Which of the following is a factor of 24x^6 - 1029y^3?
The factors of (24x⁶ - 1029y³) are 3, (2x² - 7x), (4x⁴ +14x²y+49y²)
Factors of Polynomials:When a polynomial is factored, its prime factorization is used to break it down into the product of two or more other polynomials. Polynomials may be easily simplified with the use of factoring.
When a polynomial is factored, its factors are expressed as the polynomial's product. Finding the zeros of the polynomial expression or the values of the variables in the supplied expression are both made possible by factoring polynomials.
Here we have
24x⁶ - 1029y³
Take 3 as common
=> 3(8x⁶ - 343y³)
As we know 8 = 2³ and 343 = 7³
=> 3[(2x²)³ - (7y)³]
From the algebraic identities
a³-b³ = (a-b)(a²+ab+b²)Take a = 2x² , b = 7y and apply above formula
=> 3[(2x² - 7x)((2x²)²+(2x²)(7y)+(7y)²)]
=> 3 [ (2x² - 7x) (4x⁴ +14x²y+49y²)]
Therefore,
(24x⁶ - 1029y³) = 3 (2x² - 7x) (4x⁴ +14x²y+49y²)
Therefore,
The factors of (24x⁶ - 1029y³) are 3, (2x² - 7x), (4x⁴ +14x²y+49y²)

The number of sales of cars sold from January to November are 28, 20, 49, 29, 38, 40, 45, 49, 50, 55 and 60. Find the median and modal sales.
The Median and the modal sales is 45 and 49 respectively.
What is a median?A median simply means the middle number when the number are arranged in ascending order. The mode is the number that appears most.
Since the number of sales of cars sold from January to November are 28, 20, 49, 29, 38, 40, 45, 49, 50, 55 and 60, this will be arranged as:
20, 28, 29, 38, 40, 45, 49, 49, 50, 55, 60

You need a 35% alcohol solution. On hand, you have a 300 mL of a 20% alcohol mixture. You also
have 65% alcohol mixture. How much of the 65% mixture will you need to add to obtain the desired
solution?
You will need____
mL of the 65% solution
As per the concept of unitary method, there are 180.8 ml of the 65% mixture will you need to add to obtain the desired solution
Unitary method:
Basically, the way of finding out the solution of a problem by initially finding out the value of a single unit, and then finding out the essential value by multiplying the single unit value.
Given,
You need a 35% alcohol solution. On hand, you have a 300 mL of a 20% alcohol mixture. You also have 65% alcohol mixture.
Here we need to find how much of the 65% mixture will you need to add to obtain the desired solution.
Let us consider x be the amount of the 65% alcohol needed (in milliliters.
Here the amount of the resulting 65% alcohol solution will be is (x+15) milliliters.
So, the amount of the "pure" alcohol in 300 mL of the 20% alcohol solution is written as,
=> 0.20 x 300 mL.
And the amount of the "pure" alcohol in x mL of the 65% alcohol solution is written as,
=> 0.65 * x mL.
Therefore, the total amount of the "pure" alcohol in ingredients is the sum and it can be calculated as,
=> 0.20*300 + 0.65*x mL.
So, it should be equal to the amount of the "pure" alcohol in the mixture, which is written as,
=> 0.35 * (x+15) ml.
Therefore, your "pure alcohol" equation is
=> 0.65* x + 0.20 * 300 = 0.35*(x+15).
When we simplify this one then we get the value of x as,
=> 0.65* x + 0.20 * 300 = 0.35*(x+15).
=> 0.65x + 60 = 0.35x + 5.25
=> 0.3x + 54.25
=> x = 180.8

TYPING Nebi has already typed 250 words. He then starts a timer and finds that he types 150 words in 3 minutes. If Nebi types at a constant rate, write a linear equation to represent the number of words w Nebi types m minutes after starting the timer.
The linear equation that represents the number of words Nebi types per minutes after the timer is started is: w = 50m + 250.
How to Write a Linear Equation?Linear equation can be written in the slope-intercept form as y = kx + b. To write this, find the values of the slope = m, and the y-intercept of starting value = b.
From the equation given, find the unit rate/slope, which is the number of words typed in one minute.
Thus, we have:
Slope/unit rate (m) = 150/3
m = 50 words per minute.
The y-intercept (b) is 250, because it is the initial/starting value.
Let w represent the total number of words, and m represents the minutes after the starting time.
To write the linear equation, substitute k = 50 and b = 250 into w = km + b:
w = 50m + 250

Based on the giving information, what is the measure of the missing length, w?
The measure of the missing length of the triangle is 16 units.
According to the question,
We have the following information:
We have a figure of right-angled triangle where two sides are given.
In order to find the third side of this triangle, we will use the Pythagoras theorem.
So, we have the following expression:
[tex]AC^{2} = AB^{2} + BC^{2}[/tex]
[tex](20)^{2} = AB^{2} + (12)^{2}[/tex]
400 = [tex]AB^{2}[/tex] + 144
Subtracting 144 from both sides of the equation:
[tex]AB^{2}[/tex] = 400-144
[tex]AB^{2}[/tex] = 256
We know that the square root of 256 is 16 or in other words, the square of 16 is 256.
AB = 16 units
Hence, the measure of the missing length of the triangle is 16 units.

The Bay purchases an armchair with MSRP $780 less a trade discount of 30%. The Bay sells the armchair at the MSRP. What is the markup amount?
The markup amount of the purchase is $1114
How to determine the markup amount?From the question, we have the following parameters that can be used in our computation:
Discount = 30%
Selling price = $780
The markup amount is calculated using the following equation
Selling price = Markup amount * (1 - discount)
Make the markup the subject
Markup = Selling price/(1 - discount)
Substitute the known values in the above equation, so, we have the following representation
Markup = 780/(1 - 30%)
Evaluate
Markup = 1114
Hence, the markup is $1114

As per the given angle of elevation, the height of the building is 368.5 ft.
Angle of elevation:
Basically, an angle between the horizontal plane and line of sight from the observer's eye to some object above is known as angle of elevation.
Given,
The angle of elevation to the top of a Building in New York is found to be 2 degrees from the ground at a distance of 2 miles from the base of the building.
Here we need to find the height of the building and round to the tenths.
Here we know that the angle of elevation of the building in New York is written as,
=> θ = 2°
And the distance of observation point from the building is given as,
=> l = 2 miles
Here we know that, 1 miles = 5280 feet
So, the value of l in feet is,
=> l = 2 x 5280
=> l = 10560
Now, it is required to calculate the height of the building. Use the concept of trigonometry to find the height,
So, the height is calculated as,
=> tan θ =h/l
Apply the values on the formula, then we get,
=> tan 2° = h/10560
=> 0.0349 = h/10560
=> h = 0.0349 x 10560
=> h = 368.5 feet.
Therefore, the height of the building is 368.5 ft.
