Answer:
A. A rotation of 72º around the center, point D.
C. A reflection across line b through one vertex, the center d.
E. A reflection across line c, and the midpoint of the opposite side
Step-by-step explanation:
From Euclidean Geometry we get that sum of internal angles inside a polygon equals 360º and there is the following relationship in regular polygons:
[tex]\theta = \frac{360^{\circ}}{n}[/tex] (Eq. 1)
Where:
[tex]\theta[/tex] - Internal angle, measured in sexagesimal degrees.
[tex]n[/tex] - Number of sides, measured in centimeters.
If we know that [tex]n = 5[/tex], then internal angle of regular pentagon is:
[tex]\theta = \frac{360^{\circ}}{5}[/tex]
[tex]\theta = 72^{\circ}[/tex]
In consequence, rotating the regular pentagon 72º around the pentagon carries the figure onto itself due to angular symmetry. (Correct answer: A)
By adding any line passing the center of the regular pentagon (i.e. line cc', line bb'), which is collinear to any vertex and any point of the figure, we guarantee conditions of length symmetry so that reflection carries the figure onto itself. (Correct answers: C, E)

3. 4z^3
4. 3m^4
Answer:
Number 4 has an exponent of 4.
Step-by-step explanation:
The ^ thingy is referring to an exponent. The number after that symbol is the exponent. Therefore, the last answer is the solution to this problem.
The expression which has a base with an exponent of 4 is [tex]3m^4[/tex]
Given two integers a and b, in indices form, we can write;
[tex]a^b[/tex] where:
a is the base
b is the exponent
From the given question, we are to find the expression has a base with an exponent of 4. From the given option;
In p + 4, 4 is not an exponent falsifying option AFor option 2, 4ly, 4 is not an exponent but a baseFor the expression, [tex]4z^3[/tex] 4 is the base, and 3 is the exponent falsifying option C.For the expression, [tex]3m^4[/tex] 3 is the base while 4 is an exponent.

On Saturday, 15,598 people attended a music festival. How does the value represented by the 5 in the hundreds place compare with the value of the 5 in the thousands place? A:The value in the hundreds place is 10 times as much as the value in the thousands place. B:The value in the hundreds place is one-tenth as much as the value in the thousands place. C:The value in the hundreds place is 100 times as much as the value in the thousands place.D: The value in the hundreds place is one one-hundredth as much as the value in the thousands place.
Answer:
B
Step-by-step explanation:
5 in the hundreds place equals 500, but put in the thousands place equals 5,000 and that's 10 times larger than 500. Or as how answer B puts it, 500 is one-tenth as much as 5,000. Either way, it's the same thing

Ray OB divides 2 COA into two angles of equal measure.
True
False
Consider a number line with 40, 60 and 80 marked.
The value 60 is the midpoint of 40 and 80 since (40+80)/2 = 120/2 = 60
If we curved the number line to fit along the round edge of the protractor, then we'll get the diagram you see here.
Ray OB cuts angle COA in two equal pieces (angle COB, angle BOA). This is another way of saying "ray OB bisects angle COA".

Answer:
C
Step-by-step explanation:
x + 9 = 4(x-1)²
x + 9 = 4(x² - 2x + 1) Multiply (x - 1) times (x - 1)
x + 9 = 4x² - 8x + 4
4x² - 9x - 5 = 0 Subtract x + 9 from both sides

Select the locations on the number line to plot the points 10/2 and 9/2
Answer:
Well, 10/2 is actually 5, so the first point would be at 5 on the number line. -9/2 is -4 1/2 as a mixed number. So, the point for -9/2 would be on the right of -5.

Answer:
(4p x 4) x 2 = 16p x 2 = 32p
Step-by-step explanation:
The required simplification is (4p⁴)² = 256p⁸.
What are the rules of exponents?Some of the rules of exponents are as follows,
The product of two exponents having the same power is equal to the power of their base multiplied.
The product of two exponents having the same base is equal to the sum of the powers of different exponents to the same base.
The given expression is as below,
(4p⁴)²
Without using the exponents the given expression can be simplified as follows,
The power to any number simply means that the number will be multiplied to itself as many number of times. this basic rule is used to obtain result as,
(4p⁴)²
= (4p × 4p × 4p × 4p)²
= (16p⁴)²
= 16p⁴ × 16p⁴
= 256 × (p × p × p × p × p × p × p × p)
= 256p⁸

7. SHOW YOUR WORK: Amy's Group can build 1 garage in 8 hours. Bob's
group can build it in 12 hours. How long would it take them if they worked
together? ROUND to the nearest tenth. *
Answer:
It would take 4.8 hours if they worked together
Step-by-step explanation:
The garage can be built by Amy's group in 8 hours and can be built by Bob's group in 12 hours.
Let's find what portion of the garage each group completes in one hour, add their contributions, and find the time to finish the garage working together.
Amy's group completes the job in 8 hours, it means that in 1 hour, they complete 1/8 of the garage.
Bob's group completes the job in 12 hours, meaning they complete 1/12 of the garage in 1 hour.
Now we add both contributions per hour:
[tex]\displaystyle \frac{1}{8}+\frac{1}{12}[/tex]
The LCM of 12 and 8 is 24, thus:
[tex]\displaystyle \frac{1}{8}+\frac{1}{12}=\frac{3+2}{24}=\frac{5}{24}[/tex]
In one hour, they build 5/24 parts of the garage, so the complete job is finished in 24/5=4.8 hours.
It would take 4.8 hours if they worked together
round 67,103 and 1,273 to nearest hundred
Answer:
67100
1300
Step-by-step explanation:
You are rounding to the nearest hundreds place value (will be underlined and bolded). Note the number directly next to the place value (tens place value). If it is the digit 5 or greater, round up. If 4 or less, round down:
67103:
You are rounding to the hundreds place value. The tens place value is a 0. Because 0 is less than 5, round down.
67103 rounded to the nearest hundred is 67100.
1273:
You are rounding to the nearest hundreds place value. The tens place value is a 7. Because 7 is greater than 5, round up.
1273 rounded to the nearest hundred is 1300.
