____ regular polygons are symmetrical.
A) Even- sided
B) Odd- sided
C) Rectangular
D) All
Answer:
Step-by-step explanation:
We have to find which type of Regular Polygons are symmetrical.
Regular Polygons are the polygons whose all sides and angles are equal.
For ex:- Equilateral triangle is a regular triangle as its all sides are equal and all angles are equal to 60°.
Square is a regular quadrilateral whose all sides are equal and all angles are equal to 90°.
Option A:
Even-sided regular polygons are the polygons whose no of sides is an even no.
ex, quadrilateral with 4 side, hexagon with 6 sides.
They are symmetrical which no of line of symmetry equal to no of side.
Option B:
Odd-sided regular polygons are the polygons whose no of sides is an Odd no.
ex, Triangle with 3 side, pentagon with 5 sides.
They are symmetrical which only 1 line of symmetry.
Option C:
Rectangular regular polygons are also symmetrical.
Therefore, Option D is correct .i.e., ALL regular polygons are symmetrical.

the table shows the sales of admission tickets to a science museum. A table labeled Science Museum Admission Revenue. It contains a row for Tickets Sold with the amounts 128, 264, 308, 514, 520, 650, 722, and a row for Sales with the amounts 1088, 2244, 2618, 4369, 5525, and 6137. The equation y = 9.75x represents the number of dollars, y, earned by an art museum for selling x tickets. Which statements about the costs of the admission tickets at the museums are true? Select each correct answer. It costs $9.75 per ticket for admission to the art museum. It costs $8.75 per ticket for admission to the science museum. Art museum tickets are more expensive than science museum tickets. Given the same number of ticket sales, the science museum earns more revenue. 1 2 3 4 5
Answer: It costs $9.75 per ticket for admission to the art museum.
Art museum tickets are more expensive than science museum tickets.
Step-by-step explanation:
From the given table of Science Museum Admission Revenue, we can see that the sales amount by selling 128 tickets = $1088
Therefore, the cost of each ticket for science museum =[tex]\frac{1088}{128}=\$8.5[/tex]
∴ It costs $8.5 (not 8.75) per ticket for admission to the science museum.
Also,The equation [tex]y = 9.75x[/tex] represents the number of dollars, y, earned by an art museum for selling x tickets.
At x=1, y=9.75
∴ It costs $9.75 per ticket for admission to the art museum.
Clearly, 9.75>8.5
∴ Art museum tickets are more expensive than science museum tickets.
If the number of ticket sales will be same then art museum will earn more revenue.
Since the price of one ticket to an art museum ($9.75) is higher than the price per ticket for science museum ($8.5), therefore the following statements about the cost at both museums would be true:
Price per ticket for admission to the art museum cost $9.75 (Option A)
Art Museum tickets cost more than that of science (Option C).
Price per ticket to a science museum:
Given the table showing the sales of admission tickets to a science museum:
Thus,
The unit rate/price per ticket sold at the science museum using a pair of values from the table, say, (128, 1088) is: y/x
Thus:
unit rate/price per ticket = [tex]\frac{1088}{128} = 8.5[/tex]That is, a ticket to a science museum costs $8.5.
Price per ticket to an art museum:
The equation, y = 9.75x is given as the equation modelling the situation.
Where x = number of tickets soldy = amount in dollarsThus, this means that the price per ticket to the art museum is: $9.75.
Therefore, since the price of one ticket to an art museum ($9.75) is higher than the price per ticket for science museum ($8.5), therefore the following statements about the cost at both museums would be true:
Price per ticket for admission to the art museum cost $9.75 (Option A)
Art Museum tickets cost more than that of science (Option C).

A circle with radius 5 and a center at (2, 3) was transformed to a circle with radius 10 and a center of (‒1, 4).
Show that the two circles are similar by describing the transformations that would have to be performed.
Answer:
First of all, remember that all circles are similar to each other regardless of how to twist the cartesian plane.
Let the origin in first case(radius 5) be at (0,0) , so if we shift the origin to (2-(-1),3-(4)) = (3,-1) {shifting origin to shift the first circle to second's place}. So, we arrive at a circle of radius 5 and center (-1,4).
Since similarly has no constraints on size comparison increase the radius to 10 units. Thus we arrive at the circle of radius 10 and center (-1,4).
Step-by-step explanation:
First of all, remember that all circles are similar to each other regardless of how to twist the cartesian plane.

The product of 19 and a number , subtracted from the reciprocal of the number cubed
Final answer:
The expression for the product of 19 and a number, subtracted from the reciprocal of the number cubed, is represented as (1/x)³ - 19x. It involves finding the product of 19 and a variable, taking the reciprocal of the variable, cubing it, and then performing the subtraction.
Explanation:
The original question is asking for the expression of a mathematical operation involving a variable and its reciprocal raised to a power. Specifically, the operation is the product of 19 and a number, subtracted from the reciprocal of the number cubed. When constructing this expression, we denote the unknown number as x and perform the following steps:
Identify the product of 19 and x, which is 19x.
Find the reciprocal of x, which is 1/x.
Cube the reciprocal of x to get (1/x)³.
Subtract the product of 19 and x from the cubed reciprocal to get the final expression (1/x)³ - 19x.
This expression represents the mathematical relationship detailed in the question. To simplify or evaluate this expression, additional information about the value of x would be required.

what number must you add to complete the square? x^2+6x=15
Final answer:
To complete the square for the equation [tex]x^2 + 6x = 15,[/tex] you must add 9 to both sides to form the perfect square [tex]trinomial (x + 3)^2 = 24.[/tex]
Explanation:
To complete the square for the equation [tex]x^2 + 6x = 15,[/tex]we need to add a number to both sides of the equation to form a perfect square trinomial on the left side.
Completing the square involves taking half of the linear coefficient (6), squaring it, and adding that value to both sides. Since half of 6 is 3, and 3 squared is 9, we must add 9 to both sides of the equation.
Therefore, our new equation would be[tex]x^2 + 6x + 9 = 15 + 9[/tex] , which simplified to [tex](x + 3)^2 = 24.[/tex]
Sheldon bought a $20 book at a 35% discount. He wrote an expression to find the discounted price. 20−0.35(20) Which expression is equivalent to discounted price Sheldon paid?
A (1−0.35)20
B (1+0.35)20
C (20−0.35)20
D 20+0.35(20)
The equivalent expression to '20 - 0.35(20)', which represents the discounted price Sheldon paid for a book, is '(1 - 0.35)20', or option A.
Explanation:The expression 20−0.35(20) represents the original price of the book Sheldon bought minus the 35% discount. The expression states that Sheldon is taking 35% of $20, which is the book's original price, then subtracting that amount from $20 to find the discounted price he paid.
This operation can be rewritten as multiplication by factoring out the $20 from the expression. Hence, the equivalent expression is (1−0.35)20, representing 65% of the original cost (or the amount Sheldon pays after the discount). Therefore, the answer is A.

If ST=3x, TU=7x, and SU=10, what is ST?
Final answer:
To find the value of ST, we set up the equation 3x + 7x = 10, solve for x, and then calculate ST as 3(1), which gives us ST = 3.
Explanation:
The student is asking to solve for ST, given that ST=3x, TU=7x, and SU=10. This is a segment addition problem, where ST and TU make up the whole segment SU. To solve it, you would first set up the equation ST + TU = SU. Substituting the given values, we get:
3x + 7x = 1010x = 10x = 1After finding the value of x, we substitute it back into the expression for ST:
ST = 3xST = 3(1)ST = 3So, the segment ST is 3 units long.

Which transformations are needed to change the parent cosine function to y=3cos(10(x-pi))
The parent cosine function is transformed [tex]y=3cos(10(x-\pi ))[/tex] by vertically stretching it by a factor of 3 (amplitude), horizontally compressing it by a factor of 10 (frequency), and shifting it to the right by [tex]\pi[/tex] units (horizontal shift or phase shift).
The question asks which transformations are required to alter the parent cosine function to [tex]y=3cos(10(x-\pi ))[/tex]. The transformations involved in this equation are:
Amplitude modification: The coefficient '3' indicates that the amplitude of the cosine function is scaled by a factor of 3.Frequency adjustment: The factor '10' inside the cosine function affects the function's frequency, indicating the function has 10 complete cycles within the interval of [tex]2\pi[/tex] radians. This is a horizontal scaling transformation.Horizontal shift (or phase shift): The subtraction of [tex]\pi[/tex] within the argument of the cosine function translates the function [tex]\pi[/tex] units to the right along the x-axis.No vertical shift is present because there is no addition or subtraction outside the cosine function.
To transform the parent cosine function [tex]\(y = \cos(x)\) to \(y = 3 \cos(10(x-\pi))\)[/tex], apply a vertical stretch by 3, horizontal compression by 1/10, and a right shift by [tex]\(\pi\)[/tex] units.
To transform the parent cosine function[tex]\(y = \cos(x)\)[/tex] to the function [tex]\(y = 3 \cos(10(x-\pi))\)[/tex], we need to apply the following transformations:
1. Amplitude change: Multiply the function by [tex]\(3\)[/tex], which increases the amplitude.
2. Horizontal compression: Multiply the input of the cosine function by [tex]\(10\),[/tex]which compresses the graph horizontally.
3. Phase shift: Shift the graph to the right by [tex]\(\pi\)[/tex]units, indicated by the term [tex]\(x - \pi\).[/tex]
So, the transformations needed are:
- Amplitude change: Vertical stretch by a factor of [tex]\(3\).[/tex]
- Horizontal compression: Compression by a factor of [tex]\(1/10\).[/tex]
- Phase shift: Right shift by [tex]\(\pi\)[/tex] units.
write a linear factorization of the function. f(x) = x4 + 49x2
Answer:
f(x) = [tex]x^2 (x + 7i)(x - 7i)[/tex]
Step-by-step explanation:
The given function is f(x) = [tex]x^4 + 49x^2[/tex]
Here x^2 is a common factor, so we take out and write the remaining term inside the parenthesis.
f(x) = [tex]x^2 (x^2 + 49)[/tex]
f(x) = [tex]x^2 (x^2 - (7i)^2)[/tex] [Here i^2 = -1]
We know that a^2 - b^2 = (a +b)(a-b) using this identity, we get
f(x) = [tex]x^2 (x + 7i)(x - 7i)[/tex]
rewrite the expression as a multiple of a sum of two numbers with no common factor 15+24 _____
To rewrite the expression as a multiple of a sum of two numbers with no common factor, find the prime factorizations of the given numbers and then multiply them together which brings the result as 39.
Explanation:To rewrite the expression as a multiple of a sum of two numbers with no common factor, we need to find two numbers that have no common factors and multiply them together. Let's find the prime factorizations of 15 and 24:
15: 3 × 524: 2 × 2 × 2 × 3Now we can rewrite the expression as:
15 + 24 = (3 × 5) + (2 × 2 × 2 × 3) = 3 × (5 + 8) = 3 × 13 = 39
So, 15 + 24 can be written as a multiple of 3 × 13, which is 39.
