Which expression is equivalent to sin^2 x-sin x - 2/sin x -2
A. sin x + 1

B. sin x − 1

C. sin2x

D. -sin2x

Answers

Answer 1
Set sin x to a variable, i.e. u

u^2-u-2/u-2.

Factor:

(u-2)(u+1)/(u-2)

Simplify by canceling the u-2s...

leaving u+1. Since we substituted u for sin x...
the answer is A. sin x + 1

Dan the detective looked for a number. he found a two-digit number less than 50. the sum of its digits was 12. their different was 4. what number did da find

Answers

you can quickly tell it is 48, that's the only possibility
for numbers that you cannot quickly tell, suppose the one's digit is x, and the tens' digit is y
in this case, x+y=12 and x-y=4.

Answers

Final answer:

The product of 4.6 and -5.2 is 20.12.

Explanation:

The product of 4.6 and -5.2 is calculated by multiplying the two numbers together. To do this, we can use the following steps:

Multiply the whole numbers: 4 * 5 = 20Multiply the decimal parts: 0.6 * 0.2 = 0.12Add the results: 20 + 0.12 = 20.12

Therefore, the product of 4.6 and -5.2 is 20.12.

Michael and Jacob are standing on two docks that are 20 miles apart. They are watching a ship that is out in the ocean. The angle between the dock and the line connecting Michael and the ship is 48°, and the angle between the other dock and the line connecting Jacob and the ship is 37°.

If the ship can travel to either dock, which dock would be closest? Explain your answer.

A.) Michael’s dock would be closer because the angle opposite is smaller.

B.) Jacob’s dock would be closer because the angle opposite is smaller.

C.) Michael’s dock would be closer because the docks are 20 miles apart.

D.) Jacob’s dock would be closer because the docks are 20 miles apart.

Answers

actually its A) Michael's dock would be closer because the angle opposite is smaller . 
Final answer:

Based on the basic principles of trigonometry, the ship would be closer to Jacob's dock because the dock's angle is smaller.

Explanation:

The question is asking which dock, Michael's or Jacob's, would be closer to the ship based on angles given. In the world of mathematics and specifically trigonometry, larger angles in a triangle usually indicate longer sides opposite that angle. This is because the length of the side of a triangle is directly proportional to sine of its opposite angle.

In this case, the angle between the dock and the line connecting Michael and the ship is given as 48° which is larger than the angle for Jacob (37°). When applying the basic principles of trigonometry, this tells us that the distance from the ship to Michael's dock would be greater than the one to Jacob's. Therefore, the ship would be closer to Jacob's dock. So, the answer is B: Jacob's dock would be closer because the angle opposite is smaller.

A nanosecond (ns) is an SI unit of time equal to one billionth of a second, that is, ​1⁄1 000 000 000 of a second, or 10^−9 seconds. The term combines the prefix nano- with the basic unit for one-sixtieth of a minute. A nanosecond is equal to 1000 picoseconds or ​1⁄1000 microsecond.

Answer:

A sense of respect for Aho.

Explanation:

In N. Scott Momaday's memoir "The Way To Rainy Mountain", he narrates how he embarked on rediscovering  his Kiowa heritage and the importance of preserving one's cultural background. Momaday uses a semi- autobiographical form of writing in providing the history and migration of the Kiowa people from their initial residence in Montana to Oklahoma.

In the given passage, the narrator is talking about his grandmother Aho who perfectly remembers the "Crows, who gave them the  culture and religion of the Plains". But she was never a part of those who traveled, but rather the stories told by her forefathers. Her ability to remember and preserve those memories as if she had personally experienced them impressed the narrator, who have a huge respect for her. Her memory of the "crows,.... and the Black Hills where she had never been" shows how she values the stories and tales of her own forefathers and the culture and heritage of the Kiowa people as a whole.

Solve this math problem: a bag of coins contains nickels, dimes, and quarters. there are a total of 21 coins in the bag, and the total amount of money in the bag is $3.00. there is one more dime than there are nickels. how many dimes, nickels, and quarters are in the bag?

Answer: There are 6 nickels, 7 dimes and 8 quarters in the bag.


Step-by-step explanation:  Given that the bag contains coins of nickels, dimes and quarters. There are total 21 coins in the bag and number of dimes is one more than the number of nickels.

Let 'x' be the number of nickels in the bag.

So, number of dimes will be (x+1) and number of quarters will be (21-x-x-1) i.e., (20-2x).

Since there are total $3.00 amount of money in the bag, so

[tex]0.05x+0.10(x+1)+0.25(20-2x)=3\\\\\Rightarrow\dfrac{x}{20}+\dfrac{x+1}{10}+\dfrac{20-2x}{4}=3\\\\\Rightarrow \dfrac{x+2x+2+100-10x}{20}=3\\\\\Rightarrow -7x+102=60\\\\\Rightarrow 7x=42\\\\\Rightarrow x=6.[/tex]

Therefore, number of nickels = 6, number of dimes = 6+1 = 7  and number of quarters = 20-2×6 = 8.

Thus, there are 6 nickels, 7 dimes and 8 quarters in the bag.

What is the y-intercept of the line that has a slope of -1/2 and passes through the point (2, 3)?

y=-1/2x+

Answers

Hello!

So the equation that you want to use is 
y = mx + b

Now you can plug in both the slope and your points to find b.

3 = -1/2(2) + b
3 = -1 + b
4 = b

So now that we've found b, we can use the original equation and only plug in the slope and b

y = -1/2x + 4

So to find the y-intercept, we need to plug in 0 for x

y = -1/2(0) + 4
y = 0 + 4
y = 4

Your y-intercept is (0,4)

Determine whether the lines l1 and l2 are parallel perpendicular or neither

Answers

I cannot exactly answer this question because no illustration was given to refer to. However, I can help by defining what parallel and perpendicular lines are. Lines l1 and l2 are parallel, if they do not meet at any point when you extend the line infinitely at both sides. They are perpendicular if they form right angles with each other. 
Final answer:

The lines l1 and l2 are perpendicular to each other. They form a 270° angle which means they form three right angles. Hence they are indeed perpendicular due to the fact they intersect at a point if one line is extended by 180°.

Explanation:

In this case, we are asked to determine if the lines l1 and l2 are parallel, perpendicular or neither. One critical information presented is that the two lines are perpendicular and form a 270° angle between each other.

Typically, when two lines are perpendicular, they form a right angle, which is 90°. However, a 270° angle suggests they make three right angles, meaning they do not directly intersect at a right angle, but do meet at a point if you extend one line 180° further. Hence, they are indeed perpendicular.

So, although it might seem a bit unusual, based on this information, the lines l1 and l2 are perpendicular to each other.

x - y = 4         ...2

Add both equations, then we have

As we know 1 meter = 100 centimeters

therefore, 0.2 meter = 0.2 × 100 = 20 centimeters

So Tanya need to be planted 20 centimeters apart.

if you notice the tickmarks on those sides, that means they're equal, that means is an isosceles triangle, or with two equal sides, so the 70° angle is the vertex angle, and the other two angles are just two twins, 180 - 70 = 110, split that equally to the twins, and you get that, check the picture.
