Write an explicit formula for an, the nth term of the sequence 26, 24, 22
we get that the nth term of the arithmetic sequence is given by aₙ = 28 - 2 n.
We are given an arithmetic sequence:
26, 24 , 22 ....
We need to find the nth term of this sequence (aₙ)
We will first find the common difference between the terms:
Common difference = d = 24 - 26 = - 2
also, we know that initial term = a = 26.
We know the formula for aₙ is given by:
aₙ = a + ( n - 1 ) d
Substituting the values, we get that:
aₙ = 26 + ( n - 1 ) ( - 2 )
aₙ = 26 - 2 n + 2
aₙ = 28 - 2 n
Therefore, we get that the nth term of the arithmetic sequence is given by aₙ = 28 - 2 n.

Write a function g whose graph represents the indicated transformation of the graph of f.
f(x)=4x+1; translation 2 units left.
HELP PLEASE
Answer:
The translation of 2 units left in function f (x) = 4x + 1 is 4x + 3.
Here,
Function is given as, f(x)=4x+1
And, translation 2 units left.
We have to find the function after translation.
Now,
Function is given as, f(x)=4x+1
After translation 2 units left the function is;
f (x) = 4x + 1 + 2
f (x ) = 4x + 3
Hence, the function after translation 2 units is f (x) = 4x + 3

Suppose when you study 4 hours for an exan, your mark is 80 percent. and if you study for an extra hour, your mark is 85 percernt. the marginal benefir from studying one more hour is:_________
The marginal benefit from studying one extra hour is 5 percent.
What is marginal benefit?The maximum sum of money a consumer will spend on an additional commodity or service is known as the marginal benefit. As spending rises, customer contentment tends to decline.Now,
Given:
Marks scored on studying 4 hours = 80 percentMarks scored on studying 1 hour extra = 85 percentTo find: Marginal benefit on studying one hour extra.
Finding:
Now, marks scored on studying 4 hours is 80 percent and 5 hours is 85 percent.
Thus, the extra percentage that is scored is because of the 1 hour of extra studying.
The extra percentage = marginal benefit of studying extra = 85 - 80 = 5 percent.
Hence, the marginal benefit from studying one extra hour is 5 percent.

set up a proportion
[tex]\frac{3}{4.41} = \frac{1}{x}[/tex]
cross multiply; 3x = 4.41 * 1
3x = 4.41
divide both sides by 3
x = 1.47

Write an equation representing the fact that the product of two consecutive odd integers is 255. use x to represent the smaller integer.
The first odd number = 15
The second is then = 17
The Consecutive numbers are:Consecutive numbers are those that appear consecutively after one another in the range of smallest to largest. An illustration would be the sequence of numbers 1, 2, 3, 4, 5, and so on.
Where can I find consecutive numbers?Let x be the first of the following numbers to represent it algebraically. Following that, the numbers x + 1, x + 2, and x + 3 would be arranged in order. You must make sure that your first selection is an even number if the question requires consecutive even numbers.
According to the given information:We can employ the expression "2n," where n is any integer, to ensure that the result is even. By using the expression "2n + 1," we can ensure an odd number.
"2n + 3" will be the following odd number:
(2n + 1)(2n + 3) is the component of the odd integers, and it equals 255:
(2n + 1)(2n + 3) = 255
4n2 + 8n + 3 = 255
4n2 + 8n - 252 = 0
n2 + 2n - 63 = 0
(n + 9)(n -7) = 0
n = -9 and n = 7
We can disregard n = -9 because we are informed that the figures must be positive.

what's the answer? It's difficult to understand and my teacher doesn't really teach.
Step-by-step explanation:
So for questions 1 through 4, you're basically finding the number in the middle of the two letters. In question 1, D is above 7 on the number line and E is above 11. The mid-point would be 9.
For 5 and 6, we'll be using this formula: [tex](\frac{x_{1} + x_{2}}{2},\frac{y_{1} + y_{2}}{2})[/tex]
And now we just plug in the numbers from question 5 but it works the same way on 6 as well.
[tex](\frac{3 + 5}{2},\frac{1 + 3}{2})[/tex] => (8/2, 4/2)
Coordinate of the midpoint would be (4, 2).
Lastly, we follow this system in order to get the final answers:
(Answer below shown for question 7)
(x + 2)/2 = 5
x + 2 = 10
x = 8
(y + 0)/2 = 2

a sporting event coordinator has 200 mini foam fingers she gives 2 foam fingers to each student in attendance. there are 26 left. how many students are in attendance?
thank u <3
The total number of students which are there in the sporting events are 87.
The total number of mini foam fingers which the sporting event coordinator has is 200. Since he gives 2 foam fingers to each student present in the event therefore each student has 1 pair of mini foam fingers.
So, in total there are 200/2 = 100 pairs of mini foam fingers.
The total number of mini foam fingers left after distribution is equal to 26.
So total pairs of mini foam fingers left = 26/2 = 13
Therefore, the number of students which are present in attendance is given by:
Total pairs of foam fingers - total pairs of foam fingers left
=> 100-13 = 87
Therefore, total number of students in attendance are 87.
