Jasper claims that there exists a regular polygon for which the measure of each interior angle of the polygon is four times the minimum angle of rotation about its center that carries the polygon onto itself.
For the case where Jasper's claim is true, complete the table by entering the correct information for such a regular polygon.
It is not possible for the measure of each interior angle of a regular polygon to be four times the minimum angle of rotation about its center that carries the polygon onto itself.
What is the interior angle?
The inner of the two angles formed where two sides of a polygon come together. any of the four angles formed in the area between a pair of parallel lines when a third line cuts them.
Jasper's claim is not true. The minimum angle of rotation about the center of a regular polygon that carries the polygon onto itself is called the polygon's "order of rotational symmetry." This angle is always less than or equal to 180 degrees, and it is equal to 360 degrees divided by the number of sides in the polygon.
For example, a regular hexagon has an order of rotational symmetry of 60 degrees (360 degrees / 6 sides), and a regular octagon has an order of rotational symmetry of 45 degrees (360 degrees / 8 sides).
Therefore, if the measure of each interior angle of a regular polygon is four times the minimum angle of rotation about its center that carries the polygon onto itself, then the measure of each interior angle would have to be at least 720 degrees. However, the sum of the interior angles of a regular polygon with n sides is 180(n-2) degrees, which is always less than 720 degrees for any value of n greater than 2.
Therefore, it is not possible for the measure of each interior angle of a regular polygon to be four times the minimum angle of rotation about its center that carries the polygon onto itself.

Answer:
[tex]\huge\boxed{\sf b = -3}[/tex]
Step-by-step explanation:
Given equation:-3(3 + 6b) = 36 - 3b
Distribute
-9 - 18b = 36 - 3b
Add 3b to both sides
-18b + 3b - 9 = 36
-15b - 9 = 36
Add 9 to both sides
-15b = 36 + 9
-15b = 45
Divide -15 to both sides
b = 45/(-15)
b = -3[tex]\rule[225]{225}{2}[/tex]
Answer:
The value of b is -3.
Step-by-step explanation:
The equation is,
→ -3(3 + 6b) = 36 - 3b
Now the value of b will be,
→ -3(3 + 6b) = 36 - 3b
→ -3(3) - 3(6b) = 36 - 3b
→ -9 - 18b = 36 - 3b
→ -18b + 3b = 36 + 9
→ -15b = 45
→ b = -(45/15)
→ [ b = -3 ]
Hence, the value of b is -3.

What is Mean?
A group of two or more numbers is simply averaged mathematically to get the term "mean." There are several ways to calculate the mean for a given collection of numbers, including as the arithmetic mean approach, which utilises the sum of the series' values, and the geometric mean method, which uses the average of a group of products. However, the majority of the time, the results from all of the main approaches to calculating a simple average are roughly the same.
There are two different types of means that can be calculated: the arithmetic mean and the geometric mean.
The arithmetic mean is calculated by adding all of the numbers in a set and dividing by the total number of numbers in the set.
Mean is the ratio of sum of observations to the total number of observation.

What is an equivalent fraction ?
According to equivalent fractions, two or more fractions are considered to be equal if, following simplification, both provide the same fraction. Let's imagine that a/b and c/d are two fractions. If these fractions are simplified to produce comparable fractions, such as e/f, they are then equal to one another.
For instance, if we simplify 5/15, the resulting fraction is the same as 1/3, hence that is the equivalent fraction of 1/3.
The fractions with distinct numerators and denominators but the same value are said to be equivalent fractions. For instance, since 2/4 and 3/6 both equal the 12, they are identical fractions. An element of a whole is a fraction. The same amount of the whole is represented by equivalent fractions.

the manager of a theater wants to know whether the majority of its patrons are adults or children. One day, 5100 tickets were sold and the receipts totaled $29,484. The adult admission is $7.50, and the children's admission is $4.50. How many adult patrons were there
By solving equations, we know that there were 2187 adult partons.
What are equations?A mathematical equation is a formula that uses the equals sign to represent the equality of two expressions.
A function is an equation with a single solution for y for each value of x.
Each input of a particular type receives exactly one output when using a function.
Instead of y, a function is frequently named f(x) or g(x).
When x equals 2, we should determine our function's value because f(2) says to do so.
So, the number of adult patrons was:
Let, a be an adult and c be children.
Total tickets:
a + c = 5200
c = (5200-a)
Total amount:
7.50a + 4.50c = 29961
Replace c in the first equation with (5200-a).
7.5a + 4.5(5200-a) = 29961
7.5a + 23400 - 4.5a = 29961
7.5a - 4.5a = 29961 - 23400
3a = 6561
a = 6561/3
a = 2187
Therefore, by solving equations, we know that there were 2187 adult partons.

remember, the inverse function of y = e^x is x = ln(y).
and the inverse function of y = ln(x) is x = e^y.

28 = 0.48ln(x + 2) + 27
1 = 0.48ln(x + 2)
1/0.48 = ln(x + 2)
e^(1/0.48) = x + 2

I need this really quickly. Thanks to anyone willing to help.
Answer:
3,11
Step-by-step explanation:
Since y = 2x + 5, if you chose (x,y) (3,11):
11 = 2*3 + 5
11 = 6 + 5
11 = 11
Answer:
(3, 11 ) is a solution
Step-by-step explanation:
substitute the x- coordinate of the points into the equation and if the value of y obtained equals the y- coordinate then the point is a solution.
(5, 20 )
y = 2(5) + 5 = 10 + 5 = 15 ≠ 20 ← not a solution
(6, 12 )
y = 2(6) + 5 = 12 + 5 = 17 ≠ 12 ← not a solution
(3, 11 )
y = 2(3) + 5 = 6 + 5 = 11 ← solution
(4, 14 )
y = 2(4) + 5 = 8 + 5 = 13 ≠ 14 ← not a solution
Match each equation on the left with its solution on the right. No answer on the right will be used twice.
The correct match the following is shown below:
2x + 3 (x - 2) = 6 (x + 1) + x → x = -6
2x + 3 (x - 2) = 6 (x - 1) - x → All real numbers
2x + 3 (x - 2) = 6 (x - 1) + x → x = 0
2x + 3 (x - 1) = 6 (x - 1) - x → No solution.
What is equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side. It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Given:
The equation is, 2x + 3 (x - 2) = 6 (x + 1) + x, 2x + 3 (x - 2) = 6 (x - 1) - x, 2x + 3 (x - 2) = 6 (x - 1) + x, and 2x + 3 (x - 1) = 6 (x - 1) - x
Solve the above equations as shown below,
2x + 3 (x - 2) = 6 (x + 1) + x
2x + 3x - 6 = 6x + 6 + x
5x - 6 = 7x + 6
7x - 5x = -6 - 6
x = -6
2x + 3 (x - 2) = 6 (x - 1) - x
2x + 3x - 6 = 6x - 6 - x
5x - 6 = 5x - 6
Infinity solutions,
2x + 3 (x - 2) = 6 (x - 1) + x
2x + 3x - 6 = 6x - 6 + x
5x - 6 = 7x - 6
x = 0
2x + 3 (x - 1) = 6 (x - 1) - x
