Let's call the number of players on Team A as "A" and the number of players on Team B as "B".

We know that 1/5 of the players on Team A score a goal, so:

5 players / (1/5) = A players

5 * (1/5) = A

A = 25

We also know that 1/11 of the players on Team B score a goal, so:

2 players / (1/11) = B players

2 * (1/11) = B

B = 22

So there are 25 players on Team A and 22 players on Team B.

For the given nonlinear equation for population growth ax where a>0,  a0 the equation exhibits exact compensation  whereas b) it has a non-trivial steady state.

The equation describes a population that grows at a rate that is proportional to its size. Specifically, the equation states that the population growth rate is equal to the product of a constant multiplier, a, and the size of the population, x. This means that when the population size increases, the rate of growth increases in proportion, causing the population to grow at a steady rate. the equation expresses a population growth rate that is proportional to the population size.

This means that when the population size is large enough, any further increases in the population size will be met with an equal increase in the population growth rate. This causes the population growth rate to remain constant, which is the definition of a non-trivial steady state

The answer is True. Finding a parametric description of the solution set of a linear system is the same as solving the system.

Finding a parametric description of the solution set of a linear system is equivalent to solving the system. A parametric description of the solution set of a linear system is a way of representing all solutions to the system in terms of a set of parameters. Solving a linear system involves finding the specific values of the variables that satisfy the constraints specified by the system. By finding a parametric description of the solution set, we are effectively solving the system and finding all possible solutions. In this sense, finding a parametric description of the solution set and solving the system are equivalent.

The horizontal distance between the base of the ladder and the wall is  8.9 feet.

Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles.

If we draw a right triangle with the ladder being the hypotenuse, the angle between the ladder and the ground is given as 69 degrees.

We can use trigonometric functions to solve for the horizontal distance between the base of the ladder and the wall.

Let x be the horizontal distance between the base of the ladder and the wall.

cos(69°) = x/26

Solving for x, we get:

x = 26 cos(69°)

Using a calculator, we find that cos(69°) ≈ 0.342, so:

x ≈ 26 × 0.342 ≈ 8.892

Therefore, the horizontal distance between the base of the ladder and the wall is approximately 8.9 feet.

False. Despite not being continuous at that point, a function can nevertheless be defined there. Functions that have a limit that is equal to their value at a particular point are said to be continuous functions. A function is said to be continuous at a particular location if it is. A function can, however, be defined at a location yet not be continuous there. For instance, even when a function is defined at a certain place, it may nevertheless have a finite jump there.

Megan tiled a rectangle with an area of 24 square centimeters, the Megan ‘s rectangle is 2 centimeters by 12 centimeters.

Megan tiled a rectangle with an area of 24 square centimeters,

A = 24 square centimeters

Area of the rectangle = length x breadth

A = l x b

24 = 12 x 2

Therefore, length= 12cm and breadth is 2 cm.

The area occupied by the rectangle within its perimeter may be calculated using the formula for the area of a rectangle. A rectangle's area is calculated by multiplying its length by its width (breadth). As a result, the area of a rectangle whose length and breadth are "l" and "w," respectively, may be calculated using the following formula. L * W = the rectangle's area.

As per unitary method, the amount it will cost to fill the pool is $2.68

The Unitary Method is a mathematical concept which encourages students to use one single rule or principle to solve a problem. It can be used to solve a variety of mathematical problems in algebra, geometry, and other areas.

In this case, the pool is 10 ft wide. To calculate the capacity of a pool with a rectangular shape, you need to multiply its width by its length and then multiply that result by its depth.

If we assume that the length and depth of the pool are both equal to 10 ft, then the capacity of the pool can be calculated as follows:

=> 10 ft x 10 ft x 10 ft = 1,000 cubic feet.

To convert the capacity to gallons, you need to divide

=> 1,000  / 7.48 = 133.89

gallons of water required to fill the pool.

Finally, to calculate the cost of filling the pool, you just need to multiply the number of gallons by the cost per gallon of water ($0.02).

=> 133.89 x 0.02 = 2.68

This gives us a total cost of $2.68 to fill the pool with water.

As the firm develops a specific sort of sensor and ships them in boxes of four, each sensor weighed 10 grams at first.

In its most basic form, an equation is a mathematical statement that indicates that two mathematical expressions are equal. 3x + 5 = 14, for example, is an equation in which 3x + 5 and 14 are two expressions separated by a 'equal' sign. A mathematical phrase with two equal sides separated by an equal sign is called an equation. An example of an equation is 4 + 6 = 10.

Here,

Let's call the original weight of each sensor "w". The total weight of 4 sensors would be 4w.

With the new design, each sensor weighs 9 grams more, so each sensor weighs w + 9 grams. The total weight of 4 sensors is 76 grams, so we can write an equation:

4(w + 9) = 76

Expanding the left-hand side and solving for w, we have:

4w + 36 = 76

4w = 40

w = 10

So each sensor originally weighed 10 grams as company manufactures a special type of sensor, and packs them in boxes of 4 for shipment.

Isaac has a 1/40 chance of winning the raffle, or a 2.5% chance. This indicates that he has a 2.5% probability of having his ticket chosen out of the 40 tickets that were sold. This is because there is only one raffle winner and it is impossible to predict which ticket will be picked.

It's also crucial to remember that his odds of winning are entirely independent of those of any other ticket holder; nobody else's ticket will affect the outcome of the raffle. As a result, Isaac has the same chance of winning as any other ticket holder. It's also vital to remember that regardless of how many tickets are sold, the likelihood of winning stays the same. Therefore, regardless of how many raffle tickets are sold, there is a 2.5% chance of winning.

By applying the properties of a parallelogram, it can be concluded that the quadrilateral would be a parallelogram since the opposite sides EF and GH are congruent and parallel.

Parallelogram is a 2-D shape formed by two pairs of sides, each of which is the same length (congruent) and parallel to its pair, and has two pairs of angles, each of which is equal to the angle opposite it.

Distance between two points is the length of the line segment that connects the two points in a plane.

d = √((x₂ – x₁)² + (y₂ – y₁)²)

Slope of a line is its vertical change divided by its horizontal change.

m = (y₂ - y₁) / (x₂ - x₁)

We have these points E (-7,-4), F (2,-3), G (0,-7), and H(-9,-8), and we want to prove that they formed a parallelogram.

To do so, we have to prove that EF and GH are congruent by calculating the distance between EF and GH:

EF = √((x₂ – x₁)² + (y₂ – y₁)²)

    = √((2 + 7)² + (-3 + 4)²)

    = √(9² + 1²)

    = √82

GH = √((x₂ – x₁)² + (y₂ – y₁)²)

     = √((-9 – 0)² + (-8 + 7)²)

     = √((-9)² + (-1)²)

     = √82

Because EF = GH = √82, they are congruent.

In the second step, we have to prove that EF and GH are parallel by calculating their slope:

slope of EF = (y₂ - y₁) / (x₂ - x₁)

                   = (-3 + 4) / (2 + 7)

                   = 1/9

slope of GH = (y₂ - y₁) / (x₂ - x₁)

                    = (-8 + 7) / (-9 – 0)

                    = 1/9

Because EF and GH have the same slope, they are parallel.

Thus, since the opposite sides EF and GH are congruent and parallel, so the quadrilateral would be a parallelogram.
