The factorised form of 6m + 18 is given by the equation: 6(m + 3).
Given :
Equation - 6m + 18
Solution :
Factorisation is the method of diminishing the bracket of a quadractic condition, rather than growing the bracket and changing over the condition to a item of variables which cannot be decreased assist.
To factorise the equation 6m + 18 we have to follow some steps:
In first step we have to write 18 = [tex]6\times 3[/tex] so the equation becomes:
[tex]\rm = 6m + (6\times3)[/tex] ----- (1)
In second step we have to take 6 common from equation (1):
[tex]\rm=6(m+3)[/tex]
So the factorised form of 6m + 18 is given by the equation: 6(m + 3)

Find an nth degree polynomial function with real coefficients satisfying the given conditions. calculator
To find an nth-degree polynomial function with real coefficients given certain conditions, we can write the polynomial as a product of its linear factors using the given roots.
Explanation:To find an nth-degree polynomial function with real coefficients, we need to use the given conditions. Let's say the conditions include the roots of the polynomial. If we have n distinct real roots, the polynomial will have n factors. So, if the roots are a, b, c, ..., we can write the polynomial as P(x) = (x - a)(x - b)(x - c)...
Example:To find a quadratic polynomial with roots 2 and -3, we can write the polynomial as P(x) = (x - 2)(x - (-3)) = (x - 2)(x + 3) = x² + x - 6.
Similarly, for higher-degree polynomials, we use the same approach. We write the polynomial as a product of its linear factors using the given roots.

At the beginning of the spelling bee there were 60 participants. One-third of the participants were eliminated during the first round. One-fourth of the remaining participants were eliminate during the second round. One-sixth of the remaining participants were eliminated during the third round. How many participants were still cmpeting at the beginning of the fourth round?
By subtracting the eliminated participants in each round from the original number, it is determined that 25 participants were still competing at the beginning of the fourth round.
To find out how many participants were still competing at the beginning of the fourth round of the spelling bee, we need to perform some calculations based on the given percentages of participants eliminated in each round.
In the first round, one-third of the 60 participants were eliminated. This is 60 / 3 = 20 participants eliminated. So, 60 - 20 = 40 participants remained after the first round.In the second round, one-fourth of the remaining participants were eliminated. This is 40 / 4 = 10 participants eliminated. So, 40 - 10 = 30 participants remained after the second round.In the third round, one-sixth of the remaining participants were eliminated. This is 30 / 6 = 5 participants eliminated. So, 30 - 5 = 25 participants remained.Therefore, 25 participants were still competing at the beginning of the fourth round.
Among 320 randomly selected airline travelers, the mean number of hours spent travelling per year is 24 hours and the standard deviation is 2.9. What is the margin of error, assuming a 90% confidence level? Round your answer to the nearest tenth. 0.01
Answer:
The margin of error assuming a 90% confidence level is 0.3
Step-by-step explanation:
Size of the sample: n=320
Mean: m=24
Standard deviation: s=2.9
Confidence interval: 90%
100(1-α)=90
Solving for α: Dividing by 100 both sides of the equation above:
100(1-α)/100=90/100
1-α=0.9
Subtracting 1 both sides of the equation:
1-α-1=0.9-1
-α=-0.1
Multiplying the equation by -1:
(-1)(-α=-0.1)
α=0.1
n= [z(1-α/2) s / E]^2
where E is the margin of error
z(1-α/2)=z(1-0.1/2)=z(1-0.05)=z(0.95)=1.64 (Table standard normal distribution)
z(1-α/2)=1.64
Replacing the known values in the equation above:
320= [(1.64) (2.9) / E]^2
320= (4.756/ E)^2
Solving for E: Square root both sides of the equation:
sqrt(320)=sqrt[ (4.756/ E)^2]
17.88854382=4.756/E
Cross multiplication:
17.88854382 E = 4.756
Dividing both sides of the equation by 17.88854382:
17.88854382 E / 17.88854382 = 4.756 / 17.88854382
E=0.265868486
Rounding tho the nearest tenth:
E=0.3

Carolina is mowing lawns for a summer job. For every mowing job, she charges an initial fee plus $6 for each hour of work. Her total fee for a 4-hour job, for instance, is $ 32.
Carolina's charges can be represented by the linear equation y = 8 + 6x, where x represents hours worked and y represents the total fee charged for the service.
Explanation:The subject this question pertains to is Mathematics, specifically linear equations. Carolina's job can be modelled by a linear equation, where the independent variable is the number of hours worked and the dependent variable is the total fee charged.
In this case, Carolina charges an initial flat fee plus $6 per hour worked. Her total charge for a 4-hour job is $32, which means her initial fee can be deduced by subtracting four times her per-hour fee from the total fee, that is $32 - 4*$6 = $32 - $24 = $8. Therefore, the linear equation that models Carolina's job is y = 8 + 6x, where x is the number of hours worked and y is the total fee charged.
This is similar to the linear equation that represents Svetlana's tutoring job in Example 12.4, where each tutoring session earns her a one-time fee of $25 plus $15 per hour of tutoring, modeled by the equation y = 25 + 15x.

Find the percent of increase from 4.5 inches to 13.5 inches.
Final answer:
To calculate the percent of increase from 4.5 inches to 13.5 inches, subtract the original value from the new value, divide by the original value, and then multiply by 100, resulting in a 200% increase.
Explanation:
To find the percent of increase from one number to another, you can use the formula: (New Value - Original Value) / Original Value × 100%. Applying this to the question, the original value is 4.5 inches, and the new value is 13.5 inches.
Calculate the increase: 13.5 - 4.5 = 9 inches.Divide the increase by the original number: 9 / 4.5 = 2.Convert this to a percentage by multiplying by 100: 2 × 100% = 200%.Therefore, the percent of increase from 4.5 inches to 13.5 inches is 200%.

twice the measure of an angle's complement less 6 is equal to 124 find the measure of the angle
Answer
you work it out the same way the first guy did, except instead of
2 (180-x) - 6 = 124, it's
2(90-x) -6 = 124.
the first guy divided by the supplement instead of the complement.
Step-by-step explanation:
To find the measure of the angle, you can use the equation 2(90 - x) - 6 = 124, where x represents the angle. By solving for x, you can determine that the measure of the angle is 25 degrees.
Explanation:To find the measure of the angle, we can use the information provided in the question. Let's let the measure of the angle be x degrees. The complement of the angle can be found by subtracting the measure of the angle from 90 degrees, since the sum of an angle and its complement is always 90 degrees. Therefore, the complement of the angle is 90 - x degrees.
According to the given equation, twice the measure of the angle's complement less 6 is equal to 124. We can write this as 2(90 - x) - 6 = 124. Now we can solve for x:
2(90 - x) - 6 = 124
180 - 2x - 6 = 124
-2x + 174 = 124
-2x = -50
x = 25
Therefore, the measure of the angle is 25 degrees.
