Step-by-step explanation:
Step 1: Given data
Circumcircle radius of the polygon (R): 13.07 inSide length of the polygon (a): 10 inStep 2: Find the area of the regular polygon
We have a regular polygon with 8 sides, that is, an octagon. We can calculate the area (A) of an octagon using the following expression.
A = 2 × √2 × R²
A = 2 × √2 × (13.07 in)²
A = 483.0 in²

A study of women’s weights found that a randomly selected sample of 234 women had a mean weight of 157.3 lb. Assuming that the population standard deviation is 15.6 lb., construct a 95% confidence interval estimate of the mean weight of all women.
Answer:
(155.301 ; 159.299)
Step-by-step explanation:
Xbar = 157.3
Sample size, n = 234
Population standard deviation, σ = 15.6
The confidence interval :
Xbar ± standard Error
Standard Error = Zcritical * σ/√n
Zcritical at 95% = 1.96
Standard Error = 1.96 * (15.6/√234) = 1.999
Lower boundary : 157.3 - 1.999 = 155.301
Upper boundary : 157.3 + 1.999 = 159.299
(155.301 ; 159.299)

A cylinder with a diameter of 24 inches and a height of 8 inches has the same volume as a cone with a diameter of 12 inches.
What is the height of the cone?
A. 4 Inches
B. 16 inches
C. 48 inches
D. 96 Inches
Answer:
D. 96 inches.
Step-by-step explanation:
Radius of cylinder = 1/2 * 24 = 12 inches.
Radius of the cone = 1/2 * 12 = 6 inches.
Volume of the cylinder = pi r^2 h and volume of the cone = 1/3 pi r^2 h
So pi 12^2 * 8 = 1/3 pi * 6^2 * h
1152 pi = 12 pi h
h = 1152/12
h = 96 inches.

Answer:

Step-by-step explanation:
By applying sine rule in the triangle given in the figure,
By applying triangle sum theorem,
m∠F + m∠G + m∠H = 180°
110° + m∠G + 40° = 180°
m∠G + 150° = 180°
m∠G = 30°
[tex]\frac{sin(\angle F)}{GH}= \frac{sin(\angle G)}{HF}=\frac{sin(\angle H)}{FG}[/tex]
[tex]\frac{sin(\angle 110^0)}{f}= \frac{sin(\angle 30^0)}{g}=\frac{sin(\angle 40^0)}{13}[/tex]
[tex]\frac{sin(\angle 110^0)}{f}= \frac{sin(\angle 40^0)}{13}[/tex]
[tex]\frac{0.9397}{f}= \frac{0.6428}{13}[/tex]

Translation how many units right followed by a dilation with a scale factor of?
Help please!
Answers:
Translation 1 unit to the right.
Followed by a dilation with scale factor 2
==========================================================
Explanation:
The ultimate goal is to somehow turn the smaller blue triangle (ABC) into the green triangle (XYZ).
This means that we want to do three things:
Move point A to XMove point B to YMove point C to ZThis works because any triangle is uniquely defined by the three corner points.
Let's focus on point C. Right now, it is located at (1,1). If we move it 3 units to the right, then it arrives at (4,1). We have the correct x coordinate, but the y coordinate is not correct. We're one unit below our target, which is where Z is located.
But what we could do is instead of moving 3 units to the right, we can move 1 unit to the right. Point C will go from (1,1) to (2,1). Now apply a dilation with scale factor 2. This will multiply the coordinates by 2. So (2,1) doubles to (4,2) which is exactly where point Z is located. This process is effectively trial and error, so we got a bit lucky and didn't have to do much work to move C to Z.
-----------------
We'll do the same steps for points A and B to see if we can get them to move to X and Y respectively.
Point A is located at (2,3). Shifting one unit to the right lands us on (3,3). Double the coordinates to get to (6,6). This is where point X is located.Point B is at (3,1). It moves to (4,1) after shifting one unit to the right. Then it moves to (8,2) when we double the coordinates, and this is where point Y is located.So the process of "shift one unit to the right, double the coordinates" works for points A and B also.
Keep in mind that the order of the transformations is important. We cannot double the coordinates first, and then shift one unit to the right. If we did that, then point C would move to (3,2) which is not where point Z is located.
A guy wire connects the top of an antenna to a point on level ground at 15ft from the base of the antenna. The angle of elevation formed by this wire is 79. What is the length of the wire and the height of the antenna?
Answer:
VEFG4KLKB
Step-by-step explanation:
BLB
The length of the guy wire is approximately 74.7 feet, and the height of the antenna is approximately 72.2 feet.
Here, we have,
To find the length of the guy wire and the height of the antenna, we can use trigonometry and the concept of right triangles.
In this scenario, the guy wire represents the hypotenuse of a right triangle, and the height of the antenna represents one of the legs of the triangle.
The angle of elevation formed by the guy wire is given as 79 degrees.
Let's denote the length of the guy wire as h and the height of the antenna as a.
Using the trigonometric function sine (sin), we can relate the angle of elevation and the sides of the triangle:
sin(angle) = opposite/hypotenuse.
In this case, the opposite side is the height of the antenna (a), and the hypotenuse is the length of the guy wire (h).
sin(79°) = a/h.
To solve for h, we can rearrange the equation as:
h = a / sin(79°).
We also have another relationship between the sides of the triangle.
The base of the right triangle is given as 15 feet, and the height of the antenna is a.
Therefore, using the Pythagorean theorem, we have:
h² = a² + 15².
Now we can substitute the expression for h from the first equation into the second equation:
(a / sin(79°))² = a² + 15².
Expanding and simplifying, we get:
a² / sin²(79°) = a² + 225.
Multiplying both sides of the equation by sin²(79°), we have:
a² = sin²(79°) * (a² + 225).
Expanding again, we get:
a² = sin²(79°) * a² + 225 * sin²(79°).
Rearranging the equation, we have:
a² - sin²(79°) * a² = 225 * sin²(79°).
Factoring out a², we get:
(1 - sin²(79°)) * a² = 225 * sin²(79°).
Using the trigonometric identity sin²(θ) + cos²(θ) = 1,
we know that cos²(θ) = 1 - sin²(θ).
Therefore:
cos²(79°) * a² = 225 * sin²(79°).
Taking the square root of both sides, we have:
cos(79°) * a = 15 * sin(79°).
Simplifying, we get:
a = (15 * sin(79°)) / cos(79°).
Using a calculator or software, we find:
a ≈ 72.2 feet (rounded to one decimal place).
Now, to find the length of the guy wire (h), we can substitute the value of a into the first equation:
h = a / sin(79°).
Using a calculator or software, we find:
h ≈ 74.7 feet (rounded to one decimal place).
Therefore, the length of the guy wire is approximately 74.7 feet, and the height of the antenna is approximately 72.2 feet.
