Answer:

the answer of the above question is -1.2

the speed of the bus in meters per second is 8.33 m/s. If a bus travels a distance of 1 kilometer in 2 minutes, we can use the formula for speed to calculate its speed in meters per second (m/s).

The formula for speed is:

Speed = Distance ÷ Time

Here, the distance is 1 kilometer, which is equal to 1000 meters (since 1 kilometer = 1000 meters), and the time is 2 minutes, which is equal to 120 seconds (since 1 minute = 60 seconds).

So, we can plug these values into the formula:

Speed = 1000 meters ÷ 120 seconds

Simplifying this expression, we get:

Speed = 8.33 meters per second (rounded to two decimal places)

Therefore, the speed of the bus in meters per second is 8.33 m/s.

To put this into context, it's important to understand that speed is the rate at which an object moves, while velocity is the rate at which it moves in a specific direction. So, in this case, we have only calculated the speed of the bus, not its velocity. However, knowing the speed of the bus can be useful for a variety of applications, such as determining how long it will take to travel a certain distance, or calculating the fuel efficiency of the vehicle

The given problem includes communicating divergence and curl equations in different coordinate frameworks, for example, tube-shaped, round, and symmetrical curvilinear coordinates.

(a) The expression O_ij,j which is the divergence of the tensor can be written in cylindrical coordinates as follows:

O_ij,j =  (1/r (rO_rr)/r), (1/r (O_/)), (1/r (O_zz/z)), (1/r (O_rr/r)), (1/r (O_/)), and (1/r (O_zz/z)).

The expression O_ij,j in spherical coordinates can be written as:

O_ij,j = ((1/r^2)(∂(r^2O_rr)/∂r)) + ((1/(r sinθ))(∂(sinθO_θθ)/∂θ)) + ((1/(r sinθ))(∂O_φφ/∂φ)) + ((1/r^2)(∂(r^2O_rr)/∂r)) + ((1/(r sinθ))(∂(sinθO_θθ)/∂θ)) + ((1/(r sinθ))(∂O_φφ/∂φ)).

(b) While thinking about the articulation O_ij,j - M_ij,k in symmetrical curvilinear arranges, and applying it to the specific instance of circular facilitates, the equation becomes:

(1/r2)(r2O_rr)/r) + (1/r sin)(sin O_)/) + (1/r sin)(O_/) - (M_rr/r) - (1/r)(M_/) - (1/r sin)(M_/)

c) If we assume that divO + V = (divU) 0, we can express this relationship in cylinder coordinates as follows:

V_r(U_r/r) + V_(1/r)(U_/) + V_z(U_z/z) = 0. (1/r)(rO_rr)/r) + (1/r)(O_/) + (O_zz/z)

In circular coordinate the connection becomes:

(1/r2)(r2O_rr)/r) + (1/r sin)(sin O_)/) + (1/r sin)(O_/) + V_r(U_r/r) + V_(1/r)(U_/) + V_(1/r sin)(U_/) = 0.

Answer:

I think it might be 56 degrees

Answer: 216.77

Step-by-step explanation:

The maximum number of people that could be helped with one plane of supplies is 40,000.

To determine the maximum number of people that can be helped, we need to consider the weight and volume constraints of the plane. Each food kit helps 10 people and weighs 20 pounds, while each medicine kit helps B people and weighs 10 pounds. The weight constraint of the plane is 80,000 pounds, and the volume constraint is 6,000 cubic feet.

To optimize the usage of weight and volume, we need to find the combination of food kits and medicine kits that maximizes the number of people helped. Since each food kit and medicine kit has a weight of 20 pounds and 10 pounds respectively, we can calculate the maximum number of kits based on the weight constraint. The maximum number of food kits is 80,000 pounds / 20 pounds = 4,000 kits. Similarly, the maximum number of medicine kits is 80,000 pounds / 10 pounds = 8,000 kits.

Next, we consider the volume constraint. Since each kit occupies 1 cubic foot of volume, the maximum number of kits based on volume is 6,000 cubic feet.

To determine the maximum number of people helped, we need to find the minimum value between the maximum number of food kits and the maximum number of medicine kits. In this case, the minimum value is 4,000 kits. Therefore, the maximum number of people helped is 4,000 kits * 10 people per kit = 40,000 people.

Thus, the maximum number of people that could be helped with one plane of supplies is 40,000.

The polynomial 2x³ − 5x² + 6x − 15 as a product of binomials is option (a) (x² + 3)(2x − 5).

To factor the polynomial 2x³ − 5x² + 6x − 15 into a product of binomials, we can use the technique of polynomial factorization by grouping.

Factor out the greatest common factor (GCF) from the first two terms and the last two terms separately

2x³ − 5x² + 6x − 15 = x²(2x − 5) + 3(2x − 5)

Notice that we have a common binomial factor of (2x − 5) in both terms. Factor out this common binomial factor

2x³ − 5x² + 6x − 15 = (2x − 5)(x² + 3)

Therefore, the polynomial 2x³ − 5x² + 6x − 15 can be factored as the product of binomials (2x − 5) and (x² + 3).

So, the correct option is (a) (x² + 3)(2x − 5).

When the above is simplified using Boolean Algebra, we have F = x' + y' + w'xy.

We can simplify  the Boolean function F = xy'z' + xy'z+ w'xy +   w'x'y' + w'xy using the following Boolean Algebra rules.

Absorption - x + xy = x

Commutativity -  xy = yx

Associativity - x(yz) = (xy)z

Distributivity - x(y + z) = xy + xz

Using the above , we   have

F = xy'z' + xy'z+ w'xy + w'x'y' +   w'xy

= xy'(z + z') + w'xy(x + x')

= xy' +  w'xy

= (x' + y)(x' + y')  + w'xy

= x' + y' + w'xy

Jada's rectangular piece of paper with an area of 20 square inches is larger than Han's paper sector.

To compare the sizes of the two pieces of paper, we need to compare their areas.

Jada's rectangular piece of paper has an area of 5 x 4 = 20 square inches.

Han's paper sector is a fraction of a circle with radius 5 inches. The arc length of this sector can be calculated using the formula:

Arc length = (angle/360) x 2πr

where r is the radius of the circle, and angle is the central angle of the sector in degrees. Han did not provide the angle, so we cannot calculate the arc length and compare the areas of the two pieces of paper.

However, we can say that Han's paper sector will have an area less than or equal to the area of the circle with radius 5 inches. The area of a circle is given by the formula:

Area = πr^2

So, the area of the circle with radius 5 inches is:

Area = π x 5^2 = 25π square inches

Since the sector is a fraction of the circle, its area will be less than or equal to 25π square inches. Therefore, Jada's rectangular piece of paper with an area of 20 square inches is larger than Han's paper sector.

In mathematics, a graph is defined as a graphical representation or diagram that organizes facts or values. The graph's points frequently reflect the relationship between two or more objects.

In order to solve for the above values, the best way is to spot the function that exists in the graph which is given as:

F(y) = 3.5x

In the first table, where x = 2

y= 3.5 *2

= 7

This iteration goes on and on and is consistent for all the values.

In the second table,

Where F(y) is known, for example 10.5, then x is derived as:

10.5 = 3.5x (divide both sides by 3.5)

x = 3

This iteration goes on and on and is consistent for all the values.

In the third table, we simply swap the values back and forth using the function F(y) = 3.5x to derive all values.

Answer:

$261.80 Net pay

Step-by-step explanation:

340 x 0.23 =   $78.20 in taxes

$340 - $78.20 =  $261.80 Net pay

Answer:

$261.8 Is how much you take home.

Step-by-step explanation:

(* is multiply)

In order to find the percentage of a value, you multiply the value by the percent. Think of 100% as a scale of 1 to 0.00, since 100% of something has all of it's value, so 50% would be 0.5

23% of 340 is 78.2 ( 340 * 0.23)

Subtract 340 by 78.2, and you get your net pay, 261.8

Another way to do this is subtract 100% by 23%.

so 1 - 0.23= 0.77, which is how much percent of that pay you get to keep

so 340 * 0.77 = 261.8

The vertex of the function is (7, 30)

The axis of symmetry of the function is 7.

The maximum value of the function is 166.

The domain of the function is  {-∞, ∞)

The range of the function is  (-∞, 30] U [30, ∞)

A function is a relationship between inputs where each input is related to exactly one output.

Example:

f(x) = 2x + 1

f(1) = 2 + 1 = 3

f(2) = 2 x 2 + 1 = 4 + 1 = 5

The outputs of the functions are 3 and 5

The inputs of the function are 1 and 2.

We have,

f(x) = -(x - 7)² - 30

f(x) = -(x² - 14x + 49) - 30

f(x) = -x² + 14x - 49 - 30

f(x) = -x² + 14x - 79

The function is in the form of ax² + bx + c

The axis of symmetry is -b/2a.

= -b/2a

= -(14)/(2 x -1)

= 14/2

= 7

The vertex of the function.

= (x, y)

x = -b/21

x = 7

Now,

f(x) = -x² + 14x - 79

y = -49 + 98 - 19

y = -68 + 98

y = 30

Now,    

f'(x) = 0

-2x + 14 = 0

-2x = 14

x = -7

f''(x) = -2 (negative)

f(x) has maximum value at x = -7.

The maximum value.

f(-7) = (-7 - 7)² - 30 = 166

Now,

f(0) = 49 - 30 = -1

f(1) = 36 - 30 = 6

f(2) = 25 - 30 = -5

f(3) = 16 - 30 = -14

f(4) = 9 - 30 = -21

f(5) = 4 - 30 = -26

f(6) = 1 - 30 = -29

f(7) = -30 = -30

f(8) = 1 - 30 = -29

Domain = {-∞, ∞)

Range = (-∞, 30] U [30, ∞)

Thus,

The vertex is (7, 30)

The axis of symmetry is 7.

The maximum value of the function is 166.

The domain and range of the function are  {-∞, ∞) and (-∞, 30] U [30, ∞).
