Which of the following fall between 12 and 13?

The measure of the diagonal of the rectangular garden will be 7.2 feet. Then the correct option is a.

It is a polygon with four sides. The total interior angle is 360 degrees. A rectangle's opposite sides are parallel and equal, and each angle is 90 degrees. Its diagonals are all the same length and intersect in the centre.

Landon has a rectangular garden with an area of 24.7 square feet. If the length of the garden is 5.7 feet.

Then the width of the garden will be

Area = Length x Width

24.7 = 5.7 x  W

 W = 4.33

Then the measure of the diagonal of the rectangular garden will be

D² = L² + W²

D² = 5.7² + 4.33²

D² = 32.49+ 18.74

D² = 51.23

D = 7.2

D ≅ 7.2 feet

Thus, the correct option is a.

Answer:

[tex] - 8x + 6y = - 22 \\ - 4x + 4y = - 4 \\ .............................................. \\ - 12x + 10y = - 26 \\ - 2(6x - 5y) = - 26 \\ 6x - 5y = 13[/tex]

Answer: 637 m²

Step-by-step explanation:

   We need to find the area of four triangles and one square.

   The square: 169 m²

A = L²

A = (13 m)²

A = 169 m²

   The triangles: 468 m²

-> We have four congruent triangles. I will find the area of two (skipping the "divide by two" part of the formula) and multiply by two to find all four at once.

A = B * H

A = (13 m) * (18 m)

A = 234 m²

-

234 m² * 2 = 468 m²

   Total surface area:

169 m² + 468 m² = 637 m²

Answer:

29 students

Step-by-step explanation:

Hello!

When expressed that the ratio of Teachers to Students is 2:29, the ratio is in the format Teachers: Students.

That means, for every 2 teachers, there are 29 students.

Ratio:

2(teachers): 29(students)

There are 29 students for 2 teachers.

We can also find the number of students for 4 teachers by simply multiplying both sides by 2

The surface area of the figures are;

Rectangle = 36.2 yd^2

Cuboid = 200 ft^2

Parallelogram = 27.8 cm^2

Cylinder = 138 yd^2

We can be able to obtain the surface area of various figures by the use of formulas.

For the rectangle, the surface area is = 7.1 yd * 5.1 yd = 36.2 yd^2

For the cuboid, the surface area = 2[(8 ft * 14 ft) + (4 ft * 8ft) + (14ft * 4 ft)] = 200 ft^2

For the parallelogram, the surface area = 5.4 cm * 5.14 cm = 27.8 cm^2

For the cylinder, the surface area is; (2 * 3.14 * 4^2) + (2 * 3.14 * 4 * 6) = 138 yd^2

Answer:

y = 1.8x, where time is the independent variable, x, and distance is the dependent variable.

Step-by-step explanation:

The independent variable is along the x-axis.

The dependent variable is along the y-axis.

Therefore,

Equation of the line

To find the equation of the line, define two points on the line:

Use the slope formula to find the slope (m) of the line:

[tex]\implies \textsf{slope}\:(m)=\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{9-0}{5-0}=1.8[/tex]

From inspection of the graph, the y-intercept is at (0, 0).

Point-slope form of a linear equation:  [tex]y = mx + b[/tex]

Substitute the found slope and y-intercept into the formula to create the equation of the line:

[tex]\implies y=1.8x+0[/tex]

[tex]\implies y=1.8x[/tex]

Conclusion

y = 1.8x, where time is the independent variable, x, and distance is the dependent variable.

Answer:

[tex]y = -\frac{3}{4} sin(\frac{2}{3}x)[/tex]

Step-by-step explanation:

First determine whether it is a sine function or a cosine function. Since

sin(x) = 0 at x = 0 and we see indeed that the value of the function is 0 at x = 0 it must be a sine function

The general equation of a sine function is [tex]a sinbx[/tex]

where a is the amplitude. The amplitude is one-half the difference between the lowest and highest values in the graph.From the graph we can see that the highest value is 3/4 and lowest is -3/4 so the amplitude = 1/2 (3/4 + 3/4) = 3/4

If the amplitude were positive, the function would be increasing at (0,0) and going up to its amplitude value. However we can see that the function is decreasing at (0,0 ) and goes down to -3/4. Therefore the amplitude a has a negative sign so a = -3/4

To compute b, note that the period of the function ie where it finishes a full cycle is 3π since the function at that x value repeats itself. The relationship between b and the period is 2π/b = 3π in this particular case

This gives b = 2/3

So a = -3/4, b = 2/3 and the equation is [tex]y = -\frac{3}{4} sin(\frac{2}{3}x)[/tex]

7g - 6 = -20

Add 6 to both sides

Step-by-step explanation:

7 negative 2's equals negative 14, minus 6 equals negative 20.

Step-by-step explanation:

a.

x = number of matching questions

y = number of essay questions

x >= 3

x <= 12

y >= 4

y <= 15

x + y <= 20

the delimiter lines are therefore

x = 3

x = 12

y = 4

y = 15

y = 20 - x

when you graph these lines, the corners (intersection points) of the inner shaded area are

(3, 4)

(12, 4)

(3, 15)

(12, 8)

(5, 15)

the other intersection points

(12, 15)

(3, 17)

(16, 4)

are outside the inner shaded area.

b.

10x + 25y = score

and this we want to maximize.

we have to try the 5 corners from a. and see, which one gives the maximum score.

(3, 4) gives

10×3 + 25×4 = 30 + 100 = 130

(12, 4) gives

10×12 + 25×4 = 120 + 100 = 240

(3, 15) gives

10×3 + 25×15 = 30 + 375 = 405

(12, 8) gives

10×12 + 25×8 = 120 + 200 = 320

(5, 15) gives

10×5 + 25×15 = 50 + 375 = 425

that is the most.

so, Phil should do 5 matching questions and 15 essay questions for maximum score.

Step-by-step explanation:

Answer:

b) f(x) = x² - 256

Step-by-step explanation:

Since we have been given the zeros of a function, -16 and 16. We are asked to find which function truly has those zeros.

To find this, we can substitute the zeros for x in the functions to find the one that is true/correct.

A) f(x) = x² - 16

 ⇒  0 = 16² - 16          and          ⇒  0 = (-16)² - 16

 ⇒  0 = 256 - 16        and          ⇒  0 = 256 - 16

 ⇒  0 = 240 ✘          and          ⇒  0 = 240 ✘

B) f(x) = x² - 256

 ⇒  0 = 16² - 256          and          ⇒  0 = (-16)² - 256

 ⇒  0 = 256 - 256        and          ⇒  0 = 256 - 256

 ⇒  0 = 0 ✔                  and          ⇒  0 = 0 ✔

C) f(x) = x² - 32x + 256

 ⇒  0 = 16² - 32(16) + 256         and        ⇒  0 = (-16)² - 32(-16) + 256

 ⇒  0 = 256 - 512 + 256           and        ⇒  0 = 256 + 512 + 256

 ⇒  0 = 512 - 512                       and        ⇒  0 = 512 + 512

 ⇒  0 = 0 ✔                               and        ⇒  0 = 1,024 ✘

D) f(x) = x² + 32x + 256

  ⇒  0 = 16² + 32(16) + 256         and        ⇒  0 = (-16)² + 32(-16) + 256

  ⇒  0 = 256 + 512 + 256           and         ⇒  0 = 256 - 512 + 256

  ⇒  0 = 512 + 512                       and         ⇒  0 = 512 - 512

  ⇒  0 = 1,024 ✘                          and        ⇒  0 = 0 ✔

Therefore, Function B has the zeros of x = -16 and x = 16.

Answer:

A. x = 5 and x = 6

Step-by-step explanation:

What are zeroes?

Zeroes are simply the x intercepts of a function or the coordinates where the function crosses the x axis

Finding the zeroes.

By looking at the graph, we can say that the function crosses the x axis at (5,0) and (6,0).

This means the x intercepts / zeroes are at x = 5 and x = 6 so the answer is A

Step-by-step explanation:

x² - 12x + 32 = 0

the goal is the vertex form : a form like

(x - h)² + k = r²

with (h, k) being the vertex or center and r the radius.

doing all the multiplications we get

x² - 2hx + h² + k - r² = 0

and we compare this with our original equation. we see

x² = x²

-12x = -2hx

-12 = -2h

6 = h

32 = h² + k - r²

32 = 36 + k - r²

-4 = k - r²

possible solution : k = 0 and then r = 2

but also e.h. k = 12, r = 4

so, without the information about e.h. the radius we cannot identify one solution.

so, "A" vertex form (one of many possible ones) is

(x - 6)² = 4

It will take 0.556 seconds for an echo to reach one's ears

From the question, we are to determine how long it would take an echo to reach one's ears

From the formula,

[tex]Speed = \frac{2 \times distance \ travelled\ by \ sound}{Time}[/tex]

NOTE: To hear an echo, the sound will travel to and fro, hence, it will cover twice the distance

From the given information,

Distance = 92.0 m

NOTE: Speed of sound in air at 0 °C ≅ 331 m/s

Putting the parameters into the formula, we get

[tex]331 = \frac{2 \times 92.0}{Time}[/tex]

[tex]Time = \frac{2 \times 92.0}{331}[/tex]

Time = 0.556 secs

Hence, it will take 0.556 seconds for an echo to reach one's ears.

The vertical asymptote is x = 1 and the horizontal asymptote is y = -1 if the equation of the hyperbola is f(x)=−3/x−1 −1

It's a two-dimensional geometry curve with two components that are both symmetric. In other words, the number of points in two-dimensional geometry that have a constant difference between them and two fixed points in the plane can be defined.

We have the equation of the hyperbola:

[tex]\rm f(x)=\dfrac{-3}{x-1} -1[/tex]

The asymptotes will be

Vertical asymptote:        x -1 = 0 ⇒ x = 1

Horizontal asymptote:   y + 1= 0 ⇒ y = -1

Thus, the vertical asymptote is x = 1 and the horizontal asymptote is y = -1 if the equation of the hyperbola is f(x)=−3/x−1 −1
