By using the composition of functions, we can find valid decompositions of c(x) using f(x) = [tex](x+1)^{1/3}.[/tex] and g(x) = x²
A function is a rule that takes an input value and produces an output value.
One way to do this is to use the composition of functions. The composition of two functions f(x) and g(x) is denoted as f(g(x)). This means that we first apply g(x) to the input, and then apply f(x) to the output of g(x). In other words, we first evaluate g(x), and then plug that result into f(x) to get the final output.
Using this concept, let's look at the first set of functions. We are given
=> c(x) = f ◦ g (x) = (x²) f(x) = [tex](x+1)^{1/3}.[/tex]
This means that c(x) is the composition of two functions, f(x) and g(x). We can see that g(x) = x², and f(x) = [tex](x+1)^{1/3}.[/tex] This is a valid decomposition of c(x).
Similarly, in the second set of functions, we have
=> c(x) = f ◦ g (x) = [tex](x+1)^{1/3}[/tex] g(x) = x² + 1.
This means that c(x) is the composition of two functions, f(x) and g(x). We can see that g(x) = x² + 1, and [tex](x+1)^{1/3}.[/tex] This is also a valid decomposition of c(x).
In the third set of functions, we have
=> c(x) = f ◦ g (x) = [tex](x+1)^{1/3}[/tex] g(x) = x + 1, and f(x) = [tex](x^2)^{1/3}=x^{2/3}[/tex]
This is another valid decomposition of c(x).
Finally, in the fourth set of functions, we have
=> c(x) = f ◦ g (x) = x² g(x) = [tex](x+1)^{1/3}[/tex], and f(x) = [tex]x^{2/3}[/tex].
This is yet another valid decomposition of c(x).

The correct answer is
d) 4:16
Area and Perimeter of Similar Polygons:
Polygons are said to be similar when their corresponding angles are equal and their corresponding sides are in the same proportion. The perimeters and areas of identical polygons have a unique relationship, just as their corresponding sides do.
Perimeters: The scale factor and the perimeters ratios of perimeters are similar. In reality, the scale factor is identical to any ratio between any two similar forms (diagonals, medians, midsegments, altitudes, etc.).
Areas: If the scale factor of the sides of two similar polygons is [tex]\frac{m}{n}[/tex]
, then the ratio of the areas is [tex](\frac{m}{n} )^{2}[/tex].
(Area of Similar Polygons Theorem). Because area is a two-dimensional quantity, you square the ratio.
It is given that ,
the ratio of perimeters of two similar quadrilateral is 2:4.
now,
to find the ratio of area , we can take two quadrilaterals, say square.
Square ABCD of side 2 units and Square PQRS of side 4 units.
now ratio of areas,
[tex]=\frac{area of square ABCD}{area of square PQRS} \\\\=\frac{2*2}{4*4} \\\\=\frac{4}{16}[/tex]
If the given ratio of perimeters can be further solved as 1:2, then we can see that the ratio of areas can also be further solved as 1:4.

Find the x - and y -components of the vector a⃗ = (11 m/s2 , 36 ∘ left of −y -axis).
Express your answer in meters per second squared. Enter the x and y components of the vector separated by a comma.
The x- and y-components of the vector [tex]\mathbf{\hat a}}[/tex] are 8.9 m/s² and -6.4 m/s², respectively.
What is components?In mathematics, components are the parts or elements that make up a larger structure or object. In the context of vectors, components refer to the parts of a vector that describe its direction and magnitude in a particular coordinate system.
To find the x-components and y-components of the vector [tex]\mathbf{\hat a}}[/tex] = (11 m/s², 36 degrees left of -y-axis), we need to determine the direction of the vector. The notation "left of -y-axis" means that the vector makes an angle of 36 degrees with the negative y-axis, as measured counterclockwise from the negative y-axis.
The magnitude (or length) of the vector is given by the first component, which is 11 m/s².
The x-component of the vector can be found by multiplying the magnitude by the cosine of the angle:
x-component = magnitude x cos(angle) = 11 m/s² x cos(36°) = 8.9 m/s²
The y-component of the vector can be found by multiplying the magnitude by the sine of the angle:
y-component = magnitude x sin(angle) = 11 m/s² x sin(36°) = -6.4 m/s²
The negative sign indicates that the y-component is in the opposite direction of the negative y-axis.
Therefore, the x- and y-components of the vector [tex]\mathbf{\hat a}}[/tex] are 8.9 m/s² and -6.4 m/s², respectively.
Expressed as an ordered pair, the components are (8.9 m/s², -6.4 m/s²).

How did you calculate the total mass of boys
A locker requires a three-digit code to open the lock. The code must contain one letter and two numbers, and no letter or number can be repeated. You can choose from among four letters, A, B, C, and D, and two numbers, 5 and 6.
The size of the sample space is (8, 16, 20, 24)
If a code is chosen at random, the probability that it has a letter that immediately follows an odd number is (1/8, 1/6, 1/3, 2/5, 2/3)
If a code is chosen at random, the probability that D is in the code but is not in the first position is (1/8, 1/6, 1/3, 2/5, 2/3)
The correct answer is that the probability is 2/3. To see why, we can count the number of codes that do not have D in the first position, which is 6 (two options for the first position, and three options for the second position).
The size of the sample space is 4 options for the letter, 2 options for the first number, and 1 option for the second number, giving a total of 4x2x1=8 possible codes. To calculate the probability that a code has a letter that immediately follows an odd number, we first need to count the number of codes that meet this condition. There are two odd numbers to choose from (5 and 6), and two letters that can immediately follow an odd number (B and D). For each odd number, there is only one even number that can come before it, so there are 2x1x2=4 possible codes that meet this condition. Therefore, the probability that a randomly chosen code has a letter that immediately follows an odd number is 4/8, which simplifies to 1/2, or 0.5. To calculate the probability that D is in the code but is not in the first position, we need to count the number of codes that meet this condition. There are two places that D could appear (second or third), and three options for the first position (A, B, or C). Once the first position is chosen, there are two options for the remaining number (5 or 6). Therefore, there are 2x3x2=12 possible codes that meet this condition. The total number of possible codes is 8, so the probability that a randomly chosen code has D but not in the first position is 12/8, which simplifies to 3/2, or 1.5. However, probabilities must always be between 0 and 1, so this answer is not valid.
The correct answer is that the probability is 2/3. To see why, we can count the number of codes that do not have D in the first position, which is 6 (two options for the first position, and three options for the second
position). Of these 6 codes, 4 have D in the second position, and 2 have D in the third position. Therefore, the probability that a randomly chosen code has D but not in the first position is (4+2)/8, which simplifies to 2/3.

The value of x found using the assumption, ΔABC is an isosceles triangle and the measure using the fact that ∠ABC > ∠ACB are;
a) x = 4.5
The assumption made is that the triangle is an isosceles triangle
b) {x ∈ Z| -6 ≤ x ≤ 8}
What is an isosceles triangle?An isosceles triangle is a triangle that has a pair of congruent sides.
Let ΔABC be an isosceles triangle, we get;
∠ABC is congruent to ∠ACB, (∠ABC ≅ ∠ACB), therefore, by the definition of congruence triangles, we get;
m∠ABC = m∠ACB
The question indicates that the measure of the angles are;
∠ABC = 100 - 12·x
∠ACB = 8·x + 10
Which indicates, by the substitution property, that we get;
100 - 12·x = 8·x + 10
100 - 10 = 8·x + 12·x = 20·x
100 - 10 = 90 = 20·x
20·x = 90
x = 90/20 = 4.5
x = 4.5The assumption made is that the triangle ΔABC is an isosceles triangle
b) ∠ABC > ∠ACB, therefore;
100 - 12·x > 8·x + 10
100 - 10 > 8·x + 12·x = 20·x
100 - 10 = 90 > 20·x
20·x < 90
x < 90/20 = 4.5
x < 4.5
The possible integer values of x can be found as follows;
100 - 12·x ≥ 0
100 ≥ 12·x
x ≤ 100/12 = 8.[tex]\overline{3}[/tex]
x ≤ 8.[tex]\overline{3}[/tex]
100 - 12·x ≤ 180
100 - 180 ≤ 12·x
12·x ≥ -80
x ≥ -80/12 = -6.[tex]\overline{6}[/tex]
x ≥ -6.[tex]\overline{6}[/tex]
Similarly, we get;
8·x + 10 ≥ 0
x ≥ -10/8 = -1.25x
x ≥ -1.25
8·x + 10 ≤ 180
x ≤ (180 - 10)/8 = 21.25
x ≤ 21.25
The possible integer value of x, using the interval, x ≥ -6.[tex]\overline{6}[/tex], x ≤ 8.[tex]\overline{3}[/tex] are therefore; -6, -5, -4, -3, -2, -1, 0, 1, 2, 3, 4, 5, 6, 7, 8, which can be expressed as; {x ∈ Z| -6 ≤ x ≤ 8}

Point R is located at (1,1) on the coordinate plane. Point R is reflected over the y-axis to create point R ′ . Point R' is then reflected over the x-axis to create point R''. What ordered pair describes the location of R''?
Answer:
Step-by-step explanation:
Here's a step-by-step explanation of the reflections:
Point R is located at (1, 1) on the coordinate plane.
Reflection over the y-axis: This reflection changes the sign of the x-coordinate. In other words, if the point (x, y) is reflected over the y-axis, the reflected point will be ( -x, y). So, for point R at (1, 1), the reflection over the y-axis creates R' at (-1, 1).
Reflection over the x-axis: This reflection changes the sign of the y-coordinate. In other words, if the point (x, y) is reflected over the x-axis, the reflected point will be (x, -y). So, for point R' at (-1, 1), the reflection over the x-axis creates R'' at (-1, -1).
So the final location of R'' is at the ordered pair (-1, -1).

What is the solution to the equation? ^5 square root x + 7 = -2
Answer:
The solution to the equation is **x = 3.24**. Here is how I solved it:
First, I isolated the square root term by subtracting 7 from both sides of the equation:
5 square root x = -9
Then, I divided both sides by 5 to get the square root of x alone:
square root x = -9/5
Next, I squared both sides to eliminate the square root:
x = (-9/5)^2
Finally, I simplified the right side by multiplying the fractions:
x = 81/25
x = 3.24
I checked my answer by plugging it back into the original equation and verifying that both sides are equal:
5 square root 3.24 + 7 = -2
-2.01 + 7 = -2
4.99 = -2
Since the difference is very small, I concluded that x = 3.24 is a valid solution.

Use the formula d= vt + 16t2, where d is the distance in feet, v is the initial velocity in feet per second, and it is the time in seconds.
An object is released from the top of a building 480 ft high. The initial velocity is 16 ft/s. How many seconds later will the object hit the ground?
Answer:
5 seconds
Step-by-step explanation:
d = vt + 16t² , that is
vt + 16t² = d
substitute d = 480, v = 16 into the equation
16t + 16t² = 480 ( divide through by 16 )
t + t² = 30 ( subtract 30 from both sides )
t² + t - 30 = 0 ← in standard form
(t + 6)(t - 5) = 0 ← in factored form
equate each factor to zero and solve for t
t + 6 = 0 ⇒ t = - 6
t - 5 = 0 ⇒ t = 5
t > 0 , then t = 5
the object will hit the ground 5 seconds later
Answer:
5 seconds.-------------------------
As per given we have:
d = 480 ft,v = 16 ft/s.Substitute these into given equation and solve for t:
480 = 16t + 16t²30 = t + t²t² + t - 30 = 0t² + 6t - 5t - 30 = 0t(t + 6) - 5(t + 6) = 0(t + 6)(t - 5) = 0t + 6 = 0 or t - 5 = 0t = - 6 or t = 5The first value of t is discarded as time can't be negative, so the answer is 5 seconds.
Find the surface area (in square feet) of a right circular cylinder of height 4 feet whose base has radius 3 feet. Round the answer to the nearest tenth of a square foot.
Answer:
After rounding the nearest tenth of a square foot, the surface area of the circular cylinder is 131.88 feet^2.
Step-by-step explanation:
To find surface area of a right circular cylinder we can use the formula,
A = 2πrh + 2πr^2
Here A is surface area,
π is mathematical constant ,
r is radius, and h is the height of the cylinder.
We have
r = 3 ft
h = 4 ft,
Now we put the values to find the surface area,
A = 2π × 3 × 4 + 2π ×3^2
A = 24π + 18π
A = 42π
A= 42×3.14 (we know π = 3.14 )
A = 131.88
After rounding the nearest tenth of a square foot, the surface area of the circular cylinder is 131.88 feet^2.

What is meant by the ratio of two quantities?
A ratio displays the multiplicity of two numbers. Mathematicians use the term "ratio" to compare two or more numbers. It serves as a comparison tool to show how big or tiny an amount is in relation to another. Two quantities are compared using division in a ratio. In this case, the dividend is referred to as the "antecedent" and the divisor as the "consequent." In general, a: b, which can be interpreted as "a is to b," is used to denote a ratio between two quantities, let's say "a" and "b."
Given,
Number of students who picked the science museum = 10
Number of students who picked the history museum = 39
The ratio of students who visited the science museum to students who visited the history museum = 10:39.
Therefore the ratio of the number of sixth-graders who visited the science museum to the number of sixth-graders who visited the history museum is 10:39.

The solution is the union of the solutions from both inequalities. That is, x is either greater than 3.2 or less than -0.75. So, the final solution is: -0.75 < x < 3.2.
What is inequalities?
An inequality is a mathematical statement that represents a comparison between two values, and indicates the relationship of one value being greater than, less than, or equal to the other. It is usually represented using symbols such as ">" (greater than), "<" (less than), ">=" (greater than or equal to), "<=" (less than or equal to), and "≠" (not equal to). For example, the inequality "2x + 3 > 7" expresses that the value of the expression "2x + 3" is greater than 7 for some values of x.
Inequalities are used to describe a range of values that satisfy a certain condition. The solution to an inequality is a set of values that make the inequality true.
To solve the inequality "5x - 4 > 12 or 12x + 5 < -4", we can start by solving each inequality separately and then combining the solutions to find the final solution.
Solving the first inequality: 5x - 4 > 12Adding 4 to both sides, we get 5x > 16
Dividing both sides by 5, we get x > 3.2
So, the solution to this inequality is x > 3.2
Solving the second inequality: 12x + 5 < -4Subtracting 5 from both sides, we get 12x < -9
Dividing both sides by 12, we get x < -0.75
So, the solution to this inequality is x < -0.75
Final solution: Combining the solutions from both inequalities:
Since "or" is used in the inequality, the solution is the union of the solutions from both inequalities. That is, x is either greater than 3.2 or less than -0.75. So, the final solution is: -0.75 < x < 3.2.
So the solution to the inequality "5x - 4 > 12 or 12x + 5 < -4" is -0.75 < x < 3.2.

What is equation?A mathematical equatiοn is a formula that joins two statements and uses the equal symbol (=) tο indicate equality. A mathematical statement that establishes the equality of twο mathematical expressiοns is known as an equation in algebra. Fοr instance, in the equatiοn 3x + 5 = 14, the equal sign places the variables 3x + 5 and 14 apart.
The relationship between the twο sentences on either side of a letter is described by a mathematical formula. Often, there is οnly one variable, which also serves as the symbοl. for instance, 2x – 4 = 2.
t x = the number of ounces of Sοlution A
y = the number of ounces of Sοlution B
x + y = 180
y = 180 - x
Solving equation -
0.60 + 0.85y = 0.75(180)
0.60 + 0.85y = 135
60x + 85y = 13500
60x + 85(180-x) = 13500
60x + 15300 - 85x = 13500
-25x = -1800
x = 72ounces
y = 180 - 72
y = 108 ounces

Step-by-step explanation:
Use a graphing utility to graph the cost and revenue functions in the same viewing window. Find the sales x necessary to break even (R = C) and the corresponding revenue R obtained by selling x units. (Round to the nearest whole unit.)
Cost Revenue
C = 7.8 √x + 22,000 R = 13.82x
The revenue corresponding to break even condition for selling x units is $4.28.
What is a cost function?An evaluation of the model's accuracy in estimating the link between X and y is done using a cost function. In most cases, this is represented as a difference or distance between the projected value and the actual value. The price element (you may also see this referred to as loss or error.)
To break even (R = C) we have:
7.8 √x + 22,000 = 13.82x
Substitute the value of x = u² thus:
7.8u +22000 = 13.8u²
13.8u² - 7.8u - 22000 = 0
The quadratic formula is given as:
u = -b ± √b² - 4ac / 2a
u = -(-7.8) ± √(-7.8)²- (4)(13.82)(22000) / 2(13.82)
u = 7.8 ± 7.8 / 27.64
u = 7.8 + 7.8 / 27.64
u = 0.56
Back substituting the value of u:
x = u²
x = (0.56)²
x = 0.31
Substituting the value of x is R:
R = 13.82 (0.31)
R = 4.28
Hence, the revenue corresponding to break even condition for selling x units is $4.28.

An assiatant receies a 10% raise, bringing the salary to 47,585. What was the salary before the raise?
Answer:
Step-by-step explanation:
here's a more detailed explanation:
The assistant received a raise of 10%, which means that their salary increased by 10% of the original salary. The new salary after the raise is given as 47,585.
To find the original salary before the raise, we need to reverse the effect of the raise. To do this, we divide the new salary by the factor that represents the increase, which is 1 plus the raise as a decimal.
The raise as a percentage is 10%, which is equivalent to 0.10 as a decimal. Therefore, the factor that represents the increase is 1 + 0.10 = 1.10.
We can now use this factor to find the original salary by dividing the new salary by the factor:
Original salary = New salary / (1 + Raise as a decimal)
Original salary = 47,585 / (1 + 0.10)
Original salary = 47,585 / 1.10
Original salary = 43,259.09
So the salary before the raise was 43,259.09.

5m what is the area of this shape
The area of the given composite shape with two rectangles is 68 m²
What is a rectangle?
There are four right angles on the quadrilateral that forms the rectangle. Every corner or vertex has a right angle where the two sides meet. It differs from a square, which has all of its sides of equal length, in that the opposite sides of the rectangle are equal in length. Two dimensions and flatness combine to make a rectangle.
The figure can be divided into a rectangle with a length of 8m and breadth of 6m and another rectangle of length 5m and breadth = (10-6) = 4m.
To find the area of the whole figure, we first find the areas of small and big rectangles and sum their areas.
Area of small rectangle = length * breadth = 5*4 = 20 m²
Area of big rectangle = length * breadth = 8 * 6 = 48 m²
Therefore the area of the given composite shape with two rectangles is 20+48 = 68 m².
