Answer:

y = -300x

Step-by-step explanation:

The y-intercept passes through 0, in this case, we don't have to include the y intercept to the equation. The slope is -300, or vertical/horizontal (rise/run, the formula for finding slope <<) We just include the slope if there is no y intercept. So, y = -300x is the equation!

The probability that the point chosen is inside the right triangle outlined is approximately 0.3, or 8.33%, rounded to 2 decimal places.

To find the chance that a factor chosen in the ordinary polygon is likewise in the proper triangle mentioned, we need to examine the areas of the two shapes. The location of the everyday polygon may be determined using the formulation:

Area of everyday polygon = (variety of facets × period of 1 side × apothem)/2

The region of the right triangle can be found using the system:

Area of proper triangle = (base × top)/2

The probability is then given by way of the ratio of the 2 areas:

Probability = Area of proper triangle / Area of normal polygon

However, to apply this formulation, we need to recognize some values that aren't given within the query, inclusive of the range of facets, the duration of one facet, the apothem, and the base and peak of the triangle. Without those values, we can't calculate the exact opportunity. We can most effectively estimate it by looking at the discernment and making a few assumptions.

One possible way to estimate the chance is to anticipate that the everyday polygon is a hexagon (has six aspects) and that the right triangle is 1/2 of one among its facets. Then we will approximate the length of one facet as 1 unit and the apothem as 0.866 units (the use of trigonometry). The base and height of the triangle would then be zero. 5 units and 0.866 units respectively.

Using those values, we are able to estimate the areas as follows:

Area of regular polygon ≈ (6 × 1 × 0.866)/2 ≈ 2.598 devices² Area of right triangle ≈ (0.5 × 0.866)/2 ≈ 0.2165 devices²

Probability ≈ 0.2165 / 2.598 ≈ 0.0.33

Therefore, the opportunity is approximately 0.3, or 8.33%, rounded to 2 decimal places.

Note: This is best an estimate primarily based on a few assumptions and approximations. The actual possibility might also vary depending on the actual values of the parameters worried.

All the numbers that show 4% as an equivalent fraction, decimal or percent from the listed options are:

Percent counts the number compared to 100.

So, if we have a%, that means for each 100, there are 'a' parts. If we divide each of them with 100, we get:

For each 1, there are a/100 parts.

Thus, 50% = 50/100 = 0.50 (in decimal)

For this case, the percent we have is 4%

That shows that for each 100 items, we have 4 of them. This can be written in fraction as 4/100

Solving this division, we get the result in decimal as 0.04

Answer:

50%

Step-by-step explanation:

This question is solved by C1V1 + C2V2 ÷ V1 + V2 = final concentration

Let x = volume of 70% solution

let's express the concentrations as decimals, so 70% = 0.7, 50% = 0.5, and 40% = 0.4

then 0.7X + 50L.4 ÷ X + 50L = 0.5

this equation becomes 0.5(X + 50) = 0.7X + 20

which yields 0.5X + 25 = 0.7X +20

combining, we get 5 = 0.2X, and 25 = X

when we mix the two volumes, we get 50L x 40% + 25L x 70%,

which yields 20L of 100% alcohol, and 17.5L of 100% alcohol, for a total of 37.5L of alcohol in 75L of solution

which is a final concentration of 50%

There are 25 liters volume of 70% alcohol solution used.

What is mean by Percentage?

A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.

Let volume of 70% alcohol solution = x

So, By given information, we can formulate;

⇒ 70% × x + 40% × 50 / (x + 50) = 50%

⇒ 0.7x + 20 = 0.5 (x + 50)

⇒ 0.7x + 20 = 0.5x + 25

⇒ 0.2x = 5

⇒ x = 25

Directional derivative of the function g(s, t) = st at the point (3, 9) in the direction of the vector v = 2i - j is 15/√5.

Here are the steps:

1. Compute the partial derivatives of g(s, t) with respect to s and t:
  ∂g/∂s = t
  ∂g/∂t = s

2. Evaluate the partial derivatives at the given point (3, 9):
  ∂g/∂s(3, 9) = 9
  ∂g/∂t(3, 9) = 3

3. Write the gradient vector ∇g as a combination of the partial derivatives:
  ∇g = 9i + 3j

4. Normalize the given direction vector v = 2i - j:
  ||v|| = √(2² + (-1)²) = √5
  v_normalized = (2/√5)i + (-1/√5)j

5. Compute the directional derivative D_v g by taking the dot product of ∇g and v_normalized:
  D_v g = (9i + 3j) • ((2/√5)i + (-1/√5)j)
         = (9 ×  (2/√5)) + (3 × (-1/√5))
         = (18/√5) + (-3/√5)

Step-by-step explanation:

The polynomial with zeros of −3, −1, and 2, and passes through the point (3,11) is:

P(x) = (11/24)*(x + 3)*(x + 1)*(x - 2)

We know that the zeros are −3, −1, and 2, so if we define the leading coefficient as A, the polynomial can be written as:

p(x) = A*(x + 3)*(x  + 1)*(x - 2)

Now we want this to pass through the point (3, 11), then we get:

p(3) = 11 = A*(3 + 3)*(3 + 1)*(3 - 2)

         11 = A*6*4*1

         11 = A*24

The correct answer is k+3 ke-2.

To determine which formula is not equivalent to the other two, we can compare each formula step-by-step. Let's analyze each formula:

1. (-1k-3 k +3 k+ 4 ks4
2. k+3 ke-2
3. k-3 ks4

Starting with formula 1, we can see that it consists of three terms: -1k-3, k+3, and k+4ks4. Each term is separated by a space.

Moving on to formula 2, we have k+3ke-2. This formula also consists of three terms: k+3, k, and e-2. In this case, we have a variable (k) combined with two different exponents (3 and -2).

Finally, formula 3 is k-3ks4. It consists of two terms: k-3 and ks4. Again, each term is separated by a space.

Comparing the three formulas, we can see that formula 1 has three terms, while formulas 2 and 3 have two terms each. Additionally, formula 1 includes the term k+4ks4, which is not present in formulas 2 and 3.

The total length of the curve is:

L = L₁ + L₂ + L₃ = 2.841 + 2 + 4 = 8.841.

What is the linear function?

A linear function is defined as a function that has either one or two variables without exponents. It is a function that graphs to a straight line.

To find the length of the curve, we need to break it into its three segments and find the length of each segment separately.

Segment 1: y = x² from (0,0) to (2,4)

The length of this segment can be found using the arc length formula for a curve y = f(x) from x = a to x = b:

L = ∫[a,b] √[1 + (dy/dx)²] dx

In this case, f(x) = x², so dy/dx = 2x. Thus, the length of this segment is:

L1 = ∫[0,2] √[1 + (2x)²] dx ≈ 2.841

Segment 2: Straight line from (2,4) to (0,4)

The length of this segment is simply the distance between the two points:

L₂ = √[(0-2)² + (4-4)²] = 2

Segment 3: y-axis from (0,4) to (0,0)

The length of this segment is simply the distance between the two points:

L3 = √[(0-0)² + (4-0)²] = 4

Therefore, the total length of the curve is:

L = L₁ + L₂ + L₃ = 2.841 + 2 + 4 = 8.841

After pouring some water from container A into container B, the new height of the water in both containers will be equal.

When container A is filled with water to the brim, it reaches its maximum capacity. Let's assume the initial height of the water in container A is h.

When some water is poured from container A into container B, the water level in both containers will gradually equalize until they reach the same height. Let's denote this new height as H.

The reason the water levels equalize is due to the principle of fluid equilibrium. When the containers are connected and the water is allowed to flow, the water seeks a common level. This occurs because the pressure at the same height in a fluid is equal.

Therefore, after pouring water from container A to container B, the final height of the water in both containers will be H, which indicates that the water has reached an equilibrium point where the pressure is equal in both containers.
