Answer:
Sample Answer from Edmentum:
Suppose you want to factor the expression x2 + 2xn+n?. Given that n>0, what are the factors? Explain.
Select the correct answer below and, if necessary, fill in the answer box to complete your choice.
O A. The value of n can be any positive integer resulting in the same factor
O B. The value of n can be any positive integer resulting in the distinct factors
(Use a comma to separate answers as needed.)
O C. The value of n can be any prime integer resulting in the same factor
O
D. The value of n can be any prime integer resulting in the distinct factors
(Use a comma to separate answers as needed.)
O E. The expression cannot be factored for the given values of n.
Answer:
A. The value of n can be any positive integer resulting in the same factor
Step-by-step explanation:
Given
[tex]x^2 + 2xn + n^2[/tex] --- the right expression
[tex]n > 0[/tex]
Required
Possible values of n
[tex]x^2 + 2xn + n^2[/tex]
Expand
[tex]x^2 + 2xn + n^2 = x^2 + xn+xn + n^2[/tex]
Factorize
[tex]x^2 + 2xn + n^2 = x(x + n)+n(x + n)[/tex]
Factor out [tex]x + n[/tex]
[tex]x^2 + 2xn + n^2 = (x + n)(x + n)[/tex]
From the expression above, we can see that the result has the same factor. This means that options (b), (d) and (e) are not possible
[tex]x^2 + 2xn + n^2 = (x + n)^2[/tex]
The above also shows that n can take any positive value.
Hence: (a) is correct

David has a monthly after-tax income of $ 1430.15 1430.15 . He will be using the companies health insurance plan which costs $ 63 63 a monthand the retirement option which takes 7 7 % of his after tax income. Calculate David's Monthly Take-Home pay.
Answer:
$ 1267.
Step-by-step explanation:
Given :
David's monthly income after tax = $ 1430.15
His health insurance cost him in a month = $ 63
Percent deducted from his income after tax for his retirement option is = 7%
Therefore money left after retirement option deduction is :
$ 1430.15 - 7% of $ 1430.15
= 1430.15 - 100.11
= $ 1330.04
= $ 1330 (aprrox)
Money deducted from this amount for his health insurance plan
= $ 1330 - $ 63
= $ 1267
Therefore, David's monthly take home pay is $ 1267.
A system of equations is shown below.
8x - 2y = -4
4x - y = -2
Answer:
Step-by-step explanation:
Solve this system using elimination by addition and subtraction:
Multiplying the second equation by -2 yields the modified system
8x - 2y = -4
-8x + 2y = +4
Adding these together, we get 0 + 0 = 0 (This is always true.)

What is the longest flag pole in a hole seeds that can be shipped in a box that measures 3‘ x 3‘ x 10‘
Answer:
10.44'
Step-by-step explanation:
Given the box dimension :
3' * 3' * 10'
The length of the longest flagpole can be obtained using Pythagoras :
a² + b² = c²
Where, c = hypotenus = Longest side
a = 3 ` b = 10
c² = 3² + 10²
c² = 9 + 100
c² = 109
c = sqrt(109)
c = 10.44

What degree of rotation about the origin will cause the triangle below to map onto itself?
A. 270°
B. 180°
C. 360°
D. 90°
Answer:
the right answer will be c.360
360 degree of rotation about the origin will cause the triangle below to map onto itself.
What is Transformation?A point, line, or geometric figure can be transformed in one of four ways, each of which affects the shape and/or location of the object. Pre-Image refers to the object's initial shape, and Image, after transformation, refers to the object's ultimate shape and location.
We have to find the degree of rotation that cause the triangle below to map onto itself.
As, A figure will be mapped onto itself if it circles the graph 360 degrees.
So, there are 360 degrees in a circle, the figure has just completed a full circle and returned to where it was before rotating.
Thus, the degree of rotation is 360.

Answer:
8th term- 6,561
Step-by-step explanation:
Each term in the sequence is being multiplied by 3. For example, 3x3=9 and 9x3=27. Now, we need to continue multiplying numbers, so we can list them all here, still starting with 3.
1&2) 3x3=9
3) 9x3=27
4) 27x3=81
5) 81x3=243

Step-by-step explanation:
Here is the complete question :
Cookies are on sale! Today each cookie costs $0.75 less than normal price. Right now if you buy 7 of them it will only cost you $2.80!
write an equation to determine the normal price of each cookie (C). Find he normal price of each cookie.
the discounted price of one cookie = total sales price of 7 cookies / 7
$2.8 / 7 = $0.4
it was stated in the question that the sales price is $0.75 less than normal price. Thus the normal price of the cookie = $0.4 + $0.75 = $1.15
the equation : [tex]\frac{2.8}{7} + 0.75[/tex]

Cyber Monday Shopping A survey of 1000 U.S. adults found that 33% of people said that they would get no work done on Cyber Monday since they would spend all day shopping online. Find the 95% confidence interval of the true proportion.
Answer:
(0.301 ; 0.359)
Step-by-step explanation:
Sample size, n = 1000
Phat = 0.33
(1 - phat) = 1 - 0.33 = 0.67
Zcritical at 95% = 1.96
Confidence interval :
Phat ± margin of error
Margin of Error = Zcritical * sqrt[(phat(1 - phat)) /n]
Margin of Error = 1.96 * sqrt[(0.33 * 0.67) / 1000]
Margin of Error = 1.96 * 0.0148694
Margin of Error = 0.0291440
Lower boundary = (0.33 - 0.0291440) = 0.300856
Upper boundary = (0.33 + 0.0291440) = 0.359144

Answer:
1. The volume of the cylinder is 263 [tex]cm^{3}[/tex].
2. The volume of the cylinder is 12 [tex]m^{3}[/tex].
3. The volume of the cylinder is 3165.1 [tex]cm^{3}[/tex].
4. The radius of the cylinder is 3.6 cm.
5a. Area of the base is 50.2 [tex]cm^{2}[/tex].
5b. The curved surface area of the pencil holder is 351.7 [tex]cm^{2}[/tex].
5c. The surface are of the pencil holder is 452.2 [tex]cm^{2}[/tex].
Step-by-step explanation:
1. The given shape is a cylinder, so that;
volume of a cylinder = [tex]\pi[/tex][tex]r^{2}[/tex]h
= 3.14 x [tex](3.8)^{2}[/tex] x 5.8
= 262.98128
The volume of the cylinder is 263 [tex]cm^{3}[/tex].
2. This is also a cylinder, but with a given diameter.
radius = [tex]\frac{diameter}{2}[/tex]
= [tex]\frac{1.2}{2}[/tex] = 0.6 m
volume of a cylinder = [tex]\pi[/tex][tex]r^{2}[/tex]h
= 3.14 x [tex](0.6)^{2}[/tex] x 10.6
= 11.98224
The volume of the cylinder is 12 [tex]m^{3}[/tex].
3. volume of a cylinder = [tex]\pi[/tex][tex]r^{2}[/tex]h
= 3.14 x [tex]6^{2}[/tex] x 28
= 3165.12
The volume of the cylinder is 3165.1 [tex]cm^{3}[/tex].
4. volume of a cylinder = [tex]\pi[/tex][tex]r^{2}[/tex]h
239 = 3.14 x [tex]r^{2}[/tex] x 6
239 = 18.84 [tex]r^{2}[/tex]
[tex]r^{2}[/tex] = [tex]\frac{239}{18.84}[/tex]
= 12.6858
r = [tex]\sqrt{12.6858}[/tex]
= 3.5617
The radius of the cylinder is 3.6 cm.
5. Area of the base = [tex]\pi[/tex][tex]r^{2}[/tex]
radius = [tex]\frac{diameter}{2}[/tex]
= [tex]\frac{8}{2}[/tex] = 4 cm
Area of the base = 3.14 x [tex]4^{2}[/tex]
= 50.24
Area of the base is 50.2 [tex]cm^{2}[/tex].
5b. Area of the curved surface of the pencil holder = 2[tex]\pi[/tex]rh
= 2 x 3.14 x 4 x 14
= 351.68
The curved surface area of the pencil holder is 351.7 [tex]cm^{2}[/tex].
5c. Surface area of the pencil holder = 2[tex]\pi[/tex]rh + 2[tex]\pi[/tex][tex]r^{2}[/tex]
= 2[tex]\pi[/tex]r(h + r)
= 2 x 3.14 x 4 (14 + 4)
= 452.16
The surface are of the pencil holder is 452.2 [tex]cm^{2}[/tex].
