Answers

Answer:

Step-by-step explanation:

This is a right triangle because angle V is 90. Draw out a right triangle and put V at the 90 degree angle. It doesn't matter where you put U or T; you get the same cos value for T regardless of how you place your other 2 angles. The things you need to know are that UT is the hypotenuse of the triangle, side VU is across from angle T, and side TV is across from angle U.

The cos ratio is side adjacent to the reference angle over the hypotenuse.

Our reference angle is T, so we are looking for the side next to T that is NOT the hypotenuse. This side measures 33; the hypotenuse measures 65, so the tangent ratio of T is

AB is tangent to circle C. Find the value of r. Please answer Asap

Answers

Answer:

3

Step-by-step explanation:

a tangent to a circle makes right angle with the radius at that point ( here the point is B)

thus,

ABC is a right angled triangle

AC being the hypotenuse AB being the adjacentBC being the opposite

By Pythagoras theorem :-

By Pythagoras theorem :-AC² = AB² + BC²

(r + 2)² = 4² + r²

r² + 4 + 4r = 16 + r²

subtracting r² from both sides and taking 4 common

4(1 + r) = 16

diving both sides by 4

1 + r = 4

r = 3 units

The value of r is,

⇒ r = 3 units

What is Pythagoras theorem?

The Pythagoras theorem states that in a right triangle, the square of the hypotenuse is equal to the sum of the square of the other two sides.

Given that;

AB is tangent to circle C.

Now,

By Pythagoras theorem, we get:-

AC² = AB² + BC²

(r + 2)² = 4² + r²

r² + 4 + 4r = 16 + r²

subtracting r² from both sides and taking 4 common

4(1 + r) = 16

diving both sides by 4

1 + r = 4

r = 3 units

Thus, The value of r is,

⇒ r = 3 units

Here’s why:  

⸻⸻⸻⸻

[tex]\boxed{\text{Solving for 'x'...}}\\\\-8x-4(x-4)=88\\-------------\\\rightarrow -8x-4x+16=88\\\\\rightarrow -12x + 16 = 88\\\\\rightarrow -12x + 16 - 16 = 88 - 16\\\\\rightarrow -12x = 72\\\\\rightarrow \frac{-12x=72}{12}\\\\\rightarrow \boxed{x=-6}[/tex]

⸻⸻⸻⸻

»»————- ★ ————-««  

Hope this helps you. I apologize if it’s incorrect.  

Answer: x = -6

Step-by-step explanation: Start by changing the - 4 to plus a negative 4 so that you know you're distributing a -4 through the parentheses.

So we have -8x - 4x + 16 = 88.

Simplifying the left side further gives us -12x + 16 = 88.

Now subtract 16 from both sides to get -12x = 72.

From here it should be easy to find the x = -6.

Help please !!! At a local Brownsville play production, 420 tickets were sold. The ticket prices varied on the seating
arrangements and cost $8, $10, or $12. The total income from ticket sales reached $3920. If the
combined number of $8 and $10 priced tickets sold was 5 times the number of $12 tickets sold, how
many tickets of each type were sold?

Answers

Answer:

n = 12$    x = 8$   y = 10$     where n, x, and y are number of tickets

12 n + 8 x + 10 y = 3920     and n + x + y = 420

12n + 8 (x + y) + 2 y = 3920

12 n + 8 (5 n) + 2 y = 3920        since 5 (x + y) = n

52 n + 2 y = 3920   or  y = 1960 - 26 n

Also, n + x + y = 420   or n + 5 n = 420   since x + y = 5 n

n = 70    so 70 of the $12 were sold

And since y = 1960 - 26 n     we have y = 140 tickets

Now 12 * 70 + 8 x + 140 * 10 = 3920

This gives x = 210 tickets

Check:   210 + 140 + 70 = 420 tickets

Also, 12 * 70 + 210 * 8 + 140 * 10 = 3920

Have you ever been canoeing? I went on a canoeing trip with my mom, dad, and two brothers when I turned 13. It was one of the best days of my life. It was exciting, scary, and challenging all at once. At first I couldn’t believe those long, narrow pieces of wood could hold all five of us. But our instructor told us that canoes have been around for many years. He also told us some interesting facts about the history of canoe, like how American Indians used canoes as a way to travel quickly.

He patted the wood of the canoe we would be using. “It’s made of an old tree trunk,” he said.

I asked the question that had been bothering me ever since I saw our canoe. “Can it really hold all of us?” I pointed to my brothers and me. “It looks like the bottom could fall right off.”

The instructor laughed. “Oh, you’ll be surprised how strong this wood is. If our customers were always drowning, we’d have a 'sinking' business on our hands.”

He laughed some more at his own joke. Then he became serious and showed us how to keep our balance while getting into and out of the boat. He also showed me how to grip the paddle so that my left hand would guide the boat and my right hand would give the paddle power.

Canoeing is dangerous, and only people who are experts can do it.

The graph of F(x) can be compressed vertically and shifted to the right to produce the graph of G(x) . If F(x) = x ^ 3 , which of the following could be the equation of G(x) ?

Answers

Given:

The function is:

[tex]F(x)=x^3[/tex]

To find:

The function G(x) if the graph of F(x) can be compressed vertically and shifted to the right to produce the graph of G(x).

Solution:

The transformation is defined as

[tex]g(x)=kf(x+a)+b[/tex]                .... (i)

Where, k is stretch factor, a is horizontal shift and b is vertical shift.

If 0<k<1, then the graph compressed vertically by factor k and if k>1, then the graph stretch vertically by factor k.

If a>0, then the graph shifts a units left and if a<0, then the graph shifts a units right.

If b>0, then the graph shifts b units up and if b<0, then the graph shifts b units down.

It is given that F(x) can be compressed vertically and shifted to the right to produce the graph of G(x). So, the value of k must be lies between 0 and 1, and a<0.

In option A, [tex]0<k<1[/tex] and [tex]a<0[/tex]. So, this option is correct.

In option B, [tex]0<k<1[/tex] and [tex]a>0[/tex]. So, this option is incorrect.

The sides of a triangle have lengths 2, 3, and 3. What kind of triangle is it?

Answers

Answer: Isosceles triangle

This is because the triangle has exactly two sides that are the same length.

If all three sides were the same length, then it would be equilateral.

If neither of those cases, then we consider the triangle scalene.

Answer: Isosceles triangle

Explanation: An isosceles triangle is a type of triangle in which two sides share the same length, and two angles share the same degree. Using the lengths of the triangle provided to us, we can tell that this shape is an isosceles triangle because two of the sides are equal.

Cans of soda at a local store a six-pack of soda costs $2.59 and indivdual cans cost $0.80. What is the maximum of cans of soda that can be purchased for $15​

Answers

Answer:  30 cans (buy them by the six-pack; so you'd buy 5 six-packs)

==============================================================

Explanation:

Let's say you buy six-packs only. Divide the amount of money you have over the cost per six-pack.

15/(2.59) = 5.7915 which rounds down to 5.

If you buy six-packs only, then you can buy a max of 5 of them. That gets you 5*6 = 30 cans of soda.

-------------

Now let's say you buy individual cans only. We'll use the same idea mentioned earlier but this time divide over 0.80

15/(0.80) = 18.75 which rounds down to 18

We round down because we can't buy that 19th can of soda (note how 19*0.80 = 15.2 which is larger than 15).

So if you buy individual cans only, then you can get a max of 18 cans.

We see that it's better to go with the six-pack option (in the first section) since we can get 30 cans compared to 18 cans.

does the point (-4, 2) lie inside or outside or on the circle x^2 + y^2 = 25?​

Answers

Answer:

Since at maximum speed, an airplane travels 1680 miles against the wind in 5 hours, and flying with the wind. the plane can travel the same distance in 4 hours, to determine what is the speed of the plane with no wind, the following calculation must be performed:

Against the wind = 1680/5 = 336

With the wind = 1680/4 = 420

420 - ((420 - 336) / 2) = X

420 - 42 = X

378 = X

Therefore, the speed of the plane with no wind is 378 miles per hour.

This discipline eliminates the intake of meat and in some cases also the consumption of dairy products and eggs. Are there enough reasons to make you change your eating habits? My purpose is to prove that vegetarianism is the diet that offers more benefits to our health, spirit, and society.Nowadays, health is the number one individual and governmental concern. Health is a fragile factor and its behavior relies mostly on the nutritional quality of the food we ingest. A balanced non-vegetarian diet allows the consumption of all four main food groups including meat and other animal by-products that are important protein and fat sources. Most of us consume more proteins and fats than we need. An excess of proteins can cause kidney failure and/or osteoporosis, and a high-fat diet can eventually lead to heart disease, cancer, obesity, and diabetes. On the other hand, vegetarians get protein from grains, beans, vegetables, and low-fat food. This is how they reduce the risk of most diseases caused by fats. It is a myth to believe that vegetarians don't get enough proteins or that their diet is not balanced because they don't eat meat. The key isvariety and accurate combinations of energy and protein sources. If I were asked to describe a vegetarian, I would immediately mention they are very disciplined people. It has been proven that there exists a remarkable correlation between the people who succeed and people who follow a disciplined lifestyle. People who are faithful to the disciplines they have acquired show integrity, a remarkable behavior and they are usually in a good mood. Vegetarians, always concerned about quality and discipline, develop a greater social responsibility that motivates them to improve their environment.Moreover, environmental issues have been capturing public attention because of their relevancy and increasing deterioration of our quality of life. If you are concerned about the environment, consider that massive meat production can have a negative impact on tropical rain forests, soil stability, and air and water quality. Large extensions of forests have been cut and changed into grasslands that provide cattle with food. To conserve grasslands, fertilizers and other chemical substances are used; consequently, soil and water resources are polluted. Even though there are methods that avoid this kind of deterioration, producers prefer to ignore them so they can keep satisfying the increasing meat demand without affecting their production rates.Vegetarians' life spans are increased and through this discipline they learn to live quality life in all the possible aspects. Besides, their beliefs are congruent with their lifestyle and they take responsibility and action for problems within their own bodies and in their surroundings. Take a look at yourself. Is your health at risk? Have you been able to reach your goals? Are you a factor of change and improvement within your society? You must at least try becoming a vegetarian now that you know it is a tempting challenge and an exciting experiment that has advantages and no risks. Do it for your body, for your lifestyle, or for your environment, but do it. Stop letting others have all the credit, the fun, and the quality.1.
