Vertex: What is it?

A vertex is a location in geometry where two or more curves, lines, or edges converge. It is also referred to as the intersection of an object's edges, faces, or facets to form a corner point of a polygon, polyhedron, or other higher-dimensional polytope. Each of the three corners of a triangle, for instance, is a vertex.

x = -b / 2a

where -10 a and 120 b. By replacing these values, we obtain:

x = -120 / 2(-10) = 6

Let the people stayed be x

Because of this, July is the month with the most guests at the inn (6 months after January).

We may change x = 6 into N(x) to get the number of visitors who stayed at the inn during that month:

We must determine the highest value of N in order to determine the month when the inn had the most guests (x).

N(x) = -10x² + 120x + 120

N(6) = -10(6)² + 120(6) + 120 guests.

N(6) = -360 + 720 + 120

N (6) = 360+120

After answering the provided question, we can conclude that Therefore, function the derivative of[tex]f(x) = x^2 at x =[/tex]1 is equal to 2.

In mathematics, a function appears to be a relationship among two the numerical sets in which each citizen of the first set (identified as the domain) corresponds to a specific member of the second set (called the range). In other words, a function collects information from one set and produces output from another. The factor x has frequently been used to represent inputs, and the variable y has been used to represent outputs. A formula or a graph can be used to represent a function. For example, the formula y = 2x + 1 represents a general solution whereby each value of x yields a unique value of y.

[tex]f'(x) = lim(h - > 0) [f(x + h) - f(x)] / h \\f(1) = 1 \\f(1+h) = (1+h)^2 \\f(1+h) - f(1) = (2h + h^2) \\lim(h - > 0) [2h + h^2] / h = lim(h - > 0) [2 + h] = 2 \\f'(1) = 2 \\f'(x) = lim(h - > 0) [f(x + h) - f(x)] / h\\[/tex]

Let the unit cost per pound of strawberries = x

Let the unit cost per pound of blueberries = y

2x + 1.8y = 15.52 ... Equation 1

2.5x + 3.6y = 21.95 ...Equation 2

Multiply Equation 1 by 2:

The domain of the inverse function f⁻¹⁽ˣ⁾ is (-2, 5), and the range is [3, 4).

The domain refers to the set of input values for which a function is defined. For example, the domain of the function f(x) = √(x) is all non-negative real numbers, because the square root function is only defined for non-negative inputs.

The range refers to the set of output values that a function can produce, given its domain of input values. In other words, it represents the set of possible values that a function can output.

In the given question,

Since f(x) is a one-to-one function, it has an inverse function f⁽⁻¹⁾⁽ˣ⁾, which can be found by switching the roles of x and y and solving for y.

To find the domain and range of the inverse function f⁽⁻¹⁾⁽ˣ⁾, we can use the fact that the domain of f(x) is equal to the range of f^⁽⁻¹⁾⁽ˣ⁾, and the range of f(x) is equal to the domain of f⁽⁻¹⁾⁽ˣ⁾.

So, we have:

Domain of f(x) = [3, 4)

Range of f(x) = (-2, 5)

Range of f⁽⁻¹⁾⁽ˣ⁾ = Domain of f(x) = [3, 4)

Domain of f⁽⁻¹⁾⁽ˣ⁾ = Range of f(x) = (-2, 5)

Therefore, the domain of the inverse function f⁽⁻¹⁾⁽ˣ⁾ is (-2, 5), and the range is [3, 4).

What is a rectangular prism?

A right rectangular prism is a box-shaped object, that is, a 3-dimensional solid which has six rectangular faces. Rectangular prisms can also be oblique - leaning to one side - but the side faces are parallelograms, not rectangles. A right rectangular prism is also called a cuboid, box, or rectangular hexahedron. Moreover, "rectangular prism" and "right rectangular prism" are often used interchangeably.

The most common math problems related to this solid are of the type right rectangular prism calc find V or find A, where the letters stand for the Volume and Area, respectively. Let's see the necessary rectangular prism formula and learn how to solve those problems quickly and easily.

How do I find the volume of a rectangular prism?

The rectangular prism volume formula is:

volume = h × w × l,

where h is prism height, w is its width, and l is its length. To calculate the volume of a cardboard box:

Find the box length. For example, it can be equal to 18 in.

Determine its width. Let's say you measured 12 in.

Find out the rectangular prism height. Assume it's 15 in.

Calculate the cuboid volume. Using the rectangular prism volume formula above, we get volume = (18 × 12 × 15) in = 3240 in³.

How do I find the area of a rectangular prism?

The surface area of the cuboid consists of 6 faces - three pairs of parallel rectangles. To find the rectangular prism surface area, add the areas of all faces:

surface_area = 2 × (h × w) + 2 × (h × l) + 2 × (l × w) = 2 × (h × w + h × l + l × w),

where h is prism height, w is its width, and l is its length.

Let's see an example of how to solve the right rectangular prism calc - find A problem. We'll come back to our example with the box and calculate its surface area:

Calculate the rectangular prism surface area. First rectangle area is 15in × 12in = 180in², second 15in × 18in = 270in² and third one 18in × 12in = 216in². Add all three rectangles' areas - it's equal to 666 in² (what a number!) - and finally multiply by 2. The surface area of our cardboard box is 1332in².

Or save yourself some time and use our rectangular prism calculator.

Finally, let's attack the right rectangular prism calc find d (that is, the diagonal) type of problem.

How do I calculate the diagonal of a rectangular prism?

To detewrmine the diagonal of a rectangular prism, apply the formula:

diagonal = √(l² + h² + w²)

where h is prism height, w is its width, and l is its length.

Answer:

If Lin's father has an 18% tip for the meal, he will need to pay an additional 0.18 x 23.89 = 4.3 dollars as a tip. This brings the total cost of the meal to 23.89 + 4.3 = 28.19 dollars.

Next, a 7% sales tax is applied to the total cost of the meal, which is 28.19 dollars. The amount of sales tax will be 0.07 x 28.19 = 1.97 dollars.

Therefore, the total amount that Lin's father will pay for the meal including the tip and sales tax is 28.19 + 1.97 = 30.16 dollars.

In statistics, the mean (or arithmetic mean) is a measure of central tendency of a set of numerical data. It is the sum of all the values in the data set divided by the total number of values.

In scenario B, the paired samples are the healthy patients and patients with cancer, and we want to test if there is a difference in the mean number of CD4 T cells between these two groups.

In scenario D, the paired samples are husbands and wives, and we want to test if there is a difference in their mean annual income.

In scenario E, the paired samples are the same patients before and after surgery, and we want to test if there is a difference in the mean number of antibodies before and after surgery.

First, we need to convert the length of the leather cord to inches because the length of the necklace is given in inches.

3 yards = 3 x 3 = 9 feet (since there are 3 feet in a yard)

9 feet = 9 x 12 = 108 inches (since there are 12 inches in a foot)

Now we can divide the length of the leather cord by the length of each necklace:

108 inches ÷ 28 inches = 3.857

Since we cannot make a fraction of a necklace, we round down to the nearest whole number:

3 necklaces

Therefore, Cindy can make 3 necklaces with the piece of leather cord she has.

       First, we will solve for the area of the triangles. Since they are congruent, we will multiply the height times the base. Usually, you would have to divide by two. However, since we have two congruent triangles, we will not be doing this.

       A = BH

       A = (2 m)(6 m)

       A = 12 m²

       Next, we will find the area of the rectangle. We will multiply the length by the width.

       A = BH

       A = (6 m)(4 m)

       A = 24 m²

       Lastly, we will add these two values together.

24 m² + 12 m² = 36 m²

The simplified polynomial in standard form that represents the result of subtracting (z-7)² from 62 is -z² + 14z + 13.

Given that, ( z - 7 )² is subtracted from 62.

To subtract ( z - 7 )² from 62, we first need to first expand this ( z - 7 )².

( z - 7 )²

Answer:

460 milliliters

Step-by-step explanation:

We know that the ratio of A to B is 5:7. This means for every 5 milliliters of A, we need 7 milliliters of B. Let's use this ratio to find how many milliliters of A we need for 1104 milliliters of the drug.

First, we need to find out how many sets of 5:7 we have in 1104 milliliters. We can do this by dividing 1104 by the total number of parts in the ratio, which is 5 + 7 = 12.

1104 / 12 = 92

This means we have 92 sets of 5:7 in 1104 milliliters of the drug. To find how many milliliters of A we need, we simply multiply the number of sets by the amount of A in each set, which is 5 milliliters.

92 x 5 = 460

Therefore, we need 460 milliliters of compound A.
