Answer:
NO , an angle is not trisected using only a compass and a straight edge.
Step-by-step explanation:
We are given two tools a compass and a straight edge
We need to tell if an angle is trisected using them or not.
Answer is NO , an angle is not trisected using only a compass and a straight edge.
When we draw a semicircle by point pointer of compass at vertex of angle and then draw a line using points we get when semicircle intersects the arms of the angle. We get angle Bisection.
We again try to bisect we get four equal angles not Three.
So It is impossible to make odd numbers of equal angles from a given angle using a compass and a straight edge.

State the amplitude and period of f(x)= 3cos 9/5 (t)
Answer:
The period is [tex]\dfrac{10\pi}{9}[/tex] and the amplitude is 3.
Step-by-step explanation:
The period goes from one peak to the next (or from any point to the next matching point). The amplitude is the height from the center line to the peak.
The period of the function [tex]y=a\cos (bx)[/tex] is [tex]T=\dfrac{2\pi }{b}[/tex] and the amplitude is [tex]|a|.[/tex]
Consider the function [tex]f(t)=3\cos \left(\dfrac{9}{5}t\right).[/tex]
The period for the function [tex]f(t)[/tex] is
[tex]T=\dfrac{2\pi}{\frac{9}{5}}=\dfrac{2\pi}{1}\cdot \dfrac{5}{9}=\dfrac{10\pi}{9}[/tex]
and the amplitude is 3.
The amplitude of the function f(x) = 3cos(9/5 t) is 3, and the period is approximately 3.4907 units of time.
Explanation:The amplitude of the function f(x) = 3cos(9/5 t) is 3. This is because the amplitude A of a cosinusoidal function of the form x(t) = Acos(wt + φ) is the coefficient in front of the cosine, which describes the peak-to-peak swing of the wave.
The period T of the function can be found using the relationship between angular frequency w and the period T, which is T = 2π/w. Here, the angular frequency w is 9/5. Thus, the period T is 2π × (5/9), which simplifies to approximately 3.4907 units of time.
Carol has a small Copley of a painting. The dimensions of her copy are shown at the right. The scale of the copy is 0.5 inches: 12 centimeter.
Question A) Find the dimensions of the original painting.
Question B) Find the area of the original painting.
Question C) One centimeter is equal to approximately 0.033 foot. Find the dimensions of the original painting in feet. Round to the nearest thousandth.
Answer:
Question A: The dimensions of the original painting are 42 cm by 126 cm.
Question B: The area of the original painting is [tex]5292cm^2[/tex]
Question C: The dimensions of the painting in feet are 1.386 ft by 4.158 ft.
Step-by-step explanation:
Question A:
The scale of the copy is
0.5 inches:12 centimeter.
This means that 1 inch on the scale is 24 centimeters.
Therefore the width of the original painting is:
[tex]1.75*24cm=42cm[/tex]
and the height of is:
[tex]5.25*24cm=126cm[/tex]
Therefore the dimension of the original painting are 42 cm by 126 cm.
Question B;
The area of the original painting is just width multiplied by height:
[tex]Area=42cm*126cm=5292cm^2[/tex]
Question C:
We convert the dimensions of the painting from centimeters to feet:
[tex]width=42cm*0.033\frac{feet}{cm} =1.386\:feet.[/tex]
[tex]height=126cm*0.033\frac{feet}{cm} =4.158\:feet.[/tex]
Therefore the dimensions of the original painting in feet are 1.386 ft by 4.158 ft.
Answer:
(A) 42 cm by 126 cm.(B) 5,292 square centimeters.(C) 1.386 feet by 4.158 feetStep-by-step explanation:
The scale of the copy is 0.5 : 12, which means 0.5 inches of the copy represents 12 centimeters actual.
From the given scale we can deduct that 1 inch equals 24 centimeters.
So, the dimensions of the original are
[tex]1.75 \times 24 =42[/tex]
[tex]5.25 \times 24= 126[/tex]
Therefore, the original painting has dimensions 42 cm by 126 cm. (A)
Notice that the original painting is also rectangular, so its area is
[tex]A_{original}=42 \times 126 = 5,292 cm^{2}[/tex] (B)
Now, if 1 centimeter is equivalen to 0.033 foot, the dimensions of the original painting in feet are
[tex]42 \times 0.033 =1.386 ft\\126 \times 0.033=4.158 ft[/tex]
Therefore, the dimensions in feet are 1.386 feet by 4.158. (C)

Lets substitute in what we know
sin 30 sin B sin 45
---------- = ---------- = ---------
5sqrt(2) AC BC
We can calculate angle B because all three angles have to add to 180
A+B+C = 180
45+B + 30 = 180
75+B=180
Subtract 75 from each side
75-75+B=180-75
B =105
sin 30 sin 105 sin 45
---------- = ---------- = ---------

Using cross products and the first and third columns
BC sin 30 = 5 sqrt (2) sin 45
BC * .5 = 5 sqrt(2) * 1/2 sqrt(2)
1/2 BC = 5
Multiply by 2
2*1/2 BC = 5 *2
BC =10
Using cross products and the first and second columns
BC sin 30 = 5 sqrt (2) sin 105
sin 105 is really ugly as an exact answer

5 used cars for sale. They have a mean price of $7000
. What is the total price of all 5
cars?
Step-by-step explanation:
We are given total number of cars = 5 cars.
The mean of all of five cars = $7000.
Note: Total sum/value could be calculated by multiplying mean with the total numbers we have.
Total price = Mean × Total number of cars.
According to problem, mean is 7000 and total number of cars is 5.
Therefore, Total price of all 5 cars = 7000 × 5 = $35000.The total price of all 5 cars is $35000, calculated by multiplying the mean price ($7000) by the number of cars (5).
Explanation:The subject of this question is Mathematics, specifically mean and total values. The mean price of the cars is given as $7000. The mean is calculated by dividing the total price by the number of items, in this case, cars. To find the total price, we therefore multiply the mean price by the number of cars. So, $7000 (mean price of each car) times 5 (total cars) equals $35000. Therefore, the total price of all 5 cars is $35000.

What is a real world problem for 2(n+20)=110
To solve the algebraic equation '2(n+20)=110', we first divide by 2, yielding 'n+20=55', and then subtract 20 to find 'n=35'. A real-world example could be calculating an initial inventory of items before doubling and adding 20 to reach a target inventory.
Explanation:The student's question, 'What is a real world problem for 2(n+20)=110?' can be seen as a basic algebra question. To solve for n, we start by dividing both sides of the equation by 2, giving us n+20 = 55. Then we subtract 20 from both sides, which leaves us with n = 35.
A real-world interpretation of this equation could be a scenario where someone has twice the number of objects plus an additional 20 objects, and they want to end up with 110 objects in total. To find out the original number of objects, they would perform the calculations above. In this case, the real-world problem could involve an initial inventory of 35 items that needs to be doubled and then 20 more added to achieve a target inventory of 110 items.

what is the slope of the line i ready
The slope of the given line, determined from the graph and the point-slope form, is -0.5.
The slope of a line is a measure of its steepness. To determine the slope from a graph, you can use the point-slope form and the slope-intercept form of a linear equation.
Given a graph with points (0,1) and (0.5,0), you can calculate the slope as follows:
Use the point-slope form of a linear equation:
(y - y1) / (x - x1) = (y2 - y1) / (x2 - x1)
Where (x1, y1) and (x2, y2) are points on the line.
Plug in the coordinates of the given points:
(y - 1) / (x - 0) = (0 - 1) / (0.5 - 0)
Simplify:
(y - 1) / x = -1 / 0.5
Further simplify:
2(y - 1) = -x
Rearrange to isolate y:
2y - 2 = -x
2y = -x + 2
y = (-1/2)x + 1
Compare this equation to the slope-intercept form, y = mx + c. In this case, the slope (m) is -1/2, which is equivalent to -0.5.

A six-sided die with sides labeled 1 through 6 will be rolled once. Each number is equally likely to be rolled.
What is the probability of rolling a number greater than 2?
Write your answer as a fraction.
Answer:
2/3
Step-by-step explanation:
Given that a six sided die with sides labelled with numbers 1,2,3,4,5 and 6 is rolled once.
Since die is said to be equally likely for each number, die is unbiased
P(1) = P(2)=...=P(6) = 1/6
For a number greater than 2, we must not include 2 and hence numbers can be 3 or 4 or 5 or 6
Probability of rolling a number >2 = Probability of rolling 3 or 4 or 5 or 6
= P(3)+P(4)+P(5)+P(6)
= 1/6+1/6+1/6+1/6
=4/6
=2/3
Required probability = 2/3
The probability of rolling a number greater than 2 on a six-sided die is 2/3. This is because there are 4 numbers greater than 2 on the die and the total number of possible outcomes when the die is rolled is 6.
Explanation:The subject of this question is probability, a topic in mathematics. To solve this problem, we need to first understand the total possible outcomes when rolling a six-sided die. The outcomes are the numbers 1 through 6, so we have 6 possible outcomes.
To find the probability of rolling a number greater than 2, we need to determine how many outcomes match this condition. The numbers greater than 2 on a six-sided die are 3, 4, 5, and 6. So, there are 4 favorable outcomes.
Probability is calculated by dividing the number of favorable outcomes by the total number of outcomes. So, the probability of rolling a number greater than 2 on a six-sided die is 4/6, which simplifies to 2/3.
