Step-by-step explanation:

x is a variable or a multiplication sign

Answer: range: (-10,-4,4,10)

Step-by-step explanation:  range is y value and domain is x value

f(x) will be ur y

in place  of x put the value of domain

example:

             y=2(-2)-6

           = -10

2) y=2[1]-6

     = -4

like that do the rest of the working to find ur range.

Answer:

the range is : (-10,-4,4,10)

Step-by-step explanation:

calculate :

f(-2) = 2(-2) -6 = -10

f(1) = 2(1) -6 = -4

f(5) = 2(5) -6 = 4

f(8) = 2(8) -6 = 10

the range is : (-10,-4,4,10)

Answer:

[tex]011\degree[/tex]

Step-by-step explanation:

The direction of a vector is given by;

[tex]\theta=\tan^{-1}(\frac{y}{x})[/tex]

The given vector is <5,1>.

The x-component of this vector is 5 and the y-component is 1.

We substitute the values into the formula to obtain;

[tex]\theta=\tan^{-1}(\frac{1}{5})[/tex]

We use our scientific calculator to obtain;

[tex]\theta=11.3099[/tex]

Therefore the direction of the given angle is [tex]011\degree[/tex] to the nearest degree.

Answer:

The correct option is 1.

Step-by-step explanation:

It is given that the box plot shows the number of books sold each day at a store for 80 days.

A box plot is drawn with end points at 0 and 16.  It means minimum value is 0 and maximum is 16.

The box extends from 2 to 12. It means first quartile is 2 and the third quartile is 12. A vertical line is drawn inside the box at 7, it means median is 7.

He have to find the number of days in which the bookstore sell 2 to 12 books.

2 is first quartile and 12 is third quartile, we know that

[tex]Q_1=25\%[/tex]

[tex]Q_3=75\%[/tex]

[tex]Q_3-Q_1=75\%-25\%=50\%[/tex]

The data lies between Q₁ and Q₃ is 50% of the data.

[tex]80\times \frac{50}{100}=40[/tex]

The bookstore sell 2 to 12 books in 40 days.

Therefore, the correct option is 1.

Answer:

I had to do this and i got option  1, too (40)

To graph y = |x+2|, consider the parent function y = |x| and translate it 2 units to the left. Choose x-values, find the corresponding y-values, and plot the points. Connect the plotted points to obtain the graph of y = |x+2|.

To graph the equation y = |x+2|, we will first consider the parent function y = |x|, which is a V-shaped graph that passes through the origin. Translating the graph y = |x| to the left by 2 units gives us y = |x+2|.

To plot the graph, we can choose various x-values and find the corresponding y-values. For example, when x = -4, y = |(-4)+2| = 2. Similarly, when x = -2, y = |(-2)+2| = 0. We can continue this process to find more points and then plot them on a coordinate plane.

By connecting the plotted points, we will obtain the graph of y = |x+2| which will be a V-shaped graph shifted 2 units to the left.

ANSWER

There is

[tex]3.219\times {10}^{5} [/tex]

more money in the vault in the evening than in the morning.

EXPLANATION

The amount of money in the vault in the morning is

[tex]2.81 \times {10}^{4} [/tex]

The amount of money in the vault at the end of the day is:

[tex] 3.5 \times {10}^{5} [/tex]

To find how much more money is in the vault at the end of the day than there was in the morning, we subtract to get:

[tex]3.5 \times {10}^{5} - 2.81 \times {10}^{4} [/tex]

[tex] = 3.5 \times 100000 - 2.81 \times 10000[/tex]

[tex]350000 - 28100= 321900[/tex]

Therefore, there is

[tex]3.219\times {10}^{5} [/tex]

more money in the vault.

A rectangular prism with three different whole number dimensions has the same volume will be 1 cm by 5 cm by 25 cm.

It deals with the size of geometry, region, and density of the different forms both 2D and 3D.

The volume of a cube is 125 cubic centimeters.

A rectangular prism with three different whole number dimensions has the same volume.

Then the dimension of the rectangular prism will be

Answer:

Step-by-step explanation:

n, n + 1, n + 2 - three consecutive integers

The equation:

n(n + 1) = 8(n + 2) + 2              ust the distributive property

n² + n = 8n + 16 + 2

n² + n = 8n + 18               subtract 8n from both sides

n² - 7n = 18          subtract 18 from both sides

n² - 7n - 18 = 0

n² - 9n + 2n - 18 = 0

n(n - 9) + 2(n - 9) = 0

(n - 9)(n + 2) = 0 ⇔ n - 9 = 0 or n + 2  =0

n - 9 = 0     add 9 to both sides

n = 9

n + 2 = 0          subtract 2 from both sides

n = -2 < 0

n + 2 = 9 + 2 = 11

Answer:

8

Step-by-step explanation:

The sum of the internal angles of a polygon is

sum = 180° (n - 2) ← n is the number of sides

here n = 5, hence

sum = 180° × 3 = 540°

Each exterior angle plus interior angle = 180°

Subtract each exterior angle from 180 for corresponding interior angle.

180 - 59 = 121, 180 - 77 = 103, 180 - 66 = 114, 180 - 62 = 118

Sum the 4 interior angles and subtract from 540 for 5 th interior angle

5 th = 540° - (121 + 103 + 114 + 118)° = 540° - 456° = 84°

The 5 th interior angle and 12x sum to 180 ( same reason as above )

Hence

12x + 84 = 180 ( subtract 84 from both sides )

12x = 96 ( divide both sides by 12 )

x = 8

Answer:

width is 48, length is 60

Step-by-step explanation:

Answer:  The dimensions of the field are

width = 40 ft and length = 60 ft.  

Step-by-step explanation:  Given that a field with an area of 2880 ft² has the shape of a rectangle with length 12 ft larger than the width.

We are to find the dimensions of the field.

Let w ft be the width of the given rectangular field.

Then, the length of the field will be (w + 12) ft.

According to the given information, we have

[tex]w \times (w+12)=2880\\\\\Rightarrow w^2+12w=2880\\\\\Rightarrow w^2+12w-2880=0\\\\\Rightarrow w^2+60w-48w-2880=0\\\\\Rightarrow w(w+60)-48(w+60)=0\\\\\Rightarrow (w-48)(w+60)=0\\\\\Rightarrow w-48=0,~~~w+60=0\\\\\Rightarrow w=48,-60.[/tex]

Since the measure of a side of a rectangle cannot be negative, so w = 48.

This implies that

length of the field = w + 12 = 48 + 12 = 60 ft.

Thus, the dimensions of the field are

width = 40 ft and length = 60 ft.

r - (r x .45) = d (The discounted price of the dress.)

Step-by-step explanation:

The distance of a run compared with the number of times around a track.

The question asks for what is most likely to have a constant rate of change. This means that for every x, there is about the same y, as a constant rate of change means that there is a consistent slope, which is the x and y value. In real world terms, it means that you can expect every one value to change however much without changing randomly.

For example, when you buy a pizza, you expect a pizza to get you 8 slices. When you get two, you expect to get 16, 3 gets you 24 slices, and so on. This expectation is based off the constant rate of change, as you get 8 slices for each pizza. The slices would be modeled as y and the pizza would be modeled as x in mathematical terms in this situation.

Because we know that the track's distance doesnt change with every lap, we can expect it to have a constant rate of change. This concept is the same as the pizza as discussed earlier. Every lap would get her a certain amount of miles, and every other lap would increase the same amount.
