Answer:

Step-by-step explanation:

we need that theta angle .. soooo.... use SOH CAH TOA  to remind yourself how the trig functions fit on the triangle.....

since we have all 3 side any one of the above trig functions would work.  as a side note.. Tan is limited to the 1st quadrant on a calculator.. so maybe Cos is a good choice. although it would work in this case....

sooo ....

Cos(Ф) = Adj / Hyp

Ф = arcCos( 24 /25)

Ф ≈16.26°

I don't have csc on my calculator but I know that  1/sin  = csc  sooo

csc(16.26)=1/sin(16.26) ≈ 3.57

sec(16.26)= 1/cos(26.26) ≈ 1.041

cot(16.26) = cos(16.26) / sin(16.26) ≈3.476

Answer:

csc(0)= 25/7

sec(0)= 25/24

solve: x2 + 8x - 9 = 0
please i need it urgently​

Answers

Answer:

x = 1 or x = -9

Step-by-step explanation:

Solve for x over the real numbers:

x^2 + 8 x - 9 = 0

Hint: | Solve the quadratic equation by completing the square.

Add 9 to both sides:

x^2 + 8 x = 9

Hint: | Take one half of the coefficient of x and square it, then add it to both sides.

Add 16 to both sides:

x^2 + 8 x + 16 = 25

Hint: | Factor the left hand side.

Write the left hand side as a square:

(x + 4)^2 = 25

Hint: | Eliminate the exponent on the left hand side.

Take the square root of both sides:

x + 4 = 5 or x + 4 = -5

Hint: | Look at the first equation: Solve for x.

Subtract 4 from both sides:

x = 1 or x + 4 = -5

Hint: | Look at the second equation: Solve for x.

Subtract 4 from both sides:

Answer: x = 1 or x = -9

Residents of three counties were polled to find the percentage of residents who are Republican or Democrat. A 4-column table with 4 rows. The first column has no label with entries county 1, county 2, county 3, total. The second column is labeled Democrat with entries 4,050; 3,925; 2,100; 10,075. The third column is labeled Republican with entries 2,470; 6,010; 5,950; 14,430. The fourth column is labeled total with entries 6,520; 9,935; 8,050; 24,505. Find the following relative frequencies to the nearest tenth of a percent. Republican residents of County 1: % Democratic residents of County 1: % Total Republican residents: % Total Democratic residents: %

Answers

Using the concept of relative frequency, it is found that:

Republican residents of County 1: 37.9%.Democratic residents of County 1: 62.1%.Total Republican residents: 58.9%.Total Democratic residents: 41.1%.

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

A relative frequency is the number of desired outcomes divided by the number of total outcomes.

To find it as a percentage, we multiply by 100%.

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

The table used is the image at the end.

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

County 1 has 6,520 residents, out of which 2,470 are Republican.

2470*100%/6520 = 37.9%

Thus:

Republican residents of County 1: 37.9%.

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

County 1 has 6,520 residents, out of which 4,050 are Democratic.

4050*100%/6520 = 62.1%

Thus:

Democratic residents of County 1: 62.1%.

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

Total of 24,505 Residents, 10,075 Democrats and 14,430 Republicans.

10075*100%/24505 = 41.1%

14430*100%/24505 = 58.9%

Thus:

Total Republican residents: 58.9%.

Total Democratic residents: 41.1%.

What is the exact question? It seems like you are asking for the Pythagorean theorem. Ok, I’ll try to help if that’s the case.

a^2 + b^2 = c^2
4^2 + 5^2 = c^2
16 + 25 = c^2
41 =c^2
6.403124237432849 = c

So now since we have the answer, we need to figure out if this result and 6 are equal.

6^2 = 36

25 + 16 = 41

41 and 36 are not equivalent so if the case is that u want me to find the Pythagorean theorem, then the answer is that they aren’t equal. And the real answer is that c equals 6.403124237432849. Which means that 4in, 5in, 6in is not the correct order. And that 16in, 25, 41 is the correct order.

You can paint 75 square feet of a surface every 45 minutes. Determine how long it takes you to paint a wall with the given dimensions. 8 ft $\times$ 5 ft

Answers

Answer:

24 minutes

Step-by-step explanation:

The Dimensions of the wall are given as:

8ft × 5ft = 40ft² or 40 square feet

We are told that: You can paint 75 square feet of a surface every 45 minutes.

Hence:

75 ft² = 45 minutes

40 ft² = x minutes

Cross Multiply

75 ft² × x = 40 ft² × 45 minutes

x = 40 ft² × 45 minutes/75 ft²

x = 24 minutes

Therefore, It will takes you 24 minutes to paint a wall with dimensions 8ft × 5 ft

The numbers 20 through 30 are written on cards and placed in a box. Explain whether the events of choosing a number that is a multiple of 3 or choosing a number that is a multiple of 4 are mutually exclusive.

A. Mutually Exclusive
B. Not Mutually Exclusive

Answers

Answer:

A. Mutually Exclusive is the correct answer

The events of choosing a number that is a multiple of [tex]3[/tex] or choosing a number that is a multiple of [tex]4[/tex] are not mutually exclusive.

What is Mutually Exclusive ?

Mutually Exclusive means when two sets have no common elements.

What is Not Mutually Exclusive ?

Not Mutually Exclusive means when two sets share common elements.

We have,

Cards numbered [tex]20[/tex] to [tex]30[/tex].

Let's

Set [tex]A =[/tex] Multiple of [tex]3[/tex]

i.e. Set [tex]A = \ \{ 21, 24,27,30\}[/tex]  

Set [tex]B =[/tex] Multiple of [tex]4[/tex]

i.e. Set [tex]B = \{20,24,28\}[/tex]

So, Set [tex]A[/tex] and Set [tex]B[/tex] have common element [tex]24[/tex], so we call them Not Mutually Exclusive, from the mentioned definition we find out this.

Hence, we can say that the events of choosing a number that is a multiple of [tex]3[/tex] or choosing a number that is a multiple of [tex]4[/tex] are not mutually exclusive.

Answer:

9.) 5x - 18 = 4x + 7 10.) x = 25 11.) m∠MNQ = 107° 12.) m∠MNR = 73°

Step-by-step explanation:

9. & 10.)

∠MNQ and ∠RNP are vertical angles meaning they are equivalent to each other. Knowing that, we can set their values equal to each other and solve for x.

5x - 18 = 4x + 7 (Given)

x - 18 = 7 (Subtract 4x on both sides)

x = 25 (Add 18 on both sides)

Therefore, we know the equation is 5x - 18 = 4x + 7 and we know that x = 25.

Now we can solve for the angles.

11.)

5(25) - 18

125 - 18 = 107

Therefore, m∠MNQ = 107°.

12.)

∠MNR and ∠MNQ are supplementary angles meaning their angles will add up to 180°

∠MNR + 107 = 180

∠MNR = 73

Therefore, m∠MNR = 73°.

Was it because of the bet or did I actually what to hang out with her? Was it just because my parents were arguing again and I needed to get out? What the heck.. of course its because of the bet and maybe because I wanted to get away from my parents. She is not fun and super rude. Id never want to hang out with her on my own. This is definitely for the bet. All that laughter and fun was totally fake. Shes still an annoying spoiled brat.. right? I really dont know how to see her anymore because right now she looks really adorable feeding the ducks. She has a big smile on her face and she generally looks really happy. Happy suits her. What am I even saying? This is kinda bad, Im actually having... fun. I even almost told her about my parents fighting.. she definitely can not know about that. She wouldnt understand. While Im deep in thought, I notice her dump the rest of the bag of bread crumbs in the pond and giggle. I like when she laughs. Wait, no I dont. Pretty boy! Dump the rest of your crumbs to the ducks! I smile and do as she says. My name is Seth. You can stop calling me pretty boy. She looks at me with a grin and says, You know, I think I like pretty boy better. She laughs and I glare at her. Thats what I said to her earlier when Ava told me her name. Well, I guess I am pretty. I say in a confident tone. She looks at me and responds, Not even close. I glare at her some more. Shes definitely still mean and bratty. Aww, did I make you mad? She asks in a mocking tone. Of course she did but Im not admitting that to her. I walk towards her and she stops laughing and asks, What are you doing? I grin at her secretly knowing that shes going to hate me even more after I do this. I walk even closer and push her into the pond. She screams and she hits the water and is completely soaked. Oh my gosh! What is wrong with you?! I hate you! She screams at me but Im too busy laughing to pay attention. The next thing I know, Im in the pond too. She grabbed my leg and pulled me in. I should have seen that coming. Now shes dying of laughter. I cant believe you just did that! I say to her. She starts laughing again and through her laughter says, Oh come on! You totally deserved that! I smile and say, I guess I did. She giggles. That annoyingly adorable laugh she has is driving me crazy. We should go, its getting late. I say to her. Yeah, probably. She replies.
