The correct statement about the function represented by the table will be option (D) It is linear function because the y-value increases by an equal difference over equal interval of x-values
The terms "linear function" in mathematics apply to two different but related ideas: A polynomial function of degree zero or one that has a straight line as its graph is referred to as a linear function in calculus and related fields.
Given a table on which there are two column in which one column represents x values while other column represent the y values
We have to find whether the relationship between x value and y value is linear or exponential
From given table let,
y₁ = 34; y₂ = 41; y₃ = 48; y₄ = 55
x₁ = 1; x₂ = 2; x₃ = 3; x₄ = 4
If the relationship between the x value and y value is linear then the difference between two consecutive value of x value and y value would be equal
So y₂-y₁ = y₄-y₃ and x₂-x₁ = x₄-x₃
Putting the value we get difference of y value 7 and x value as 1 since it is same we can say that the relation ship between x value and y value is linear
Hence the correct statement about the function represented by the table will be option (D) It is linear function because the y-value increases by an equal difference over equal interval of x-values

The height of the cylinder will be 5 units based on the information given.
How to calculate the height?The cylinder has a volume of 45π cubic meters and the radius is 3 units.
The height will be calculated thus:
Volume of a cylinder = πr²h
45π = πr²h
45π = π(3²)h
45π = 9πh
h = 45π/9π

The value of p in the equation 2p - 3 = p + 2 Is
Answer:
p = 5
Step-by-step explanation:
Given equation:
2p - 3 = p+2
To Find:
Value of pSoln:
2p - 3 = p + 2
Subtract p from both sides:
=>2p-3−p = p+2-p
=>p-3 = 2
Add 3 to both sides:
=>p−3+3 = 2+3
=>p = 5
Hence,the value of p would be 5.
We can plug the value we got to the original equation to verify:
=> 2p - 3 = p + 2
p = 5=> 2(5) -3 = 5 + 2

4. 6/8, 9/12, 4/16
Step-by-step explanation:
I'm assuming your question is about all 4 problems shown so I'll explain how to solve all of them.
1. The question is asking you to find an equivalent fraction to 1/3. The easiest way to do this is to reduce all of the options given.
To reduce fractions, first determine if the numerator and denominator share any factors. If they do, divide both terms by the shared factors until you no longer get whole numbers.
Step 1: reduce answer choices
6/16 = 3/8 (done by dividing both terms by 2)
4/10 = 2/5 (divide both by 2)
3/8 = 3/8 (fully reduced)
2/5 = 2/5 (fully reduced)
4/12 = 1/3 (divide both by 4)
5/10 = 1/2 (divide both by 5)
1/2 = 1/2 (fully reduced)
3/9 = 1/3 (divide both by 3)
2/6 = 1/3 (divide both by 2)
5/15 = 1/3 (divide both by 5)
3/8 = 3/8 (fully reduced)
3/4 = 3/4 (fully reduced)
2. This question is solved the same way as question 1.
Step 1: reduce answer choices
2/5 = 2/5
6/9 = 2/3
4/8 = 1/2
3/9 = 1/3
8/16 = 1/2
8/10 = 4/5
7/12 = 7/12
6/12 = 1/2
3. This question is solved the same way as questions 1 and 2.
Step 1: reduce answer choices
3/8 = 3/8
2/8 = 1/4
4/9 = 4/9
2/7 = 2/7
4/16 = 1/4
10/14 = 5/7
6/9 = 2/3
3/12 = 1/4
4. This question is solved the same way as questions 1, 2, and 3.
Step 1: reduce answer choices
6/8 = 3/4
4/9 = 4/9
4/6 = 2/3
9/12 = 3/4
10/12 = 5/6
6/9 = 2/3
12/16 = 3/4
7/9 =7/9

1)C
2) C+2
3) C+3
4) C+6
Reason:
The largest sin(x) can get is 1, and the same goes for sin(3x).
Consequently, the largest 2sin(3x) can get is 2.
You can visually verify these claims by graphing each function with a tool like Desmos. Take note of the y coordinate of the highest points. See below.
Therefore, the largest f(x) = 2sin(3x)+C can get is 2+C or C+2

A farmer has 324 feet of fencing to make three identical adjacent rectangular pens, as shown in the picture. What dimensions of each pen will maximize the total enclosed area?
The dimensions of each pen will maximize the total enclosed area are: Length 81 feet; Width 81 feet.
Dimension of each pen
Length = x
Width = y
Area = xy
Perimeter equation is
2(x + y) = 324
x + y = 162
Substituting the perimeter equation
Area = x(162 - x)
Area = -x2 + 162x
If the zeros of the quadratic are 0 and 162, then the median will be where the maximum area occurs.
162/ 2
= 81
Hence, the dimensions are
Length = 81 feet
Width = 162 - 81 = 81 feet
Therefore the dimensions of each pen will maximize the total enclosed area are: Length 81 feet; Width 81 feet.

The first step that we must take before attempting to solve a problem is to understand what the problem is asking us to do and what is given to us to help do it. Looking at the problem statement, it asks for us to determine the area of the figure. In return, we are given the radius of the circle along with the number to use for pi.
Now that we have gathered all of the important information, we can move onto the actual calculations of the problem. Let us use the area of a circle formula to be able to capture the work.
Plug in the values
[tex]A_{circle}=radius^2*\pi[/tex][tex]A_{circle}=(14\ cm)^2*\frac{22}{7}[/tex]Now that we have the expression ready we have several steps that need to be completed in order to have our area ready. Let us start by expanding the exponent.
Expand the exponent
[tex]A_{circle}=(14)^2*(cm)^2*\frac{22}{7}[/tex][tex]A_{circle}=196*cm^2*\frac{22}{7}[/tex][tex]A_{circle}=196\ cm^2*\frac{22}{7}[/tex]Multiply

Answer:
616 square centimeters
Step-by-step explanation:
Area of a circle: πr²
Given:
π = ²²⁄₇r (radius) = 14 cmSubstitute the given values into the formula:
[tex]A=\dfrac{22}{7}\times(14)^2\\\\A= \dfrac{22}{7}\times \dfrac{196}{1}\\\\A= \dfrac{4312}{7}\\\\A = 616[/tex]
