One example of such a series is the harmonic series with alternating signs:
∑n1(−1)nn= −1/1 + 1/2 − 1/3 + 1/4 − 1/5 + ...
This series alternates between positive and negative terms, with the magnitude of each term decreasing as n increases. Therefore, we can choose c
n
to be the absolute value of each term, which is always less than 0.0000001 for sufficiently large n.
Additionally, we know that the limit of the sequence of terms is zero, since the terms approach zero as n goes to infinity. However, the series still diverges, as shown by the alternating series test. Therefore, this series satisfies the conditions given in the problem.

Would the following compound inequality be classified as an “and” inequality or an “or” inequality? Inequality: 6 > x + 1 > 3 dont guess
The inequality 6 > x + 1 > 3 is 'And' type Inequality.
What is Inequality?Mathematical expressions with inequalities are those in which the two sides are not equal. Contrary to equations, we compare two values in inequality. Less than (or less than or equal to), greater than (or greater than or equal to), or not equal to signs are used in place of the equal sign.
Given:
An 'Or' inequality is also referred to as a disjunction.
In other words, there is no connection on the number line between the range of values that meet either component of the inequality. Finding a truthful statement that satisfies either one of the inequality conditions or both inequality conditions is the aim whenever 'Or' compound inequalities are solved.
For example, x > 7 OR x < 3
Another name for a compound inequality with a 'And' is a conjunction. Compound inequality of this kind is stated as a long inequality, such as
3 > x > 9. Similar to 3>x and x > 9, this is.
The solutions to this and other compound inequalities fall within a range of potential values between 3 and 9. The range of values used to solve "And" inequalities must meet both requirements. These inequalities display a range of overlapping values.
So, the inequality is 'And' type of Inequality.

Answer: the total spent on the meal is $88.25875.
Step-by-step explanation:
The total spent on the meal can be calculated by adding the cost of the meal, the tax, and the tip.
First, we need to calculate the cost of the tax: 72.5 x 0.0675 = 4.88375
Then we need to calculate the cost of the tip: 72.5 x 0.15 = 10.875
Finally, we add the cost of the meal (72.5), the tax (4.88375) and the tip (10.875) to find the total cost of the meal: 72.5 + 4.88375 + 10.875 = 88.25875
Therefore, the total spent on the meal is $88.25875.
one number exceeds (is more than) another number by 6, and the sum of the two numbers is 26. find the two numbers
Answer:
10 and 16
Step-by-step explanation:
let on number be x then the other number is x + 6
sum the 2 numbers and equate to 26
x + x + 6 = 26
2x + 6 = 26 ( subtract 6 from both sides )
2x = 20 ( divide both sides by 2 )
x = 10
x + 6 = 10 + 6 = 16

What is the equation of the line that passes through the point (-6, 5) and has a slope of 1/2
The equation of a line passes through the point (-6, 5) and
has a slope of 1/2 is y = (1/2)x + 8.
What are lines and their slopes?We know lines have various types of equations, the general type is
Ax + By + c = 0, and equation of a line in slope-intercept form is y = mx + b.
Where slope = m and b = y-intercept.
the slope is the rate of change of the y-axis with respect to the x-axis and the y-intercept is the (0,b) where the line intersects the y-axis at x = 0.
Given, A line passes through the point (-6, 5) and has a slope of 1/2.

Jee's trip from New York to Boston would take approximately time 4.5 hours.
To calculate the time it would take Jee to travel from New York to Boston, we need to divide the total distance (approximately 280 miles) by the average speed (42 mph). This gives us a total time of 6.67 hours. We then need to subtract the time it took Jee to travel from Boston to New York (6 hours) to get the total time for the return trip. 6.67 hours - 6 hours = 4.5 hours. Therefore, Jee's trip from New York to Boston takes approximately time 4.5 hours. Jee's trip from New York to Boston would take approximately 4.5 hours.

How do you find the 1st and 2nd element of a pair?
An ordered pair is a set of two values, (x,y), where x and y are the coordinates. In an ordered pair, the first element is typically referred to as the x-coordinate, or the "first component" and it represents the horizontal position of the point on a coordinate plane. The second element is typically referred to as the y-coordinate, or the "second component" and it represents the vertical position of the point on a coordinate plane.
So, to find the first and second element of a pair, you can refer to the first element as the x-coordinate or the first component and the second element as the y-coordinate or the second component.
For example, in the ordered pair (4,3), the first element is 4, which represents the x-coordinate, and the second element is 3, which represents the y-coordinate.

A two-dimensional (2D) coordinate system is a system used to define the position of points in a two-dimensional plane.
What is 2D coordinates system?A 2D coordinate system can also be used to represent other kinds of data, such as temperature, elevation, or pressure. In this case, the two coordinates are usually called the x-axis and y-axis, and they are both used to measure the same physical quantity.
It is most commonly used in mathematics and engineering to plot graphical data such as graphs, charts, and diagrams. In a 2D coordinate system, each point is represented by two numbers, called coordinates, which indicate the position of the point in relation to a fixed reference point, called the origin. These coordinates usually describe the horizontal (x) and vertical (y) distances between the point and the origin. The set of all points in the 2D coordinate system is called the coordinate plane.

Answer:
a. Write an inequality that demonstrates this situation
Let x be the number of $5 t-shirts Tyrone can buy
The inequality that demonstrates this situation is:
x*5 + 22 <= 95 - 15
b. solve your inequality
x5 + 22 <= 80
x5 <= 58
x <= 11.6
x <= 11
c. Explain what your answer means to Tyrone
Tyrone has $95 to spend, he already bought pants for $22, so he has $95-22 = $73 left to spend. He wants to have at least $15 left over after buying t-shirts, so he can buy up to $73-15 = $58 worth of t-shirts. Each t-shirt costs $5, so he can buy a maximum of 11 t-shirts (58/5=11.6) with no remainder. So Tyrone can buy 11 t-shirts and he will have $73-11*5 = $18 left. This means that Tyrone can buy 11 t-shirts and still have $18 left over.

-8+2x>4
By solving the given inequality in question, i.e -8+2x>4 , the solution obtained is x>6, which means the inequality satisfies for all the values of x that are greater than 6.
What is inequality?An inequality is a statement that compares two values and asserts that one value is greater than, less than, or not equal to the other value. Inequalities are used to describe a range of values that a variable can take on. The most common symbols used to express inequalities are ">", "<", "≥" and "≤", which represent "greater than", "less than", "greater than or equal to" and "less than or equal to" respectively.
Give an example of inequality?An example for inequality can be , the inequality x > 2 , which states that x is greater than 2, which means that any value of x that is greater than 2 satisfies the inequality.
Inequality can be solved either graphically or algebraically. The solution of an inequality is the set of all values that make the inequality true.
To solve the inequality -8 + 2x > 4, you can follow these steps:
Add 8 to both sides of the inequality: -8 + 2x > 4 becomes 2x > 12Divide both sides of the inequality by 2 : 2x > 12 becomes x > 6So the solution of the inequality is x > 6.
This means that x is greater than 6. So any value of x that is greater than 6 satisfies the inequality.
