Gary rents three DVDs each week at Fantastik Flicks. Write an algebraic expression for Wn, the total number of points earned in the nth week

Answers

Answer 1

For the nth week, the total points earned in the DVD rentals is [tex]p_n + 2[/tex]

Your question is not complete, it seems it is missing the following information below;

DVD rentals:         1    2    3    

Total DVD points:  3   5    7    

The number of points earned is a function of number of DVD rentals.

For the first DVD, the number of points earned;

[tex]n_1 = p_1 + c\\\\where;\\c \ is \ the \ constant \ point \ earned[/tex]

3 = 1 + c

3- 1 = c

2 = c

For nth week the total point earned is given as;

[tex]n_t_h = p_n + c\\\\n_t_h = p_n + 2[/tex]

Thus, for the nth week, the total points earned in the DVD rentals is [tex]p_n + 2[/tex]

Answer 2

Here we have a problem with arithmetic sequences.

After a small online search, I've found that:

Fantastik Flicks gives: 3 points for the first rental, 5 points for the second rental, 7 points for the third rental

And so on.

We will find that the total of points in the n-th week is given by:

Wₙ = 15 + (n - 1)*18

Looking at the number of points given for each rental, we can see that we have an arithmetic sequence with an increase of 2, 3, 5, 7, 9, 11, 13, 15,...

We want to find the total of points earned in each week. For example, for the first week the total of points is: W₁ = (3 + 5 + 7) = 15

For the second week, the total of points is: W₂ = (9 + 11 + 13) = 33

For the third week, the total number of points is: W₃ = (15 + 17 + 19)  = 51

Now let's see if Wₙ also is arithmetic. To see this, we need to look at the difference between consecutive elements of Wₙ.

W₂ - W₁ = 33 - 15 = 18

W₃ - W₂ = 51 - 33 = 18

So in both cases we got the same difference, this makes a lot of sense, taking in account that we construct the Wₙ with an arithmetic sequence, so is logical that the sequence {Wₙ} is also arithmetical.

Now that we know this, we can see that in the n-th week, the total of points will be: Wₙ = W₁ + (n - 1)*18Wₙ = 15 + (n - 1)*18

The slot size limit for Fish A is from 28 to 32 inches. The minimum size limit for Fish B is 11 inches. Write the ranges of Fish A and Fish B in interval notation and in set-builder notation. Does the range for the Fish B seem reasonable? Explain.

Answers

Notations are used to specify the range of a function. The range of fish A is [28,32] while the range of fish B is [11,infinity).

Also, the range of fish B is not reasonable.

For fish A, we have:

[tex]Minimum = 28[/tex]

[tex]Maximum = 32[/tex]

For Fish B, we have:

[tex]Minimum = 11[/tex]

For fish A, the minimum and the maximum are inclusive. So, the range is:

[tex]Range= [Minimum, Maximum][/tex]

This gives:

[tex]A = [28,32][/tex]

For fish B, the minimum is known (and inclusive). The maximum is not known, so we represent the maximum with infinity.

So, the range is:

[tex]Range= [Minimum, Maximum)[/tex]

[tex]B = [11,\infty)[/tex]

The range of fish B is not reasonable because there is a limit to the size of fish a slot can take.

Answers

Answer:

Step-by-step explanation:

Isolate the variable by dividing each side by factors that don't contain the variable.

s=5

Answer:

s = 5

Step-by-step explanation:

1.52(s + 3) − 2.61 = 9.55

solve the brackets first

1.52s + 4.56 − 2.61 = 9.55

1.52s + 1.95 = 9.55

1.52s = 9.55 -  1.95

1.52s = 7.6

s = 7.6 / 1.52

s = 5

Let's Cross-Check

1.52 (5 + 3) − 2.61

7.6 + 4.56  − 2.61

7.6  + 1.95

= 9.55

Answers

Answer:

4

Step-by-step explanation:

4 times 4 is 16. 7 less than 16 is 9.

Answer:

4

Step-by-step explanation:

You can use a simple formula for finding the answer to problems like these. You read it out and put your information in order and use a variable (such as x) in place of the number.

4 * x - 7 = 9

Then solve by getting your variable alone on one side.

Add 7 to both sides: 4 * x = 16

Divide both sides by 4: x = 4
