Table:

| x  | y = x^2 + 2 |

|----|-------------|

|-3  | 11          |

|-2  | 6           |

|-1  | 3           |

| 0  | 2           |

| 1  | 3           |

| 2  | 6           |

| 3  | 11          |

let's complete a table for the rule [tex]\( y = x^2 + 2 \)[/tex] by plugging in various values of [tex]\( x \)[/tex], including negative, positive, and zero, and then calculating the corresponding values of [tex]\( y \)[/tex] .

Given the rule [tex]\( y = x^2 + 2 \)[/tex], we'll substitute different values of [tex]\( x \)[/tex] into the equation and solve for [tex]\( y \)[/tex]. Here's a step-by-step process:

1. Choose values for [tex]\( x \)[/tex]. Let's pick a range of values, including negative, positive, and zero, to get a good representation of the function.

2. Substitute each chosen value of [tex]\( x \)[/tex] into the equation [tex]\( y = x^2 + 2 \)[/tex].

3. Calculate the corresponding value of [tex]\( y \)[/tex] by performing the arithmetic operations.

4. Record the pairs of [tex]\( x \)[/tex] and [tex]\( y \)[/tex] values in a table.

Here's the completed table:

| [tex]\( x \) | \( y = x^2 + 2 \)[/tex] |

|---------|-----------------|

| -3      | [tex]\( (-3)^2 + 2 = 9 + 2 = 11 \)[/tex] |

| -2      | [tex]\( (-2)^2 + 2 = 4 + 2 = 6 \)[/tex] |

| -1      | [tex]\( (-1)^2 + 2 = 1 + 2 = 3 \)[/tex] |

| 0       | [tex]\( (0)^2 + 2 = 0 + 2 = 2 \)[/tex] |

| 1       | [tex]\( (1)^2 + 2 = 1 + 2 = 3 \)[/tex] |

| 2       | [tex]\( (2)^2 + 2 = 4 + 2 = 6 \)[/tex] |

| 3       | [tex]\( (3)^2 + 2 = 9 + 2 = 11 \)[/tex] |

This table shows the relationship between [tex]\( x \)[/tex] and [tex]\( y \)[/tex] for the given rule [tex]\( y = x^2 + 2 \)[/tex], covering a range of values for [tex]\( x \)[/tex] including negative, positive, and zero.

To find the square footage of a wall painted blue, you would first calculate the total size of the wall by multiplying the wall's height and length. Then, you would multiply this number by the proportion of the wall you plan to paint blue. This will give you the number of square feet that will be coloured blue.

This question pertains to the mathematical concept of resolving problems involving areas and percentages. Marcus's wall's total area can be calculated by multiplying the wall's length and height. However, since the measurements have not been provided in the question, let's assume their values to be 'L' and 'H' feet respectively. The area of the wall would then be simply H*L square feet.

Now, if Marcus decides to cover a certain percentage of this wall with blue paint, we must determine the total square feet being painted. If the proportion of the wall to be painted is 'P', the blue-painted area is given by H*L*P (P being a decimal representation of the given percent, i.e., 20% would be represented as 0.20).

Therefore, the number of square feet that will be blue is the product of the total wall area and the proportion to be painted blue.

The correct choice is, No, because there is a lot of variability in the language arts book data.

Mean of a set of data is defined as the average of all the values. It gives the exact middle point of the data set.

From the given data, it is clear that the mean number of pages of language arts book is greater than that of social studies book.

However, the mean absolute deviation is greater for language arts book and median is lower for language arts book.

This clears the fact that the variability is high for language arts book. So the number of pages could actually be less than that in social studies book.

Hence the correct option is that we cannot say a valid inference because there is a lot of variability in the language arts book data.

When m = 7, the expression 5m - 6 evaluates to 29.

To evaluate the expression 5m - 6 for m = 7, we substitute m with 7:

5m - 6 = 5(7) - 6

Next, we perform the multiplication first:

5(7) = 35

Now we can substitute the value into the expression:

5m - 6 = 35 - 6

Finally, we perform the subtraction:

35 - 6 = 29

Therefore, when m = 7, the expression 5m - 6 evaluates to 29.

The volume of oil currently in the cylindrical tank that is 1/4 full is (90/4) cubic feet.

To determine how much oil in cubic feet is currently in the cylindrical tank when the tank is 1/4 full, we use the formula for the volume of a cylinder, V =
2h, where r is the radius and h is the height. In this case, the radius is 3 feet and the height of the oil will be 1/4 of the total height of the tank.

First, calculate the volume of the entire tank:

Vtotal =  2h = 2(10). Plugging in the values we get

Vtotal =
(3)2(10).

Since the tank is 1/4 full, the volume of oil in the tank will be 1/4 of the total volume: Voil = (1/4)Vtotal = (1/4)
(3)2(10) = (9/4)
(10) = (90/4)
.

Therefore, the volume of oil in the tank is (90/4) cubic feet.

Answer:

[tex]7\ mm^{2}[/tex]

Step-by-step explanation:

we know that

The area of the resulting two-dimensional cross-section is the area of a rectangle

The area of a rectangle is equal to

[tex]A=bh[/tex]

we have

[tex]b=3.5\ mm[/tex]

[tex]h=2\ mm[/tex]

substitute

[tex]A=3.5*2=7\ mm^{2}[/tex]

Given is the irregular hexagon.

We can divide the given figure into two triangles and one rectangle, and then find areas of each, and then add all of them to find the final answer.

We can find the dimensions by counting the blocks on graph. Given two triangles are identical in shape with base (b=7) and height (h=2).

The area of triangle [tex] =\frac{1}{2} bh = \frac{1}{2} (7)(2) = 7 [/tex] squared units.

Area of two triangles = 14 squared units.

Rectangle has length (l) same as base (b) of triangle i.e. l=7 and width (w=4).

Area of rectangle = l × w = 7 × 4 = 28 squared units.

Total area = 14 + 28 = 42 squared units.

So, final answer is 42 squared units.

Answer:

[tex]42[/tex] [tex]units^2[/tex]

Step-by-step explanation:

A simpler and faster way of solving this problem is through Pick's Theorem.

The theorem states that the area of any given shape (Specifically polygons) on a grid is the number of internal points (every point inside the shape) added to the quantity of the number of boundary points (Every point that is exactly on a point of the grid and is a part of the perimeter of the shape) divided by 2. Take this quantity and subtract 1 and it shows like so,

                                                  [tex]A=I+\frac{B}{2}-1[/tex].

In this case, we see that there are 36 internal points and 14 boundary points. So in turn, we get

                                                  [tex]A=36 + \frac{14}{2}-1\\A=36+7-1\\A=43-1\\A=\boxed{42}[/tex]

Hence giving our desired result of 42 square units.

In a direct variation equation, the graph passes through the origin (0,0). Every point on the graph can be represented as (kx, ky), where k is a constant.

In a direct variation equation, the graph passes through the origin (0,0). This means that when x=0, y=0. Every point on the graph can be represented as (kx, ky), where k is a constant. For example, if the direct variation equation is y = 2x, the graph would pass through (0,0), (1,2), (2,4), (3,6), and so on.

Answer:

23.08 %

Step-by-step explanation:

Markup price is the difference between the selling price and cost price of an item.

m = Markup = 30

s = Selling price = 130

[tex]\text{Markup percent on selling price}=\frac{m}{s}\times 100\\\Rightarrow \text{Markup percent on selling price}=\frac{30}{130}\times 100\\\Rightarrow \text{Markup percent on selling price}=23.08\ %[/tex]

∴ Markup percent on selling price is 23.08 %
