Calculus a broad subject that covers many topics such as derivatives, integrals, limits, and functions.

Calculus is a branch of mathematics that focuses on the study of change and motion. It provides a framework for understanding and analyzing quantities that vary continuously. The two main branches of calculus are differential calculus and integral calculus.

Differential calculus deals with the concept of derivatives. A derivative measures how a function changes as its input (usually denoted as x) changes. Geometrically, the derivative represents the slope of a function at a particular point. It can also be interpreted as the instantaneous rate of change of a function at a given point. Derivatives have various applications, such as determining the maximum or minimum values of functions, analyzing the behavior of functions, and solving optimization problems.

Integral calculus, on the other hand, focuses on the concept of integrals. An integral is a mathematical operation that measures the accumulation of quantities or the area under a curve. It essentially reverses the process of differentiation. Integrals can be used to compute the total change or accumulation of a quantity over a given interval, find the area of irregular shapes, and solve problems involving rates of change.

Calculus plays a fundamental role in many scientific and engineering disciplines. It is used extensively in physics, engineering, economics, computer science, and many other fields to model and solve real-world problems involving continuous change. The study of calculus also forms the basis for higher-level mathematics such as differential equations, vector calculus, and multivariable calculus.

The equation of the line that passes through the points (-2, 4) and (3, 9) is y = x + 6.To find the equation of a line in slope-intercept form (y = mx + b), we need to determine the slope (m) and the y-intercept (b) using the given points (-2, 4) and (3, 9).

First, let's find the slope (m) using the formula:

m = (y2 - y1) / (x2 - x1)

Substituting the values from the points:

m = (9 - 4) / (3 - (-2)) = 5 / 5 = 1

Now that we have the slope, we can proceed to find the y-intercept (b). We can choose either of the given points to substitute into the equation.

Using the point (-2, 4):

4 = 1(-2) + b

4 = -2 + b

b = 6

Therefore, the y-intercept (b) is 6.Now we have the slope (m = 1) and the y-intercept (b = 6), so the equation of the line in slope-intercept form is:

One serving of tomato juice has mg of more vitamin C per serving is 90mg.

We are given that;

Tomato juice percentage of vit c

Now,

The Daily Value (DV) for vitamin C is 90 mg for adults and children aged 4 and older. This value is used to calculate the percent DV that you see on nutrition labels. So, if one serving (1 cup or 240 ml) of 100% canned tomato juice contains 74% of the DV for vitamin C, this means that one serving contains approximately 66.6 mg of vitamin C

Solving this calculation;

0.74 x 90 mg = 66.6 mg

The DV for vitamin C=90 mg.

Therefore, by percentage the answer will be 90mg.

Answer:

The relationship between the number of faces, vertices, and edges of a three-dimensional object is described by Euler's formula, which states that for any polyhedron (a solid object bounded by flat faces), the number of faces (F), vertices (V), and edges (E) satisfy the equation F + V - E = 2. This formula is true for any convex polyhedron, such as a cube or a regular tetrahedron.

The formula is based on the fact that every face of a polyhedron is bounded by a closed loop of edges, and each vertex is where three or more edges meet. The total number of edges is the sum of the number of edges around each face, which is equal to twice the number of faces since each edge is shared by two faces, and the number of edges meeting at each vertex, which is equal to the degree of the vertex (the number of edges meeting at the vertex).

Therefore, by knowing the number of faces, vertices, and edges of a three-dimensional object, we can determine if it is a convex polyhedron and use Euler's formula to check if the numbers are consistent with a solid shape.

Step-by-step explanation:

The customer would pay a net price of $760 per item after all discounts have been applied. It's important to note that the Actual discount percentage and net price per item may vary depending on the terms of the sale and the specific furniture center's policies.

Furniture centers often offer trade discounts to their customers to encourage orders. A trade discount is a reduction in the listed price of a product or service that is offered to trade customers, such as retailers, wholesalers, or other businesses. The discount is usually a percentage of the list price, and the actual amount of the discount depends on the quantity of the product ordered and the terms of the sale.

In addition to trade discounts, furniture centers may offer additional discounts to their customers who meet certain criteria. For example, they may offer a percentage discount for orders over a certain amount or for customers who pay in full at the time of purchase. These additional discounts are intended to encourage customers to place larger orders and to reward them for their loyalty to the furniture center.

To calculate the net price per item, you need to know the list price of the item, the trade discount percentage, and any additional discounts that may apply. For example, let's say that the list price of a piece of furniture is $1,000, and the trade discount offered by the furniture center is 20%. If the customer's invoice total is high enough to qualify for an additional discount of 5%, the net price per item would be calculated as follows:

List price: $1,000

Trade discount: 20% x $1,000 = $200

Price after trade discount: $1,000 - $200 = $800

Additional discount: 5% x $800 = $40

Net price per item: $800 - $40 = $760

So, the customer would pay a net price of $760 per item after all discounts have been applied. It's important to note that the actual discount percentage and net price per item may vary depending on the terms of the sale and the specific furniture center's policies.

Answer: $0.0195

Step-by-step explanation: To find the price per ounce of apple juice, we need to divide the total cost by the number of ounces.

Price per ounce = Total cost / Number of ounces

Here, the total cost is $2.50 and the number of ounces is 128.

Price per ounce = $2.50 / 128 ounces

Price per ounce = $0.0195

Therefore, the price per ounce of apple juice is $0.0195, which is approximately 2 cents per ounce.

Answer: $0.0195 per ounce

Step-by-step explanation:

We will create a proportion to help us solve this question.

➜ To do this, we will set two fractions equal to each other with the dollar amount in the numerator and the ounce amount in the denominator.

[tex]\displaystyle \frac{\$2.50}{128\;ounces} =\frac{\$x}{1\;ounce}[/tex]
