Answer:
a. For the function:
f(x) = { sin x/3, if x ≤ π
{ x√3/2π, if x > π
I. To find lim f(x) as x approaches π from the negative side, we need to evaluate f(x) for values of x that are slightly less than π. In this case, since sin(x/3) is a continuous function, we can simply evaluate it at x = π:
lim f(x) as x approaches π- = f(π-) = sin(π/3) = √3/2
II. To find lim f(x) as x approaches π from the positive side, we need to evaluate f(x) for values of x that are slightly greater than π. In this case, we can simply evaluate the other part of the piecewise function at x = π:
lim f(x) as x approaches π+ = f(π+) = π√3/2π = √3/2
III. To find lim f(x) as x approaches π, we need to check whether the left-hand and right-hand limits are equal. In this case, since both the left- and right-hand limits exist and are equal, we have:
lim f(x) as x approaches π = √3/2
b. For the function:
f(x) = (x^2 - 36)/√(x^2 - 12x + 36)
I. To find lim f(x) as x approaches 6 from the negative side, we need to evaluate f(x) for values of x that are slightly less than 6. In this case, we can substitute x = 6 - h, where h is a positive number approaching zero, to get:
lim f(x) as x approaches 6- = lim f(6 - h) as h approaches 0
Substituting x = 6 - h into the function, we get:
f(6 - h) = [(6 - h)^2 - 36]/√[(6 - h)^2 - 12(6 - h) + 36]
= [h^2 - 12h]/√[h^2]
Simplifying the numerator and denominator separately, we get:
f(6 - h) = h(h - 12)/|h|
Since h approaches 0 from the positive side, we have:
lim f(6 - h) as h approaches 0+ = lim h(h - 12)/h as h approaches 0+ = lim (h - 12) as h approaches 0+ = -12
II. To find lim f(x) as x approaches 6 from the positive side, we need to evaluate f(x) for values of x that are slightly greater than 6. In this case, we can substitute x = 6 + h, where h is a positive number approaching zero, to get:
lim f(x) as x approaches 6+ = lim f(6 + h) as h approaches 0
Substituting x = 6 + h into the function, we get:
f(6 + h) = [(6 + h)^2 - 36]/√[(6 + h)^2 - 12(6 + h) + 36]
= [h^2 + 12h]/√[h^2]
Simplifying the numerator and denominator separately, we get:
f(6 + h) = h(h + 12)/|h|
Since h approaches 0 from the positive side, we have:
lim f(6 + h) as h approaches 0+ = lim h(h +

7, On the occasion of birthday, Pemba distributed (p² + 29p-96) bottles of sanitizer equally among (p + 32) people of his village. (a) Find the number of bottles of sanitizer received by each people. (b) If x = 8, find the actual number of bottles of sanitizer, number of people, and share of each people
Answer: I got you!
Step-by-step explanation:
(a) To find the number of bottles of sanitizer received by each person, we need to divide the total number of bottles by the number of people. So:
Number of bottles per person = (p² + 29p - 96) ÷ (p + 32)
(b) If we substitute x = 8 into the expression for the number of bottles of sanitizer, we get:
p² + 29p - 96 = x(x + 32)
p² + 29p - 96 = 8(8 + 32)
p² + 29p - 96 = 320
p² + 29p - 416 = 0
We can solve this quadratic equation to get:
p = -32 or p = 13
Since the number of people cannot be negative, we take p = 13. Therefore, the actual number of bottles of sanitizer distributed is:
p² + 29p - 96 = 13² + 29(13) - 96 = 520
The number of people who received the sanitizer is:
p + 32 = 13 + 32 = 45
And the share of each person is:
Number of bottles per person = (p² + 29p - 96) ÷ (p + 32) = 520 ÷ 45 ≈ 11.56
So each person received approximately 11.56 bottles of sanitizer.

What is Statistics?Statistics is the discipline that cοncerns the cοllectiοn, οrganizatiοn, analysis, interpretatiοn, and presentatiοn οf data.
1 Let's start by finding the pattern in the number οf viewers. We knοw that οn the first day, 5 peοple watched the videο. On the next day, the number οf viewers dοubled tο 5 x 2 = 10. On the third day, the number οf viewers dοubled again tο 10 x 2 = 20. We can see that the number οf viewers is dοubling each day, which means we can write the number οf viewers as:
[tex]V = 5 x 2^n[/tex]
where n is the number οf days after the videο was pοsted.
Nοw we want tο find οn which day the number οf viewers will be 640. Sο we can set V equal tο 640 and sοlve fοr n:
[tex]640 = 5 x 2^n[/tex]

Arguing geometrically, find all eigenvectors and eigen-values of the linear transformations in Exercises 15 through 22. In each case, find an eigenbasis if you can, and thus determine whether the given transformation is diagonalizable.
Reflection about a plane V in R3
The eigenvalues of the reflection about a plane in R3 are 1 and -1, with corresponding eigenvectors lying on the plane and perpendicular to the plane, respectively. Therefore, the transformation is diagonalizable with an eigenbasis consisting of these eigenvectors.
Consider a reflection about a plane V in R3. Let's denote this linear transformation by T.
We know that any vector v in R3 can be decomposed uniquely into a sum of two vectors, one in V and one in the orthogonal complement of V. Let's denote these subspaces by V and V⊥, respectively. Then we have:
R3 = V ⊕ V⊥
Since T reflects vectors across the plane V, any vector in V will be fixed by the transformation, while any vector in V⊥ will be flipped across the plane.
Let's consider a vector v in V. Since T fixes v, we have:
T(v) = v
This means that v is an eigenvector of T with eigenvalue 1.
Now let's consider a vector u in V⊥. Since T flips u across the plane V, we have:
T(u) = -u
This means that u is an eigenvector of T with eigenvalue -1.
Since any vector in R3 can be written as a sum of a vector in V and a vector in V⊥, we have shown that every vector in R3 is an eigenvector of T, and the corresponding eigenvalues are 1 and -1.
To find an eigenbasis, we need to find a basis for R3 consisting of eigenvectors of T. We have already shown that every vector in R3 is an eigenvector, so the standard basis {e1, e2, e3} is an eigenbasis. Therefore, T is diagonalizable.
The eigenvalues are λ1 = 1 and λ2 = -1, and the corresponding eigenvectors are {v} and {u}, where v is any nonzero vector in V and u is any nonzero vector in V⊥.

What is GPA?GPA stands for Grade Point Average. It is an academic measure of a student's performance in a course or program of study. It is calculated by dividing the total number of grade points earned by the total number of credit hours taken. A grade point average is typically expressed as a number on a 4.0 scale. A 4.0 GPA is considered to be the highest possible grade point average, while anything below a 2.0 GPA is usually considered to be failing.
This is calculated by adding up the total number of credit hours (10 credit hours) and then multiplying each grade by the respective number of credit hours. A=4.0, B=3.0, C=2.0.
So, you would multiply 4.0 by 3 for FYE 105, 3.0 by 3 for ENG 101, 2.0 by 3 for MAT 150, 2.0 by 3 for BIO 112, and 4.0 by 1 for BIO 113.

What is scalar and vector quantity?Physical quantities with merely magnitude and no direction are called scalar quantities. Scalar values encompass things like mass, volume, temperature, and time. Real numbers, such as positive or negative integers or decimals, are frequently used to represent scalar quantities in mathematics.
In contrast, a vector quantity is a physical quantity that possesses both magnitude and direction. The terms displacement, velocity, force, and acceleration are all examples of vector quantities. Typically, vector values are represented by a number or symbol for the magnitude and an arrow or boldface letter for the direction.
Given that, the temperature went from 28 to -13.
The expression that represent this change are:
Expression 1: -13°F - 28°F
Expression 2: | -13°F - 28°F |

Define the variables that you use to write the system.
pls help i have trouble figuring out what equations im suppose to use to solve.
Answer: 51.25 = 4.75c + 3.25p

1. Since she spent $51.25, we can start our equation with this: 51.25=
2. Since she bought candies and pretzels, we can make 2 new variables, c for candies, and p for pretzels.
3. Since she spent $4.75 per candy, we can add this in to our equation:
51.25 = 4.75c +
4. We can do the same for the pretzels, which she spent $3.25 per piece. Adding this into our equation will leave us with: 51.25 = 4.75c + 3.25p.
5. Now we have to find out what c and p are, given the info that she bought 13 altogether.
6. If we c=6 and p=7, (because they add up to 13) we will get: 51.25!
7. Now we know what c and p are.

The answer of the given question based on the transformation and functions the answers are , (4) a=1 ,b=3 , (5) a=-1 , (b)= 0 , (6) a=-1 ,b=0.
What is Function?In mathematics, function is rule or relationship between two sets of numbers, often represented by formula or a graph, that assigns unique output value for each input value.
More formally, a function is set of ordered pairs (x, y), where each x in the set of inputs is associated with exactly one y in set of outputs. The set of all input values is called domain of the function, and set of all output values is called range of function.
(4) . For the function f(x) = √(x-3) + 4, the transformation can be seen as follows:
a = 1, indicating that there is no vertical stretch or the compression.
b = 3, indicating that the graph is shifted 3 units to the right.
The "+" sign in the function indicates that the graph is shifted upward by 4 units.
(5) . For the function f(x) = -x² + 8, the transformation can be seen as follows:
a = -1, indicating that the graph is reflected vertically.
b = 0, indicating that there is no horizontal shift.
The "+" sign in the function indicates that the graph is shifted upward by 8 units.
(6) . For the function f(x) = -x³ - 5, the transformation can be seen as follows:
a = -1, indicating that the graph is reflected vertically.
b = 0, indicating that there is no horizontal shift.
The "-" sign in the function indicates that the graph is shifted downward by 5 units.

How are linear equations solved?Basic arithmetic operations like addition, subtraction, multiplication, and division are used to isolate the variable on one side of a linear equation and solve it. The objective is to make the equation as simple as possible until the variable can be identified and its value calculated. In order to solve a linear equation, you must first combine like terms to simplify the expressions on both sides of the problem.
Then, you can use inverse operations to get rid of constants and coefficients. The value of the variable can be ascertained by solving for it once it has been isolated. By looking at the coefficients and constants of the equation, it can be established if the equation has no solution or infinite solutions. In various disciplines, such as science, engineering, and finance, linear equations are used to represent connections between variables.

There are two types of trees to plant in the yard type A trees are 36 inches tall and grows 8 inches per year type B are 18 inches tall but grow 10 inches per year when will the trees be the same height
As a result, both varieties of trees will be the same height after 9 years. We can change both equations to a = 9 to verify this: Height of the type A tree is 36 + 8(9) or 36 + 72 inches, whereas the height of the type B tree is 18 + 10(9) or 18 + 90 inches.
What function do height and distance serve in everyday life?Trigonometry includes heights and distances, and it has numerous uses in practical daily life. It utilised to compute height of towers, structures, mountains, etc., and distance between any two objects such celestial bodies others. ,sys,s tos.as to .... and.
Let's use "a" to denote the number of years after planting the trees.
A type A tree will reach the following height after "a" years:
Height of type A tree = 36 + 8a
After "a" years, the height of a type B tree will be:
Height of type B tree = 18 + 10a
We must set the two types of trees' heights equal to one another and solve for "a" to determine when they will reach the same height:
36 + 8a = 18 + 10a
Subtracting 8a from both sides, we get:
36 = 18 + 2a
Subtracting 18 from both sides, we get:
18 = 2a
Dividing both sides by 2, we get:
a = 9
Therefore, after 9 years, both types of trees will be the same height.
To check this, we can substitute a = 9 into both equations:
Height of type A tree = 36 + 8(9) = 36 + 72 = 108 inches
Height of type B tree = 18 + 10(9) = 18 + 90 = 108 inches
