f(x)=x(squared) - 9
enter your answer in {brackets} from least to greatest
Answers
The zeros of the function are x = 3 and x = -3
How to determine the zeros of the function?The equation of the function is given as
f(x) = x(squared) - 9
Rewrite the equation properly
So, we have the following equation
f(x) = x^2 - 9
Express the equation as a difference of two squares
So, we have the following equation
f(x) = (x - 3)(x + 3)
Set the equation to 0
(x - 3)(x + 3) = 0
Split
x - 3 = 0 and x + 3 = 0
Solve for x
x = 3 and x = -3
Hence, the solutions are -3 and 3

The order of the numbers from lowest to highest is 4.68 × 10⁻⁶, 8.34 × 10⁻², 1.2 × 10⁷, 3.24 × 10⁹ and 5.48 × 10⁹
What is the order of the numbers from lowest to highest?The given numbers are expressed in standard form. Standard form is a way of writing numbers as a power 10 e.g 100 = 1 × 10² and 0.01 = 1 × 10⁻².
So converting the numbers back to ordinary numbers will be useful.
To do this, we will multiply or divide the powers of 10 with the decimal numbers.
We will multiply if the power is positive e.g 2.4 x 10² = 2.4 x 100 = 240 and divide if the power is negative 2.4 x 10⁻² = 2.4/100 = 0.024
3.24 × 10⁹ = 3.24 x 1000,000,000 = 3240000000
4.68 × 10⁻⁶ = 4.68 / 1000000 = 0.00000468
5.48 × 10⁹ = 5480000000
8.34 × 10⁻² = 8.34/100 = 0.0834
1.2 × 10⁷ = 12000000
Therefore, arranging from lowest to highest. We have:
4.68 × 10⁻⁶, 8.34 × 10⁻², 1.2 × 10⁷, 3.24 × 10⁹ and 5.48 × 10⁹

Items are a fundamental component of an OracleAS Portal page. Item types are used to categorize items. Item types determine the contents of an item as well as the information kept about it. Users with the necessary permissions can add an item or create an item type. The properties of an object type define the information stored about it. The item types that you can add to a page differ depending on whatever item types the page group administrator has included in the page group. If the built-in item types are insufficiently flexible, users with proper access can develop new custom item kinds to fulfill their needs.

* Both factors are negative or zero
The answer can come from any of the conditions stated above, so the solution is the OR combination of the individual solutions.
The first condition states:
x - 4 ≥ 0 AND x + 4 ≥ 0
This leads to the solution:
x ≥ 4 AND x ≥ -4
If x must be greater or equal to 4 and greater or equal to -4, then the AND combination gives the solution: x ≥ 4
The second condition states:
x - 4 ≤ 0 AND x + 4 ≤ 0
This leads to:
x ≤ 4 AND x ≤ -4
The AND combination gives the second solution x ≤ -4
The final solution is the first solution OR the second solution, that is:

when x = 4, y = 2
4(4) + 2 = 18 which is not less than 2

Find all critical points of the function g(x)=sin^2(11x). Express your answer in terms of pi.
(Use symbolic notation and fractions where needed. Use n for all integer values.)
Answers
Critical points are the points where the slope of the function is zero thus at θ = 0,π/22,π11,3π/22 ... will be the critical points of function g(θ) = sin²(11θ).
What is the slope?A slope is a tangent or angle at a point and a slope is the intensity of inclination of any geometrical lines.
Slope = Tanx where x will be the angle from the positive x-axis at that point.
As per the given function,g(θ) = sin²(11θ).
The critical points are the points where the slope of the tangent of the function is zero.
The slope of the tangent of a function is the first derivative thus,
g'(θ) = 0 ⇒ 2× 11 sin(11θ)cos(11θ) = 0
Sin(11θ) = 0 ⇒ θ = 0
Cos(11θ) = 0 ⇒ 11θ = π/2
θ = π/22
Since, sinusoidal functions are repeating thus,
Next critical point = π/22 + π/22 = π/11 and so on.
Hence "Critical points are the points where the slope of the function is zero thus at θ = 0,π/22,π11,3π/22 ... will be the critical points of function g(θ) = sin²(11θ)".

What is Surface area?
The space occupied by a plat surface is called Surface area.
Given that;
Surface area (S) = 2πr² + 2πrh
Where, r is the base radius and h is the height.
Now, When Surface area = 175 square inches
Radius (r) = 6 inches.
Then, We can calculate height as;
Since,
Surface area (S) = 2πr² + 2πrh
175 = 2 × 3.14 × (6)² + 2 × 3.14 × 6 h
175 = 226.08 + 37.68h
175 - 226.08 = 37.68 h
- 51.08 = 37.68 h
h = - 51.08 / 37.68
h = - 1.35

Geometry help for A and B. Answer B approximate volume?
Answers
The volume of the silo with given height and diameter is 4374π ft or 13734.36 ft. (approximately).
What is volume?
Volume is a measurement of 3-D space that is occupied. Numerous imperial units or SI-derived units, such as the cubic meter and liter, are frequently used to quantify it numerically (such as the gallon, quart, cubic inch). Volume and length (cubed) have a symbiotic relationship. The volume of a container is typically thought of as its capacity, not as the amount of space it takes up.
Given in the question,
The diameter of the cylindrical silo is 18 ft,
and its height is 54 ft.
Volume of a cylinder can be calculated using the formula:
[tex]V = \pi r^2 h[/tex]
Here, V = volume, r = radius, h = height,
We know that, radius is half of diameter. So, radius = 18/2 = 9 ft
Putting the given value in the formula:
[tex]V = \pi 9^2 \times 54[/tex]
[tex]V = \pi \times 81 \times 54[/tex]
V = 4374π ft.
Putting the value of π as 3.14 (approximately)
So, volume of the silo becomes 13734.36 ft.

An indifference curve is a graph that illustrates numerous pairings of two goods or commodities that leave the customer equally well off or satisfied—hence indifferent—when it comes to owning any pairing of the two items that is represented along the curve.
A consumer must give up more of one good in order to buy more of another, hence an indifference curve will always have a negative slope.
