Step-by-step explanation:
A. Since 7 and 11 are both rational, the sum and difference are rational.
B. Since 14 and 11 are both rational, the sum and difference are rational.
C. Since 7 is rational and StartRoot 11 EndRoot is irrational, the sum and difference are irrational.
D. Since StartRoot 7 EndRoot is irrational and 11 is rational, the sum and difference are irrational.
p² – 14p – 72 = 0
p² – 14p = 72
p² – 14p + 49 = 72 + 49
p² - 14p + 49 = 121
(p - 7)² = 121
find the square root of both sides
√(p - 7)² = √121
p - 7 = ±11
p = +11 - 7 or p = -11 - 7
p = 4 or -18
How do you find the answer to a triangle bisector?
Answers
To find the answer to a triangle bisector, you can use various methods depending on the given information.
Here's a step-by-step approach using basic geometric principles:
Start with a triangle ABC, where AB, BC, and CA are the sides, and angles A, B, and C are the corresponding angles.Choose one of the angles, let's say angle A, and draw a line segment AD from vertex A to a point D on the opposite side BC, which represents the bisector of angle A.The angle bisector theorem states that the ratio of the lengths of the segments formed by the angle bisector is equal to the ratio of the lengths of the opposite sides. So, you can use this theorem to find the length of segment BD or DC.To determine the exact length of segment BD or DC, you need additional information such as the lengths of the sides AB, BC, or CA or other angles in the triangle.You can also use trigonometric ratios such as sine, cosine, or tangent if you have the length of one side and the measures of the adjacent angles.Alternatively, if you have the coordinates of the vertices of the triangle, you can use the distance formula and the properties of lines and angles to determine the length of the bisector.For more such questions on triangle bisector

The quality and credibility of the risk analysis requires a PM to define risk probability and _____, which can then be made into a Probability and (X) Matrix.
Answers
The quality and credibility of the risk analysis requires a PM to define risk probability and impact, which can then be made into a Probability and Impact Matrix.
The quality and credibility of risk analysis in project management require a comprehensive approach that includes defining risk probability and impact. The probability of a risk event is the likelihood of it occurring, and impact is the magnitude of its consequences on project objectives. Once these factors are defined, they can be used to create a Probability and Impact Matrix, also known as a Risk Matrix, which is a useful tool for assessing and prioritizing risks.
The Probability and Impact Matrix is a grid that lists the probability of an event occurring on one axis and the impact of that event on project objectives on the other axis. The intersection of these two factors represents the level of risk associated with that event. By assigning a probability and impact score to each risk, the PM can prioritize them and allocate resources to mitigate or manage them accordingly.

Calculate the number of square feet of surface area that Shane will paint.
Answers
The 2972 square feet of surface area that Shane will paint, if he will paint the 4 rectangular sides, 2 triangular pieces and he will not paint the rectangular sections of roof.
The given is,
Shane wants to paint,
4 rectangular sides
2 triangular sides
From the given diagram,
Total surface area of paint = (4 Rectangular sides surface area ) +(2 triangular sides surface area)....(1)
Surface area of 4 rectangular sides,
For Left side(rectangle) surface area,
A = lb ...........................................................(2)
From the given diagram.
= (45.5 × 20)
= 910 Square feet
Dimensions of left side and right side are equal, so area of right side equal to the left side.
Area of right side = 910 square feet
Area of left and right sides,
= Left side area+ Right side area
= 910 + 910
= 1820 square feet
For front side area,
A= lb ...........................................................(3)
From the given diagram,
= (24 × 20 )
= 480 square feet
Dimensions of front side and back sides are equal, so area of front side equal to the back side.
Area of front side = 480 square feet
Area of front and back sides,
= front side area+ back side area
= 480 + 480
= 960 square feet
Surface area of rectangular sides,
= Area of left and right sides + Area of front and back sides
= 1820 + 960 = 2780 square feet
Surface area of 2 triangular faces,
For area of triangular sides,
\(A= \frac{hb}{2}\) ...............................................(4)
From the given values,
= \(\frac{8 (24)}{2}\)
= \(\frac{192}{2}\)
= 96 square feet
Dimensions of front side triangle and back side triangles are equal, so area of front side triangle equal to the back side triangle.
Area of front side triangle = 96 square meters
Area of front and back side triangles,
= front side triangle area+ back side triangle area
= 96 + 96
= 192 square feet
From the equation (1),
Total surface area of paint = 2780 + 192
Total surface area of paint = 2972 square feet

Answers
Option (d) is the closest to the correct form of the particular solution.To find the form of a particular solution of the given equation, we need to use the method of undetermined coefficients.
Since r1 - 31 is a root of the characteristic equation, we can assume that the particular solution has the form:
y_p = (Ae^(r1x))(Bcos(x) + Csin(x)) + Dsin(x)
where A, B, C, and D are constants to be determined.
We differentiate y_p to get:
y_p' = Ar1e^(r1x)(Bcos(x) + Csin(x)) + Ae^(r1x)(-Bsin(x) + Ccos(x)) + Dcos(x)
y_p'' = Ar1^2e^(r1x)(Bcos(x) + Csin(x)) + 2Ar1e^(r1x)(-Bsin(x) + Ccos(x)) + Ae^(r1x)(-Bcos(x) - Csin(x)) - Dsin(x)
Substituting y_p, y_p', and y_p'' into the given equation, we get:
13Ar1^2e^(r1x)(Bcos(x) + Csin(x)) + 2Ar1e^(r1x)(-Bsin(x) + Ccos(x)) - Ae^(r1x)(Bcos(x) + Csin(x)) + 36(Ae^(r1x))(Bcos(x) + Csin(x)) - 36Dsin(x) = 22* + sin(x) + 5
Simplifying and equating coefficients of like terms, we get:
13Ar1^2B + 2Ar1C - AB + 36AB = 5 (coefficients of cos(x))
13Ar1^2C - 2Ar1B - AC + 36AC = 22* + 1 (coefficients of sin(x))
-13Ar1^2A + 2Ar1B - Ae^(r1x)B + Ae^(r1x)C = 0 (coefficients of e^(r1x))
-36D = 5 (coefficients of sin(x))
Solving for A, B, C, and D, we get:
A = 0
B = 5/(13r1^2 + 36)
C = (22* + 1 - 2Ar1B - 13Ar1^2C)/(2Ar1 - AC + 36C)
D = -5/36
Therefore, the form of the particular solution is: y_p = (5/(13r1^2 + 36))(Bcos(x) + Csin(x)) - (5/36)sin(x)
where B and C are determined as shown above.
Option (d) is the closest to the correct form of the particular solution.

Answers
Using the given conditions that sin(20) = cos(2u) = tan(24) = 3, we can find the exact values of sin(2u), cos(2u), and tan(2u) using the double-angle formulas. By substituting the known values into the formulas, we can determine the exact values of these trigonometric functions.
Given sin(20) = 3, we can use the double-angle formula for sine to find sin(2u).
The double-angle formula for sine is sin(2u) = 2sin(u)cos(u). We know that sin(u) = -3/5, so we can substitute this value into the formula to calculate sin(2u).
Therefore, sin(2u) = 2(-3/5)(cos(u)).
Given cos(2u) = 3, we can use the double-angle formula for cosine to find cos(2u).
The double-angle formula for cosine is cos(2u) = cos^2(u) - sin^2(u). Since we already know sin(u) = -3/5 and cos(u) can be calculated using the Pythagorean identity (cos^2(u) = 1 - sin^2(u)), we can substitute these values into the formula to determine cos(2u).
Finally, given tan(24) = 3, we can use the double-angle formula for tangent to find tan(2u).
The double-angle formula for tangent is tan(2u) = (2tan(u))/(1 - tan^2(u)). By substituting the known value of tan(24) = 3 into the formula, we can calculate the exact value of tan(2u).

A salesperson receives a salary of $12,000 per year plus a commission of 8% of all sales over $200,000. During one year, the total sales were $620,000. Find the salespersons total earnings for the year.
Answers
Therefore , the solution of the given problem of percentage comes out to be the salesperson's yearly profits came to $45,600.
What is percentage?In statistics, "a%" is the abbreviation for a value or figure expressed as a percentage of 100. Versions with the letters "pct," "pct," or "pc" at the beginning are also rare. However, the most typical method to do so is with the percentage sign ("%"). In addition, there are no indications or a flat ratio of each individual component to the overall figure. Since numbers commonly add up to 100, they are essentially integers.
Here,
The commission earned on sales exceeding $200,000 must be calculated and added to the salesperson's basic pay of $12,000 to determine their total earnings for the year.
Sales of more than $200,000 are as follows:
=> $620,000 - $200,000 = $420,000
The commission earned is as follows because the commission rate on this sum is 8%:
=> $0.08 \times $420,000 ≈ $33,600
Including this to the $12,000 basic pay yields:
=> Total income = $12,000 + $33,600, = r$45,600.$
As a result, the salesperson's yearly profits came to $45,600.

the population standard deviation for the following scores

X 18
13
17
11
0
19
12
5
Answers
The population standard deviation for the given scores is approximately 6.157.
To calculate the population standard deviation using the computation formula for the sum of squares, we need to follow these steps:
Step 1: Calculate the mean (average) of the scores.
mean = (18 + 13 + 17 + 11 + 0 + 19 + 12 + 5) / 8 = 95 / 8 = 11.875 (rounded to three decimal places)
Step 2: Calculate the deviation from the mean for each score.
Deviation from the mean for each score: (18 - 11.875), (13 - 11.875), (17 - 11.875), (11 - 11.875), (0 - 11.875), (19 - 11.875), (12 - 11.875), (5 - 11.875)
Step 3: Square each deviation from the mean.
Squared deviation from the mean for each score: (18 - 11.875)^2, (13 - 11.875)^2, (17 - 11.875)^2, (11 - 11.875)^2, (0 - 11.875)^2, (19 - 11.875)^2, (12 - 11.875)^2, (5 - 11.875)^2
Step 4: Calculate the sum of squared deviations.
Sum of squared deviations = (18 - 11.875)^2 + (13 - 11.875)^2 + (17 - 11.875)^2 + (11 - 11.875)^2 + (0 - 11.875)^2 + (19 - 11.875)^2 + (12 - 11.875)^2 + (5 - 11.875)^2
= 37.015625 + 2.640625 + 29.015625 + 0.765625 + 141.015625 + 49.015625 + 0.015625 + 44.265625
= 303.25
Step 5: Divide the sum of squared deviations by the population size.
Population size = 8
Population standard deviation = √(sum of squared deviations / population size)
Population standard deviation = √(303.25 / 8)
≈ √(37.90625)
≈ 6.157 (rounded to three decimal places)
Therefore, the population standard deviation for the given scores is approximately 6.157.
