Step-by-step explanation: The answer is 4 all u do is add 2 to 2

Answer: 2+2=4

Step-by-step explanation: The sum of two and two results in a value of four in a quantitative analysis.

The quadratic polynomial with integer as coefficients that has four real roots including these conjugates is a² + b² - 2ab - 20a - 20b + 88 ≥ 0

One possible quartic polynomial with integer coefficients that has four real roots, including the conjugates 5+√3 and 5-√3, is:

(x - 5 - √3)(x - 5 + √3)(x - a)(x - b)

where a and b are the remaining two roots.

Expanding the first two factors using the difference of squares formula, we get:

(x - 5)² - 3

Expanding the last two factors, we get:

x² - (a + b)x + ab

Putting it all together, the quartic polynomial is:

a² + b² - 2ab - 20a - 20b + 88 ≥ 0

To ensure that a and b are also real, we can use the fact that the discriminant of a quadratic equation ax² + bx + c = 0 with real coefficients is b² - 4ac ≥ 0. Applying this to the quadratic factor in the above polynomial, we get:

(a + b)² - 4ab ≥ 0

Expanding and simplifying, we get:

a² + b² - 2ab - 20a - 20b + 88 ≥ 0

To simplify the problem, we can set a = b, since the polynomial is symmetric with respect to the roots. Then, the inequality becomes:

2a² - 40a + 88 ≥ 0

Dividing by 2 and factoring, we get:

(a - 10)² - 12 ≥ 0

This inequality is always true for real values of a, so we can choose any real value for a and set b = a to obtain a quartic polynomial with integer coefficients that has four real roots, including the conjugates 5+√3 and 5-√3.

The domain can be written as follows:

R - {x = n*12pi or m*4pi | n, m ∈ Z}

where pi = 3.14 and R is the set of real numbers.

Here we want to find the domain of the function:

y = tan(x/8)

The tangent is the quotient between the cosine and the sine, then we will get:

sin(x/8)/cos(x/8)

The problems of the tangent are all the values that make the denominator equal to zero, then we need to remove these.

The zeros are:

cos(x/8) = 0

We know that cos(pi/2) = cos(3pi/2)  = 0

Then:

x/8 = pi/2

x = 4pi

x/8 = 3pi/2

x = 12pi

The surface area of the figure is  174.7 sq. ft.

Consider the bottom rectangular surface of the figure.

The dimensions of the bottom rectangular surface are: length = 10 ft and width = 3 ft

Using the formula for the area of rectangle, the area of bottom surface of the figure would be,

A₁ = length × width

A₁ = 10 × 3

A₁ = 30 sq. ft.

The dimensions of the right rectangular surface are length = 9 ft and width = 3 ft

Using the formula for the area of rectangle, the area of bottom surface of the figure would be,

A₂ = length × width

A₂ = 9 × 3

A₂ = 27 sq. ft.

The dimensions of the left rectangular surface are length = 11 ft and width = 3 ft

Using the formula for the area of rectangle, the area of bottom surface of the figure would be,

A₃ = length × width

A₃ = 11 × 3

A₃ = 33 sq. ft.

Answer: Option C.

The volume of a cylinder is given by the formula V = πr^2h, where r is the radius and h is the height.

Given that the diameter of the container is 24 ft, the radius (r) would be half of that, which is 12 ft.

The depth of the container (h) is given as 4 ft.

Plugging in these values into the formula, we get:

V = π(12^2)(4)

V = 3.14(144)(4)

V = 1808.6 cubic feet (rounded to the nearest tenth)

So, the storage container can hold approximately 1808.6 cubic feet of wood, rounded to the nearest tenth.

As per the unitary method, each piece is 3.25 meters long by dividing the total length of the ribbon by the number of pieces.

Larry has cut a ribbon into 8 equal pieces. The total length of the ribbon is 26 m. We need to find out the length of each piece of the ribbon.

To do this, we can use the unitary method. We know that the ribbon is divided into 8 equal pieces, so each piece is 1/8th of the total length of the ribbon.

Therefore, we can find the length of each piece by dividing the total length of the ribbon by 8:

Length of each piece = Total length of ribbon / Number of pieces

Length of each piece = 26 m / 8

Length of each piece = 3.25 m

So, each piece of the ribbon is 3.25 meters long.

We used the unitary method by finding the value of one unit (1/8th of the ribbon) and then using it to calculate the value of other units (the length of each piece).

The outputs for industries X and Y will be 31 million and 43.2 million, respectively  supposedly the final demand changes to 20 for X and 30 for Y.

We will  start with industry X.

The final demand for X hade an increment from 14 million to 20 million with  an increase of 6 million, hence the final output of X must also increase by 6 million to make up for demand.

Users    Final    Producers

Demand     X          Y

X          14         7

Y           6        18

Total     20        25

The table tells us that for every additional million of final demand for X, the producers in industry X need to produce 0.5 million of output.

So the new total output for industry X is 28 + 3 = 31 million.

For  industry Y

The same scenario occurred for Industry Y which had final output of 12 in order to meet the demand increment.

So the new total output for industry Y is 36 + 7.2 = 43.2 million.

The evaluated speed of P is 54.5 m s¯¹, under the condition that two forces F₁ and F₂ act on a particle P. The force F₁ is given by F₁ = (-i + 2j) N and F₂ acts in the direction of the vector (i + j).

To evaluate the speed of particle P when t = 3 seconds, we can apply the equations of motion formulas to calculate the velocity if the acceleration and initial velocity values are already given.
The formula can be derived :
v = u + at
Here,
v =  final velocity of the particle,
u = initial velocity of the particle,
a = acceleration acting on the particle
t = time taken.
It is known to us that the acceleration of P is (3i + 9j) ms² and at time t = 0, the velocity of P is (31 -22j) m s¯¹. We can evaluate the initial velocity u by taking the magnitude of (31 -22j) that is
√(31² + (-22)²)
= 39.051 m s¯¹.
Now we can staging all values into the formula
v = u + at
v = 39.051 + (3i + 9j) × 3
v = 39.051 + (9i + 27j)
v = (39.051 + 9)i + (27)j
v = 48.051i + 27j
Then, when t = 3 seconds, the speed of particle P is √(48.051² + 27²)

When a tank is 1/2 full it contains 45 liters of water, the area of the base is 450 cm², the height of the tank is 200 cm.

Let the height of the tank be 'h' cm. Since the tank is half full, it contains 45 liters of water which is equal to 45,000 cubic cm.

The volume of water in the tank is given by:

Volume of water = (1/2) x (450 cm²) x (h cm)

Since the volume of water is 45,000 cubic cm, we can set up the following equation:

(1/2) x (450 cm²) x (h cm) = 45,000 cubic cm

Simplifying, we get:

225h = 45,000

h = 200 cm
