The required dimension of the longer side of the fencing is 18 ft.
As given in the question, there is an 18-ft fence on one side of a rectangular garden. the gardener has 43 ft of fencing to enclose the other three sides.
What is the perimeter?Perimeter is the measure of the figure on its circumference.
Here,
Total length of the fencing = 18 + 43
The total length of the fencing = 61
Perimeter of rectangle = 2 length + 2 width
61 = 2 * 18 + 2 width
2 width = 61 - 36
2 width = 25
width = 12.5 ft
Thus, the required dimension of the longer side of the fencing is 18 ft.

Two functions are given below: f(x) and h(x). State the axis of symmetry for each function and explain how to find it.
f(x)
f(x) = −4(x − 8)2 + 3
h(x)
graph of negative 1 times the quantity of x minus 3 squared, plus 2
The axes of symmetry of the functions are f(x): x = 8 and h(x): x = 3
How to determine the axis of symmetry for each function?The functions are given as
f(x) = -4(x - 8)^2 + 3
h(x) = -(x - 3)^2 + 2
A quadratic function is represented as
y = a(x - h)^2 + k
Where the equation of the axis of symmetry of the function is
x = h
This means that the axes of symmetry of the functions are
f(x): x = 8
h(x): x = 3
Hence, the axes of symmetry of the functions are f(x): x = 8 and h(x): x = 3

Given: 2q - r = 4p, 2r = q, r = 2p; prove: q = r
give the statement and reason using properties of equality.
Solving the problem as per a linear equation, it can be proved that q = r.
A linear equation is an algebraic equation in the form of y = mx+ b. The highest power of a variable in a linear equation is always 1. Such equations always form a straight line on the graph.
From equation 1 we can write,
2q - r = 4p.................(1)
or, 2q - 4p = r ( side switched ) ................(2)
Now, 2p = r
or, 4p = 2r and we know 2r = q
Hence, we can write 4p = q ...............(3)
If we put equation (3) in (1)
we will get, 2q - q = r
or, q = r
q = r is proved.

Please help --> 0.42b - 8.3 + 9.14b = -5.91 Show your work please!!!
Answer:
0.25
Step-by-step explanation:
group like terms: 0.42b+9.14b-8.3=-5.91
add similar elements: 9.56b-8.3=-5.91
multiply both sides by 100: 956b-830=-591
add 830 to both sides: 956b-830+830=-591+830
simplify: 956b=239
divide each side by 956: you know what that looks like
simplify: b=1/4
convert to decimal: 0.25
Answer:
b = 0.25
Step-by-step explanation:
Given:
[tex]\sf 0.42b - 8.3 + 9.14b = -5.91[/tex]
Collect like terms:
[tex]\implies\sf 0.42b+ 9.14b - 8.3 = -5.91[/tex]
Combine like terms:
[tex]\implies \sf 9.56b - 8.3 = -5.91[/tex]
Add 8.3 to both sides:
[tex]\implies \sf 9.56b - 8.3+8.3 = -5.91+8.3[/tex]
[tex]\implies \sf 9.56b=2.39[/tex]
Multiply both sides by 100:
[tex]\implies \sf 9.56b \times 100=2.39 \times 100[/tex]
[tex]\implies \sf 956b=239[/tex]
Divide both sides by 956:
[tex]\implies \sf \dfrac{956b}{956}=\dfrac{239}{956}[/tex]
[tex]\implies \sf b=\dfrac{239}{956}[/tex]
Write 956 as 4 × 239:
[tex]\implies \sf b=\dfrac{1 \times 239}{4 \times 239}[/tex]
Cancel the common factor 239:
[tex]\implies \sf b=\dfrac{1}{4}[/tex]
[tex]\implies \sf b=0.25[/tex]

What are fractions?A fraction is a portion of a larger whole. The number is expressed in arithmetic as a quotient, which is the numerator divided by the denominator. Both are integers in a simple fraction. A complex fraction contains a fraction in either the numerator or the denominator. There are three major types of fractions in mathematics. Proper fractions, improper fractions, and mixed fractions are the three types. Fractions are terms that have a numerator and a denominator.So, evaluation of 3/8 - 8/11:
First, we will take the LCM of 8 and 11.LCM of 8, 11 = 88Now,
3/8 - 8/11[11(3) - 8(8)]/88(33 - 64)/88-31/88Therefore, the value of fraction 3/8 - 8/11 after the solution is -31/88.

The length of each side is increased by 2 units. Calvin says that would double the perimeter of the rectangle.
Is he correct? If not, state his error.
A.
Calvin is correct.
B. Calvin is incorrect. He should have squared the 2, so the perimeter would be quadrupled (multiplied
by a factor of 4).
C. Calvin is incorrect. He should add 2 to each side not multiply each side by 2.
D. Calvin is incorrect. He should have cubed the 2, so the perimeter would be multiplied by a factor of 8.
First step: Find the old area. What is the formula for area of a rectangle?
Next step: Find the new area by increasing the measurements 2.
Last: Find new area.
Calvin is incorrect. He should add 2 to each side not multiply each side by 2.
The correct answer is an option (C)
For given question,
Let l be the length of the rectangle and w be the width of the rectangle.
Assume that l = 10 units and w = 4 units
The perimeter of the rectangle is,
P = 2(length + width)
So, for above values the perimeter of the rectangle would be,
⇒ P1 = 2×(10 + 4)
⇒ P1 = 28 units
The length of each side is increased by 2 units.
so, l = 12 and w = 6 units
Then the perimeter of the rectangle would be,
P2 = 2(12 + 6)
P2 = 36 units
According to Calvin, if the length of each side of rectangle is increased by 2 units, the perimeter of the rectangle would double.
But from P1 and P2 we can clearly observe that, Calvin is incorrect.
Calvin possibly double the each side of the rectangle instead of increasing by 2 units.
If he double each side then l = 20 and w = 8
The perimeter of the rectangle would be,
P3 = 2(20 + 8)
P3 = 56
From P1 and P3, the perimeter of the rectangle is doubled.
Therefore, Calvin is incorrect. He should add 2 to each side not multiply each side by 2.

No, it is not as a result of all whole numbers are integers, thus there's no number that's not associate degree whole number.
A rational number may be outlined as any number that may be expressed or written within the p/q type, wherever 'p' and 'q' area unit integers and Q could be a non-zero number.The whole numbers area unit the numbers while not fractions and it's a group of positive integers and nil. it's diagrammatical by the image “W” and also the set of numbers area unit . Zero as a full represents nothing or a null worth.These numbers area unit positive integers as well as zero and don't embody aliquot or decimal elements (3/4, 2.2 and 5.3 don't seem to be whole numbers).

1.44 make-up exam: in a class of 20 students, 19 of them took an exam in class and 1 student took a make-up exam the following day. the professor graded the first batch of 19 exams and found an average score of 79 points with a standard deviation of 7.3 points. the student who took the make-up the following day scored 60 points on the exam.
a) Since the new score is less than the average score, it will decrease the average.
What a standard deviation means?The degree of data dispersion from the mean is indicated by the standard deviation. A low standard deviation implies that the data are grouped around the mean, whereas a large standard deviation shows that the data are more dispersed.Think about the following data: 2, 1, 3, 2, 4. The average and the total square of the observations' departures from the mean will be 2.4 and 5.2, respectively. There will be a standard deviation of (5.2/5) = 1.01.Statistics experts have established that measures that are within plus or minus 2 SD of the true value are more accurate than those that fall outside of this range. For data points that frequently fall outside of the 2SD range, the majority of QC programs mandate that remedial action be taken.a) Since the new score is less than the average score, it will decrease the average.
b) Sum of 27 scores = 27*79

Use this method to write each equation in logarithmic form. Show your work.
6⁸=a+1
The equation 6 ⁸ = a + 1 in the logarithm form will be given as log ₆ ( a + 1 ) = 8 .
Logarithms are another form of exponents.
For example, we know that 2 raised to which power is equal to 8,
this is expressed by the exponential form as follows 2³ = 8 is equal to log ₂ 8 = 3
Both equations describe the same relationship between the numbers 2, 3, 8 where 2 is the base and 3 is the exponent
The difference is that while the exponential form isolates the power 8,the logarithmic form isolates 3
So by writing given equation in logarithmic form we get -log₆ ( a + 1 ) = 8.
Therefore, the equation 6 ⁸ = a + 1 in the logarithm form will be given as log ₆ ( a + 1 ) = 8 .

The logarithm is exponentiation's opposite function in mathematics. This means that the exponent to which a fixed number, base b, must be raised in order to produce a given number x, is represented by the logarithm of that number.
Based on the logarithm base, the logarithmic functions are broadly divided into two types. There are common and natural logarithms. Common logarithms are based on the number 10, while natural logarithms are based on the base "e." The power to which a number must be raised in order to obtain another number is known as a logarithm (see Section 3 of this Math Review for more about exponents).
