Answer:

b = sp

Step-by-step explanation:

box = seeds per packet

The given relation can be used to find the total number of seeds in box b, using the equation b = sp. Hence, 3rd option is the right choice.

Equations are relations shown between two equal algebraic expressions.

We are given a box of sunflower seeds, containing p packets of seeds, each of which contains s number of seeds.

We are asked to write an equation that can be used to find the total number of seeds in the box, b.

We know that the box contains p packets of seeds.

In 1 packet we have s number of seeds.

∴ In p packets, we will have an s*p number of seeds or sp seeds.

Since the box contains p packets and the total number of seeds in the box is b, then we can say that

b = the number of seeds in p packets

or, b = sp, which is the required equation.

∴ The given relation can be used to find the total number of seeds in box b, using the equation b = sp. Hence, 3rd option is the right choice.

Comparing the values of δz and dz, we have:

δz - dz = 8.9957 - (-0.75) ≈ 9.7457

Since δz - dz is positive, we can conclude that δz is greater than dz.

To compare the values of δz and dz, we can use the partial derivative of z with respect to x and y, and the given change in x and y:

∂z/∂x = 2x - y

∂z/∂y = -x - 14y^2

At the point (1, -1), we have:

∂z/∂x = 2(1) - (-1) = 3

∂z/∂y = -(1) - 14(-1)^2 = -15

Using the formula for total differential:

dz = (∂z/∂x)dx + (∂z/∂y)dy

Substituting the given change in x and y, we get:

dz = (3)(-0.04) + (-15)(0.05) = -0.75

Therefore, dz = -0.75.

To find δz, we can use the formula:

δz = z(0.96, -0.95) - z(1, -1)

Substituting the given points into the function z, we get:

z(0.96, -0.95) = (0.96)^2 - (0.96)(-0.95) - 7(-0.95)^2 ≈ 1.9957

z(1, -1) = 1^2 - 1(-1) - 7(-1)^2 = -7

Substituting these values into the formula, we get:

δz = 1.9957 - (-7) = 8.9957

Therefore, δz = 8.9957.

Comparing the values of δz and dz, we have:

δz - dz = 8.9957 - (-0.75) ≈ 9.7457

Since δz - dz is positive, we can conclude that δz is greater than dz.

The partial derivative diffusivity equation for spherical flow is ∂²p/∂r² + (1/r) ∂p/∂r = ϕμC/k ∂p/∂t, and for hemispherical flow, it is the same equation.

1. The partial derivative diffusivity equation for spherical flow is derived from the spherical coordinate system and applies to radial flow in a spherical geometry. It can be expressed as ∂²p/∂r² + (1/r) ∂p/∂r = ϕμC/k ∂p/∂t.

2. The partial derivative diffusivity equation for hemispherical flow is derived from the hemispherical coordinate system and applies to radial flow in a hemispherical geometry. It can be expressed as ∂²p/∂r² + (1/r) ∂p/∂r = ϕμC/k ∂p/∂t.

1. For the derivation of the partial derivative diffusivity equation for spherical flow, we consider a spherical coordinate system with the radial direction (r), the azimuthal angle (θ), and the polar angle (φ). By assuming steady-state flow and neglecting the other coordinate directions, we focus on radial flow. Applying the Laplace operator (∇²) in spherical coordinates, we obtain ∇²p = (1/r²) (∂/∂r) (r² ∂p/∂r). Simplifying this expression, we arrive at ∂²p/∂r² + (1/r) ∂p/∂r.

2. Similarly, for the derivation of the partial derivative diffusivity equation for hemispherical flow, we consider a hemispherical coordinate system with the radial direction (r), the azimuthal angle (θ), and the elevation angle (ε). Again, assuming steady-state flow and neglecting the other coordinate directions, we focus on radial flow. Applying the Laplace operator (∇²) in hemispherical coordinates, we obtain ∇²p = (1/r²) (∂/∂r) (r² ∂p/∂r). Simplifying this expression, we arrive at ∂²p/∂r² + (1/r) ∂p/∂r.

In both cases, the term ϕμC/k ∂p/∂t represents the source or sink term, where ϕ is the porosity, μ is the fluid viscosity, C is the compressibility, k is the permeability, and ∂p/∂t is the change in pressure over time.

These equations are commonly used in fluid mechanics and petroleum engineering to describe radial flow behavior in spherical and hemispherical geometries, respectively.

Answer: I think 9

Step-by-step explanation:

The minimum horizontal length of the ramp (in feet) is approximately 17.61 feet.

We can start by visualizing the situation: the wheelchair ramp rises 30 inches vertically and we need to find its horizontal length. The angle of elevation is the angle between the ramp and the ground, and we know that it must not exceed 8°.

Let's call the horizontal length of the ramp "x". Then we can use trigonometry to find the vertical height of the ramp:

tan(8°) = 30 inches / x

Multiplying both sides by x, we get:

x × tan(8°) = 30 inches

Dividing both sides by tan(8°), we get:

x = 30 inches / tan(8°)

We can now use a calculator to determine an approximation of the value of x:

x ≈ 211.37 inches

However, the question asks for the minimum horizontal length of the ramp in feet. We can divide inches by 12 to get feet:

x ≈ 17.61 feet

Therefore, the minimum horizontal length of the ramp (in feet) is approximately 17.61 feet.

The derivative and domain of the function f(x) = x²-2x³  is :\((-\infty, \infty)\).

The slope of a function's graph or, more precisely, the slope of the tangent line at a point can be used to interpret a function's derivative.

Its computation actually stems from the slope formula for a straight line, with the exception that curves require the employment of a limiting procedure.

Calculation for the derivative:

Step 1: Use the definition of the derivative. Remember that f(x+h) means plug (x+h) into everywhere there is an "x" in f(x).

\(\begin{aligned}f^{\prime}(x) &=\lim _{h \rightarrow 0} \frac{f(x+h)-f(x)}{h} \\&=\lim _{h \rightarrow 0} \frac{(x+h)^{2}-2(x+h)^{3}-\left(x^{2}-2 x^{3}\right)}{h} \\&=\lim _{h \rightarrow 0} \frac{\left(x^{2}+2 h x+h^{2}\right)-2(x+h)(x+h)^{2}-x^{2}+2 x^{3}}{h} \quad \text { cancel } x^{2}\end{aligned}\)

       \(\begin{aligned}&=\lim _{h \rightarrow 0} \frac{\left(2 h x+h^{2}\right)-2(x+h)\left(x^{2}+2 h x+h^{2}\right)+2 x^{3}}{h} \\&=\lim _{h \rightarrow 0} \frac{\left(2 h x+h^{2}\right)-2\left(x^{3}+2 h x^{2}+h^{2} x+h x^{2}+2 h^{2} x+h^{3}\right)+2 x^{3}}{h} \\&=\lim _{h \rightarrow 0} \frac{2 h x+h^{2}-2 x^{3}-4 h x^{2}-2 h^{2} x-2 h x^{2}-4 h^{2} x-2 h^{3}+2 x^{3}}{h}\end{aligned}\)

       \(=\lim _{h \rightarrow 0} \frac{2 h x+h^{2}-6 h x^{2}-6 h^{2} x-2 h^{3}}{h}\)

Step 2: Cancel out a factor of h from each term in the numerator with the h in the denominator. Then direct substitute h=0.

      \(\begin{aligned}&=\lim _{h \rightarrow 0}\left(2 x+h-6 x^{2}-6 h x-2 h^{2}\right) \\&=2 x+0-6 x^{2}-6(0) x-2(0)^{2} \\&=2 x-6 x^{2}\end{aligned}\)

f and f' are polynomials, so their domains are all real numbers.

Therefore,  for f(x) = x²-2x³      domain of f and f' :\((-\infty, \infty)\).

Answer:

Step-by-step explanation:

First, find the probability of pulling out a big marble.

Since there are 7 big marbles, and 26 in total, the probability is 7/26

Now, find the probability of pulling out a small marble after the replacement.

There are 6 small marbles and 26 in total, so the probability is 6/26. This can be simplified by dividing each side by 2. This will get you 3/13

To find the probability of both of these happening, multiply the probabilities by each other:

(7/26) x (3/13)

= 7/26

So, the probability is 7/26

Answer: The nonprofit can provide 5,500 gallons of water per day. To calculate the gallons per day per person for a village with a population of 850, we divide the total amount of water by the population: 5,500 gallons / 850 people = approximately 6.47 gallons per day per person

Step-by-step explanation:

The 0.5 gallons of water per day accessible in some areas of the world is significantly lower than the 6.47 gallons per day per person calculated in question one. This highlights the disparity in water availability and access between different regions and communities.

The average American uses 80-100 gallons of water per day, which is considerably higher than the 6.47 gallons per day per person available in the village. This reflects the higher water consumption patterns in developed countries and emphasizes the need for efficient water management and conservation.

If we only had the calculated amount of water (6.47 gallons per day per person) to use each day, it would be crucial to prioritize essential needs such as drinking, cooking, and personal hygiene. Conservation measures would be necessary to ensure the limited water supply is used efficiently and sustainably. Non-essential uses like watering lawns or washing vehicles would need to be minimized or eliminated to meet the basic needs of the community.

One serving (56 grams) of hard salted pretzels contains approximately 234 calories.

To estimate the number of calories in one serving of hard salted pretzels, we need to consider the amount of fat, carbohydrates, and protein in the pretzels.

First, let's calculate the calories from fat. We know that one gram of fat releases 9 calories. The pretzels contain 2 grams of fat, so we multiply 2 by 9 to get 18 calories from fat.

Next, let's calculate the calories from carbohydrates. One gram of carbohydrate typically releases about 4 calories. The pretzels contain 48 grams of carbohydrates, so we multiply 48 by 4 to get 192 calories from carbohydrates.

Now, let's calculate the calories from protein. Like carbohydrates, one gram of protein typically releases about 4 calories. The pretzels contain 6 grams of protein, so we multiply 6 by 4 to get 24 calories from protein.

To estimate the total number of calories in one serving of hard salted pretzels, we add up the calories from fat, carbohydrates, and protein:

18 calories from fat + 192 calories from carbohydrates + 24 calories from protein = 234 calories.

Therefore, one serving (56 grams) of hard salted pretzels contains approximately 234 calories.
