i might be wrong if I'm wrong try 9 as the answer

Answer:

i think 9 i might be wrong

Step-by-step explanation:

Answer:

| B | = - 9

Step-by-step explanation:

The determinant of a 2 by 2 matrix B = [tex]\left[\begin{array}{ccc}a&b\\c&d\\\end{array}\right][/tex] is

| B | = ad - bc

Then for

B = [tex]\left[\begin{array}{ccc}0&1\\9&8\\\end{array}\right][/tex]

| B | = (0 × 8 ) - (1 × 9 ) = 0 - 9 = - 9

Step-by-step explanation:

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:x=35-12

Step-by-step explanation:x equals 23

Answer:

38 degrees

Step-by-step explanation:

this is an isosceles triangle, meaning that the base angles are congruent.

the total triangle is equal to 180

so the equation would be: x=180 - (71+71)

evaluate:

x=180-142

x=38 degrees

just divide 49 by 4 and 2/3 to get the rate of mpg

Answer:

It annually drops by 20%

Step-by-step explanation:

30,000 multiplied by 20% is 6000. Subtract 6000 from 30,000 and you get 24,000. 24,000 multiplied by 20% is 4,800. Subtract 4,800 from 24,000 and you get 19,200. Etc.

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

I would say 32 but I'm so sorry if it's wrong

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
