The answer is either Option (a) or option(b) or both the options i.e, 120 or √144
What is Integer ?
An integer is a whole number from the set of -ve , non-negative , +ve and 0 numbers.
Let's see how both the option is correct
we know, integers are 0,1, 2, 3, .... or -1, -2 , -3 ......
Means the number which is not in fraction or decimal value or root.
so, by seeing option(a) we can say it's an integer
but in option(b) it's the root so how it is integer
The answer is simple it's perfect square of 12 so √144 = 12 so that means it have the value which is not in fraction. By that we can say that option(b) is also an integer
Now, in option(c) and (d) they are not the perfect square and their root results in decimal values. so we cannot tell them as an integer value.
Hence, the answer is either Option (a) or option(b) or both the options.

Input x Output y3. -56. -49. -3What is a equation
We are to determine the equation of line by interpreting tabulated results between an independent variable ( x ) and a dependent variable ( y ).
A function is usually expressed as follows:
[tex]y\text{ = f ( x )}[/tex]The above notation gives us the output ( y ) which is a function of input variable ( x ). This means that whatever relationship these two variables have the value of output ( y ) is related to the imput variable ( x ).
We are given a table/list of values of output ( y ) corresponding to each value of input variable ( x ) as follows:
Input ( x ) Output ( y )
3 -5
6 -4
9 -3
There are a series of steps that we must take to arrive at the equation that relates two variables.
Step 1: Determine the type of relationship between two variables by intuition
The first step in the process is the hardest of all. We have to critically analyze each input value ( x ) and its corresponding output value ( y ) with successive pair of values.
There are many types of relationships possible ( polynomial order, exponential, logarithmic, trigonometric, radical, etc .. ).
We can conjure up a way by comparing outputs of successive values to determine the type of relationship possible.
So looking at the first value:
[tex]y\text{ = f ( 3 ) = -5}[/tex]The successive value:
[tex]y\text{ = f ( 6 ) = -4}[/tex]The next successive value:
[tex]y\text{ = f ( 9 ) = -3}[/tex]Here if scrutinize between each successive value of input variable ( x ) we see that there is a "3 unit step-up" in each pair of values i.e ( 3 -> 6 -> 9 ).
Next we compare each output values ( y ) for successive pairs. We see that with every step increase of 3 units in ( x ) value there is an increase of ( 1 ) unit in output value i.e ( -5 -> -4 -> -3 ).
Conclusion: Combing the result of above analysis we see that with each 3 step increase in input value ( x ) there is an increase in output value ( y ) by 1 unit.
This gives us the idea that the two variables are linearly related to one another.
Therefore, the type of relationship is:
[tex]\text{straight line }\text{ }[/tex]Step 2: Recall the equation for the type of relationship between two vairbales x and y
Once we have determined the type of relationship between two variables. We will have to resort to our equation bank and pluck out the corresponding equation that expresses a LINEAR relationship i.e equation of a straight line.
The slope-intercept form of a straight line is:
[tex]y\text{ = m}\cdot x\text{ + c}[/tex]Step 3: Determine the complete equation of function by defining the arbitrary constants.
The above equation is valid for all straight lines that express a linear relationship. However, we seek to find a unique straight line for the given set of points.
Every unique straight line equation would have either of the constants different. The constants defined in a striaght line equation are:
[tex]\begin{gathered} m\colon\text{ The slope( gradient ) of the line} \\ c\colon\text{ The y-intercept} \end{gathered}[/tex]To determine these constants we will use the given pairs of coordinates of input and output variables, x and y respectively.
To determine the slope (m) of an equation:
[tex]m\text{ = }\frac{y_2-y_1}{x_2-x_1}[/tex]The above expression relates the change in output value ( y ) with respect to change in input variable ( x ).
To determine the constant ( m ) we will use the conclusion from Step 1:
"3 step increase in input of ( x ) value there is an increase in output value ( y ) by 1 unit."
Therefore,
[tex]m\text{ = }\frac{+1}{+3}\text{ = }\frac{1}{3}[/tex]To determine the value of y-intercept ( c ). We will plug in the value of ( m ) into the general equation of a straight line written in step 2:
[tex]y\text{ = }\frac{1}{3}x\text{ + c}[/tex]Now, we will use any pair of input and output value.
[tex]x\text{ = 3 , y = -5}[/tex]Substitute the pair of values into the derived equation expressed above and solve for constant ( c ):
[tex]\begin{gathered} -5\text{ = }\frac{1}{3}\cdot(3)\text{ + c} \\ -5\text{ = 1 + c} \\ c\text{ = -6} \end{gathered}[/tex]Note: The above step implies that following equation must satisfy each and every data pair of point given to us ( table ). Or each and every value must lie on the line. For that each value must satisfy the equation of line.
Step 4: Write the complete equation of the relationship
Once we have evaluated the values of equation defining constants ( m and c ). We can simply plug in the values into the general equation relationship ( Linear - slope intercept form ) as follows:
[tex]m\text{ = }\frac{1}{3}\text{ , c = -6}[/tex]Therefore, the equation for the set of values given to us is:
[tex]\begin{gathered} \textcolor{#FF7968}{y}\text{\textcolor{#FF7968}{ = }}\textcolor{#FF7968}{\frac{1}{3}\cdot x}\text{\textcolor{#FF7968}{ - 6}} \\ OR \\ y\text{ = }\frac{x\text{ - 18}}{3} \\ \textcolor{#FF7968}{3y}\text{\textcolor{#FF7968}{ = x - 18}} \end{gathered}[/tex]f(x)=[tex]\sqrt{x}[/tex], g(x)=x+9
A: (fg)(x)= ??, Domaine of fg=?
B(gf)(x)=??, Domaine of gf=?
The values are as:
a) f(g(x)) = √(x+ 9)
b) (gf)(x)= √x +9
What is function?The core concept of mathematics' calculus is functions. The unique varieties of relations are the functions. In mathematics, a function is represented as a rule that produces a distinct result for each input x. In mathematics, a function is indicated by a mapping or transformation. Typically, these functions are identified by letters like f, g, and h. The collection of all the values that the function may input while it is defined is known as the domain. The whole set of values that the function's output can produce is referred to as the range. The set of values that might be a function's outputs is known as the co-domain.
Given:
f(x)=√x, g(x)=x+9
a) (fg)(x)=
f(g(x)) = f( x+9)
= √(x+ 9)
Now, domain is all the input values
i.e., x=2, 4, 7
f(g(2)) = √(2+ 9)

= √x +9
Now, domain is all the input values
i.e., x=2, 4, 7
f(g(2)) = √2+ 9

Answer
Option B is correct.
Angle Y = 68º
Explanation
Similar triangles have the same set of angles in them.
All the corresponding angles are equal to each other.
So, if triangle ABC is similar to triangle XYZ
Angle A = Angle X
Angle B = Angle Y
Angle C = Angle Z
The order in which they are named determines the angles that are corresponding to each other.
So, if Angle B = 68º
Angle Y = Angle B = 68º

Elena is making an open top box by cutting squares out of the corners of a piece of paper that is 11 inches wide and 17 in long and then folding up the sides if the side length of a square cut outs RX in in the volume of the box is given by [tex]v(x) = x(11 - 2x)(17 - 2x)[/tex]what is a reasonable domain for V of x?approximately which value of x will give her a box with the greatest volume round to the nearest whole numberfor approximately which values of X is the volume of the Box increasing round to the nearest whole number
The expression for the volume of the box is:
[tex]v(x)=x(11-2x)(17-2x)[/tex]Mathematically, there is no restriction for the values of x, but phisically we know that x is a length and has a positive value, so x>0.
Also, we know that x can not be largest than half of the width, that is the smallest dimension of the piece of paper.
As the width is 11, we then know that x is smaller than 11/2=5.5.
In conclusion, the domain for x is:
[tex]0To calculate the maximum volume for the box we have to derive the volume function and equal to zero:[tex]\begin{gathered} v(x)=x(11-2x)(17-2x) \\ v(x)=x(11\cdot17-11\cdot2x-2x\cdot17+4x^2) \\ v(x)=x(4x^2-56x+187) \\ v(x)=4x^3-56x^2+187x \end{gathered}[/tex][tex]\begin{gathered} \frac{dv}{dx}=4(3x^2)-56(2x)+187(1)=0 \\ 12x^2-112x+187=0 \\ x=\frac{-(-112)\pm\sqrt[]{(-112)^2-4\cdot12\cdot187}}{2\cdot12} \\ x=\frac{112\pm\sqrt[]{12544-8976}}{24} \\ x=\frac{112\pm\sqrt[]{3568}}{24} \\ x=\frac{112}{24}\pm\frac{59.73}{24} \\ x=4.67\pm2.49 \\ x_1=4.67-2.49=2.18\approx2 \\ x_2=4.67+2.49=7.16\approx7 \end{gathered}[/tex]The solutions are x=2 and x=7 approximately.
Because of our domain definition, we know that x=7 is not a valid solution, so the value of x that maximizes the volume is x=2.
The volume for x=0 is 0. Then, it will increase its value until x=2, where it reaches the maximum volume. From x=2 to x=5.5, the volume decrease until reaching v=0 at x=6.5.
Answer:
Domain: 0
Value of x that maximizes the volume: x=2.
From x=0 to x=2 the volume of the box increases.
Find in the exact simplified form of an exact expression for the sum of the first n terms of the following series 1+11+111+1111+11111+.... Binary notation is used to represent numbers on a computer. For example, the number 1111 in base two represents 1(2)^3 + 1(2)^2 +1(2)^1+1, or 15 in base ten. (i) Why is the sum above an example of a geometric series? (ii) Which number in base ten is represented by 11 111 111 111 111 111 111 in base two? Explain your reasoning.
Step-by-step explanation:
so, I understand, the given series is written in binary form.
a1 = 1 = 1×2⁰ = 1
a2 = 11 = 1×2¹ + 1× 2⁰ = 3
a3 = 111 = 1×2² + 1×2¹ + 1×2⁰ = 7
a4 = 1111 = 1×2³ + 1×2² + 1×2¹ + 1×2⁰ = 15
a5 = 11111 = 1×2⁴ + 1×2³ + 1×2² + 1×2¹ + 1×2⁰ = 31
...
we see, that
an = 2×(an-1) + 1
a1 = 1
a2 = 2×a1 + 1
a3 = 2×a2 + 1 = 2×(2×a1 + 1) + 1 = 4×a1 + 2 + 1
a4 = 2×a3 + 1 = 2×(2×a2 + 1) = 2×(2×(2×a1 + 1) + 1) + 1 =
= 8×a1 + 2×2 + 2 + 1 = 8×a1 + 7
...
an = (2^(n-1))×a1 + an-1
because
an = 2×(an-1) + 1,
an-1 = (2^(n-1))×a1 - 1
therefore,
an = 2×(2^(n-1))×a1 - 1 = (2^n)×a1 - 1
the sequence of the sums of the first n elements
s1 = a1 = 1
s2 = a1 + a2 = 1 + 3 = 4
s3 = a1 + a2 + a3 = 7 + 3 + 1 = 11
s4 = a1 + a2 + a3 + a4 = 15 + 7 + 3 + 1 = 26
...
(i)
it is NOT a geometric sequence.
for a geometric sequence
an/an-1 = r, and r must be a constant ratio for any n.
but
7/3 = 2.333333...
15/7 = 2.142857143...
these are different, so, the sequence itself is not geometric.
neither is the sequence of the sums of the series. because
11/4 = 2.75
26/11 = 2.363636363...
are different.
1, 2, 4, 8, 16, 32, ... is a geometric sequence (constant r = 2).
but not
1, 3, 7, 15, 31, ...
(ii)
11 111 111 111 111 111 111 in base 2.
the utmost right position is the 2⁰ position. every position further to the left multiples the position value by 2. it is the same process as for numbers in base 10 (just there every position value is multiplied by 10).
we have 6×3 + 2×1 positions = 20 positions.
so, the position values go from 2⁰ to 2¹⁹.
as per the formula for "an" up there, we get
a20 = (2²⁰)×a1 - 1 = 1,048,576 - 1 = 1,048,575

The mathematics section of a standardized college entrance exam had a mean of and an SD of for a recent year. Assume these are well modeled by a Normal distribution.
Normal distributions are crucial to statistics because they are widely used in the natural and social sciences to represent real-valued random variables whose distributions are unknown.
Normal distribution is a type of continuous probability distribution for a random variable with a real value.
They are important in part because of the central limit theorem. This claim asserts that, in some cases, the mean of many samples (observations) of a random variable with finite mean and variance is itself a random variable, whose distribution tends to converge to a normal distribution as the number of samples increases. Because of this, the distributions of physical quantities, such as measurement errors, which are assumed to represent the sum of multiple distinct processes, are usually close to normal. It may also be referred to as a Laplace-Gauss, Gaussian, or Gaussian distribution.[tex]{\displaystyle f(x)={\frac {1}{\sigma {\sqrt {2\pi }}}}e^{-{\frac {1}{2}}\left({\frac {x-\mu }{\sigma }}\right)^{2}}}[/tex]Another name for a normal distribution is a bell curve.The Cauchy, Student's t, and logistic distributions, among many others, have a bell-shaped structure.The univariate probability distribution is generalized for vectors in the multivariate normal distribution and for matrices in the matrix normal distribution.Hence we can use the normal distribution to find the mean and standard deviation of a data set.

Evaluate the expression for the given variable.9 - k ÷ 3/4 k=2/3
We are given the following expression:
[tex]9-k\div\frac{3}{4}[/tex]We are also given that k is equal to 2/3. So, we can substitute that into the expression:
[tex]9-\frac{2}{3}\div\frac{3}{4}[/tex]Due to order of operations, we have to do the division first, and then do the subtraction. To do division with fractions, we keep the first fraction the same and take the reciprocal of the second fraction. Then, we can multiply the two fractions. Let's do that:
[tex]9-(\frac{2}{3}\div\frac{3}{4})=9-(\frac{2}{3}*\frac{4}{3})=9-\frac{8}{9}[/tex]Now, we can do the subtraction:
[tex]9-\frac{8}{9}=\frac{81}{9}-\frac{8}{9}=\frac{73}{9}[/tex]Therefore, our answer is 73/9

Angles are given below.
Define angles.When two straight lines or rays intersect at a single endpoint, an angle is created. The vertex of an angle is the location where two points come together. The Latin word "angulus ," which means "corner," is where the term "angle" originates. When a transversal connects two coplanar lines, alternate interior angles are created. They are located on the transverse sides of the parallel lines, but on the inner side of the parallel lines. At two different locations, the transversal passes through the two lines that are coplanar.
Given,
∠6 and ∠7 = Vertical angles
∠2 and ∠8 = Same side exterior angles
∠1 and ∠5 = Corresponding angles
∠3 and ∠6 = Adjacent angles
∠2 and ∠7 = Alternate exterior angles
∠4 and ∠6 = Same side interior angles
∠1 and ∠2 = Linear pair

Find the inverse of each function:
b. g(x)= √x
The inverse of the functions given as y = 5(x-2) and f^-1(x) = x²
Inverse of a functionA function's inverse function reverses the action of a function, or f.
a) From the given table, we can use the coordinate points (-5, 1) and (0, 2)
The standard linear equation is y = mx + b
m = 2-1/0-(-5)
m = 1/5
Since the y-intercept is (0, 2), hence the required function is y = 1/5 x + 2.
y = 1/5x + 2
x = 1/5 y + 2
1/5 y = x - 2
y = 5(x-2)
b) For the function g(x) = √x
y = √x
x = √y
y = x²
f^-1(x) = x²
This gives the inverse of the function.

The graph shows the mass of the bucket containing liquid depends on the volume of liquid in the bucket. Use the graph to find the range of the function.
The graph shows that the range of the function is 0.9 ≤ M ≤ ∞.
Linear FunctionA linear function can be represented by a line. The standard form for this equation is: y=mx+b , for example, y=5x+8.
All functions present their domain and range. The domain of a function is the set of input values for which the function is real and defined. In the other words, when you define the domain, you are indicating for which values x the function is real and defined. While the domain is related to the values of x, the range is related to the possible values of y that the function can have.
From the graph it is possible to see that: the function is a linear function, the values of the coordinate x are represented by the volume (liters) while the values of the coordinate y are represented by the mass (kg).
The question asks for the range of the function. Therefore, you should indicate the possible values of y that the function can have.
For this, you should analyze the axis-y. See that for x=0, the graph shows y =0.9. Therefore, the function starts for values of y >= 0.9 kg. It is possible to verify that when the volume increases, the mass also increases. With this information, you can find that the range is 0.9 ≤ M ≤ ∞.

[tex]undefined[/tex]If f (x) = x
2 − 2 x , g (x) = x − 2
1) prove that : f(2) = g(2)
2) If g (K) = 7 , find : the value of k
The value of k is 9 for the function g.
To solve this problem we should have a brief concept of algebraic functions.
To solve this problem we have to follow a few steps.
Here f is a function of x and the relation with the function denotes as x²-2x. Also, g is a function of x and the relation with the function denotes as x− 2.
If we put, x = 2 on f(x) = x²-2x. We can write, f(2) = 2²-2.2 = 4 - 4 = 0.
If we put, x = 2 on g (x) = x − 2. We can write, g(2) = x− 2= 2- 2 = 0.
Hence, we can conclude that f(2) = g(2) = 0. ( proved)
Here, g(k) = 7. So, x = k in this relation.
We have to put x= k on g(x) = x− 2 ; now we can write, g (k) = k− 2.
g (k) = k− 2 = 7 as per the question. Therefore k = 7 + 2 = 9
The value of k is 9.
