1. Which Angles Are Represented By The Same Point On The Unit Circle As 3/4? Select All That Apply.

Answers

Answer 1

-3π/4 is an angle in the fourth quadrant that is represented by the same point on the unit circle as 3π/4.

Angles are represented by the same point on the unit circle as 3π/4, we need to first identify the quadrant in which 3π/4 lies.

3π/4 is greater than π/2 (which represents the angle at the positive x-axis intersects the unit circle) but less than π (which represents the angle at which the negative x-axis intersects the unit circle).

3π/4 lies in the second quadrant of the unit circle.

Angles in the second quadrant have the same sine value as angles in the fourth quadrant, since sine is positive in both quadrants.

Angle in the fourth quadrant that has the same sine value as 3π/4 will be represented by the same point on the unit circle.

Angles, we can use the fact that sine is an odd function, means that sin(-θ) = -sin(θ) for any angle θ.

Angle in the fourth quadrant that has the same sine value as 3π/4 by negating its sine value:

sin(-3π/4) = -sin(3π/4)

The angles that are represented by the same point on the unit circle as 3π/4 are:

3π/4 (second quadrant)

-3π/4 (fourth quadrant)

Cement costs $76 per cubic yard. What is the cost of cement for a sidewalk that is 4 in. Thick, 3ft wide,and 40 ft. Long?

Answers

Answer:

112.46 yd³

Step-by-step explanation:

1 inch = 0.0278 yds

1 feet = 0.333 yd

Thickness = 4 inches = (4 * 0.0278) = 0.1112 yds

Width = 3 feets = (3 * 0.333) = 0.999 yds

Length = 40 feets = (40 * 0.333) = 13.32 yds

Volume of sidewalk :

Thickness * Width * Length

0.1112 * 0.999 * 13.32 = 1.479702816 yd³

1 yd³ of cement = $76

Cost :

1.479702816 yd³ * $76

= 112.457414016

= 112.46 yd³

Louis wants to carpet the rectangular floor of his basement. The basement has an area of 1,176 square feet. The width of the basement is 2 3 its length. What is the length of Louis's basement?

Answers

Answer: 42 feet

Step-by-step explanation:

Let the length be x

Therefore, width = 2/3x

Area = Length × Width

Therefore, x × 2/3x = 1176

2/3x² = 1176

Divide both side by 2/3

x² = 1176 ÷ 2/3

x² = 1176 × 3/2

x² = 1764

x = ✓1764

x = 42

The length is 42 feet

A. energy has been transformed from one form to another

B. energy has been created, where it did not exist before

C. the chemicals energy of the solution had been described

D. more energy has been created than has been destroyed

Answers

The answer is B because before mixing the solution together nothing happened and it wasn’t warm, now that kayden mixed the solutions causing a chemical reaction making it to become warm. There for it will be B

According to law of conservation of energy, the statement  which best describes what has happened is that energy has been transformed from one form to another.

What is law of conservation of energy?

According to law of conservation of energy, it is evident that energy  is neither created nor destroyed rather it is restored at the end of a chemical reaction .

Law of conservation of mass and energy are related as mass and energy are directly proportional which is indicated by the equation E=mc².Concept of conservation of mass is widely used in field of chemistry, fluid dynamics.

Law needs to be modified in accordance with laws of quantum mechanics under the principle of mass and energy equivalence.This law was proposed by Julius Robert Mayer in the year 1812.

Answer: 60°

The reason for this is because the image shows that ALL the sides are EQUAL. Therefore, all the angles must be equal.
So, we know that a triangle equals a total of 180°. If we simply divide that total by 3 we get 60°.

Equilateral triangles are triangles whose all sides and angles are equal.

Since the above given triangle has 3 equal sides it is an equilateral triangle.

So, the three angles of this triangle can be 3x.

Which means :

[tex] =\tt 3x = 180[/tex]

[tex] =\tt x = \frac{180}{3} [/tex]

[tex]\hookrightarrow \tt \color{plum}x = 60°[/tex]

▪︎Therefore, x = 60°

It’s the last one because 1/2 is way more then 2/5 so I think it would be 1/5<1/2 so the last one

Answer:

2/5 < 1/2

Step-by-step explanation:

First, find the LCM for both denominators because you can't multiply 2 to get to 5. The LCM of 5 and 2 are 10, so you put that as their denominator. Then you have to think what you multiplied by 5 or 2 to get 10. For 2/5, you multiplied 5 by 2 to get 10, so multiply the numerator by 2 too. For 1/2, you multiplied 2 by 5 to get 10, so multiply the numerator by 5. Now, you will have 4/10 and 5/10. It's pretty obvious that 5/10 is bigger than 4/10, so the correct answer is 2/5 < 1/2
