Hello, I am having difficulty with this problem, thanks. Find the smallest numberFind the largest rational numberFind the smallest irrational number
In order to determine which of them is the smallest number, let's convert each number into a decimal number.
[tex]\sqrt[3]{9}=2.080083823\approx2.08[/tex][tex]\sqrt{3}=1.732050808\approx1.73[/tex][tex]\sqrt{\frac{1}{4}}=\frac{1}{2}=0.5[/tex][tex](-5)^{-2}=\frac{1}{(-5)^2}=\frac{1}{25}=0.04[/tex]Upon converting, we can easily that the smallest number is the fourth number which is (-5)^-2.
On the other hand, between the 4 numbers, there are only two rational numbers and these are the 3rd and the 4th number. Between the two, the largest rational number is the 3rd number which is √(1/4) equivalent to 0.5.
Lastly, between the 4 numbers, there are only two irrational numbers and these are the first and the second number. Between the two, the smallest irrational number is √3 which is equivalent to 1.73.
The perimeter of a square is (4x - 44). What is the length of each side?
The perimeter of square is given as,
[tex](4x-44)[/tex]Let length of side is denoted as S.
The formula for the perimeter of square is,
[tex]P=4\times S[/tex]To calculate the side of square , substitute the value of perimeter in the above formula.
[tex](4x-44)=4\times S\text{.}[/tex]Solving the equation we get,
[tex]4(x-11)=4\times S\text{.}[/tex][tex](x-11)=S.[/tex]The length of the square obtained is ,
[tex]S=(x-11).[/tex]Below, the function f(x) =3x-2 f(x)=3x-2 and the function f(x)= 3x+1f(x)=3x+1 are graphed. Compare and contrast the lines. What is similar about the equations and graphs? What is different?
You have the lines associated to the following functions:
f(x) = 3x - 2
f(x) = 3x + 1
The general equation of a line is given by:
y = mx + b
where m is the slope and b the y-intercept.
By comparing the given functions with the general form, you can notice that the slope of the lines are equal (m = 3) and the y-intercept are different, b=-2 and
b = 1.
Due to the slopes are the same you have two parallel lines.
Question 4 (5 points)
In Brock's class of 24 students, 10 students report that math is their favorite class, 25% of the students report that science is
their favorite, and 1/3 prefer reading.. Show your work and/or explain your answer: Which subject is favored by the greatest
number of students? (5 points)
Mathi is favored by the greatest i.e 10 students, using percentage
What is percentage?
A percentage that represents a tenth of a quantity. One percent, denoted by the symbol 1%, is equal to one-hundredth of something; hence, 100 percent denotes the full thing, and 200 percent designates twice the amount specified. A portion per hundred is what the percentage denotes. Percentage refers to one in a hundred. The % sign is used to denote it.
There are 24 students in Brock's class
10 students say math is their favorite class , 25% say that science is their favorite class and 1/3 prefer reading.
Now you have to find out if more students prefer math or science. Well since the information tells you that 10 students prefer math, you need to find out that 25% of students prefer science and 1/3 prefer reading.
For 1st case, math favorite have 10 students,
For 2nd case, 25% of 24 is 24*25/100
=24*1/4
=6
And for 3rd case, who prefer reading is 1/3rd of students which is 24*1/3
=8
So Most students like math.
Hence, Mathi is favored by the greatest i.e 10 students.

from the graph shown in the question,
we could deduce that:
x = -3,
which means x + 3 = y,
we can also deduce that x = 4,
which means that, x - 4 = y
so, the eqaution of the graph could be
y = (x - 2) (x + 3) (x - 4)
since the graph is a cubic graph
therefore the correct option is B
Suppose that f is a one-to-one function, and f^-1 is its inverse. Suppose also that h(x) = 4 and g(x) = x^2 +xsecx. Then which of the following do we NOT know to be true?
Given:
The functions are,
h(x) = 4,
g(x) = x²+xsecx
The objective is to find which of the following is not known to be true.
Let's consider option (A).
[tex]\begin{gathered} (f\circ f^{-1}\circ h)(x)=(f(f^{-1})\circ h)(x) \\ =h(x) \\ =4 \end{gathered}[/tex]Thus, option (A) is true.
Let's consider option (B).
[tex]\begin{gathered} (g\circ h\circ f^{-1})(x)=(g(h(x))f^{-1})(x) \\ =(g(4))f^{-1})(x) \\ =((4^2+4\sec 4)f^{-1})(x) \\ =((16+4\sec 4)f^{-1}(x)) \end{gathered}[/tex]Since, the obtiaed answe doesn't matches with the given options.
Hence, option (B) is not true.
A circle has a diameter of 300m. What is his circumference using pi?
To find the circumference using π = 3.14, we can proceed as follows:
1. The formula to find the circumference of a circle is:
[tex]C=2\pi r\Rightarrow D=2r\Rightarrow C=D\pi[/tex]2. That is, given the diameter, we can use it directly into the answer, since twice the value of the radius is the diameter of the circle:
[tex]C=300m\cdot3.14=942m[/tex]If we find the radius as:
[tex]D=2r\Rightarrow r=\frac{D}{2}=\frac{300m}{2}=150m[/tex]And If we use the next formula:
[tex]C=2\pi r=2\cdot3.14\cdot150m=942m[/tex]As we can see, in both cases, we found that the value for the circumference is equal to 942 meters (if we use π = 3.14).
In summary, the circumference of a circle that has a diameter of 300 meters is equal to 942 meters (C = 942m) (using π = 3.14).

Taylor wants four different pairs of sneakers, but can only afford to buy three of thepairs? How many sets of three pairs of sneakers can she possibly choose?
We have a set of four pairs of sneakers {A; B; C; D} and want to know how many sub-sets of three pairs of sneakers can be made with this.
To calculate that, we just need to have in mind that, for the first pair which Taylor will choose, there are four possibilities. After Taylor chooses the first pair, will be three possibilities for the second pair. And, for the third pair, we will have only the las two possibilities.
So, to gete the total number of sets of three pairs of sneakers that can be made, we just multiply the three correspondent possibilities for each choose: 4*3*2 = 24

8 / 1/3 and 2 / 1/9 what's the generalizations can make about the equations
The generalization about the terms is that one is the cube root of the other
∛(8/9) = 2/3
What is generalizations in mathematics?Generalization can be viewed as a statement that holds true for a broad category of objects or numbers, as the method by which we arrive at a general statement, or as a means of transferring information from one context to another in the mathematics.
The equation represented as 8 / 1/3 and 2 / 1/9
is made an equated to each other and rearranged as follows
8 / 1/3 ⇔ 2 / 1/9
cross multiplying
8 * 1/9 ⇔ 2 * 1/3
8/9 ⇔ 2/3
the equation only holds true when the cube root sign is there then we have
∛(8/9) = 2/3

Step-by-step explanation:
to solve this, you want x alone on one side. To achieve this, you first add 11 on both sides, so you only have the 5x alone.
Second step then is something to get only one x on the left side ;-)
