let ω0, ω1, . . . , ωn−1 denote the n distinct nth roots of unity, so that ωnk = 1 for each k = 0, . . . , n −1. what is the value of the sum ω0 ··· ωn−1? prove your answer.
The sum of the n distinct nth roots of unity is equal to 0, i.e. ω0 + ω1 + ... + ωn-1 = 0.
To prove this:
Consider a complex number z = cos(2π/n) + i sin(2π/n). It is a primitive nth root of unity, i.e.[tex]z^n[/tex] = 1.
Let w = [tex]z^k[/tex] for k = 1, 2, ..., n-1, then w is also a primitive nth root of unity.
So the sum of all the nth roots of unity can be expressed as:
[tex]1 + w + w^2 + ... + w^{(n-1)} = \frac{(1 + w + w^2 + ... + w^{(n-1)}}{z^{(n-1)}} = \frac{(z^n - 1)}{(z - 1) }= 0[/tex]
Hence, the sum of the n distinct nth roots of unity is equal to 0.
A complex number is a number that can be expressed in the form a + bi, where a and b are real numbers, and i is a solution of the equation x2 = −1. It is the combination of a real number and an imaginary number. Complex numbers are used in many areas of mathematics, including algebra, calculus, and number theory.

The volume of a solid generated by rotating a region about the x-axis is an important mathematical concept that can be applied in many real-world situations.
The volume of a solid is a measure of the amount of space that the solid takes up in three-dimensional space.
To find the volume of the solid generated when a region is bounded by an equation and revolved around the x-axis, we use a mathematical formula known as the "method of cylindrical shells."
This method involves slicing the solid into thin cylindrical shells, and then finding the volume of each individual shell. The sum of the volumes of the shells will equal the total volume of the solid.
The formula for the volume of a cylindrical shell is given by

Jacob and Jordan are training for track season. Jacob did 39 sit-ups in 30 seconds. Jordan did 59
sit-ups in 50 seconds. Who will likely do more sit-ups in 2 1/2 minutes? Explain.
Answer: Jacob
Step-by-step explanation:
Jacob = 39 sit-ups/30 seconds
Jordan = 59 sit-ups/50 seconds
2.5 minutes = 150 seconds
[tex]Jacob=\frac{39}{30} =\frac{195}{150}[/tex]
[tex]Jordan=\frac{59}{50}=\frac{177}{150}[/tex]
[tex]\frac{195}{150} > \frac{177}{150}[/tex]
To compare the number of sit-ups Jacob and Jordan can do in 2 1/2 minutes, we need to convert their current rates to the same unit of time. Since 2 1/2 minutes is the same as 150 seconds, we can use unit rates to find the number of sit-ups they can do per second.
Jacob's rate is 39 sit-ups in 30 seconds, so his unit rate is:
39/30 sit-ups per second
Simplifying the fraction, we get:
13/10 sit-ups per second
Jordan's rate is 59 sit-ups in 50 seconds, so his unit rate is:
59/50 sit-ups per second
Multiplying the numerator and denominator by 3, we get:
177/150 sit-ups per second
Now we can use these unit rates to estimate the number of sit-ups Jacob and Jordan can do in 2 1/2 minutes:
Jacob's estimated number of sit-ups = unit rate × time
= (13/10 sit-ups per second) × (150 seconds)
= 195 sit-ups
Jordan's estimated number of sit-ups = unit rate × time
= (177/150 sit-ups per second) × (150 seconds)
= 177 sit-ups
Based on these estimates, Jacob is likely to do more sit-ups in 2 1/2 minutes than Jordan, since he can do approximately 18 more sit-ups (195 - 177).
Therefore, Jacob is likely to do more sit-ups in 2 1/2 minutes than Jordan.

You're looking for the slope of the line that forms the triangle's hypotenuse (the diagonal). The slope formula's "rise" and "run" parameters are the two "legs" of the triangle. Slope is a climb or a run.
What is the Slope Triangle?You may determine a line's slope using a slope triangle, which is a visual aid. Slope refers to how steep something is.
Consider ascending 1,000 feet in the air while piloting a plane. You have advanced (horizontally) 3,000 feet when you are 1,000 feet above the ground. You can calculate how steep your rise was using these two measurements.
The inclination is determined by the height at which the plane rises while moving a predetermined distance forward.
To put it another way, it aids in determining the slope of the line linking the plane's starting point and current location.
Triangle with an airplane slope
You may have seen the following slope formula:
Slope: climb / run
The rise is the triangle's vertical distance. Horizontal distance is measured as the run. For our aircraft, we receive:
Slope is equal to 1,000/3,000 feet, or one-third.
In other words, the plane rises one foot vertically for every three feet it moves across the ground.
The ascension of a plane is steeper if it is 2,000 feet above the earth after moving ahead 3,000 feet. It has advanced further vertically for the same horizontal distance. The triangle's slope is less flat in this instance.
Longer is the triangle's horizontal leg.
Slope is defined as: rise/run = 2,000 ft/3,000 ft = 2/3
1/3 is a smaller climb slope for the first airplane than 2/3 is for the second. More steeply ascending is the second aircraft.

Suppose a shoe factory produce both low grade and high grade shoes. The factory produces at least twice as many low grade as highgrade shoes. The maximum possible production is 500 pairs of shoes. A dealer calls for delivery of at least 100 high garde pairs of shoes per day. Suppose the operation makes a profit of birr 2. 00 per a pair of shoes on high grade shoes and birr 1. 00 per pairs of shoes on low grade shoes. How many pairs of shoes of each type should be produced for maximum profit?
Factory should produce 100 high-grade shoes and 200 low-grade shoes for maximum profit.
Let x be the number of high-grade shoes produced, then the number of low-grade shoes produced is at least 2x. The maximum number of shoes the factory can produce is 500, so we have the following constraints:
x + 2x ≥ 500 (production constraint)
x ≥ 100 (delivery constraint)
x ≥ 0 (non-negative constraint)
The profit for each type of shoe is given as birr 2.00 for high-grade shoes and birr 1.00 for low-grade shoes, so the total profit is:
Profit = 2x * 2.00 + 1.00 * 2x = 4.00x + 2x = 6.00x
The objective is to maximize the profit, subject to the constraints above. So, the feasible solution is x = 100, which means the factory should produce 100 high-grade shoes and 200 low-grade shoes. This is the maximum possible profit of 600 birr.

Step-by-step explanation:
x² = 64 ( take square root of both sides )
x = ± [tex]\sqrt{64}[/tex] = ± 8
solutions are x = 8 and x = - 8 , since
8 × 8 = 64 and - 8 × - 8 = 64

show that the set of all vectors in r4 satisfying the equations is a subspace of r4. find a basis for this subspace.
The set of all vectors in r4 satisfying the equation is,
( x, R , y ) = ( 1 , R , 1/2 ) ( 2 , R , 1 ) ( 3 , R , 3/2 ) ( 4 , R , 2 ) ( 5 , R , 5/2 ) ( 6 , R , 3 ) ( 7 , R , 7/2 ) ( 8 , R , 4 )
A basis for R4 always consists of 4 vectors. (TRUE: Vectors in a basis must be linearly independent AND span.) 4. The union of two subspaces is a subspace.
If S is a subspace of R4, then the zero vector 0=[0000] in R4 must lie in S. 2x+4y+3z+7w+1=0. So 0∉S, and we conclude that S is not subspace of R4.
The space R4 is four-dimensional, and so is the space M of 2 by 2 matrices. Vectors in those spaces are determined by four numbers. The solution space Y is two-dimensional, because second order differential equations have two independent solutions.
The interval of x is known and the relation of x , y is known.
So,
x = 2y ; x = { 1 , 2 , 3 , 4 , 5 , 6 , 7 , 8 }
Then,
1 = 2y , 2 = 2y , 3 = 2y , 4 = 2y , 5 = 2y , 6 = 2y , 7 = 2y , 8 = 2y ,
We can write,
y = { 1/2 , 1 , 3/2 , 2 , 5/2 , 3 , 7/2 , 4 }
Therefore,
The set of all vectors in r4 satisfying the equation is,
( x, R , y ) = ( 1 , R , 1/2 ) ( 2 , R , 1 ) ( 3 , R , 3/2 ) ( 4 , R , 2 ) ( 5 , R , 5/2 ) ( 6 , R , 3 ) ( 7 , R , 7/2 ) ( 8 , R , 4 )

How many times does a human heart beat in 70 years?
The human heartbeats 2,721,600,000 times in 70 years
Let's say that the human heart beats 1 time in 0.8 sec.
Noe, we need to know the number of seconds in 70 years
Number of months in 70 years = 70 x 12 = 840 months
Number of days in 70 years = 840 x 30 = 25,200 days
Number of hours in 70 years = 25,200 x 24 = 604,800 hours
Number of seconds in 70 years = 604,800 x 3600
= 2,177,280,000 seconds
Number of times a heartbeat in 0.8 sec = 1 time
Number of times a heartbeat in 2,177,280,000 seconds = (1/0.8) x 2,177,280,000
= 2,721,600,000 times
≈ 2.7 billion times

Find sn
for the arithmetic series where a1=−20 , n=25 , an=148
The value of Sn for the arithmetic series is, 1,600.
What is Arithmetic sequence?An arithmetic sequence is the sequence of numbers where each consecutive numbers have same difference.
We have to given that;
For the arithmetic series,
⇒ a₁ = - 20
⇒ n = 25
⇒ an = 148
Now, We know that;
The nth partial sum of an arithmetic sequence can be calculated using the first and last terms as follows:
⇒ Sn = n(a₁ + an) / 2
Hence, Substitute all the given values, we get;
⇒ Sn = n(a₁ + an) / 2
⇒ Sn = 25(- 20 + 148) / 2
⇒ Sn = 25 × 128 / 2
⇒ Sn = 1600
Thus, The value of Sn for the arithmetic series = 1,600.

suppose that the universal set ω = {1,2,···,10}and a= {1,2,3}, b= {x∈ω|2 ≤x≤7}, and c= {7,8,9,10}.
Set a is a subset of ω containing the elements 1,2,3. Set b is a subset of ω containing the elements 2,3,4,5,6,7. Finally, set c is a subset of ω containing the elements 7,8,9,10.
The universal set ω is defined as a set containing all elements that are being considered in a particular problem. In this case, ω is composed of the 10 elements 1,2,3,...,10. Set a is then defined as a subset of the universal set ω, meaning that it contains elements from ω. In this example, set a contains the elements 1,2,3. Set b is also defined as a subset of the universal set ω, meaning that it contains elements from ω. In this example, set b contains the elements 2,3,4,5,6,7, as it is composed of all elements of ω that are greater than or equal to 2 and less than or equal to 7. Finally, set c is defined as a subset of the universal set ω, meaning that it contains elements from ω. In this example, set c contains the elements 7,8,9,10, as it is composed of all elements of ω that are greater than or equal to 7.
