Answer:
[tex]-32x^5+320x^4-1280x^3+2560x^2-2560x+1024[/tex]
Step-by-step explanation:
We must expand [tex](-2x+4)^5[/tex] using the Binomial Theorem.
To do so, we need Pascal's Triangle. Seeing that the exponent is 5, we look at the 5 + 1 = 6th row of Pascal's Triangle. The numbers here are:
1, 5, 10, 10, 5, 1
These will be the numbers to multiply all the distinct terms in the expansion by.
Remember that when expanding this out, we always start by taking the first term (-2x here) to the nth power (here, it's 5th power) and multiplying that by the second term (4 here) to the 0th power:
(-2x)^5 * 4^0 = -32x^5 * 1 = -32x^5
Since this is our first term, we multiply it by the first Pascal number from above: 1. Then, we simply get -32x^5 as our final first term of the expansion.
We repeat this process, each time lowering the first power by 1 and increasing the second power by 2.
2nd term:
(-2x)^4 * 4^1 = 16x^4 * 4 = 64x^4
Multiply by 5:
64x^4 * 5 = 320x^4
3rd term:
(-2x)^3 * 4^2 = -8x^3 * 16 = -128x^3
Multiply by 10:
-128x^3 * 10 = -1280x^3
4th term:
(-2x)^2 * 4^3 = 4x^2 * 64 = 256x^2
Multiply by 10:
256x^2 * 10 = 2560x^2
5th term:
(-2x)^1 * 4^4 = -2x * 256 = -512x
Multiply by 5:
-512x * 5 = -2560x
6th term:
(-2x)^0 * 4^5 = 1 * 1024 = 1024
Multiply by 1:
1024 * 1 = 1024
Hence, our expansion is:
[tex]-32x^5+320x^4-1280x^3+2560x^2-2560x+1024[/tex]
The system of equations can be solved using linear combination to eliminate one of the variables.
2x − y = −4 → 10x − 5y = −20
3x + 5y = 59 → 3x + 5y = 59
13x = 39
Which equation can replace 3x + 5y = 59 in the original system and still produce the same solution?
2x – y = –4
10x – 5y = –20
7x = 39
13x = 39

Answer:
32.
Step-by-step explanation:
The first 32 have buttons but NO zips.
Then 35 have NEITHER buttons OR zips.
Then 32 have ZIPs, but no buttons.
The question only asks for zips. The other bag is unaccounted for.

A company is interested in learning if employees are satisfied with their jobs. To find out the company hires an independent market research
company to conduct a survey. Every survey filled out by an employee is anonymous. Which of the following statements is correct?
A This method of sampling is biased.
B This method of sampling is unbiased.
C This method of sampling is neither biased nor unbiased. D This method of sampling can be considered both biased and unbiased.
The statement (B) is correct because it is anonymous, it does not focus on a specific ethnicity, gender, or other factor.
What is a survey?A survey is a means of gathering information from a sample of people using pertinent questions with the goal of understanding populations as a whole.
We have:
A company is interested in learning if employees are satisfied with their jobs.
Every survey that an employee fills out is completely anonymous.
The statement (B) this method of sampling is unbiased because it is anonymous, it does not focus on a specific ethnicity, gender, or other factor.
Thus, the statement (B) is correct because it is anonymous, it does not focus on a specific ethnicity, gender, or other factor.

Find the area of a regular polygon with 9 sides that has a perimeter of 135 inches and an apothem of 6 inches
Answer:
The area of regular polygon with 9 sides is 405 square inches.
Step-by-step explanation:
Given
Perimeter of Polygon = P = 135 inches
Apothem = a = 6 inches
We know that the sides of regular polygon are equal. Let s be the side of the polygon then
[tex]P = 9*s\\135 = 9*s\\s = \frac{135}{9}\\s = 15\ inches[/tex]
Now the formula for area of polygon when apothem, sides and number of sides is known:
[tex]A = \frac{a*n*s}{2}\\A = \frac{6*9*15}{2}\\A=\frac{810}{2}\\A = 405\ in^2[/tex]
Also the formula can be written as:
[tex]A = \frac{1}{2}P*a[/tex]
Hence,
The area of regular polygon with 9 sides is 405 square inches.

Answer:
The student scores 20 pts
Step-by-step explanation:
A student answers 10 Q's correct, this earns the student 30 points (3 x 10)
The other 5 Q's are presumably wrong since they did answer the question
If every question wrong loses 2 pts then the student lost 10 points from wrong answers (2x5) =10
Take the total amount of secured points and subtract the points for questions that the student got wrong
30 pts - 10 pts = 20 pts
Answer:
20
Step-by-step explanation:
15 questions answered
10 are correct so they get 30 or 3*10
5 are incorrect so the get a -10 or -2*5
Total score is 30-10 or 20

A giant tortoise can travel 0.14 miles in 1 hours .At this rate ,how long would it take to travel 2 miles ?
Answer:
about 14.3 hours
Step-by-step explanation:
The relation between time, speed, and distance can be written any of three ways:
time = distance/speeddistance = speed×timespeed = distance/time__
Here, the question asks for the travel time, so the relevant relation is the first one. Filling in the given values, we have ...
time = (2 mi)/(0.14 mi/h) ≈ 14.29 h
It would take about 14.3 hours to travel 2 miles.

9514 1404 393
Answer:
(x, y) = (2, 1)
Step-by-step explanation:
Use the second equation to write an expression for x:
x = 1 +y
Substitute that into the first equation:
(1 +y) +4y = 6
5y = 5 . . . . . . . . subtract 1, collect terms
y = 1 . . . . . . . divide by 5
x = 1 +1 = 2 . . . use the expression for x to find x from y
The solution is (x, y) = (2, 1).
