The volume of water in the pool is 10230 cubic feet.

Given : Swimming pool is circular with a 40-ft diameter. The depth is constant along east-west lines and increases linearly from 5 ft at the south end to 10 ft at the north end.

To find : The volume of water in the pool?

Swimming pool is circular with a 40-ft diameter.

The radius of the pool is 40/20 = 20 ft

The depth is constant along east-west lines and increases linearly from 5 ft at the south end to 10 ft at the north end.

Depth average is:

Da = 5+10/2

= 7.5

The volume is given by:

V = π × r² × Da

V = 3.41 × (20)² × 7.5

V = 10230 ft²

The volume of water in the pool is 10230 ft² cubic feet.

The statement that is true is: f(x) = (2x^2 + 25)(x + a) has zeros of 25 and a. In this polynomial, the zeros are the values of x that make the polynomial equal to zero.

The given polynomial is a product of two factors, (2x^2 + 25) and (x + a). For the entire polynomial to be zero, at least one of the factors must be zero. The first factor, 2x^2 + 25, does not have any real zeros because it represents a quadratic equation with a positive leading coefficient, which means it opens upwards and does not cross the x-axis. However, the second factor, x + a, will be zero when x = -a. Therefore, the zeros of the polynomial f(x) = (2x^2 + 25)(x + a) are 25 and -a.

The given statement correctly identifies the zeros of the polynomial f(x) = (2x^2 + 25)(x + a) as 25 and a. This is because the zeros of a polynomial correspond to the values of x for which the polynomial equals zero. In this case, the polynomial is a product of two factors. The first factor, 2x^2 + 25, does not have any real zeros. However, the second factor, x + a, will be zero when x = -a. Therefore, the zeros of the entire polynomial are 25 and -a.

Using Pythagoras Theorem, The height of the screen is approximately 27.18 inches.

Pythagoras Theorem is the way in which you can find the missing length of a right angled triangle.

We can use the Pythagorean theorem to solve this problem. Let's call the height of the screen "h". Then, according to the Pythagorean theorem, we have:

\(h^2 + 32^2 = 42^2\)

Simplifying this equation, we get:

\(h^2 + 1024 = 1764\)

Subtracting 1024 from both sides, we get:

\(h^2 = 740\)

Taking the square root of both sides, we get:

\(h = \sqrt{(740)}\)

Using a calculator to approximate the square root, we get:

h ≈ 27.18 inches

Hence, the height of the screen is approximately 27.18 inches.

The conical surface is the correct answer as it allows for slopes ranging from 20:1 to 50:1. The FAR Part 77 imaginary surface that has slopes that may range from 20:1 to 50:1 is the conical surface.

The conical surface is a three-dimensional surface defined by a combination of horizontal and inclined planes. It extends upward and outward from the end of the primary surface and has varying slope requirements. The slope of the conical surface represents the ratio of the change in elevation to the horizontal distance. A slope of 20:1 indicates that for every 20 units of horizontal distance, there is a 1-unit increase in elevation.

Similarly, a slope of 50:1 means that for every 50 units of horizontal distance, there is a 1-unit increase in elevation. Therefore, the conical surface is the correct answer as it allows for slopes ranging from 20:1 to 50:1.

Step-by-step explanation:

the given equation defines a paraboloid that lies below the plane z=0. Specifically, it is situated above the xy-plane, which means that the z-values of all points on the surface are greater than or equal to zero.

we can break down the equation z=18-2x^2-2y^2. This equation represents a paraboloid with its vertex at (0,0,18) and axis of symmetry along the z-axis. The first term 18 is the z-coordinate of the vertex and the last two terms -2x^2 and -2y^2 determine the shape of the paraboloid.

Since the coefficient of x^2 and y^2 terms are negative, the paraboloid is downward facing and opens along the negative z-axis. Therefore, all points on the paraboloid have z-values less than 18. Additionally, since the paraboloid is situated above the xy-plane, its z-values are greater than or equal to zero.

the paraboloid defined by the equation z=18-2x^2-2y^2 is situated below the plane z=0 and above the xy-plane. Its vertex is at (0,0,18) and it opens along the negative z-axis.

The measure of the given arc HJK is 186°.

Given measurement of the angle G = (4y - 11)°

The measurement of the angle J = (3y + 9)°

The measurement of the angle K = (x + 21)°

The measurement of the angle H = 2x°

From the below attached pic rule, in the given diagram angle J + angle G = 180°

So, J + G = 180°

= (4y - 11)° +  (3y + 9)° = 180°

= 7y -2 = 180°

= 7y = 182°

y = 182°/7 = 26°

By substituting y value which is "26°" in the angle G and J we can obtain their measurements as angle G = 93° and angle J = 87°.

Similarly, to find the value of x,

H + K = 180°

2x + (x + 21)° = 180°

3x + 21° = 180°

3x = 159°

x = 159°/3 = 53°.

By substituting x value which is "53°" in the angle H and K we can obtain their measurements as angle H = 106° and angle K = 74°

To find the measurement of arc, from the second attached image we can know that the angle of G is opposite to arc HJK. So, the relation is as follows,

measurement of arc HJK = 2 * angle of G

HJK = 2 * 93°

HJK = 186°.

From the above solution, we can conclude that the measurement of arc HJK is 186°

Answer:

Step-by-step explanation:

The correct option is the third one; (14, 4); The vertex represents the maximum profit.

For a general quadratic equation

y = ax² + bx + c

The vertex is at the x-value:

x = -b/2a

Here the quadratic function is:

f(x)=  -x² + 28x - 192

The vertex is at:

x = -28/2*-1 = 14

Evaluating in x= 14 we get:

f(14) = -14² + 28*14 - 192 = 4

So the vertex is at (14, 4), and because the leading coefficient is negative, this is the maximum profit.

To begin, we know that the median of the original collection of five positive integers is 4, which means that the middle number is 4. We also know that the unique mode is 3, which means that there is only one number in the collection that occurs more frequently than any other number.

Let's call the five positive integers in the original collection a, b, c, d, and e.

Since the mean of the original collection is 4.4, we can set up the equation:

(a+b+c+d+e)/5 = 4.4

Multiplying both sides by 5 gives:

a+b+c+d+e = 22

We also know that the mode is 3, which means that one of the numbers in the collection must be 3. Let's assume that a = 3, then we have:

3+b+c+d+e = 22

b+c+d+e = 19

Since the median is 4 and 3 is the unique mode, we can conclude that b, c, d, and e must be either 4 or 5. However, since there is only one unique mode, we know that there is only one number in the collection that is equal to 3. Therefore, we can conclude that the collection of five positive integers must be: 3, 4, 4, 4, 5.

If we add 8 to this collection, the new collection becomes: 3, 4, 4, 4, 5, 8. The new collection has six numbers, so the median is now the average of the two middle numbers. Since the middle two numbers are 4 and 5, the median is (4+5)/2 = 4.5.

Therefore, the new median is 4.5, expressed as a decimal to the nearest tenth.

Answer:

The amount she saves is 25% of her income

Step-by-step explanation:

She is paid $11 per hour

She works 9 hours per day

and for 24 days per month

So, she works 9(24) hours per month

= 216 hours per month

Now, she is paid $11 hourly, so for 216 hours,

she will have 11(216) = $2376

Total income = $2376 per month

Saving = $594 per month

As a percentage, we divide the savings by the total income,

savings/(total income) = 594/2376 = 1/4 = 0.25

Hence we get 25%
