Which expressions are polynomials?

Answer:  The required slope is 2.

Step-by-step explanation:  We are given to find the slope between the points where x = 3 and x = 7 from the following table :

x      3       4      7

y      1        6      9

We know that

the slope of a line between the points (a, b) and (c, d) is given by

[tex]m=\dfrac{d-b}{c-a}.[/tex]

At x = 3, y = 1  and  at x = 7, y = 9.

Therefore, the slope between the points (3, 1) and (7, 9) is given by

[tex]m=\dfrac{9-1}{7-3}=\dfrac{8}{4}=2.[/tex]

Thus, the required slope is 2.

Solution:

we have been asked to find

The rule that describes the composition of transformations that maps figure ABCDE to figure A"B"C'D"E" is the transformation composition rule. This involves applying a translation followed by a reflection in a specific order.

The rule that describes the composition of transformations that maps figure ABCDE to figure A"B"C'D"E" is the transformation composition rule.

Transformation composition involves applying multiple transformations in a specific order. In this case, we need to determine the sequence of transformations that would result in the mapped figure.

By applying these transformations in the given order, we can map figure ABCDE to figure A"B"C'D"E".

The rule that describes the composition of transformations that maps figure ABCDE to figure A"B"C'D"E" could involve a sequence of translations, reflections, rotations, or dilations, applied in a specific order. The specific transformations and their order would depend on the given figures and the desired outcome.

The rule that describes the composition of transformations that maps figure ABCDE to figure A"B"C'D"E" is called a sequence of transformations.

A sequence of transformations involves applying multiple transformations in a specific order to transform one figure into another. In this case, the figure ABCDE is transformed into A"B"C'D"E".

Let's break down the possible transformations that could be involved in this sequence:

1. Translation: A translation moves a figure without changing its size or shape. It involves sliding the figure in a specific direction. For example, if figure ABCDE is translated 3 units to the right and 2 units up, it would result in figure A"B"C'D"E".

2. Reflection: A reflection involves flipping a figure over a line called the line of reflection. The line of reflection acts as a mirror, with each point on the figure reflecting across the line. If figure ABCDE is reflected over a line, it would result in figure A"B"C'D"E".

3. Rotation: A rotation involves turning a figure around a fixed point called the center of rotation. The figure is rotated by a specific angle in a clockwise or counterclockwise direction. If figure ABCDE is rotated 90 degrees counterclockwise around a given point, it would result in figure A"B"C'D"E".

4. Dilation: A dilation involves changing the size of a figure while maintaining its shape. The figure is either enlarged or reduced by a scale factor. If figure ABCDE is dilated with a scale factor of 2 centered at a specific point, it would result in figure A"B"C'D"E".

Fraction is a way to describe a part of a whole. The fraction is represented by the shaded part of the model is [tex]\dfrac{2}{1}[/tex].

A fraction is a way to describe a part of a whole. such as the fraction 1/4 can be described as 0.25

If we look at each of the shapes, we can observe that the whole of the shape is shaded therefore, the shaded part of the shape is equal to the shape which is represented by 1.

Now, in the image, there are two shapes given each of which is completely shaded, and the whole shape is represented by 1. therefore, these two shapes will be represented by 2.

The shaded shape can be written as,

[tex]2 = \dfrac{2}{1}[/tex]

Hence, the fraction is represented by the shaded part of the model is [tex]\dfrac{2}{1}[/tex].

A trapezoid is a quadrilateral having one set of opposing sides that are parallel to each other.  The perimeter of the trapezoid is equal to 32 inches.

A trapezoid is a quadrilateral having one set of opposing sides that are parallel to each other. It can have right angles (a right trapezoid) and congruent sides (isosceles), but neither is necessary.

As is mentioned that the area of the trapezoid is 69.6 in², while its altitude is 8.7 inches. Therefore, the sum of the bases of the trapezoid can be written as,

[tex]\rm \text{Area of trapezoid} = \dfrac{1}{2} \times (Base_1 + Base_2) \times Altitude[/tex]

[tex]69.6 = \dfrac{1}{2} \times (b_1 + b_2) \times 8.7\\\\(b_1 +b_2) = 16\rm\ inches[/tex]

Now, it is mentioned that the sum of the legs of the trapezoid is equal to the sum of its bases. Therefore, the perimeter of the trapezoid is,

[tex]\text{Perimeter of Trapezoid} = (\text{Sum of its bases}) +(\text{Sum of its legs})\\\\\text{Perimeter of Trapezoid} = 16+16 = 32\rm\ inches[/tex]

Hence, the perimeter of the trapezoid is equal to 32 inches.

a) π · (12 · tan 70°)2. To find the area of the ground covered by the conical tent, use the formula for the surface area of a cone, A = πr(r+√(r^2+h^2)).

To find the area of the ground covered by the conical tent, we can use the formula for the surface area of a cone. The formula is A = πr(r+√(r^2+h^2)), where r is the radius and h is the height of the cone.

In this case, the height of the cone is 12 feet and the angle it makes with the ground is 70°. To find the radius, we can use trigonometry. The radius is given by r = h tanθ, where θ is the angle with the ground. Plugging in the values, we get r = 12 tan(70°).

Now, substituting the value of r into the formula for the surface area of the cone, we get A = π(12 tan(70°))(12 tan(70°)+√((12 tan(70°))^2 + 12^2)). This simplifies to option a) π · (12 · tan 70°)2.

Final answer:

To determine how much the 34-pound dog should eat, set up a proportion based on the 15-pound dog's food intake. After setting up the proportion 15 pounds / 2 1/8 cups = 34 pounds / x cups and solving it, we find that the 34-pound dog should eat approximately 4.82 cups per day.

Explanation:

The question deals with proportional relationships and mathematics, specifically in finding out how much dog food to feed a dog based on its weight. To solve this problem, we need to establish a ratio or proportion from the information provided and then use it to find out how much food the 34-pound dog should eat.

A 15-pound dog eats 2 1/8 cups of dog food per day. We convert 2 1/8 cups to an improper fraction which is 17/8 cups. Now, we set up the proportion:

15 pounds / (17/8 cups) = 34 pounds / x cups

By cross-multiplying we have:

15 * x = 34 * (17/8)

x = (34 * 17) / (8 * 15)

x = (578) / (120)

After simplifying the fraction, we obtain x = 4.8166 which we can round to 4.82 cups per day for a 34-pound dog.
