Ao se olhar para a história da Álgebra, desde os primórdios quando o objeto de estudo eram equações algébricas específicas até o estabelecimento de uma área de pesquisa que hoje é essencialmente abstrata (se levarmos em conta muitos dos problemas considerados atualmente pelos pesquisadores), perceberemos um longo caminho de busca de padrões e sedimentação teórica. Essa mesma história nos ensina como aconteceu o difícil estabelecimento dessa área de conhecimento. Houve a necessidade da construção de uma linguagem simbólica apropriada às questões tratadas aliada à consequente emersão de conceitos algébricos cada vez mais abstratos. Só assim a Álgebra se consolidou como área de conhecimento, área essa que é, portanto, fruto de um desenvolvimento histórico e não inata ao ser humano. Dito de outra forma, o conhecimento da Álgebra precisa do meio social para ser aprendido e assimilado pelo indivíduo. De acordo com a nossa estrutura social, esse ensino compete à escola ou, mais especificamente, à disciplina de Matemática. Calcule o produto dos monômios : (4 y²) . (4y)

2). The scale factor of two regular octagons is 52. Find the ratio of their
perimeters and the ratio of their areas, *
Answers
Answer:
Step-by-step explanationBy definition we have that the area of a regular octagon is:
A = 4.83L ^ 2
Where, L is the length of the octagon side.
the similarity ratio = the area ratio.
We have then:
similarity ratio = (50) / (18) = 25/9.
the ratio of the perimeters
A1 = 4.83L1 ^ 2
L1 ^ 2 = A1 / 4.83
L2 ^ 2 = A2 / 4.83
L1 ^ 2 / L2 ^ 2 = A1 / A2 = 25/9
L1 / L2 = 5/3
The perimeter is:
P1 = 8L1
P2 = 8L2
P1 / P2 = 8L1 / 8L2 = L1 / L2 = 5/3
answer:
similarity ratio:
25: 9
the ratio of the perimeters:
5: 3

Step-by-step explanation:
this is about the volume of each size of candle. so the area of the circle , times the height of the candle is the amount of wax needed or it's volume.
area of a circle is = [tex]\pi[/tex][tex]r^{2}[/tex]
then the big candle is [tex]\pi[/tex][tex]2^{2}[/tex] = 12.56637
times 10 for it's height = 125.6637
so that's the big candles volume
then make 20 of those = 2513.27
a small candle is [tex]\pi[/tex][tex]1.5^{2}[/tex] = 7.068583471
and it's 6 cm tall so times 6 = 42.41150082
Now divide the small candle volume into the 20 big ones to see how many small ones can be made
2513.27 / 42.41150082 = 59.259
so just a bit over 59 small candles can be made from 20 big candles

Begin by cross multiplying
Solution
4(3x - 3) = 5(2x - 2) Use the distributive property to remove brackets12x - 12 = 10x - 10 Add 12 to both sides.12x = 10x - 10 + 12 Combine the right12x = 10x + 2 Subtract 10x from both sides12x-10x = 2 Combine the left2x = 2 Divide by 2x = 2/2x = 1Note: the original equation gives you 0/5 = 0/4 which is 0 = 0.
The number of copies made each week by teachers at Lamley High School follows a bell-shaped distribution with a
mean of 550 copies and a standard deviation of 185 copies. Mr. Thomas made 782 copies last week. His Z-score is
1.25. Which of the following statements best interprets this value?
O Mr. Thomas made 125 more copies, on average, than the mean number of copies of teachers at Lamley High
School.
O The number of copies Mr. Thomas made is 1.25 standard deviations less than the mean number of copies of
teachers at Lamley High School.
O The number of copies Mr. Thomas made is 1.25 standard deviations more than the mean number of copies of
teachers at Lamley High School.
O The number of copies Mr. Thomas made is 1.25 standard deviations less than the median number of copies of
teachers at Lamley High School.
O The number of copies Mr. Thomas made is 1.25 standard deviations more than the median number of copies of
teachers at Lamley High School.
Answers
Answer:
3. The number of copies he made is 1.25 standard deviations more than the mean number of copies made by teachers.
Step-by-step explanation:
In statistics, a z-score is measurement that describes a value's relationship to the mean and allows us to compare the value and the mean. It tells us how many standard deviations above or below the population mean.
Mr. Thomas has a z-score of 1.25.
He made 782 copies last week. The statistic this is being compared to is the mean of 550 copies by teachers per week at Lamley High School.
Therefore, the best interpretation is Mr. Thomas made 1.25 standard deviations more than the mean number of copies. The correct answer is choice 3.
Let's make sure the other choices are incorrect.
The first answer is incorrect because a z-score doesn't compare the exact values, but uses the standard deviation to compare. The second answer is incorrect because he made 782 copies, while the mean was 550. He made more copies, plus the z-score is positive. The fourth and fifth answers are incorrect because the z-score doesn't use the median to compare.find the value of x.

[tex]y = \frac{1}{100} \times 10{}^{x} [/tex]
Step-by-step explanation:
Use coordinates (2,1) and 3,10
The exponential equation is
[tex]y = a \times b {}^{x} [/tex]
Plug in the x and y values.xfor both functions of coordinates.
[tex]1 = a \times b {}^{2} [/tex]
[tex]10 = a \times b {}^{3} [/tex]
Divide the equation with the larger exponet by the other equation.
[tex]10 = b[/tex]
Substitute that in for one of the equations.
[tex]10 = a \times 10 {}^{3} [/tex]
Solve for a.
[tex]10 = a \times 1000[/tex]
[tex] \frac{1}{100} = a[/tex]
So our exponetial equation is

This triangle shown has two sides that are the same, both are 6. The value of those two sides is irrelavent, except for the fact that this is an Isosceles triangle and the angle opposite those two sides are equal.
