Answer 1

Answer:

1 is b

2 is c

3 is b

Step-by-step explanation:

Initial co-ordinate of p = ( 2, -2)

Rule for rotation 180° about the origin

(x,y) ----> ( -x , -y )

Meaning of the rule: To find the coordinates of a point that was rotated 180° about the origin all we have to do is add negative signs in front of the x and y values of the coordinates. THE NUMBER STAYS THE SAME. THE ONLY THING THAT CHANGES IS THE SIGN

* add - to the coordinates *

- ( 2 , -2 )

-1 * 2 = -2

-1 * -2 = 2

we end up with ( -2, 2 )

Hence the answer is B

For this one a rectangle was dilated and we have to find the scale factor and the new width.

We are given the pre image width (3) and length (4) and the new image length (12)

We can find the scale factor by dividing the new image length by the pre image length ( Note that you have to use corresponding sides. Like pre image height over new image height or pre image length over new image length. etc. )

So scale factor = 12 / 4  or 3

Now to find the new image width

We can do this by multiplying the pre image width (3) by the scale factor (3)

So new image width = 3 * 3

3 * 3 = 9

Hence the width of the enlarged  print is C 9 inches

For this one we need to find x using angle rules

The angles shown are supplementary angles meaning that the sum of the two angles is 180

That being said we can create an equation to solve for x

180 = 64 + 4x + 16

Now we just solve using basic algebra

step 1 combine like terms

64 + 16 = 80

now we have 180 = 4x + 80

step 2 subtract 80 from each side

80 - 80 cancels out

180 - 80 = 100

now we have 100 = 4x

step 3 divide each side by 4

100/4 = 25

4x/4=x

we're left with x = 25

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

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

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

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.

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

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.

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

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

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

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

Jasmine is borrowing $5,200 to purchase her first used car. She can take out a loan
from the car dealership for 42 months at an 8% annual simple interest, or she can
borrow the money from her bank for 36 months at a 7% annual simple interest
rate.
Calculate the interest charged for the car dealership loan.

Answers

Answer:

$1456

Step-by-step explanation:

5200 × 8% = $416(interest in 1 yr/12mnths)

42months ÷ 12months(1year) = 3.5 yrs

$416 × 3.5 yrs = $1456(interest in 42mnths/3.5yrs)

The value of the car depreciates annually by 20%.
The value of the car depreciates annually by 80%.
The value of the car depreciates annually by $6,000.
The value of the car depreciates annually by $4,800.

Answers

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.
