The polynomial that represents the product of 2X-4 and X² +6X -2 is 2X³ + 8X³ - 24X + 8.

To find the product of the two polynomials, we can use the distributive property of multiplication over addition, which states that:

(a + b)c = ac + bc

Using this property, we can distribute the terms of the first polynomial, 2X-4, to each term of the second polynomial, X² +6X -2, and then simplify the resulting expression:

(2X - 4) × (X² + 6X - 2)

= 2X × X² + 2X × 6X + 2X × (-2) - 4 × X² - 4 × 6X + 4 × 2

= 2X³ + 12X² - 4X² - 24X + 8

= 2X³ + 8X² - 24X + 8

Therefore, the polynomial that represents the product of 2X-4 and X² +6X -2 is 2X³ + 8X³ - 24X + 8.

The second step when evaluating the given expression is to subtract 6 from 18, simplifying the expression within the parentheses to 12.

The second step when evaluating the expression 3 + (18 - 6) + 20 + 4 is to perform the operation within the parentheses, specifically the subtraction inside the parentheses.

Let's break down the expression step by step:

1. Start with the expression: 3 + (18 - 6) + 20 + 4

2. The expression inside the parentheses is 18 - 6. To simplify this, we subtract 6 from 18, which equals 12.

3. Now, we rewrite the expression with the simplified part: 3 + 12 + 20 + 4

4. At this point, the expression consists of addition operations only. When evaluating an expression with multiple addition operations, we start from the left and work our way to the right, performing the addition operation between two numbers at a time.

5. The first addition operation is between 3 and 12. Adding these two numbers gives us 15.

6. We rewrite the expression again, replacing the addition of 3 and 12 with the result: 15 + 20 + 4

7. Now, we perform the next addition operation between 15 and 20, resulting in 35.

8. We rewrite the expression once more: 35 + 4

9. Finally, we perform the last addition operation between 35 and 4, resulting in 39.

Therefore, the second step when evaluating the given expression is to subtract 6 from 18, simplifying the expression within the parentheses to 12.

Josh should mix 1.2 gallons of dark pink paint and 1.8 gallons of light pink paint to achieve the desired medium pink color.

To find out how much of each leftover paint Josh should mix to achieve a medium pink color (50% red), we can set up a system of equations based on the percentages of red in the paints.

Let's assume that Josh needs x gallons of dark pink paint and y gallons of light pink paint to achieve the desired color.

The total amount of paint needed is 3 gallons, so we have the equation:

x + y = 3

The percentage of red in the dark pink paint is 80%, which means 80% of x gallons is red. Similarly, the percentage of red in the light pink paint is 30%, which means 30% of y gallons is red. Since Josh wants a 50% red mixture, we have the equation:

(80/100)x + (30/100)y = (50/100)(x + y)

Simplifying this equation, we get:

0.8x + 0.3y = 0.5(x + y)

Now, we can solve this system of equations to find the values of x and y.

Let's multiply both sides of the first equation by 0.3 to eliminate decimals:

0.3x + 0.3y = 0.3(3)

0.3x + 0.3y = 0.9

Now we can subtract the second equation from this equation:

(0.3x + 0.3y) - (0.8x + 0.3y) = 0.9 - 0.5(x + y)

-0.5x = 0.9 - 0.5x - 0.5y

Simplifying further, we have:

-0.5x = 0.9 - 0.5x - 0.5y

Now, rearrange the equation to isolate y:

0.5x - 0.5y = 0.9 - 0.5x

Next, divide through by -0.5:

x - y = -1.8 + x

Canceling out the x terms, we get:

-y = -1.8

Finally, solve for y:

y = 1.8

Substitute this value of y back into the first equation to solve for x:

x + 1.8 = 3

x = 3 - 1.8

x = 1.2

Therefore, Josh should mix 1.2 gallons of dark pink paint and 1.8 gallons of light pink paint to achieve the desired medium pink color.

2) Find the discriminant D.

 If  D > 0, then the quadratic equation has two distinct real roots.

  If  D= 0, then the quadratic equation has two identical real roots.

  If  D < 0, then the quadratic equation has no real roots.

  D = b² - 4ac

 x² - 6x + 9 = 0

a = 1  ; b = -6 ; c = 9

The median of a line plot The median is the central value in a data set that is arranged in numerical order from least to greatest. In other words, the median is the middle number of a set of data. To find the median of a set of data on a line plot, follow the steps below:

Step 1: Arrange the data in numerical order from least to greatest. In the line plot provided above, the data is already arranged in order from least to greatest. It ranges from 4 to 12.

Step 2: Determine the total number of data points. In this case, there are 8 data points.

Step 3: Identify the middle value in the data set. This is done by dividing the total number of data points by 2 (the middle point). If the number of data points is even, the median is the average of the two middle values. If the number of data points is odd, the median is the middle value itself. Since there are 8 data points in the line plot above, we have an even number of data points. The two middle values are 6 and 7, so the median is the average of these two values.

Step 4: Calculate the median. Add the two middle values (6 and 7) together and divide by 2:6 + 7 = 13 13/2 = 6.5

Therefore, the median of the data shown on the line plot is 6.5.

Therefore, we need to add approximately 0.0526 gallons of water (which is equivalent to about 6.63 fluid ounces) to 1 gallon of pure antifreeze to obtain a solution that is 95% antifreeze.

In mathematics, an equation is a statement that asserts the equality of two expressions. An equation typically consists of one or more variables, coefficients, and constants, and it can include mathematical operations such as addition, subtraction, multiplication, and division. The expressions on both sides of the equation are separated by an equal sign, indicating that they have the same value. The goal of solving an equation is to determine the value of the variables that make the equation true. Equations are used in many areas of mathematics and science to model real-world phenomena and solve problems.

Here,

Let's assume that we need to add x gallons of water to 1 gallon of pure antifreeze to obtain a solution that is 95% antifreeze. We know that the final solution will contain 1 gallon of antifreeze, and that this will be 95% of the total solution (the remaining 5% will be water). So, we can write:

1 gallon of antifreeze = 95% of (1 gallon of antifreeze + x gallons of water)

We can simplify this equation by converting 95% to a decimal:

0.95 × (1 gallon of antifreeze + x gallons of water) = 1 gallon of antifreeze

Now we can solve for x by isolating it on one side of the equation. First, let's distribute the 0.95:

0.95 gallons of antifreeze + 0.95x gallons of water = 1 gallon of antifreeze

Next, let's isolate x by subtracting 0.95 gallons of antifreeze from both sides:

0.95x gallons of water = 0.05 gallons of antifreeze

Finally, we can solve for x by dividing both sides by 0.95:

x = 0.05 gallons of antifreeze ÷ 0.95

x ≈ 0.0526 gallons of water

Let's assume the width of the swimming pool is "x" meters.

The length of the swimming pool would then be "x + 12" meters.

Considering the walkway surrounds the pool on all sides, the total width including the walkway would be "x + 2 + 2" meters (two sides of the walkway).

The total length, including the walkway, would be "x + 12 + 2 + 2" meters.

The area of the walkway is given as 168 square meters, which can be represented as:

Area of the walkway = Total area including the walkway - Area of the pool

168 = (x + 2 + 2) * (x + 12 + 2 + 2) - x * (x + 12)

168 = (x + 4) * (x + 16) - x^2 - 12x

168 = x^2 + 16x + 4x + 64 - x^2 - 12x

168 = 8x + 64

8x = 168 - 64

8x = 104

x = 104/8

x = 13

Therefore, the width of the swimming pool is 13 meters, and the length of the swimming pool is 13 + 12 = 25 meters.

Answer: The Jacobian of the transformation is: J = 8v(4w)3u - 8u(4v)3w = 24uvw

Step-by-step explanation:

To determine the Jacobian of the transformation, we first need to get the partial derivatives of x, y, and z with respect to u, v, and w:

∂x/∂u = 8v

∂x/∂v = 8u

∂x/∂w = 0∂y/∂u = 0

∂y/∂v = 4w

∂y/∂w = 4v∂z/∂u = 3w

∂z/∂v = 0

∂z/∂w = 3u

The Jacobian matrix J is then:

| ∂x/∂u ∂x/∂v ∂x/∂w |

| ∂y/∂u ∂y/∂v ∂y/∂w |

| ∂z/∂u ∂z/∂v ∂z/∂w |

Substituting in the partial derivatives we found above, we get:

| 8v 8u 0 |

| 0 4w 4v |

| 3w 0 3u |

So, the Jacobian of the transformation is:J = 8v(4w)3u - 8u(4v)3w = 24uvw

x² + y² = 5² = 25

(12/y)² + y² = 25

144/y² + y² = 25    multiply by y² on both sides

144 + y⁴ = 25y²      rewrite the equation

y⁴ -25y² + 144 = 0

rewrite with z=y²  and  z²=y⁴

z² - 25z + 144 = 0    now you can use the quadratic formula to find the roots of z (a=1, b=-25, c=144).  Consider only the positive roots of z:

z = 16, 9
