The length of the pool is 50 m, width 25 m, and the depth varies: 2.0 m is the minimum, but 3.0 m is the recommended depth. Olympic-size swimming pool contains 2,500,000 L of water, assuming a nominal depth of 2 m. It's around 550,000 imp gal and 660,000 US gal.

In order for (x - k) to be a factor of f(x), it must also be a zero of f(x). An integer-coefficient polynomial function's rational zeros are equal to the constant term's factor divided by the leading coefficient's factor.

When exponents, constants, and variables are joined using mathematical operations like addition, subtraction, multiplication, and division, the result is a polynomial (No division operation by a variable).

Answer:

Dilated point coordinates: (-1, -2)

Step-by-step explanation:

For a point (x, y), the dilation of the point by a scale factor of k centered around the origin will result in a point (x', y') where x' = kx and y' = ky

Depending on the value of k, the point will move either closer to the origin(k < 1) or farther away from the origin (k > 1)

Here we have the original point A(-4, -8) and k = [tex]\dfrac{1}{4}[/tex]

So the new point will move closer to the origin

The coordinates of the new point A' will be

[tex]x' = 4\cdot \dfrac{1}{4} = -1\\\\y' = -8\cdot \dfrac{1}{4} = -2\\[/tex]

So the dilated point A' will have coordinates (-1, -2)

The population standard deviation of {5, 8, 8, 5} is 3

A standard deviation (or σ) is a measure of how dispersed the data is in relation to the mean. Low standard deviation means data are clustered around the mean, and high standard deviation indicates data are more spread out.

here, we have.

The given population is

{5, 8, 8, 5}

The mean of the population = Sum of the terms /  Number of Terms

Find the values and substitute the values in the equation

Sum of terms = 5 + 8 + 8 +5

                      = 26

Number of terms = 4

The mean of the population= 26 / 4

                                              = 6.5

The variance of the population

= (5 - 6.5)^2 + (8 - 6.5)^2 + (8 - 6.5)^2 + (5 - 6.5)^2

= (-1.5)^2 + (1.5)^2 + 1.5^2 + (-1.5)^2

= 2.25 + 2.25 + 2.25 + 2.25

Answer:

A. To find a linear equation that models the temperature T when crickets are chirping at x chirps per minute, we need to use two points that are known. In this case, we are given that a cricket produces 120 chirps per minute at 70 degrees F and 168 chirps per minute at 80 degrees F. We can use these two points to find the slope and y-intercept of the line.

The slope of a line can be found using the formula: m = (y2 - y1) / (x2 - x1)

In this case, we can substitute the given values to get:

m = (168 - 120) / (80 - 70) = 48/10 = 4.8

The y-intercept of a line can be found using the formula: b = y - mx

We can use the point (70, 120) and the slope that we found to get:

b = 120 - (4.8 * 70) = -264

So the linear equation that models the temperature T when crickets are chirping at x chirps per minute is:

T = 4.8x - 264

B. If the crickets are chirping at 150 chirps per minute, we can substitute this value for x in the equation we found above to estimate the temperature:

T = 4.8x - 264

T = 4.8(150) - 264 = 720 - 264 = 456

So the estimated temperature is 456 degrees F.

C. The y-intercept of the line is -264, it represents the temperature when x (chirps per minutes) is zero. In this case it represents the temperature when the cricket is not chirping which is impossible, so it doesn't have any physical meaning.

the percentage of change is calculated using a formula, which gives you the solution as 40% of change in this question.

percentage of change = [ (new price - old price)/old price ] *100

= [(70-50)/50 ] *100

= [20/50 ] *100 = 40%

To calculate the percentage change we divide the change in price by the original value of the factor. By subratcting the old price from the new price, you will get either a positive or negative sign. If it is positive, the change is increasing while in case of negative sign, change results in decrease.

The senate has 4+22 = 26 members this year.

Let x be the number of Democrat members in the senate.

Last year, the number of Republican members was x+20

This year, the number of Republican members is (x+20) - 2 = x+18

This year, the number of members in the senate is 2/3*(x+18) = 2/3*x+12

So the number of members in the senate this year is x+12

To find the value of x, we can use the fact that the number of members in the senate this year is the same as last year.

x + (x + 20) = x + 12

x+x+20 = x + 12

2x = 8

x = 4

So the senate has 4 Democrat members and x+18 = 4+18 = 22 Republican members.

Therefore the senate has 4+22 = 26 members this year.

So the value of discriminant for √ 2x² − 5x + √ 2 = 0 is b. 17

The discriminant of a quadratic equation is the value of the expression under the square root in the quadratic formula. The quadratic formula is used to find the solutions of the equation of the form ax² + bx + c = 0, where a, b and c are constants. The solutions of the equation are given by x = (-b ± √(b² - 4ac))/ 2a. The value under the square root (b² - 4ac) is called the discriminant.

Given equation is √ 2x² − 5x + √ 2 = 0

The discriminant of the equation is the value of b² - 4ac, which is

b² - 4ac = (-5)² - 4 * (√2) * (√2) = 25 - 8 = 17

The angle of depression from the cruiser to the submarine is 63.43 degrees.

We can use the tangent function to find the angle of depression from the cruiser to the submarine.

The tangent function relates the opposite side (the vertical distance, or the depth) to the adjacent side (the horizontal distance) in a right triangle.

tan(angle of depression) = opposite/adjacent

In this case, the opposite side is the depth, or the vertical distance from the cruiser to the submarine, which is 2100 ft.

The adjacent side is the horizontal distance from the cruiser to the submarine, which is 900 ft.

tan(angle of depression) = 2100/900

Using a calculator we can find that tan(angle of depression) = 2.3333

Now we can use the inverse tangent function (arctan) to find the angle of depression:

the angle of depression = arctan (2100/900)

Using a calculator we can find that angle of depression = 63.43 degrees

Therefore, the angle of depression from the cruiser to the submarine is 63.43 degrees.

The measure of the angles in the parallelogram are 144 and 36 degrees.

What is a parallelogram?

A parallelogram is a quadrilateral with two pairs of parallel sides. The opposite sides of a parallelogram are of equal length and the opposite angles are also equal.

Having two sets of parallel sides makes a quadrilateral a parallelogram. A parallelogram has opposite sides that are the same length and angles that are the same size. Additionally, the internal angles on the same transverse side are supplementary. 360 degrees are equal to the total of all internal angles.

Two parallel pairs of sides make up a parallelogram, a quadrilateral. Four right angles form a parallelogram called a rectangle.

Angles in a parallelogram

a + b + c + d = 360

Opposite angles are equal, so

2a + 2(0.25a) = 360

2a + 0.5 = 360

2.5a = 360

a = 360/ 2.5

a = 144

the other angle = 180 - 144 = 36 degrees

To factorize 21x⁴y⁵ - 7x³y² + 14x³y⁴, we can factor out the greatest common factor (GCF) from all three terms. The GCF of the three terms is x³y².

So we can write:

21x⁴y⁵ - 7x³y² + 14x³y⁴ = x³y²(21x y³ - 7 + 14x²y²)

We can simplify further by combining the constants:

21x y³ - 7 + 14x²y² = 21x y³ + 14x²y² - 7

So the expression can be factorized as:

x³y²(21x y³ + 14x²y² - 7)

This is the factorization of 21x⁴y⁵ - 7x³y² + 14x³y⁴.
