According to the solving the value of given function h’(5) h’(5) = [2f’(5)g(5)] / g(5)² + f(5) / g(5)²
What exactly is a function?A function is described as a relationship between a group of inputs with one output each. A function is, to put it simply, a relationship between inputs in which each input is connected to exactly one output. Every function has a domain and a codomain, or range. A function is typically represented by the notation f(x), where x represents the input.
According to the given information:To find the value of h’(5), we need to find the derivative of h(x) first. We can use the product rule and the quotient rule to do that:
h(x) = f(x)g(x) + f(x)/g(x)
h’(x) = f’(x)g(x) + f(x)g’(x) + [g(x)f’(x) – f(x)g’(x)] / g(x)² (by the quotient rule)
h’(x) = [f’(x)g(x) + g(x)f’(x)] / g(x)² + [f(x)g’(x) – f(x)g’(x)] / g(x)² + f(x) / g(x)²
h’(x) = [2f’(x)g(x)] / g(x)² + f(x) / g(x)²
Now we can find h’(5) by plugging in x = 5:
h’(5) = [2f’(5)g(5)] / g(5)² + f(5) / g(5)²

Part 2 - Concepts 1) Provide counter-examples to the following statements 1. For any2×2matricesAandB,(AB)2=A2B22. For any2×2matricesA,B, andC, ifAB=AC, thenB=C. 3. For any2×2matrixA, ifA2=A, then eitherA=0orA=I. A counter-example to a "for all" claim consists of a single instance where it fails. This shows that the claim is not universally true. However, it may be true for some cases. For instance, in 2, ifAis invertible, thenAB=ACdoes imply thatB=C. Or in 1 , ifA=B, then(AB)2=A2B2. 2) Decide if each of the following statements is true or false. Justify your conclusion with an explanation or counter-example, as appropriate.
The given statement is true for all matrices A.
1) For any 2x2 matrices A and B, (AB)2 = A2B2 - False. A counter-example to this claim would be if A and B are non-invertible matrices, such as A = [1, 0; 0, 0] and B = [1, 0; 0, 1]. (AB)2 = [1, 0; 0, 0], but A2B2 = [1, 0; 0, 1].
2) For any 2x2 matrices A, B, and C, if AB = AC, then B = C - True. This statement is true, as long as A is an invertible matrix. This can be seen from the properties of matrix multiplication; if AB = AC, then B = A-1AC = C.
3) For any 2x2 matrix A, if A2 = A, then either A = 0 or A = I - False. A counter-example to this claim would be if A = [1, 0; 0, 0], then A2 = A = [1, 0; 0, 0], but A ≠ 0 and A ≠ I.
1) Counter-example:Let the matrices A and B be given by\[A=\begin{pmatrix} 1 & 0 \\ 0 & -1 \end{pmatrix}, B=\begin{pmatrix} 0 & 1 \\ 0 & 0 \end{pmatrix}\].Now,\[(AB)^2=\begin{pmatrix} 0 & 1 \\ 0 & 0 \end{pmatrix}^2=\begin{pmatrix} 0 & 0 \\ 0 & 0 \end{pmatrix}\].and\[A^2B^2=\begin{pmatrix} 1 & 0 \\ 0 & -1 \end{pmatrix}^2\begin{pmatrix} 0 & 1 \\ 0 & 0 \end{pmatrix}^2=\begin{pmatrix} 1 & 0 \\ 0 & 1 \end{pmatrix}\begin{pmatrix} 0 & 0 \\ 0 & 0 \end{pmatrix}=\begin{pmatrix} 0 & 0 \\ 0 & 0 \end{pmatrix}\]Hence\[(AB)^2\ne A^2B^2\]2) Let AB=AC. Then, we need to show that B=C. Let A, B and C be given as follows:\[A=\begin{pmatrix} 1 & 2 \\ 0 & 1 \end{pmatrix}, B=\begin{pmatrix} 3 \\ 4 \end{pmatrix}, C=\begin{pmatrix} 5 \\ 6 \end{pmatrix}\].Now, AB=\[\begin{pmatrix} 1 & 2 \\ 0 & 1 \end{pmatrix}\begin{pmatrix} 3 \\ 4 \end{pmatrix}=\begin{pmatrix} 11 \\ 4 \end{pmatrix}\]and AC=\[\begin{pmatrix} 1 & 2 \\ 0 & 1 \end{pmatrix}\begin{pmatrix} 5 \\ 6 \end{pmatrix}=\begin{pmatrix} 11 \\ 6 \end{pmatrix}\]Thus,\[AB=AC\]But, B=\[\begin{pmatrix} 3 \\ 4 \end{pmatrix}\]and C=\[\begin{pmatrix} 5 \\ 6 \end{pmatrix}\].Therefore,\[B\ne C\]Thus, AB=AC does not imply that B=C.3) True.According to the given statement, \[A^2=A\]Then,\[A^2-A=0\]⇒\[A(A-I)=0\]Either A=0 or A=I. Thus, the given statement is true for all matrices A.

find a formula for the nth term in this arithmetic sequence a1=7, a2=4, a3=1, a4=-2
The nth term of the arithmetic sequence is 10 - 3n.
Arithmetic sequence:An arithmetic sequence is a sequence of numbers in which each term after the first is found by adding a constant value, called the common difference, to the preceding term.
The formula for the nth term (where n is a positive integer) of an arithmetic sequence is:
a[tex]_{n}[/tex] = a₁ + (n-1)dHere we have
a₁ = 7, a₂ = 4, a₃ = 1, a₄ = -2
Common difference d = a₂ - a₁ = 4 - 7 = - 3
By using the formula
nth term of AP = 7 + (n - 1)(-3)
= 7 - 3n + 3
= 10 - 3n
Therefore,
The nth term of the Arithmetic sequence is 10 - 3n.

List the following (and show work if needed): Q1, Median, Q3, Lower Fence, Upper Fence, and Outliers
The median, Q₁, Q₃, lower fence and upper fence of the given data set are 82, 75, 83, 63 and 95.
What is Inter quartile range?
In a range of values, from lowest to highest, the IQR denotes the median 50% of values. Find the median (middle value) of the lower and higher half of the data first, then use that number to calculate the interquartile range (IQR). The first quartile (Q1) and third quartile (Q3) of these values (Q3). What separates Q3 from Q1 is known as the IQR.
Given data set : 72, 81, 82, 83, 83, 85, 100, 54, 75, 81, 83
Firstly, we will arrange the data into ascending order.
we get, 54, 72, 75, 81, 81, 82, 83, 83, 83, 85, 100.
Here, no. of terms is 11
So, Median = (n+1)/2 th = (11+1)/2 = 6th term
So, Median = 82.
Q₁ = (n+1)/4 th term = (11+1)4 th = 3rd term
= 75
Q₃ = 3(n+1)/4 th term = 9th term = 83
Inter-quartile range = Q₃ - Q₁
= 83 - 75 = 8.
Now, Lower fence = Q₁ - 1.5*IQR
= 75 - 1.5× 8
= 75 - 12 = 63
Upper fence = Q₃ + 1.5*IQR
= 83 + 1.5×8
= 83 + 12
= 95.

How many chose purple, green& other?
a. 240 students were surveyed in all. b. 60 students chose blue. c. The number of students who chose purple is 7, green is 10, others is 7 students.
Describe Proportion?In mathematics, a proportion is a statement that two ratios or fractions are equal. A proportion can be expressed as an equation of the form:
a/b = c/d
where a, b, c, and d are numbers, and b and d are not equal to zero. This equation can also be written in the form of a cross product:
ad = bc
This equation means that the product of the numerator of one fraction and the denominator of the other fraction is equal to the product of the denominator of the first fraction and the numerator of the second fraction.
a. If 20% of the students surveyed chose yellow and 48 students chose yellow, we can set up the following proportion to find the total number of students surveyed (let "x" be the total number of students):
20/100 = 48/x
Solving for x, we get:
x = 240
Therefore, 240 students were surveyed in all.
b. 25% of the students surveyed chose blue, so the number of students who chose blue is:
25/100 x 240 = 60
Therefore, 60 students chose blue.
c. We are given that 3% of the students surveyed chose purple, and 4% chose green. To find the number of students who chose purple or green, we can add the two percentages and find the corresponding portion of the total number of students:
3/100 + 4/100 = 7/100
So 7% of the students surveyed chose purple or green. The number of students who chose purple is:
3/100 x 240 = 7.2 (rounded to the nearest whole number, this is 7)
Similarly, the number of students who chose green is:
4/100 x 240 = 9.6 (rounded to the nearest whole number, this is 10)
We are also given that 3% of the students surveyed chose "other". Therefore, the number of students who chose "other" is:
3/100 x 240 = 7.2 (rounded to the nearest whole number, this is 7)
So 7 students chose "other".

If the path of the frisbee is y= –x2 8x 6 and the path of the dog is modeled by y = 2x 6, will the dog catch the frisbee? if so, what are the coordinates of the point or points where they meet?
Yes, dog will catch the frisbee. The coordinates of the point or points where they meet are (0,6) and (6,18). So, option(a) is correct answer for this question.
I have a training your dog to catch a frisbee. The path equation of frisbee is y= –x² + 8x + 6 --(1)
and the path equation of the dog is modeled by
y = 2x + 6 --(2)
We have to check dog catch the frisbee or not and also determine the coordinates. The dog will catch the frisbee, when both equations are intersect to each other. That is intersection point of equation (1) and (2) are the required coordinates. Now, we determine the intersection points between the equation (1) and (2).
Substituting the value of y from equation (2) to equation (1), y = 2x + 6 in y = - x² + 8x + 6
=> 2x + 6 = -x² + 8x + 6
Simplify, x² - 8x + 2x = 6-6
=> x² - 6x = 0
=> x( x - 6) = 0
either x = 0 or x -6 = 0
=> x = 0, x= 6
from equation (1), y = 2(0) + 6 = 6
when x = 6, y = 2(6) + 6 = 18
Hence, required coordinates are (0,6) and (6,18).

Let Π be the plane that contains the point (1,2,3) and is perpendicular to the line that passes through the points A=(3,0,−2) and B=(−1,1,0). (a) Find the distance between the plane Π and the point A. Explain your solution in detail, with diagrams. (b) Find the point on Π that is closest to A.
The point on Π that is closest to A is (3,-2,0).
(a) The distance between the plane Π and the point A is 3. To find this, we need to find the equation of the plane Π. The equation of the plane is given by:
Ax + By + Cz + D = 0
where (A, B, C) is the normal vector to the plane, which is perpendicular to the line that passes through points A and B. Since the normal vector of the plane is perpendicular to the line, the normal vector (A, B, C) is equal to the cross product of the two vectors of the line AB, given by:
A=(3,0,-2), B=(-1,1,0)
A x B = (A2B3-A3B2, A3B1-A1B3, A1B2-A2B1) = (-5,3,3)
Therefore, the equation of the plane Π is:
-5x + 3y + 3z + D = 0
To find D, we need to plug in the coordinates of the point (1,2,3). Therefore,
-5(1) + 3(2) + 3(3) + D = 0
-5 + 6 + 9 + D = 0
D = -20
Therefore, the equation of the plane Π is:
-5x + 3y + 3z - 20 = 0
To find the distance between the plane Π and the point A, we need to calculate the shortest distance between the plane and the point A. We can do this using the distance formula, given by:
d = |Ax + By + Cz + D|/sqrt(A^2 + B^2 + C^2)
Substituting the equation of the plane Π and the coordinates of point A into the distance formula, we get:
d = |-5(3) + 3(0) + 3(-2) - 20|/sqrt(-5^2 + 3^2 + 3^2)
d = |-15 - 20|/sqrt(34)
d = |-35|/sqrt(34)
d = 3
Therefore, the distance between the plane Π and the point A is 3.
(b) The point on Π that is closest to A is (3,-2,0). To find this, we need to solve the system of equations given by:
-5x + 3y + 3z - 20 = 0
x - 3 = 0
y - 0 = 0
z + 2 = 0
Solving this system of equations, we get x = 3, y = -2, and z = 0. Therefore, the point on Π that is closest to A is (3,-2,0).

The circumference of a circle is 17 π π ft. Find its radius, in feet.
By answering the above question, we may state that The circle's radius is radius 8.5 feet as a result.
what is radius?In more modern use, a circle's or sphere's length is equal to its radius, and it is one of the line segments connecting the object's centre and circumference. The phrase is derived from the Roman word circle, which also describes a waggon wheel's spokes. The radius of a circle is the separation of any points on its circumference from its centre. Often, it is denoted by "R" or "r". A line segment with one termination in the centre and one on the circle's perimeter is called a radius. Radius = circular diameter A circle's diameter is the portion that passes through its centre and has ends on the circle.
The formula for calculating a circle's circumference is:
C = 2πr
When r denotes the radius, C denotes the circumference, and denotes a mathematical constant roughly equal to 3.14159.
We are informed that the circle's diameter is 17 feet. We may solve for r by setting this equal to the circumference formula:
17π = 2πr
By multiplying both sides by 2, we obtain:
r = 17π / (2π)
The units are cancelled, leaving:
r = 17 / 2
Examining this expression results in:
r = 8.5 ft

how would the wheel have to be turned for the needle to lean on the outline section?
A. counter clockwise 90°.
B. clockwise 120
C. clockwise 180
D. Counter clockwise, 180
The correct answer is option A, counter clockwise 90°, for the needle to lean on the outline section, the wheel must be turned counter clockwise 90°. Any other turn of the wheel will not result in the needle leaning on the outline section.
What is counter clockwise?Counterclockwise is an adjective used to describe motion or rotation that is in the opposite direction of a clock's hands. For example, when a person swims in a pool, they may swim counterclockwise around the perimeter of the pool. This is the opposite direction of the way a clock's hands move. Counterclockwise rotation is also known as anti-clockwise rotation.
When an object is placed on a flat surface and the wheel is turned, it will rotate in the same direction as the motion of the wheel. If the needle is leaning on the outline section, the wheel must be turned counter clockwise 90°. This is because when the wheel is turned counter clockwise, the needle will be forced to move in the same direction and end up leaning on the outline section.
When the wheel is turned clockwise, the needle will move in the opposite direction and it will not end up leaning on the outline section. Therefore, a clockwise turn of 120° or 180° is not the correct answer. Similarly, turning the wheel counter clockwise by 180° is also not the correct answer. This is because the needle will end up pointing in the same direction it was pointing before the wheel was turned.
In conclusion, for the needle to lean on the outline section, the wheel must be turned counter clockwise 90°. Any other turn of the wheel will not result in the needle leaning on the outline section.

Lisa and Tracy are having lunch. Lisa's lunch costs $6 and Tracy's lunch costs $7. If they leave a 15% tip and pay 5% sales tax, what is the total of the bill?
Answer:
First, we need to calculate the total cost of Lisa's and Tracy's lunches before tax and tip.
Lisa's lunch = $6
Tracy's lunch = $7
Total before tax and tip = $6 + $7 = $13
Now we need to add the 5% sales tax:
$13 x 0.05 = $0.65
Total after tax = $13 + $0.65 = $13.65
Finally, we need to add the 15% tip:
$13.65 x 0.15 = $2.05
Total bill = $13.65 + $2.05 = $15.70
Therefore, the total bill, including tax and tip, is $15.70.
Answer:
Step-by-step explanation:
6 + 7 = 13
Now for the sales tax and tip, we need to add 15 and 5 together which is 20. So now we need to multiply 13 times the decimal equivalent of 20%. So, 0.20 x 13 = 2.6
2.6 + 13 = 15.6
The answer is 15.6
The diameter of a circle is 7 ft. Find its area to the nearest tenth.
Given that diameter of a circle is 7 ft, its area to the nearest tenth is 38.5 square feet.
What is the area of the circle?Area of a circle is the region occupied by the circle in a two-dimensional plane. It can be determined easily using a formula, A = πr2 where r is the radius of the circle.
To find the radius, we can divide the diameter by 2: r = d/2 = 7/2 = 3.5 ft
Now we can plug this into the formula for the area:
A = πr^2
A = π(3.5)^2
A ≈ 38.48
Therefore, rounding to the nearest tenth, the area of the circle is approximately 38.5 square feet.

Step-by-step explanation:
A person places $72000 in an investment account earning an annual rate of 5.1%, compounded continuously. Using the formula V = P e r t V=Pe rt , where V is the value of the account in t years, P is the principal initially invested, e is the base of a natural logarithm, and r is the rate of interest, determine the amount of money, to the nearest cent, in the account after 16 years
The amount of money in account after 16 years will be $162,823.39. The solution has been obtained by using compound interest.
What is compound interest?
Compound interest considers the principal when determining the interest for the subsequent month, in contrast to simple interest, which does not. In algebra, compound interest is typically denoted by the letter C.I.
We are given the following information:
P = $72000
Rate (r) = 5.1% = 0.051
Time (t) = 16 years
Using the formula, we get
⇒V = P[tex]e^{rt}[/tex]
⇒V = (72000) e⁰°⁰⁵¹ˣ¹⁶
⇒V = (72000) e⁰°⁸¹⁶
⇒V = $162,823.39
Hence, the amount of money in account after 16 years will be $162,823.39.

Mr. Barnes rode his bike twenty miles in three hours. Mrs. Barnes rode her bike twenty-four miles in four hours. Mr. Barnes was riding at a
rate than Mrs. Barnes.
In conclusion, Mr. Barnes rode his bike at a rate of 6.67 miles per hour, which was faster than Mrs. Barnes' rate of 6 miles per hour.
How is their speed determined?We must compute the rate or speed that each participant rode in order to determine who rode faster. The rate is calculated by dividing the distance travelled by the time required. The rates for Mr. and Mrs. Barnes will now be determined:
Rate = Distance / Time = 20 Miles / 3 Hours = 6.67 Miles per Hour, Mr. Barnes
Rate = Distance/Time = 24 Miles/4 Hours = 6 Miles Per Hour, Mrs. Barnes
We can observe from comparing the speeds that Mr. Barnes rode more quickly than Mrs. Barnes. Her speed was 6 miles per hour, compared to his 6.67. As a result, we can conclude that Mr. Barnes was riding more quickly than Mrs. Barnes.

Identify the simplest polynomial function having integer coefficients with the given zeros. 0,-3, square root 2.
The polynomial function will be x³ + (3-√2)x² - 3√2x = 0.
What is a polynomial function?
A polynomial function is a function in an equation, such as the quadratic equation, cubic equation, etc., that only uses non-negative integer powers or only positive integer exponents of a variable.
The simplest straightforward and typical mathematical equation is one with polynomial functions. It can be described using a polynomial. The polynomial function is modelled by a polynomial equation. A polynomial is typically written as P. (x). The degree of a polynomial is the largest exponent of the variable P(x). Understanding a polynomial's degree is crucial since it explains how function P(x) behaves as the value of x increases. Polynomial functions only apply to real numbers in their domain (R).
Given : zeros of polynomial = 0, -3 and √2
So, the polynomial function can be found :
= (x-0) (x+3)(x-√2)
= x (x+3) (x-√2)
= (x²+3x) (x-√2)
= x³ -√2x² + 3x² - 3√2x
= x³ + (3-√2)x² - 3√2x

f(x) = 2^x +2: shifts 2 units left
g(x)=
Exponential Functions
Answer:
g(x) = f(x + 2) = 2^(x + 2) + 2
Step-by-step explanation:
To shift the function f(x) = 2^x + 2 two units to the left, we need to replace x with (x + 2) in the equation. This will shift the graph horizontally to the left by two units.
So, the new function g(x) that represents the shifted graph is:
g(x) = f(x + 2) = 2^(x + 2) + 2

An οdd number squared is always an οdd number, and we have prοved it fοr the case οf (2n+1)².
What is integer?An integer is a whοle number that can be either pοsitive, negative, οr zerο. It dοes nοt have a fractiοnal οr decimal cοmpοnent.
Tο prοve that an οdd number squared is an οdd number, we can start by expressing an οdd number as 2n+1, where n is an integer.
Then, we can square this expressiοn tο get:
(2n+1)² = (2n+1)(2n+1)
Expanding the right side οf the equatiοn using the distributive prοperty, we get:
(2n+1)² = 4n² + 2n + 2n + 1
Simplifying the expressiοn by cοmbining like terms, we get:
(2n+1)² = 4n² + 4n + 1
Nοw we can see that the first twο terms, 4n² and 4n, are bοth even since they cοntain a factοr οf 2. Adding twο even numbers always results in an even number.
Therefοre, the sum οf 4n² and 4n is even.
Adding 1 tο an even number results in an οdd number.
Therefοre, we have shοwn that:
(2n+1)² = 4n² + 4n + 1 = (2n² + 2n) + 1 = 2n(n+1) + 1
Since 2n(n+1) is even, the sum οf 2n(n+1) and 1 is οdd.
Hence, an οdd number squared is always an οdd number, and we have prοved it fοr the case οf (2n+1)².
