An irregular polygon is shown below:
The area of the irregular polygon is ___ square units.

Image of irregular polygon with length of 7 units and height of 3 units labeled on left side. Top side length of 4 units, the side adjacent to it on the right is 2 units.

Answer:

a. y = 3x² + 9x +6

d. y = x(3x + 10)

Step-by-step explanation:

Most equations that have a squared variable are going to be nonlinear.

If you distribute the x in the d equation you get this: y = 3x² + 10x

Choices b, c, and e are going to be linear because there is only one variable, and those variables do not have exponents.

Answer:

x=17°

Step-by-step explanation:

The opposite angles, will always be the same. so the the angle across from 163° will be 163

so 163°-x°=180°

Because straight angles = 180°

You'd get x°=17°

Answer:

(n÷-6)-10 = -2

n = -48

Step-by-step explanation:

let 'n' = number

(n÷-6)-10 = -2

[tex]\frac{n}{-6}[/tex] - [tex]\frac{60}{6}[/tex] = -2

[tex]\frac{(-n-60)}{6}[/tex] = -2

multiply each side by 6 to get:

-n-60 = -12

-n = 48

n = -48

The question is an illustration of a linear function and an exponential function.

The given parameters are:

Calculate Company

Initial net income: $8 million

Rate: $0.5 million per year

Computate Company

Initial net income: $3 million

Rate: 20% each year

The model of calculate company is best represented using a linear function, while the computate is best modeled by an exponential function.

A linear function is represented as:

[tex]y = mx + b[/tex]

Where:

An exponential function is represented as:

[tex]y = a(1 + r)^x[/tex]

Where:

So, the functions are:

[tex]y=8 + 0.5x[/tex] --- calculate company

[tex]y =3(1.2)^x[/tex] --- computate company

See attachment for the graph of both functions

From the graph of both functions, we have the following comparison:

In (b), we concluded that:

The computate company follows a more realistic model

Hence, it is better to invest in the computate company

From the attached graph, both functions meet at approximately (8, 12)

This means that they have the same net income in 2018

The graphs do not meet again.

This means that, they would never have the same net income again

Answer:

340 ft²

Step-by-step explanation:

From the diagram, we can see that the shape is made up of a square and 4 triangles. (We know it's a square as its width equals its length).

First, find the area of the square.

Area of a square = width x length = 10 x 10 = 100 ft²

All the triangles are the same, so we need to find the area of one of the triangles and multiply it by 4.

Area of a triangle = 1/2 x base x height = 1/2 x 10 x 12 = 60 ft²

So the total area of all 4 triangles = 4 x 60 = 240 ft²

Therefore the total surface area = 100 + 240 = 340 ft²

Answer:

340 ft²

Step-by-step explanation:

The surface area of a shape is basically the area of its faces.

[tex]\rightarrow \text{Surface area of pyramid: 4(Area of triangle) + Area of square}[/tex]

1. First, Let's find the area of the triangles. To find the area of a triangle, we need to multiply the height and the base and then divide the product by 2.

[tex]\rightarrow \text{Area of triangle} = \dfrac{12 \times 10}{2}[/tex]

Now, let's find the area of the triangle by simplifying the RHS.

[tex]\rightarrow \text{Area of triangle} = 6 \times 10[/tex]

[tex]\rightarrow \text{Area of triangle} = 60 \ \text{ft}^{2}[/tex]

Since there are four triangles, we need to further multiply the area of the triangle by 4 to find the area of four triangles.

[tex]\rightarrow \text{Area of four triangles} = 4(60)[/tex]

[tex]\rightarrow \text{Area of four triangles} = 240 \ \text{ft}^{2}[/tex]

2. Now, let's find the area of the square. To find the area of the square, we need to square the side length.

[tex]\rightarrow \text{Side length} = 10 \ \text{ft}[/tex]

[tex]\rightarrow \text{Area of square} = 10^{2}[/tex]

[tex]\rightarrow \text{Area of square} = 100 \ \text{ft}^{2}[/tex]

3. Lastly, let's find the surface area. To find the surface area of the figure, we need to sum up the area of the triangles and the area of the square.

[tex]\rightarrow \text{Surface area of pyramid: 4(Area of triangle) + Area of square}[/tex]

[tex]\rightarrow \text{Surface area of pyramid: 240 + 100}[/tex]

[tex]\rightarrow \text{Surface area of pyramid: 340 \text{ft}}^{2} }[/tex]

Answer:

90

Step-by-step explanation:

First, let's make a line of separation to make a rectangle and triangle.

Now, we know the area of a rectangle is l × w, where l = length and w = width. The length and width of this rectangle is is 8 and 9, so 8 × 9 = 72.

Next, the area of a triangle is bh ÷ 2, where b = base and h = height. We're given the base of the triangle as 9 m. To find the height, we subtract 8 from 12 and get 4. 9 multiplied by 4 is 36, and 36 divided by 2 is 18.

Lastly, we combine the area of the rectangle and triangle. 72 + 18 = 90.

Therefore, the answer is 90 m^2.

keeping in mind that parallel lines have exactly the same slope, let's check for the slope of the equation above

[tex]y=\stackrel{\stackrel{m}{\downarrow }}{\cfrac{2}{3}}x+5\qquad \impliedby \begin{array}{|c|ll} \cline{1-1} slope-intercept~form\\ \cline{1-1} \\ y=\underset{y-intercept}{\stackrel{slope\qquad }{\stackrel{\downarrow }{m}x+\underset{\uparrow }{b}}} \\\\ \cline{1-1} \end{array}[/tex]

so we're really looking for the equation of a line whose slope is 2/3 and passes through (-3 , 8)

[tex](\stackrel{x_1}{-3}~,~\stackrel{y_1}{8})\qquad \qquad \stackrel{slope}{m}\implies \cfrac{2}{3} \\\\\\ \begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-\stackrel{y_1}{8}=\stackrel{m}{\cfrac{2}{3}}(x-\stackrel{x_1}{(-3)}) \\\\\\ y-8=\cfrac{2}{3}(x+3)\implies y-8=\cfrac{2}{3}x+2\implies y=\cfrac{2}{3}x+10[/tex]
