Therefore , the solution of the given problem of equation comes out to be 2.61, -6.61 is the answer's numerical component.
A quadratic equation is what?Regression modelling uses the polynomial solution, which is x = ax2 + b + c=0, to solve problems with a single variable. The First Principle of Algebra states that there can only be one solution because it contains an additional order. There are both simple and complex solutions available. As the name suggests, a "non-linear algorithm" comprises four variables.
Here,
The equation y = x² + 4x - 12 has a parabola as its graph. To graph the solution to the equation x² + 4x = 12,
Rewrite the equation in the following format: y = x² + 4x - 12
Locate the x-values where the graph and x-axis overlap.
These x-values, which stand in for the equation's solutions, are those when y = 0.
Read off the graph's x-values and write them down as the equation's answers.
The solutions to the equation x² + 4x = 12 are about x = 2.61
and x = -6.61 (rounded to two decimal places), according to the graph of the equation y = x² + 4x - 12.

A, B & C form the vertices of a triangle, where
∠
CAB = 90°.
AB = 10.6 m and AC = 5.8m.
Evaluate
∠
ACB, giving your answer rounded to 3 SF.
Answer:
We can use the trigonometric function of sine to find the measure of angle ACB.
First, we note that sin(ACB) = opposite/hypotenuse = BC/AB.
To find BC, we use the Pythagorean theorem:
BC^2 = AB^2 - AC^2
BC^2 = (10.6 m)^2 - (5.8 m)^2
BC^2 = 67.24 m^2 - 33.64 m^2
BC^2 = 33.6 m^2
BC = sqrt(33.6) m
BC = 5.8 m (rounded to 1 decimal place)
Therefore, sin(ACB) = BC/AB = 5.8/10.6 = 0.5472
Using the inverse sine function on a calculator, we find:
ACB = sin^-1(0.5472)
ACB = 33.11°
Therefore, the measure of angle ACB is 33.11 degrees, rounded to 3 significant figures.

f(x)=4/3|x+2|−5 Which table shows values that are all true for the function?
Choose the 3rd table .
What is function ?Exactly one output value from a different set, known as the range, is what a function in mathematics does for each input value from the set known as the domain.
A function can be compared to a device that processes an input to create a particular output.
Given that the output value depends on the value of the input variable, the input value is sometimes referred to as the independent variable.
For instance, if a function is defined as
f(x) = 2x + 1, x
is the input variable and f is the output variable.(x).
What are variables ?A variable in mathematics is a symbol that designates a value or quantity that is subject to variation or change.
In order to solve equations and describe relationships between different quantities, variables are needed.
Variables in algebra are frequently denoted by letters like x, y, and z. They are used to express a relationship between two or more quantities or to represent undiscovered quantities that we are trying to locate.
For instance, x is the independent variable and y is the dependent variable in the equation y = 3x + 2.
According to question
Substitute X=14 into f(x) = 4/3 |x+2 | - 5
f (-14） = 4/3 |-14+2 | - 5
= 4/3 |-12 | - 5

hence when x=-14 fix=11
the first table is false
substitute x= -10 into f(x) = 4/3 |x+2 | - 5

what is the probability of the event when we randomly select a permutation of the 26 lowercase letters of the english alphabet where immediately precedes , which immediately precedes in the permutation?
The probability of selecting such a permutation is very low, only about 0.31%.
The probability of the event when we randomly select a permutation of the 26 lowercase letters of the English alphabet where 'm' immediately precedes 'n', which immediately precedes 'o' can be calculated as follows:
Firstly, we need to determine the total number of permutations of the 26 letters. Since there are 26 letters in the alphabet, there are 26! ways to arrange them.
Next, we need to determine the number of permutations where 'm' immediately precedes 'n', which immediately precedes 'o'. To do this, we can consider 'mno' as a single unit and then there are 24! ways to arrange the 24 units (23 individual letters and 1 unit of 'mno').
However, there are 3! ways to arrange 'mno' within the unit, so we need to multiply by 3!. Therefore, the total number of permutations where 'm' immediately precedes 'n', which immediately precedes 'o' is 24! x 3!.
Thus, the probability of randomly selecting a permutation where 'm' immediately precedes 'n', which immediately precedes 'o' is:
P = (24! x 3!) / 26!

Answer:
10^9 cubic meterslakeStep-by-step explanation:
You want to know the number of cubic meters in a cube that is 10^3 meters on each side, and whether that volume amounts to a pond, lake, or ocean.
VolumeThe volume of a cube is given by ...
V = s³
where s is the edge length.
The volume of interest is ...
V = (10³ m)³ = 10⁹ m³
The volume of oil is 10⁹ cubic meters.
LakeThe sizes of ponds and lakes vary, but we might consider a pond to be a body of water larger than about 150 square meters and less than 6 meters in depth. On the other hand, a lake will generally be larger than about 4000 square meters. An average size lake may be about 10 meters in depth.
If we put the given amount of volume in a space with a depth of 40 meters, it would cover an area of about 25 million square meters, roughly 6000 acres. That is the area of a circle about 7 km in diameter. This might be considered a medium-sized lake.
The oil would fill a medium-sized lake.

Additional comment
A "lake" is generally a body of water upwards of an acre in area. While an average lake in some areas is about 10 m deep, worldwide, the average is just over 40 m in depth. Some lakes are well over 20,000 acres in area.
A "pond" may be larger than a "lake", but will generally be smaller than 500 acres.

Equation of a circle :The equation of a circle is generally given by the formula:
=> (x - a)²+ (y - b)² = r²
Where (a, b) is the center of the circle, and r is its radius. The equation describes all the points (x, y) in the xy-plane that are a fixed distance r from the center point (a, b).
Here we have
A circle with centre O(2, 3) contains the point A(5, 11).
Since point A(5, 11) is located on the circle with center O(2, 3), use the distance formula to determine whether A is actually on the circle.
The distance between two points (x₁, y₁) and (x₂, y₂) is given by:
=> d = √(x₂ - x₁)² + (y₂ - y₁)²)
Using this formula, the distance between O(2, 3) and A(5, 11) is:
d = √(5 - 2)² + (11 - 3)²)
= √(3² + 8²)
= √(9 + 64)

This distance is the radius of the circle with center O.
Therefore, the equation of the circle is:
(x - 2)² + (y - 3)² = (√(73))²
x² - 4x + 4 + y² - 6y + 9 = 73
x² + y² - 4x - 6y - 60 = 0

This means that if the average weight of the men in the elevator is more than 180 lbs, the elevator would be overloaded.
To determine the average weight beyond which the elevator would be considered overloaded, we can follow these steps:
Find the total weight limit for 33 occupants: 5940 lbs.
Divide the total weight limit by the number of occupants to find the average weight per person: 5940 / 33 = 180 lbs.
Now, we need to find the difference between the average weight per person (180 lbs) and the mean weight of the population (166 lbs): 180 - 166 = 14 lbs.
Since we have the difference and the standard deviation (26 lbs), we can now calculate the Z-score:
Z = (difference) / (standard deviation) = 14 / 26 ≈ 0.54.
The average weight beyond which the elevator would be considered overloaded is 180 lbs.
The corresponding Z-score for this weight is approximately 0.54.

The equation that represents the volume of water in cubic meters after T minutes of water being pumped out is V = -1.5T + 30.
The given data shows that the volume of water is decreasing as time goes on. Therefore, we need to use a function that is decreasing with respect to time. One such function is a linear function.
Let V be the volume of water in cubic meters after T minutes of water being pumped out. Then, we can use the two points (0, 30) and (15, 7.5) to find the equation of the line that represents the volume of water in terms of time.
The slope of the line is
slope = (change in volume) / (change in time) = (7.5 - 30) / (15 - 0) = -1.5 cubic meters per minute
The y-intercept of the line is the volume of water when time is zero, which is 30 cubic meters.

The distance between the ladder's bottom and the wall is around 7.5 feet (rounded to the nearest tenth).
What is Pythagorean Theorem?The Pythagorean theorem is a basic mathematical theorem that describes the connection between the sides of a right triangle. It asserts that the square of the length of the hypotenuse (the side opposite the right angle) in a right triangle is equal to the sum of the squares of the other two sides.
The Pythagorean theorem can be stated mathematically as:
[tex]C^2 = A^2 + B^2[/tex]
where "C" indicates the length of the hypotenuse and "A" and "B" represent the lengths of the other two sides of the right triangle.
In this scenario, the ladder is the hypotenuse of a right-angled triangle, with the wall constituting one side and the distance between the bottom of the ladder and the wall forming the other.
Given,
Length of the ladder (hypotenuse) = 15 feet
Height of the ladder on the wall (one side) = 13 feet
Let's call the distance between the bottom of the ladder and the wall "x" feet.
Using Pythagorean theorem ,
[tex]15^2 = 13^2 + x^2[/tex]
225 = 169 + [tex]x^{2}[/tex]
[tex]x^{2}[/tex] = 225 - 169
[tex]x^{2}[/tex] = 56
x = [tex]\sqrt{56}[/tex] (taking the square root of both sides)
x [tex]$\approx$[/tex] 7.5 feet
As a result, the distance between the bottom of the ladder and the wall is around 7.5 feet (rounded to the nearest tenth).

Find the avatar rate of change f(x)=3√x-1 +2; 9 ≤ x ≤ 65
Answer: To find the average rate of change of the function f(x) over the interval [9, 65], we can use the formula:
average rate of change = (f(b) - f(a)) / (b - a)
where a = 9, b = 65, f(a) = f(9) = 3√8 + 2, and f(b) = f(65) = 3√64 + 2.
Plugging in these values, we get:
average rate of change = (f(65) - f(9)) / (65 - 9)
average rate of change = (3√64 + 2 - 3√8 - 2) / 56
average rate of change = (3(4) + 2 - 3(2) - 2) / 56
average rate of change = (12 - 4) / 56
average rate of change = 8 / 56
average rate of change = 1 / 7
Therefore, the average rate of change of the function f(x) over the interval [9, 65] is 1/7.

Scientists measure a bacteria population and find that it is 10,000. Five days later, they
find that the population has doubled. Which function f could describe the bacteria
population d days after the scientists first measured it, assuming it grows exponentially?
A. f(d) 10,000. 2ª
B. f(d) = 10,000. (√2)ª
C. ƒ(d) = 10,000 • (-)ª
D. f(d) = 10,000.25d
=
S
Answer:
Hm
Step-by-step explanation:
The bacteria population is observed to double after five days, which means that its growth rate is 100% over a period of five days. This corresponds to a daily growth rate of r = 100%/5 = 20%.
If the initial population is 10,000, then the bacteria population after d days can be modeled by the exponential function:
f(d) = 10,000 * (1 + r/100)^d
Substituting r = 20% and simplifying, we get:
f(d) = 10,000 * (1.2)^d
Therefore, the correct option is:
D. f(d) = 10,000 * (1.2)^d

Hence, OC bisects AB, as congruent parts of congruent triangles are equal.
What is congruency in figures?When two or more geometric figures are similar in size, form, and orientation, this is referred to as congruency in geometry. Two figures can be overlaid on one another by translation, rotation, and/or reflection when they are congruent because they are almost similar to one another and do not alter in size, form, or orientation.
For the given problem, the complete steps of proof with reasoning are:
(a) OC is perpendicular to AB in circle O (given). i.e ∠OCA and ∠OCB are right angles.
Reason: This is given in the problem statement. It establishes that OC forms a right angle with AB at point C in circle O. i
(b) Draw OA and OB (construction).
Reason: This is a construction step that introduces radii OA and OB from the center O of the circle to points A and B on the circle. This sets up the framework for the subsequent steps and establishes the positions of A and B in relation to the circle and the perpendicular OC.
(c) OA = OB (radii of the same circle are equal).
Reason: Radii of the same circle are always equal in length. This is a basic property of circles, where all radii have the same length, which can be stated as OA = OB based on the definition of a circle.
(d) OC = OC (Reflexive Property of Equality)
Reason: It is a property of line segments that they are equal to themselves. This is known as the Reflexive Property of Equality, which states that any quantity is equal to itself.
(f) AC = BC (common side of congruent triangles).
Reason: AC and BC are line segments that are both radii of the same circle, and OA = OB (Step c). Therefore, by the definition of congruent segments, AC = BC.
(e) Triangle ACO is congruent to triangle BCO (HL congruence criterion for right triangles).
Reason: Angle ACO and angle BCO are both right angles based on the given information that OC is perpendicular to AB (Step a). Also, AC = BC (Step d) and OA = OB (Step c). Therefore, by the Hypotenuse-Leg congruence criterion for right triangles, triangle ACO is congruent to triangle BCO.
(g) OC bisects AB (congruent parts of congruent triangles are equal).
Reason: Since triangle ACO is congruent to triangle BCO (Step e), the corresponding parts of congruent triangles are equal. In this case, OC is a common side (hypotenuse) of both triangles, and AB is a side of both triangles. Therefore, by the definition of a segment bisector, OC bisects AB.

using a standard deck of playing cards, how many ways are to form a 5-card hand with 2 pairs (i.e. pair of one value, a pair of a different value, and a fifth card of some other value)? what if we require the pairs to be the same color (i.e spade with clubs and diamond with hearts)?
From a "standard-deck" of "playing-cards", the number of ways which are required to form a "5-card" hand with "2-pairs" is 123,552 ways.
A "Standard-Deck" of playing cards generally consists of 52 cards, divided into four suits: hearts, diamonds, clubs, and spades. Each suit contains 13 ranks: Ace, 2 through 10, and three face cards.
To form a 5-card hand with 2 pairs from a standard deck of playing cards, we break it down into two steps:
Step(1) : Select the values for the two pairs.
There are 13-ranks in a standard deck of playing cards, ranging from 2 to 10, and then Jack, Queen, King, and Ace, for a total of 13 possible values.
We need to select 2 of these values to form the two pairs. The number of ways to do this is "C(13, 2)" which is : 78,
So, there are 78 ways to select the values for the two pairs.
Step(2) : Select the specific-cards for each pair and the fifth card.
For each pair, we need to select 2 cards of that value from the 4 cards of each rank in the deck.
The number of ways to do this is "C(4, 2)" which is : 6,
So, there are 6 ways to select the specific cards for each pair.
Finally, for the fifth-card, we can choose any of the remaining "44-cards" in the deck (after selecting the 8 cards for the two pairs).
So, total number of ways to form a "5-card" hand with "2-pairs" from a standard deck of playing cards is,
⇒ 78 × 6 × 6 × 44 = 123,552 ways,
Therefore, the required number of ways are 123,552 ways.
