Using the formula for squaring binomial evaluate the following- 54square 82 square
Answer:
2916 and 6724 respectively
Step-by-step explanation:
the steps on how to evaluate 54^2 and 82^2 using the formula for squaring a binomial are:
1. Write the binomial as a sum of two terms.
\(54^2 = (50 + 4)^2\)
\(82^2 = (80 + 2)^2\)
2. Square each term in the sum.
\(54^2 = (50)^2 + 2(50)(4) + (4)^2\\82^2 = (80)^2 + 2(80)(2) + (2)^2\)
3. Add the products of the terms.
\(54^2 = 2500 + 400 + 16 = 2916\\82^2 = 6400 + 320 + 4 = 6724\)
Therefore, the values \(54^2 \:and \:82^2\)are 2916 and 6724, respectively.
Answer:
54² = 2916
82² = 6724
Step-by-step explanation:
A binomial refers to a polynomial expression consisting of two terms connected by an operator such as addition or subtraction. It is often represented in the form (a + b), where "a" and "b" are variables or constants.
The formula for squaring a binomial is:
\(\boxed{(a + b)^2 = a^2 + 2ab + b^2}\)
To evaluate 54² we can rewrite 54 as (50 + 4).
Therefore, a = 50 and b = 4.
Applying the formula:
\(\begin{aligned}(50+4)^2&=50^2+2(50)(4)+4^2\\&=2500+100(4)+16\\&=2500+400+16\\&=2900+16\\&=2916\end{aligned}\)
Therefore, 54² is equal to 2916.
To evaluate 82² we can rewrite 82 as (80 + 2).
Therefore, a = 80 and b = 2.
Applying the formula:
\(\begin{aligned}(80+2)^2&=80^2+2(80)(2)+2^2\\&=6400+160(2)+4\\&=6400+320+4\\&=6720+4\\&=6724\end{aligned}\)
Therefore, 82² is equal to 6724.

The soap used by the machine last year is 5399.76 gallons.
What are percentages?The denominator of a percentage (also known as a ratio or fraction) is always 100. Sam, for instance, would have received 30 out of a possible 100 points if he had received 30% on his arithmetic test. In ratio form, it is expressed as 30:100 and in fraction form as 30/100. In this case, the percentage symbol "%" is read as "percent" or "percentage." This percent symbol can always be changed to a fraction or decimal equivalent by using "divided by 100."
Let the soap used last year = x.
Then, according to the given condition:
4,508.8 = x (1 - 16.5%)
4,508.8 = x (83.5/100)
x = 4,508.8(100) / 83.5

what role do your needs and wants play when creating a budget?
Your needs are essential expenses such as rent, utilities, groceries, and transportation.
These should be prioritized in your budget as they are necessary for your survival. On the other hand, your wants are non-essential expenses such as eating out, entertainment, and shopping. While it is important to treat yourself, it is also important to allocate a reasonable amount of money towards your wants. Needs and wants play a crucial role in creating a budget. A budget helps allocate financial resources according to one's priorities. Needs are essential items required for daily living, such as housing, food, and utilities. Wants are desires or non-essential items, like vacations or entertainment. While creating a budget, it's important to prioritize needs over wants to ensure financial stability. Understanding the difference between the two and allocating funds accordingly helps in maintaining a balanced lifestyle, promoting healthy spending habits, and achieving long-term financial goals. A well-structured budget ensures that you can fulfill both your needs and some wants within the allotted resources.

Needs and wants play a vital role in creating a budget by helping you prioritize your spending, make trade-offs, and allocate your financial resources effectively. By considering both your essential expenses and desired extras, you can create a balanced budget that reflects your financial goals and values.
When creating a budget, your needs and wants play a crucial role in determining how you allocate your financial resources. Here's how they factor in:
Identifying Needs: Your needs are the essential expenses required for your basic well-being and survival. These typically include housing, utilities, food, transportation, healthcare, insurance, debt repayments, and other necessary expenses. Understanding your needs helps you prioritize allocating funds to cover these essential costs first. Ensuring your needs are met is the foundation of any budget.
Prioritizing Wants: Wants, on the other hand, are things you desire or would like to have but are not essential for your survival or basic well-being. This category includes discretionary expenses such as entertainment, dining out, travel, hobbies, luxury items, and other non-essential purchases. While wants are not as critical as needs, they contribute to your overall quality of life. Allocating a portion of your budget for wants allows you to enjoy these extras within your financial means.
Trade-offs and Decision Making: Budgeting requires making decisions about how to allocate limited resources. By considering your needs and wants, you can evaluate trade-offs between various expenses. If your needs are not being fully met within your current budget, you may need to reduce or eliminate some wants temporarily to ensure your essential expenses are covered. On the other hand, if your needs are comfortably met, you have more flexibility to allocate funds toward wants or savings.
Flexibility and Adjustments: Needs and wants can evolve over time. When creating a budget, it's important to regularly reassess and adjust it to align with your changing circumstances and priorities. For instance, if your income increases, you might have more room to allocate additional funds toward wants or savings. Similarly, if your needs change, such as due to a job loss or a new family member, you may need to make adjustments to ensure your budget remains sustainable.
In summary, needs and wants play a vital role in creating a budget by helping you prioritize your spending, make trade-offs, and allocate your financial resources effectively. By considering both your essential expenses and desired extras, you can create a balanced budget that reflects your financial goals and values.

The derivative does not exist.
The function f(x) = x represents a straight line with a slope of 1. Since the slope of a straight line is constant, the derivative of f(x) = x will always be the same regardless of the value of x.
To find the derivative of f(x), we can use the power rule, which states that the derivative of x^n is equal to n*x^(n-1), where n is a constant.
In this case, since f(x) = x, we can apply the power rule with n = 1. Taking the derivative of x^1 gives us 1*x^(1-1) = 1*x^0 = 1.
So, the derivative of f(x) = x is f'(x) = 1. This means that the slope of the line represented by f(x) = x is always 1, indicating that the function has a constant rate of change.
Therefore, for any value of x, including x = 4, x = 17, and x = -6, the derivative f'(x) will be 1. In other words, the rate of change of the function f(x) = x is always 1, regardless of the specific value of x.
Hence, we can conclude that f'(4) = 1, f'(17) = 1, and f'(-6) = 1.

A cyclist traveled kilometers per hour faster than an in-line skater. In the time it took the cyclist to travel kilometers, the skater had gone kilometers. Find the speed of the skater.
The speed of skaters was 10 km per hr.
How to solve?
Mathematically, the speed of an object is directly proportional to the distance traveled and inversely proportional to the time taken. In simple words, the more the speed, the distance traveled is more in a short period and vice-versa.
Let the speed of the skater be x
We know, speed = \(\frac{Distance}{Time}\)
According to the question:
\(\frac{20}{x} = \frac{40}{x + 10}\)
Cross multiplying both sides,
20(x+10) = 40x
20x + 200 = 40x
20x = 200
x = 10
Thus, the speed of skaters was 10 km per hr.

Line a and t are parallel. What is the value of x?
7x - 48
5x
pls help me
Answer:
x = 24
Step-by-step explanation:
We know that lines s and t are parallel. Then by definition, the two labelled angles, which are same-side angles, are congruent and equal in measure.
Then, we set the expressions equal to each other:
7x - 48 = 5x
Subtract 5x from both sides:
7x - 5x - 48 = 0
2x - 48 = 0
Add 48 to both sides:
2x = 48
Divide by 2:
x = 48/2 = 24
Thus, x = 24.
