Answer:
6\(x^{2}\) - 5\(x\) + 1
Step-by-step explanation:
Standard form is: \(ax^{2} +bx+x\)
To reach that you have to distribute:
(2x - 1) (3x - 1)
2x (3x - 1) = 6\(x^{2}\) - 2\(x\)
-1 (3x - 1) = -3\(x\) + 1
Combine like terms:
6\(x^{2}\) - 5\(x\) + 1

Answer:
B = 18°Step-by-step explanation:
To find angle B we use tan
tan ∅ = opposite / adjacent
From the question
AC is the opposite
BC is the side adjacent to angle B
So we have
tan B = AC / BC
tan B = 6/9
tan B = 1/3
B = tan-¹ 1/3

2. Two triangles that are said to be congruent would have corresponding sides and angles. In this case, it has shown that the two sides next to the marked angle are congruent(or the same) along with angle A, equaling angle D. This indicates that the two triangles are congruent.
4. Since all triangle interior angles add up to 180, we can use that information to solve this problem. Angle GEF and angle DEF are supplementary angles; taking this into mind, you can use the equation:
2x+1+25 = 10x+2
1+25-2 = 10x-2x
26-2 = 8x
24 = 8x
3 = x
1. The triangle has been marked, stating that the angles are the same, and if you look closely at the sides, you can see the smaller triangle is dilated by 2 to make the bigger triangle.
Pablo tiene una caja de madera, en la cual ha guardado lo tazo que ha coleccionado. Él deea aber cuánto tiene, cuando lo comenzó a contar vio que, i lo contaba de 7 en 7, de 8 en 8 y de 9 en 9, iempre obraban 5. ¿Cuál e el menor número de tazo que puede tener almacenado?
Por lo tanto, podemos decir que el número mínimo de tazos que Pablo puede tener es 63.
Un Caso de Congruencia ModularEl problema que se plantea es un caso de congruencia modular. La solución más eficiente es usar el Teorema Chino del Resto, que afirma que si a_1, a_2, ..., a_k son números enteros no negativos y n, m_1, m_2, ..., m_k son números enteros mayores a cero que son coprimos entre sí (es decir, el máximo común divisor de m_i y m_j es 1 para todo i y j), entonces existe un único número x (modulo M=m_1m_2...*m_k) que satisface las congruencias:
x ≡ a_1 (mod m_1)
x ≡ a_2 (mod m_2)
...
x ≡ a_k (mod m_k)
En el caso de Pablo, aplicamos el teorema con a_1 = 5, m_1 = 7, a_2 = 5, m_2 = 8 y a_3 = 5, m_3 = 9. Luego, M = 7 * 8 * 9 = 504, y buscamos el menor x positivo tal que x ≡ 5 (mod 7), x ≡ 5 (mod 8) y x ≡ 5 (mod 9).
Para calcular el x que satisface la condición, es necesario encontrar los inversos modular de m_i y aplicar la fórmula del teorema. Sin embargo, en este caso es posible encontrar una solución de manera intuitiva, observando que el menor número positivo que es múltiplo de 7, 8 y 9 es 63. Por lo tanto, podemos decir que el número mínimo de tazos que Pablo puede tener es 63.

BRAINLIEST IF CORRECT: A software development company is voting to elect a president, a secretary, a treasurer, and three directors. If a total of 11 qualified candidates applied for these positions, in how many ways can the positions be filled?
Answer:
498,960 ways
Step-by-step explanation:
The president position can be filled by any one of the 11 qualified candidates. After the president is chosen, the secretary position can be filled by any one of the remaining 10 candidates. Similarly, the treasurer position can be filled by any one of the remaining 9 candidates.
Next, the three director positions can be filled in any order by selecting 3 candidates out of the remaining 8 candidates. The order of the selected candidates does not matter because all 3 directors are equivalent.
Using the multiplication principle of counting, we can multiply the number of choices at each step to find the total number of ways to fill the positions:
Number of ways to choose the president = 11
Number of ways to choose the secretary = 10
Number of ways to choose the treasurer = 9
Number of ways to choose the 3 directors = C(8, 3) = 56 (since order doesn't matter)
Total number of ways to fill the positions = 11 x 10 x 9 x 56 = 498,960
Therefore, there are 498,960 ways to fill the positions in the software development company.
The company can fill the positions in 332,640 ways.
What is Combination?Combination is a way of selecting a subset of objects from a larger set, where the order of selection does not matter.
The company needs to elect a president, a secretary, a treasurer, and three directors.
There are 11 qualified candidates who can run for any of the positions.
The company can fill the positions in the following order:
President (11 candidates to choose from)
Secretary (10 candidates left to choose from)
Treasurer (9 candidates left to choose from)
Director 1 (8 candidates left to choose from)
Director 2 (7 candidates left to choose from)
Director 3 (6 candidates left to choose from)
So, the total number of ways the positions can be filled is:
= 11 × 10 × 9 × 8 × 7 × 6
= 332,640
Therefore, the company can fill the positions in 332,640 ways.

The characteristics of the Stages are given below: Stage A B C Unit processing time(minutes) 1 2 3 Number of machines 1 1 2 Machine availability 90% 100% 100% Process yield at stage 100% 100% 100% Determine the system capacity. Which stage is the bottleneck? What is the utilization of Stage 3.
The system capacity is 2 units per minute, the bottleneck stage is Stage A, and the utilization of Stage 3 is 100%.
A line process has three processing stages with the characteristics given below:
Stage A B C Unit processing time(minutes) 1 2 3 Number of machines 1 1 2 Machine availability 90% 100% 100% Process yield at stage 100% 100% 100%
To determine the system capacity and the bottleneck stage and utilization of Stage 3:
The system capacity is calculated by the product of the processing capacity of each stage:
1 x 1 x 2 = 2 units per minute
The bottleneck stage is the stage with the lowest capacity and it is Stage A. Therefore, Stage A has the lowest capacity and determines the system capacity.The utilization of Stage 3 can be calculated as the processing time per unit divided by the available time per unit:
Process time per unit = 1 + 2 + 3 = 6 minutes per unit
Available time per unit = 90% x 100% x 100% = 0.9 x 1 x 1 = 0.9 minutes per unit
The utilization of Stage 3 is, therefore, (6/0.9) x 100% = 666.67%.
However, utilization cannot be greater than 100%, so the actual utilization of Stage 3 is 100%.
Hence, the system capacity is 2 units per minute, the bottleneck stage is Stage A, and the utilization of Stage 3 is 100%.

A gardener planted a newly sprouted oak tree that was just 3.5 inches tall. The sapling grew 12 inches each year.
Write an equation that shows how the sapling's height in inches, y, depends on the number of years since it was planted, x.
Answer:
y = 12x + 3.5--------------------------------------
Initial height is the y-intercept of the line.
Yearly growth rate is the slope.
So we have:
m = 12, b = 3.5.The equation of the line with these constants is:
y = mx + by = 12x + 3.5The ratio of boys to girls in a class is 5:3. There are 32 students in the class. How many students are boys?
Answer:
5x+3x=8x
8x = 32
x=32/8 = 4
boys are 4 x 5 = 20
girls are 4 x 3 = 12
Step-by-step explanation:
Add the ratios together: 5 + 3 = 8
Divide total students by 8:
32 / 8 = 4
Multiply each ratio by 4 to find the number of each:
Boys = 4 x 5 = 20
Girls = 3 x 4 = 12
There are 20 boys.

Carlos made two identical necklaces each having beads and a pendant. The total cost of the beads and pendants for both necklaces was $12.40. If the beads cost $2.80 for each necklace, how much each does dependent cost?
Answer:
Step-by-step explanation:
So we know that:
Total Cost: $12.40
Beads per Necklace: 2.80
So the first thing we have to do is multiply 2.80 by 2 which equals 5.6 so that's how much of the total cost was for beads.
So now we subtract the amount of money for the beads and the total cost of the necklaces 12.40 - 5.6 = 6.8
So 6.8 was the amount of money that is left for the pendants. Now that we know that we have to divide that by 2 to find out how much money did Carlos spend for each pendant,
6.8÷2= 3.4
So Carlos spent 3 dollars and 4 cents on each pendant.
Simplify the irrational number 128 and estimate it to two decimal places
The approximation of the irrational number, according to the question, is 11.31.
Why are certain numbers irrational?Any actual figure that can't be written as the ratio between two integers, p/q, where both p and q also are integers, is referred to as an irrational number. For instance, it is impossible to represent the integral of 2 as a decimal or a fraction.
The Greeks recognised that a square with sides that are each one measure length has a diagonal which length is irrational. The diagonal's length matches the square root of two according to the Pythagorean Theorem. The denominator of 2 is hence illogical.

what is the decision likely to be for values of χ 2 obt close to 0?
The decision for values of χ^2 obt close to 0 will depend on the level of significance and should be made in the context of the specific hypothesis being tested and the available evidence.
If the obtained value of chi-squared (χ^2 obt) is close to 0, it suggests that the observed data is not significantly different from the expected data. This means that the null hypothesis, which assumes that there is no significant difference between the observed and expected data, is likely to be accepted.
However, the decision whether to accept or reject the null hypothesis also depends on the level of significance (alpha) chosen for the test. If the level of significance is low, even a small difference between the observed and expected data can lead to the rejection of the null hypothesis. On the other hand, if the level of significance is high, a larger difference between the observed and expected data may be required to reject the null hypothesis.
Therefore, the decision for values of χ^2 obt close to 0 will depend on the level of significance and should be made in the context of the specific hypothesis being tested and the available evidence.
