Answer: 14085 m^3.

Step-by-step explanation: To find the volume of a right rectangular prism, you need to multiply the length, width, and height.  The equation is below:

l x w x h = V where l is the length, w is the width, h is the height, and V is the volume of the right rectangular prism.

The length of this recycling bin is 9 meters, the width is 5 meters, and the height is 313 meters.  Now that we know the length, width, and height, we can substitute the variables with the information we've gathered.

9 x 5 x 313 = 14085.

Therefore, 14085 m^3 is your answer.

Have a great day! :)

Given parameters:

    Number that rode in columns = \(3\frac{2}{3}\) times the number that rode in rows.

       2200 rode in columns

Unknown:

Number of people that rode in rows = ?

Solution:

  Let the number of people that rode in columns  = C

   Let the number of people that rode in rows  = R

                 C = \(\frac{11}{3}\)R

Number of people that rode in rows  = 2200;

            2200 =  \(\frac{11}{3}\)R

             11R  = 2200 x 3

                R  = \(\frac{2200 x 3}{11}\)

                R = 200 x 3

We are provided with the information that the high temperature of 79°F occurs at 6 PM and the average temperature for the entire 24-hour period is 61°F.

We know that the high temperature of 79°F occurs at 6 PM, which corresponds to 18:00 in a 24-hour format. Since the average temperature for the 24-hour period is 61°F, we can use this as the midline of the sinusoidal function.

The general form of a sinusoidal function is:

f(x) = A(sin(B(x - C))) + D,

where A is the amplitude, B determines the period, C is the horizontal shift, and D is the vertical shift.

In this case, the midline is 61°F, so D = 61. Since the amplitude is half of the difference between the high and low temperatures, A = (79 - 61)/2 = 9°F. The period of a sinusoidal function representing a 24-hour period is 24, so B = [2π/24] = π/12.

To find the horizontal shift, we need to calculate the time difference between the high temperature at 6 PM and 7 AM. This is 7 + 12 - 18 = 1 hour. Since 1 hour is 1/24 of the period, the horizontal shift is C = π/12.

Now we can plug in the values into the equation:

f(x) = [9(sin((π/12))(x - π/12))] + 61.

To find the temperature at 7 AM (x = 7), we evaluate the equation:

f(7) = [9(sin((π/12))(7 - π/12)) ]+ [61] ≈ 51.3°F.

Therefore, the temperature at 7 AM is approximately 51.3°F.

The area of sector LMN is approximately 11.47 square units.

To find the area of a sector, we need to use the formula A = (θ/360)πr², where A is the area, θ is the central angle in degrees, and r is the radius of the circle.

In this case, the central angle is given as 84 degrees, and the radius is not explicitly given. However, we can find the radius by using the fact that the length of the arc is equal to the circumference of the circle multiplied by the ratio of the central angle to 360 degrees. The length of the arc can be found using the formula L = 2πr(θ/360).

Since the length of the arc is equal to the length of LM, which is 18 units, we can set up the equation as follows: 18 = 2πr(84/360).

Simplifying the equation, we have 9 = πr(84/360). Dividing both sides by π(84/360), we get r ≈ 9/(π(84/360)).

Now that we have the radius, we can substitute it into the formula for the area of a sector. The area is A ≈ (84/360)π(9/(π(84/360)))².

Simplifying further, A ≈ (84/360)(9/(π(84/360)))².

Calculating this expression, we find that A ≈ 11.47 square units (rounded to the nearest hundredth).

Therefore, the area of sector LMN is approximately 11.47 square units.

For the function f(x) = ⌊x²/3⌋, the values of f(s) for different sets s are as follows: a) f(s) = {1, 0, 0, 0, 1, 3}, b) f(s) = {0, 0, 1, 3, 5, 8}, c) f(s) = {0, 8, 16, 40}, d) f(s) = {1, 12, 33, 77}

The function f(x) = ⌊x²/3⌋ represents the floor of x²/3. To find f(s) for different sets s, let's evaluate it for each case:

a) For s = {-2, -1, 0, 1, 2, 3}:

  - For -2, (-2)²/3 = 4/3, and ⌊4/3⌋ = 1.

  - For -1, (-1)²/3 = 1/3, and ⌊1/3⌋ = 0.

  - For 0, (0)²/3 = 0/3 = 0.

  - For 1, (1)²/3 = 1/3, and ⌊1/3⌋ = 0.

  - For 2, (2)²/3 = 4/3, and ⌊4/3⌋ = 1.

  - For 3, (3)²/3 = 9/3 = 3.

  Therefore, f(s) = {1, 0, 0, 0, 1, 3}.

b) For s = {0, 1, 2, 3, 4, 5}:

  - For 0, (0)²/3 = 0/3 = 0.

  - For 1, (1)²/3 = 1/3, and ⌊1/3⌋ = 0.

  - For 2, (2)²/3 = 4/3, and ⌊4/3⌋ = 1.

  - For 3, (3)²/3 = 9/3 = 3.

  - For 4, (4)²/3 = 16/3, and ⌊16/3⌋ = 5.

  - For 5, (5)²/3 = 25/3, and ⌊25/3⌋ = 8.

  Therefore, f(s) = {0, 0, 1, 3, 5, 8}.

c) For s = {1, 5, 7, 11}:

  - For 1, (1)²/3 = 1/3, and ⌊1/3⌋ = 0.

  - For 5, (5)²/3 = 25/3, and ⌊25/3⌋ = 8.

  - For 7, (7)²/3 = 49/3, and ⌊49/3⌋ = 16.

  - For 11, (11)²/3 = 121/3, and ⌊121/3⌋ = 40.

  Therefore, f(s) = {0, 8, 16, 40}.

d) For s = {2, 6, 10, 14}:

  - For 2, (2)²/3 = 4/3, and ⌊4/3⌋ = 1.

  - For 6, (6)²/3 = 36/3 = 12.

  - For 10, (10)²/3 = 100/3, and ⌊100/3⌋ = 33.

  - For 14, (14)²/3 = 196

Step-by-step explanation:

The maximum strut load is 70.87 kN. The maximum strut load can be calculated using the following equation: Maximum strut load = 2 * unit weight * gravity * depth * sin(friction angle) * cos(friction angle)

In this case, the unit weight is 20 kN/m3, the gravity is 9.81 m/s^2, the depth is 7.5 m, and the friction angle is 36°. Plugging these values into the equation, we get the following:

Maximum strut load = 2 * 20 * 9.81 * 7.5 * sin(36°) * cos(36°) = 70.87 kN

Therefore, the maximum strut load is 70.87 kN.

The maximum strut load occurs at the first row of struts, which is installed at a depth of 0.5 m below ground surface. The strut load decreases with depth, and the maximum strut load is reached at the first row of struts.

The strut load is caused by the weight of the soil above the struts. The soil above the struts exerts a lateral force, which is resisted by the struts. The maximum strut load occurs when the lateral force is at its maximum.

The maximum strut load is an important design consideration for braced cuts. The strut load must be able to be safely carried by the struts. If the strut load is too high, the struts may buckle or fail.

the standard form of a quadratic function is

f(x) = ax² + bx + c ( a ≠ 0 )

the only function in this form from the list is

f(x) = - 5x² - 3x + 9

Answer:

f(x) = -5x² - 3x +9

Step-by-step explanation:

The standard form of a quadratic function is: f(x) = ax² + bx + c

The intercept form of a quadratic function is:  f(x) = a(x - p)(x - q)

The vertex form of a quadratic function is:  f(x) = a(x - h)² + k

(when a ≠ 0)

Therefore:

f(x) = -5x² - 3x +9

f(x) = -5(x + 4)(x - 2)

f(x) = 2x - 8

f(x) = -5(x - 1)² + 6

The sequence is neither arithmetic nor geometric.

Informally, a sequence in mathematics is a list of items that are in some order (or events). It possesses members, much like a set (also called elements, or terms). The length of the series is the number of ordered elements in the sequence, which could be unlimited.

Also, Arithmetic sequences, geometric sequences, quadratic sequences, and special sequences are the four primary categories of distinct sequences you need to be familiar with.

Squares, rectangles, circles, cones, cubes, and other shapes that can be created using geometry are known as geometric forms. In structural, civil, and architectural engineering, geometric forms are frequently used.

the trigonometric ratios of angle C in right triangle ABC are: sin(C) = 8/17,  cos(C) = 15/17, tan(C) = 8/15, csc(C) = 17/8, sec(C) = 17/15 and cot(C) = 15/8

To determine the trigonometric ratios of angle C in right triangle ABC, we can use the values of the sides AC and BC. Here's how we can find the trigonometric ratios:

Given: AC = 17 units and BC = 8 units

Using the Pythagorean theorem, we can find the length of side AB:

AB² = AC² - BC²

AB² = 17² - 8²

AB² = 289 - 64

AB² = 225

AB = 15 units

Now we have the lengths of all three sides of the triangle:

AC = 17 units

BC = 8 units

AB = 15 units

Using these values, we can find the trigonometric ratios:

1. Sine (sin) of angle C:

sin(C) = BC/AC

sin(C) = 8/17

2. Cosine (cos) of angle C:

cos(C) = AB/AC

cos(C) = 15/17

3. Tangent (tan) of angle C:

tan(C) = BC/AB

tan(C) = 8/15

4. Cosecant (csc) of angle C:

csc(C) = 1/sin(C)

csc(C) = 1/(8/17)

csc(C) = 17/8

5. Secant (sec) of angle C:

sec(C) = 1/cos(C)

sec(C) = 1/(15/17)

sec(C) = 17/15

6. Cotangent (cot) of angle C:

cot(C) = 1/tan(C)

cot(C) = 1/(8/15)

cot(C) = 15/8
