Answer:

x=9/4,x=-9/4

Step-by-step explanation:

16x^2−81=0

Step 1: Add 81 to both sides.

16x^2−81+81=0+81

16x^2=81

Step 2: Divide both sides by 16.

16x^2/16 = 81/16

x^2 = 81/16

Step 3: Take square root.

x = ±√81/16

x=2.25,x=−2.25

Convert to fraction form.

x=9/4,x=-9/4

Answer:

Anita: f(x)=42(2)^x. 3. Juan: f(x)=3^x. 4. Harrison: f(x)=5(2)^x = f(3)=5(2)^3=5(8)=40

Step-by-step explanation:

Answer:

Step-by-step explanation:

Make sure you are dealing with the same values in your directions.

1. State which two students you are studying so your instructor knows for whom each partner is responsible.  Harrison and Anita

2. Provide an exponential function representing Anita's social media shares.

f(x)= 41(2)^x

3. Provide an exponential function representing Juan's social media shares.

f(x)= 4^x

4. Using the functions for each student, predict how many shares each student's post will have received on Day 3 and then on Day 10. Justify your answers.

Harrison

f(x) =7(2)^x = f(3) = 7(2)^3 = 7(8) = 56

f(x) =7(2)^10 = f(10) = 7(2)^10 = 7(1024) = 7,168

Anita

f(x)= 41(2)^x = f(3) = 41(2)^3 = 41(8) = 328

f(x) =41(2)^10 = f(10) = 41(2)^10 = 41(1024) = 41,984

5. Based on your results, which student's post travels the fastest? How is this shown in the equation form of the functions?

Between students Harrison and Anita the post that travels the fastest was Anita at 41,984 posts.  

f(x) = 41(2)^10  

6. If you had to choose, would you prefer a post with fewer friends initially but more shares or more friends initially but fewer shares? Does your partner agree or disagree? Can you think of reasons why more or fewer shares are preferable? Justify your answer with your calculations from previous questions.

Fewer friends initially but more shares.  If you want a post to go viral you want more shares with more people. The post was viewed 41,984 times in 10 days.

This represents sharing with 2 friends for 3 days.

f(x)= 41(2)^x = f(3) = 41(2)^3 = 41(8) = 328

This represents sharing with 2 friends for 10 days.

f(x) =41(2)^10 = f(10) = 41(2)^10 = 41(1024) = 41,984

Answer:

1494.64

Step-by-step explanation:

Divide 28 by 2 = 14

14 times 3.14 times 34

I hope thats right

Answer/Step-by-step explanation:

1. x*21 = 24*14 (intersecting chords theorem)

21x = 336

x = 336/21

x = 16

2. 27*x = 45² (secant-tangent rule)

27x = 2,025

x = 2,025/27

x = 75

3. (x + 5)*5 = (4 + 6)*6 (Intersecting secants theorem)

5x + 25 = (10)*6

5x + 25 = 60

5x = 60 - 25

5x = 35

x = 35/5

x = 7

4. (4x + 2)*8 = (5x + 1)*7

32x + 16 = 35x + 7

Collect like terms

32x - 35x = -16 + 7

-3x = -9

x = -9/-3

x = 3

Answer:

4.066

Step-by-step explanation:

THIS IS THE WORK OF ANOTHER BRAINLY USER NOT MINE

In this question, we are to get the total number of hours that Irina used in watching the movie which does not include the term used for airing the commercials.

Now to calculate this, let us first take a look at the shaded segmented bar. We can see that out of the 6 horizontal bars, 5 were shaded. What this means is that 5/6 of the hours went into airing the movie while 1/6 of the hour went into airing commercials

Now, mathematically the number of hours she viewed the movie without the commercials can be calculated by adding all these 5/6 hour in the 3 hours

Mathematically that would be 5/6 + 5/6 + 5/6 = 3 (5/6) or simply 3 * 5/6 = 5/2 = 15/6 hours

The answer to your question would be D. 3/1

Answer:

x = 20

Step-by-step explanation:

Mathematically, when two triangles are similar, the ratio of their corresponding sides are equal

Thus, we have it that;

x/35 = 24/42

x = (35 * 24)/42

x = 20

Answer:

h+c=28

4h+2c=80

Step-by-step explanation:

The total amount of horses and chickens is 28. So h+c=28. Each horse has 4 legs. Each chicken has 2 legs. There are h amount of horses and c amount of chickens. So 4h+2c=80.

h+c=28

4h+2c=80
