The series converges. It is an alternating series with terms 6/(2n+5), where n starts from 0.
1. Identify the series as alternating: The series alternates signs (positive, negative, positive, etc.).
2. Determine the general term: The general term is 6/(2n+5).
3. Apply the Alternating Series Test: Check if the sequence of absolute values is decreasing and if the limit approaches zero.
a. Decreasing: For all n, 6/(2n+5) > 6/(2(n+1)+5).
b. Limit: As n approaches infinity, the limit of 6/(2n+5) is zero.

a furniture store is having a sale where everything is 40% off. write a function that represents the amount of amount of discount d on an item with a regular price of p
d = 0.4 p, where the sales price of the bookshelf is $51, is the function that depicts the percentage off of a regular price.
What is the amount of discount ?When an item's price is lowered, it is said to be on sale. Multiplying the cost of an item by the % discount will give you the discount's value.
Discount = Original Price × Percentage Discount
$85 × 40%
$85 × 0.4 = $34.
Original cost less any discounts equals sales price.
$85 - $34 = $51.
The discount is the amount that separates an item's selling price from its marked (or list) price. Discount is therefore calculated as follows: Discount=List price – Selling price. Take advantage of deals like the buy one, get one free promotion or 15% off shirts, for instance. On an item with a price per hundred displayed, you have a percentage discount. An item that was previously priced at Rs. 1,000 is now being offered for Rs. 900 thanks to a 10% percentage discount.

Which ordered pair is in the solution set of the following system of inequalities
y≤ 3x+1
x-y>1
Therefore , the solution of the given problem of inequality comes out to be (x,y) = (1,4).
An explanation of inequalityAn inequality in mathematics is a relationship between two concepts or variables that isn't comparable. Therefore, inequality follows imbalance. When two integers are not equal, there is an inequality in mathematics. Egality and inequality are different. When two values aren't genuinely equal, the not equal basic is usually used to indicate this (). The values, whether tiny or huge, are contrasted using a variety of inequalities. By alternating the two characteristics until the constants integers become the only thing left, it is possible to solve many straightforward inequalities. However, a few things promote inequality: Negative values are halved or added to either side.
Here,
Given :
y≤ 3x+1
x-y>1
To find the value of x and y :
y≤ 3x+1
put the value of y
=> x - 3x -1 > 1
=> -2x -1>1
=>-2x > 2
=> -x>1
=>x >-1
x =1
Thus,
y≤ 3(1)+1
=> y ≤ 4
Therefore , the solution of the given problem of inequality comes out to be (x,y) = (1,4).

If P(terriers) = 15%, the interpretation of the likelihood of randomly selecting a terrier from the shelter is; Unlikely
How to find the probability of selection?Probability of selection is one that defines the probability that a population unit is included in a sample generated by probability sampling.
For any population, the probability of any element within that population to be selected into a sample is calculated as the sample size divided by the population size.
In this case, we are told that the dog shelter has Labradors, Terriers, and Golden Retrievers available for adoption. There are three types of dogs.
We are given;
P(terriers) = 15%
This means the probability of randomly selection the other 2 dogs is way higher than that to select terriers.
Thus, we conclude that the probability of selecting terriers is unlikely due to its' low probability.

if f(x)=x^3+x^2 and g(x)=x^4+x^2+x, what is the value of f(x)-g(x) when x=1
Can a triangle be constructed with sides 2.5 cm 3.0 cm and 6.5 cm give reason?
We cannot construct a triangle with side lengths 2.5 cm, 3.0 cm and 6.5 cm as they don't follow the Triangle Inequality Theorem.
It is not possible to construct a triangle using the given side lengths of 2.5 cm, 3.0 cm, and 6.5 cm. This is because of the Triangle Inequality Theorem, which states that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side.
In this case, if we take 2.5 cm and 3.0 cm as two sides, the sum of their lengths is 5.5 cm. But the length of the third side (6.5 cm) is greater than 5.5 cm, so these three side lengths cannot form a triangle.
It is important to note that this theorem applies to any triangle, whether it is acute, right or obtuse-angled triangle. It is also important to note that this theorem is necessary for the formation of a triangle, and without it, it would not be possible to form a triangle.

In mathematics, a graph is a visual representation or diagram that shows facts or values in an ordered way. The relationships between two or more items are frequently represented by the points on a graph.
Let the time be represented by the variable = x.
Let the number of dubbles be represented by the variable = y.
At x = 11, the number of dubbles y = 88.
Every hour, the farmer bought 6 more of them.
So, at x = 12 the number of dubbles y = 88 + 6
So, the table will be of the formula (x,y+6).
