator:
Sₙ = n(3n+4t+2)/2 = (2n/2)(3n+4t+2)/2
Sₙ = (n/2)(3n+4t+2) = (3/2)n² + 2tn + n
Now, we need to write this expression in the form p(qt-1). To do this, we need to factor out (3/2):
Sₙ = (3/2)(n² + 4/3 tₙ + 2/3 n)
Sₙ = (3/2)[n² + 4/3 tₙ + (2/9)(3n)]
Sₙ = (3/2)[(n + (2/3)t)² - (4/9)t² + (2/9)n]
Sₙ = (3/2)[(n + (2/3)t)² - (4/9)t² + (2/9)n + (4/9)t² - (4/3)tₙ + (4/3)tₙ]
Sₙ = (3/2)[(n + (2/3)t)² - (4/9)t² + (2/9)n + (4/3)tₙ]
Sₙ = (3/2)[(n + (2/3)t)² - (4/9)t² + (2/9)(3t*n)]
Now we can see that p=3/2, q=3t, and r=2/9. Therefore, the value of p is 3/2, the value of q is 3t, and the value of r is 2/9.

The cost of buying different numbers of bagels is shown. Complete a true statement to describe the cost function.
The function is non-linear in the cost of buying different numbers of bagels shown.
What is non-linear function?A non-linear function is a mathematical function that doesn't follow a straight line or a constant rate of change. In other words, it's a function that does not have a constant slope. Non-linear functions are used in various fields such as physics, economics, engineering, and more. An example of a non-linear function is the quadratic function f(x) = x². As x increases, the rate of change of y increases as well, resulting in a curved graph. Non-linear functions can have different degrees, such as cubic or quartic functions, and they can be useful in modeling complex real-world phenomena where the relationship between variables is not linear.
Now
2.40 - 1.25 = 1.15
3.45 -2.40 = 1.05
so 1.15 ≠ 1.05
So the function is non-linear because there is not a constant rate of change.

The graph showsf(x)and its transformationg(x).
Enter the equation for g(x) in the box.
ANSWER: 2x+1
Answer: 2x + 1
Step-by-step explanation:
The graph of f(x) is a straight line passing through the points (0,1) and (3,4). The slope of this line is (4-1)/(3-0) = 1, and the y-intercept is 1.
The graph of g(x) is a transformation of f(x) obtained by shifting it 1 unit upwards and 1 unit to the left. Therefore, the equation for g(x) is:
g(x) = f(x+1) + 1
Substituting f(x) with its equation, we get:
g(x) = (x+1) + 1
Simplifying:
g(x) = 2x + 2
Finally, we can rewrite the equation of g(x) in the standard form as:
g(x) = 2x + 1
Therefore, the equation for g(x) is 2x+1.
Unfortunately, I cannot see the graph you are referring to. However, if the graph shows a linear function f(x) and its transformation g(x), and g(x) is obtained by shifting f(x) horizontally 1 unit to the left and vertically 1 unit upwards, then the equation for g(x) would be g(x) = f(x + 1) + 1. If f(x) is a linear function of the form f(x) = mx + b, then the equation for g(x) would be g(x) = m(x + 1) + b + 1, which simplifies to g(x) = mx + (m + 1). If you provide more information about the graph, I can help you find the equation for g(x).

the required annual interest rate, to the nearest tenth of a percent, is 10.1%
What is interest rate?The amount that a lender charges a borrower for the use of money is known as an interest rate, and it is often represented as a percentage of the principle amount (the amount borrowed). It is either the fee for borrowing money or the compensation for lending it.
To find the annual interest rate compounded monthly, we need to use the formula:
[tex]A = P(1 + r/12)^(12*n)[/tex]
where:
A = the final amount
P = the initial principal
r = the annual interest rate (as a decimal)
n = the number of years
In this case, we know that P = 923, A = 1540, n = 2 years, and interest is compounded monthly, which means that there are 12 compounding periods per year.
We can use logarithms to solve for r:
[tex]A = P(1 + r/12)^(12n)[/tex]
[tex]1540 = 923(1 + r/12)^(122)[/tex]
[tex]1540/923 = (1 + r/12)^24[/tex]
[tex]ln(1540/923) = 24 ln(1 + r/12)[/tex]
[tex]ln(1540/923)/24 = ln(1 + r/12)[/tex]
[tex]e^(ln(1540/923)/24) - 1 = r/12[/tex]
[tex]r = 12(e^(ln(1540/923)/24) - 1)[/tex]
Using a calculator, we find that:
r ≈ 0.1009
So the required annual interest rate, to the nearest tenth of a percent, is 10.1%.

A point is moving on the graph of xy = 3. When the point is at (1, 3), its x-coordinate is increasing at a rate of 4 units per second. What is the speed of the y-coordinate at that moment and in which direction is it moving?
The speed of the y-coordinate at that moment is 12 units per second, and it is moving in the negative y-direction.
What is a graph?
In computer science and mathematics, a graph is a collection of vertices (also known as nodes or points) connected by edges (also known as links or lines).
We can start by taking the derivative of the equation xy = 3 with respect to time t:
x(dy/dt) + y(dx/dt) = 0
Now we can substitute the given information: when the point is at (1, 3), dx/dt = 4. Solving for dy/dt:
(1)(dy/dt) + (3)(4) = 0
dy/dt = -12/1 = -12 units per second
The negative sign indicates that the y-coordinate is decreasing.
So the speed of the y-coordinate at that moment is 12 units per second, and it is moving in the negative y-direction.

The first three terms of a geometric sequence are as follows.
-5, -10, -20
Find the next two terms of this sequence.
Give exact values (not decimal approximations).
Answer: The common ratio (r) of a geometric sequence can be found by dividing any term by its preceding term. Let's use the first two terms of the sequence:
r = (-10) / (-5) = 2
Now that we know the common ratio, we can find the next two terms:
The fourth term:
a4 = ar^3 = (-5)(2)^3 = -40
The fifth term:
a5 = ar^4 = (-5)(2)^4 = -80
Therefore, the next two terms of the sequence are -40 and -80, respectively.

Step-by-step explanation: Number of water bottles in March = 4,100 + 7% of 4,100
= 4,100 + 287
= 4,387
Number of water bottles in April = 4,387 + 500
= 4,887
Percent increase from February to April = ((4,887 - 4,100) / 4,100) x 100%
= (787 / 4,100) x 100%
= 19.19%
Therefore, the percent increase in the number of water bottles the company manufactured from February to April is approximately 19%.
