The system of inequalities on the graph is:

y ≤ 2

y > 2x - 4

Here we have the graph of a system of inequalites.

First, we can see a solid horizontal line, such that the shaded region is below that line, then one of the two inequalities will be:

y ≤ 2

And then we have a dashed line with a slope of 2 and an y-intercept of -4, this time the region above the line is shaded.

y > 2x - 4

Then the system of inequalities on the graph is:

The pH of Cu(OH) is usually low (around 5.50) due to the formation of Cu(OH)2, which acts as a weak acid.

The low pH of Cu(OH) is primarily attributed to the formation of Cu(OH)2. When Cu(OH) reacts with water, it forms Cu(OH)2 and releases a hydrogen ion (H+), which increases the concentration of H+ ions in the solution and lowers the pH. Cu(OH)2 acts as a weak acid, contributing to the acidity of the solution. The low pH indicates that the solution is acidic.

Regarding part 4, the inaccuracy in determining the pH values of Cu(OH)2, Ba(OH)2, and Mg(OH)2 may be attributed to procedural errors. It could include issues such as improper calibration of pH meters, contamination of the solutions, or insufficient mixing of the substances. These errors can lead to inaccurate pH measurements and affect the reliability of the results.

If metal nitrates were used instead of metal chlorides in part 2, the results might not be the same. Nitrates can influence the acidity or basicity of the solution differently compared to chlorides. The specific chemical properties of the metal nitrates and their respective hydroxides would determine the resulting pH. Therefore, it is possible that using metal nitrates could yield different pH values compared to using metal chlorides. The exact outcome would depend on the specific characteristics of the metal nitrates and their interactions with water.

The solution to the inequality 4/5p + 9 ≥ 6 is:

p ≥ -15/4.

An inequality is solved similarly to an equality, as the desired variable to find the result is isolated.

The difference, compared to an equality, is that instead of a single value, the solution of an inequality is composed by a range of infinity values in the interval of the solution.

In this problem, the inequality is given as follows:

4/5p + 9 ≥ 6

Then the term with p is isolated as follows:

4/5p ≥ -3

Answer:

To find out how many 2/5 meter pieces Sven can cut off from a board that is 9/10 meters long, we need to divide the length of the board by the length of each piece.

We can convert the mixed number 2/5 to an improper fraction by multiplying the whole number 1 by the denominator 5 and adding the numerator 2, giving us 7/5.

Then, we can divide the length of the board, which is 9/10 meters, by the length of each piece, which is 7/5 meters:

(9/10) ÷ (7/5)

To divide by a fraction, we can multiply by its reciprocal:

(9/10) x (5/7)

Simplifying the fractions:

(9 x 5) / (10 x 7) = 45 / 70

We can simplify this fraction by dividing both the numerator and denominator by their greatest common factor, which is 5:

(45/5) / (70/5) = 9/14

Therefore, Sven can cut off 9 pieces that are 2/5 meters long from a board that is 9/10 meters long.

Step-by-step explanation:

the simple answer is that Sven can cut off 9 pieces that are 2/5 meters long from a board that is 9/10 meters long.

The calculated equation that represents a line parallel to y = -2x + 4 is (c) -2x - y = 3.

The equation of a line that is parallel to y = -2x + 4 will have the same slope as -2 since parallel lines have the same slope.

Therefore, we need to look for an equation that has a slope of -2.

(a) 1/2x + y = 1 has a slope of -1/2, which is not equal to -2. Thus, it is not parallel to y = -2x + 4.

(b) -2x + y = 8 has a slope of 2, which is not equal to -2. Thus, it is not parallel to y = -2x + 4.

(c) -2x - y = 3 can be rearranged to y = -2x - 3, which has a slope of -2, so it is parallel to y = -2x + 4.

(d) -1/2x + y = 5 has a slope of 1/2, which is not equal to -2. Thus, it is not parallel to y = -2x + 4.

Therefore, the equation that represents a line parallel to y = -2x + 4 is (c) -2x - y = 3.

The circumference of the circle is given by C = 2 * π * r, where r is the radius. In this case, the circumference of the circle is 2 * π * 14 = 88 cm.

Let's call the linear speed of the object v. Then, in 20 seconds, the object travels a distance of v * 20. This distance is equal to the arc length of the central angle of 1/2 radian:

v * 20 = (1/2) * (C/2π) = (1/2) * (88/2π) = 22/π cm

Solving for v, we get:

v = (22/π) / 20 = 22 / (20π) cm/s

The angular speed ω can be found by dividing the central angle by the time it took to travel that angle:

ω = 1/2 / 20 = 1/40 rad/s

So the linear speed of the object is v = 22 / (20π) cm/s, and the angular speed is ω = 1/40 rad/s.

The velocity of the boat when it reaches the buoy is approximately 17.32 m/s. This is found using the equation v² = u² + 2as, where u is the initial velocity, a is the acceleration, and s is the displacement.

To solve this problem, we can use the equations of motion. The initial velocity of the boat, u, is 30 m/s, the acceleration, a, is -3.0 m/s² (negative because the boat is slowing down), and the displacement, s, is 100 m. We need to find the final velocity, v, when the boat reaches the buoy.

We can use the equation: v² = u² + 2as

Substituting the given values, we have:

v² = (30 m/s)² + 2(-3.0 m/s²)(100 m)

v² = 900 m²/s² - 600 m²/s²

v² = 300 m²/s²

Taking the square root of both sides, we find:

v = √300 m/s

v ≈ 17.32 m/s

Therefore, the velocity of the boat when it reaches the buoy is approximately 17.32 m/s.

The problem provides the initial velocity, acceleration, and displacement of the boat. By applying the equation v² = u² + 2as, we can find the final velocity of the boat. This equation is derived from the kinematic equations of motion. The equation relates the initial velocity (u), final velocity (v), acceleration (a), and displacement (s) of an object moving with uniform acceleration.

In this case, the boat is decelerating with a constant acceleration of -3.0 m/s². By substituting the given values into the equation and solving for v, we find that the velocity of the boat when it reaches the buoy is approximately 17.32 m/s.

Glucose transport across a membrane is an example of passive transport, while cholesterol transport across a membrane is an example of facilitated diffusion. The other phrases do not fit into either category.

Passive transport is a process by which substances move across a cell membrane without the use of energy. Glucose transport across a membrane is an example of passive transport because it occurs down its concentration gradient, from an area of higher concentration to an area of lower concentration.

Facilitated diffusion is a type of passive transport that involves the use of transport proteins to move specific substances across a membrane. Cholesterol transport across a membrane is an example of facilitated diffusion because it requires protein-assisted movement.

Based on the given options, the classification of each phrase is as follows:

- Passive transport: Glucose transport across a membrane
- Facilitated diffusion: Cholesterol transport across a membrane protein-assisted movement
- Both processes: None
- Neither: movement to an area of lower concentration, movement across a membrane, requires an input of energy

To summarize, While cholesterol transport through a membrane is an example of assisted diffusion, glucose transfer across a membrane is an example of passive transport. The remaining utterances don't fall into either group.
