Yes, there are several ways to understand the concept of a limit in calculus without going into the details of a formal proof. One way to understand the concept of a limit is to think of it as a way to measure how close a function gets to a particular value as the input to the function gets closer and closer to a certain number. For example, if we have a function f(x) and we want to find the limit of the function as x approaches 2, we can think of this as asking "how close does f(x) get to a certain number as x gets closer and closer to 2?"

Another way to understand the concept of a limit is to think of it as a way to describe the behavior of a function as the input gets very large or very small. For example, if we have a function f(x) and we want to find the limit of the function as x approaches infinity, we can think of this as asking "how does f(x) behave as x gets very large?"

Overall, the concept of a limit is a fundamental concept in calculus that allows us to describe and analyze the behavior of functions as the input to the function changes. While a formal proof of the limit can be quite complex, there are several intuitive ways to understand the concept without going into the details of the proof.

The loan have a higher monthly payment Because the lease is riskier to the financing company.

To Determine the costs of buying versus leasing a motor vehicle, we need to consider the total costs associated with each option. For buying, the total cost is the sum of the down payment, loan payments, and the estimated value at the end of the loan, minus the resale value of the car.

On the other hand, for leasing, the total cost can be calculated as the sum of the security deposit, lease payments, and end-of-lease charges. We also need to consider the opportunity cost of investing the down payment and the security deposit.

We know that Melisha can pay for her vehicle with a 4-year loan or with a lease with the same down payment and same interest rate.

Therefore, the loan have a higher monthly payment Because the lease is riskier to the financing company.

Step-by-step explanation:

The question is how to divide this this is how to solve it

Answer:

Therefore, the solution to the equation -x + 3y = 11 is x = -34/11 and y = 29/11.

Step-by-step explanation:

The given equation is:

-x + 3y = 11

To solve this equation by elimination, we need to add or subtract one or both equations to eliminate one of the variables. In this case, we can eliminate the variable x by adding the equation with another equation that has x with the same coefficient, but opposite sign.

Let's suppose we have another equation with x, for example:

2x + 5y = 7

We can eliminate x by multiplying the first equation by 2 and the second equation by 1, so that the coefficients of x are opposite:

-2x + 6y = 22 (multiply the first equation by -2)

2x + 5y = 7 (the second equation)

Now we can add the two equations to eliminate x:

-2x + 2x + 6y + 5y = 22 + 7

Simplifying the equation, we get:

11y = 29

Dividing both sides by 11, we get:

y = 29/11

Now that we know the value of y, we can substitute it back into one of the original equations to find the value of x. Let's use the first equation:

-x + 3y = 11

Substituting y = 29/11, we get:

-x + 3(29/11) = 11

Simplifying the equation, we get:

-x + 87/11 = 11

Subtracting 87/11 from both sides, we get:

-x = 11 - 87/11

Multiplying both sides by -1, we get:

x = 87/11 - 11

Simplifying the equation, we get:

x = (87 - 121)/11

x = -34/11

The ratio of the sides of the small box and the medium box is 1:3

The ratio of the area of the bases of the small box and the medium box is 1:9.

The ratio of the volumes of the small box and the medium box is 1:27.

The volume of a medium box is 5832 cubic inches.

What is a cube?

The solid shape of a cube has six square faces. Because every square face has the same side length, each face is the same size. A cube has 8 vertices and 12 edges. Each vertex is the intersection of three cube edges.

Given that a cube-shaped small packaging box has a volume of 216 cubic inches.

Assume the length of sides is a.

The volume of a cube is side³.

The volume of the small box is a³.

Thus,

a³ = 216

a³ = 6³

a = 6

The length of the small box is 6.

The area of the base of small box is 6×6  = 36 square inches.

The dimensions of a medium box are tripled in length, width, and height.

Thus the length of the medium box is 3×6 = 18 inches.

The area of the base of the medium box is 18×18 = 324 square inches.

The volume of cube medium box is 18×18×18 = 5832 cubic inches.

The ratio of the sides of small box and medium box is

6:18 = 1:3

The ratio of the area of bases of small box and the medium box is

36:324 = 1:9

The ratio of the volumes of small box and the medium box is

216:5834 = 1:27

A frequency distributiοn graph is a different apprοach tο displaying data that has been represented graphically.

The range οf the data is the difference between the maximum and minimum values:

Maximum value: 5.4

Minimum value: 3.4

Range: 5.4 - 3.4 = 2.0

Next, we divide the range by the desired number οf classes tο find the class width:

Class width = 2.0 / 6 = 0.3333 (rοunded tο 0.4)

Based οn the given data, we can expect the histοgram tο be apprοximately bell-shaped, with a peak arοund the middle classes (4.0-4.8) and fewer pencils in the extreme classes (3.4-3.8 and 5.4-5.8).

Since three identical small rectangles are joined to form a large rectangle, the large rectangle will have three times the length and the width of a small rectangle.

Let's assume the width of one small rectangle is x cm. Therefore, the length of one small rectangle will be 21 cm - 2x cm (since two widths are subtracted from the total perimeter).

The perimeter of one small rectangle is given by:

Perimeter = 2 * (length + width)

Perimeter = 2 * ((21 - 2x) + x)

Perimeter = 2 * (21 - x)

Perimeter = 42 - 2x

Since the large rectangle is formed by joining three identical small rectangles, the perimeter of the large rectangle will be three times the perimeter of one small rectangle.

Perimeter of the larger rectangle = 3 * (42 - 2x)

Perimeter of the larger rectangle = 126 - 6x

Therefore, the perimeter of the larger rectangle is 126 - 6x cm.

The revenue equation is given by:

R = –360p^2 + 28,800p

To find the maximum revenue that can be expected, we need to find the vertex of the parabola represented by this equation. The vertex of a parabola is given by the formula:

Vertex = (-b/2a, f(-b/2a))

where a, b, and c are the coefficients of the quadratic equation ax^2 + bx + c = 0.

In this case, a = -360 and b = 28,800.

The x-coordinate of the vertex is given by:

x = -b/2a = -28,800/(2*(-360)) = 40

Substituting x = 40 into the revenue equation gives:

R = –360(40)^2 + 28,800(40) = 576,000

Therefore, the maximum revenue that can be expected is $576,000.

The algorithm/abstract strategy to justify the fraction 3/5 involves interpreting it as a division, performing the division, and obtaining the decimal representation as the results.

To justify the fraction 3/5, we can use the concept of division and understand it as a ratio or proportion.

Algorithm/Abstract Strategy:

Start with the numerator, which is 3.

Identify the denominator, which is 5.

Interpret the fraction as a ratio or comparison between the numerator and denominator.

Understand that 3/5 represents a division where the numerator (3) is divided by the denominator (5).

Perform the division: 3 ÷ 5.

Simplify the division to its simplest form, if necessary.

The result of the division, in this case, is the decimal representation of the fraction.

If required, convert the decimal representation to a percentage or any other desired form.

For example, if we perform the division 3 ÷ 5, the result is 0.6.

So, 3/5 can be justified as the ratio or proportion where the numerator (3) is divided by the denominator (5) resulting in 0.6.

Jimmy  has five dollars more than three times Bethany has. Jimmy has $31.25.

A mathematical statement with two equal algebraic expressions is called an algebraic equation. Equations in algebra with only one variable are referred to as univariate equations, while equations with several variables are referred to as multivariate equations.

Let's say Jimmy has \(x\) dollars.

Three times the amount of money Bethany has is \(3x\).

Jimmy has 5 dollars more than three times what Bethany has,

so, \(x = 3x + 5\)

The combined amount of money Jimmy and Bethany have is $130,

so, \(x + 3x +5= 130\)

Combining like terms, \(4x = 125\).

I'll give you a basic idea on how to do them

Pythagoras theorem

If you know two other sides of the right triangle, it's the easiest option; all you need to do is apply the Pythagorean theorem:

a² + b² = c²

If a is the missing side, then transform the equation to the form where a is on one side and take a square root:

a = √(c² - b²)

If b is unknown, then:

b = √(c² - a²)

If c is unknown, then:

c = √(a² + b²)

5.

a=5, b=7 and c=?

c=√(5^2 + 7^2)

c= √(25 + 49)

c= √74
