Answer: Gradient = -3

Step-by-step explanation:

According to the figure, we compose the equation of a straight line:

(0;6)     ((2;0)      y=bx+k    b=?

                      Equation of a straight line

                              \(\displaystyle\\\boxed {\frac{x-x_1}{x_2-x_1} =\frac{y-y_1}{y_2-y_1} }\)

\(\displaystyle\\\frac{x-0}{2-0}=\frac{y-6}{0-6} \\\frac{x}{2}=\frac{y-6}{-6} \\\)

Multiply both sides of the equation by -6:

\(-3x=y-6\\-3x+6=y\\y=-3x+6.\\So, \\Gradient\ \phi(x)=\frac{\partial y}{\partial x} \\\phi(x)=(-3x+6)'\\\phi(x)=-3.\)

Required positive solution of the given quadratic equation is 9.

Step-by-step explanation:

Given Equation,

x² - 36 = 5x

We need to find positive solution of the given equation.

We solve the given quadratic equation using middle term split method.

x² - 36 = 5x

x² - 5x - 36 = 0

x² - 9x + 4x - 36 = 0

x( x - 9 ) + 4( x - 9 ) = 0

( x - 9 )( x + 4 ) = 0

x - 9 = 0 and x + 4 = 0

x = 9 and x = -4

Therefore, Required positive solution of the given quadratic equation is 9.

Obtuse; 25° + 87° = 112° and 112° is an obtuse angle is the correct answer.

Triangle is a three-sided polygon with three angles. All the sides of a triangle are connected, forming a closed shape. Triangles come in many different shapes and sizes. The most common type of triangle is an equilateral triangle, which has three equal sides and three equal angles. Other types of triangles include isosceles, scalene, obtuse, and right triangles. Triangles are used in many different fields, including architecture, engineering, and mathematics.

The triangle is obtuse because 25° + 87° = 112° and 112° is an obtuse angle. An obtuse triangle is one in which one angle has a measure greater than 90°.

The remaining two angles are acute, meaning they measure less than 90°.

If r is < 0, then lambda must be:  Less than 0, Less than 1, Greater than 1  and Greater than 0. The correct answers are: A), B), C), and D).

Recall that the exponential growth or decay model is given by the function:

\(y = y0 * e^(rt)\)

where y0 is the initial value of the function, r is the rate of change (growth or decay), t is the time, and e is the mathematical constant approximately equal to 2.71828.

If r < 0, then the function represents exponential decay, and we have:

\(y = y0 * e^(rt)\)

y/y0 = e^(rt)

Taking the natural logarithm of both sides, we get:

ln(y/y0) = rt

r = (1/t) * ln(y/y0)

Since ln(y/y0) is the natural logarithm of a ratio, it can take any real value. Therefore, r can take any negative value, and there is no restriction on the value of lambda (which is\(e^r\)).

Let's consider an example with hypothetical data for two crops, Wheat and Rice, obtained from five farmers:

| Farmer | Rabi Crop (tons/ha) | Kharif Crop (tons/ha) |

|--------|--------------------|----------------------|

|   F1   |        4.5         |         6.2          |

|   F2   |        3.8         |         5.5          |

|   F3   |        4.2         |         6.0          |

|   F4   |        5.1         |         7.3          |

|   F5   |        4.9         |         6.5          |

```

To calculate the selling price and profit, you would need additional information such as the selling price per ton for each crop and the cost of production. Let's assume the selling price for Wheat is $200 per ton and for Rice is $250 per ton. We will also assume a production cost of $150 per ton for both crops.

To calculate the profit for each farmer, you can use the following formula:

Profit = (Selling Price - Production Cost) * Production

For example, let's calculate the profit for Farmer F1 with the given data:

Profit for Wheat = (200 - 150) * 4.5 = $225

Profit for Rice = (250 - 150) * 6.2 = $620

Repeat this calculation for each farmer and crop combination to obtain the profits for all.

Once you have the data for production, selling price, and profit, you can create a double bar graph to compare the production of Wheat and Rice in the farmers' fields. The x-axis will represent the farmers, and the y-axis will represent the production (tons/ha). Each farmer will have two bars, one for Wheat and one for Rice, showing the respective production amounts.

Please note that the actual selling price, production costs, and profits may vary based on various factors, and you would need specific data and current market information to calculate accurate values.

The equation in spherical coordinates is ρ = 5. This equation represents a sphere centered at the origin with a radius of 5 units in the ρ direction.

To write the equation \(x^2 + y^2 + z^2 = 25\) in spherical coordinates, we need to express x, y, and z in terms of the spherical coordinates (ρ, θ, φ).

In spherical coordinates, ρ represents the distance from the origin to the point, θ represents the azimuthal angle measured from the positive x-axis in the xy-plane, and φ represents the polar angle measured from the positive z-axis.

To transform the Cartesian coordinates (x, y, z) to spherical coordinates, we can use the following equations:

x = ρ sin(φ) cos(θ)

y = ρ sin(φ) sin(θ)

z = ρ cos(φ)

Now let's substitute these equations into the given equation:

\((x^2) + (y^2) + (z^2) = 25\)

(ρ sin(φ) cos(θ))² + (ρ sin(φ) sin(θ))² + (ρ cos(φ))² = 25

ρ² (sin²(φ) cos²(θ) + sin²(φ) sin²(θ) + cos²(φ)) = 25

ρ² (sin²(φ) (cos²(θ) + sin²(θ)) + cos²(φ)) = 25

ρ²(sin²(φ) + cos²(φ)) = 25

ρ²= 25

This simplifies to:

ρ = 5

Therefore, the equation in spherical coordinates is ρ = 5. This equation represents a sphere centered at the origin with a radius of 5 units in the ρ direction.

In spherical coordinates, the equation ρ = 5 describes all points that are at a distance of 5 units from the origin, regardless of the values of θ and φ.

The given expression is\((21 - 7x) / (x + 3) / (x^2 - 3x) / (2x + 3)\). To simplify the expression, we need to apply the rules of fraction division and simplify each fraction individually.

To simplify the given expression, we start by dividing the fractions. Division of fractions is performed by multiplying the first fraction by the reciprocal of the second fraction.

The expression can be rewritten as\((21 - 7x) / (x + 3) * (2x + 3) / (x^2 - 3x).\)Next, we can simplify each fraction separately.

In the numerator, we can multiply out the terms: \((21 - 7x) * (2x + 3) = 42x + 63 - 14x^2 - 21x.\)

In the denominator, we can factor out an \(x: x^2 - 3x = x(x - 3).\)

Putting it all together, the simplified expression becomes \((42x + 63 - 14x^2 - 21x) / [(x + 3) * x(x - 3)].\\\)

Further simplification may be possible depending on specific factors and terms present in the expression, but without additional information or specific values for x, we cannot simplify the expression any further.

topsoil cost per foot is $5

And we have to find the cost which required to put a 0. 5 ft layer of topsoil on the entire garden.

So,

The  side length of the square garden is 10ft.

Now, the volume of the cube is (a)^2

And

Total volume of cube = 10*10

Total volume of cube = 100 per square foot.

Now, we find the cost required for a topsoil.

Cost required to put a topsoil of 1 foot in the total volume of cube = volume*cost

So,

Cost required to put a topsoil of 1 foot in the total volume of cube = 1000*5

Cost required to put a topsoil of 1 foot in the total volume of cube = $5000

if we put a topsoil of 0.5 feet then

The cost required = $5000/0.5

The cost required = $1000.

The most accurate way to describe a vector field F on R3 is (c) a function F from R3 to R3

A vector field is best described as a function F from R3 to R3. In other words, at each point (x, y, z) in 3D space, the vector field assigns a vector (F1(x, y, z), F2(x, y, z), F3(x, y, z)). The vector field can be visualized by drawing arrows or streamlines to represent the direction and magnitude of the vector at each point in space. A vector field assigns a vector to each point in space, so it requires a function that maps from R3 (a point in space) to another vector in R3.

The vector field is useful in physics, engineering, and mathematics for modeling various physical phenomena, such as fluid flow, electromagnetic fields, and gravitational fields.

Answer:

the each T-shirt and each pair of pants cost is $20 and $12 respectively

Step-by-step explanation:

The computation of the each T-shirt and each pair of pant cost is shown below:

Let us assume each T-shirt be x

And, the each pair of pant be y

Now the equations are

8x + 5y = $220

5x + y = $112

It could be write as

y = $112 - 5x

Now put the value of y in equation 1

8x + 5($112 - 5x) = $220

8x + $560 - $25x = $220

-17x = -$340

x = 20
