Sequences and series
===========================================================
Explanation:
The sequence is not arithmetic because the distance between adjacent terms keeps increasing. For instance, the gap from 0.4 to 1.6 is 1.6-0.4 = 1.2, while the gap from 1.6 to 6.4 is 6.4-1.6 = 4.8. There is no common difference, so we can rule out choices A and B.
To check if we have a geometric sequence, divide each term by its previous term
(term2)/(term1) = (1.6)/(0.4) = 4
(term3)/(term2) = (6.4)/(1.6) = 4
(term4)/(term3) = (25.6)/(6.4) = 4
Each time we get 4 as a result, so this sequence is geometric and the common ratio is r = 4.
Put another way: each new term is found by multiplying the previous term by 4.
0.4*4 = 1.6
1.6*4 = 6.4
6.4*4 = 25.6
This all leads to D being the answer.
Side note: the nth term of this geometric sequence is [tex]a_n = 0.4*(4)^{n-1}[/tex] where n is a positive integer and starts at n = 1.

B. The number of vertices equal the number of isosceles triangles.
Step-by-step explanation:
1st figure:
No. of vertices: 4
No. of isosceles triangles: 4
2nd figure:
No. of vertices: 5
No. of isosceles triangles: 5
3rd figure:
No. of vertices: 6
No. of isosceles triangles: 6
Thus, the number of vertices equal to the number of isosceles triangles.

Do anybody know how to do this ? This typa work is unnecessary bruh I hate school !
Man, I have to be honest with you, I have no clue. But here is something else though. I had to take Geometry last year, and you are right. It does suck. But, you will get through it! There is a light at the end of the tunnel and you will get it! Keep up the good work!
Answer:
m<1 = 87
Step-by-step explanation:
Bro I got you! You ain't gotta hate school no more!
Right the equation like this
m<1 + m<2 = <TSV (plug in)
m<1 + 65 = 152 (subtract 65 from 152 to get m<1)
m<1 = 87
There you go!
Hope this helps ya!

A pet store has 115 fish that need to be placed into fish tanks. Each tank hold 6 fish. How many tanks does the store for the fish
Answer:
19.1, rounded= 19
Step-by-step explanation:
115 divided by 6 = 19.1
Answer:
20 tanks
Step-by-step explanation:
Number of tanks = Total fish ÷ Number of fish that a tank can hold
= 115 ÷ 6
= 19 [tex]\frac{1}{6}[/tex]
= 20 tanks
Side Panel Expand side panel 7.01 Discussion: Sequences and Modeling with Functions Think about Pascal's triangle. Many numerical sequences exist in this triangle. Research/explore the triangle. Give an explicit or recursive rule or explanation for the sequence you found. For example, the sum of the diagonals gives the Fibonacci sequence. Give an example of where in the triangle your sequence is located.
Answer:
The sum of the triangle gives us the Fibonacci sequence. The sequence starts with 0 and 1, then adds along the road, such as 3+5=8, and 5+8=13.
It's a pattern going along while adding sequences together.

I am selling raffle tickets. It cost $155 to print the tickets and I want to make at least a $2,500 profit how much money do I need to raise to cover the cost of the printing and meet my goal
Answer:
Step-by-step explanation:
You need $2500 plus the amount to print the tickets. So 2500+155= $2655.
$155 will break even and then the $2500 will be the profit.

Taylor is checking her bank statement for the month of November. She began the month with $175 in her account. She made two deposits for $100 each and also made two withdrawals was for $55. Write an addition expression to represent this situation.
Answer:
The addition expression that represents the situation is;
175 + 100 + 100 - 55 -55
Step-by-step explanation:
Here, we want to write an addition expression to represent the situation
While the deposits are considered positive, the withdrawals are considered negative
So the addition expression will be;
175 + 100 + 100 - 55 - 55

Determine if the point (5, 7) is on the line of
Equation 5x + 6y = 67
Answer: The point (5,7) is on the line 5x+6y = 67
=====================================================
Explanation:
(5,7) means x = 5 and y = 7 pair up
Plug in those values to get...
5x + 6y = 67
5*5 + 6*7 = 67
25 + 42 = 67
67 = 67
We get the same number on both sides after fully simplifying. This means the equation is true. A true equation in the last step means the first equation is true when (x,y) = (5,7).
Therefore, the point (5,7) is a solution and it is on the line 5x+6y = 67.

which of the following is the slope intercept form of the equation of this line
Answer:
The slope-intercept form of the equation of this line is:
[tex]y=-x[/tex]
Hence, option 'c' is true.
Step-by-step explanation:
From the line equation, let us take two points
(1, -1)(-1, 1)Finding the slope between two points
[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]\left(x_1,\:y_1\right)=\left(1,\:-1\right),\:\left(x_2,\:y_2\right)=\left(-1,\:1\right)[/tex]
[tex]m=\frac{1-\left(-1\right)}{-1-1}[/tex]
[tex]m=-1[/tex]
From the line graph, we can determine the y-intercept by setting x=0 and checking the y-value at x=0
at x=0, y=0
Thus, (0, 0) is the y-intercept
We know that the slope-intercept form of the line equation is
y=mx+b
where
m=slope b=y-interceptAs we have already determined m=-1 and y-intercept=b=0
so substituting m=-1, b=0 in the slope-intercept form of the line equation
[tex]y=mx+b[/tex]
[tex]y=(-1)x+0[/tex]
[tex]y=-x[/tex]
Thus, the slope-intercept form of the equation of this line is:
[tex]y=-x[/tex]
Hence, option 'c' is true.

4 3/8-(-5 7/8)=
Answer:
10 1/4
Step-by-step explanation:
okay so the equation 4 3/8-(-5 7/8) needs to be simplified to a answerable equation by changing -(-5 7/8) to + 5 7/8
the reason for this is because when two subtraction signs are like this -(- it turns the number into a positive and we add instead of subtract.
4 3/8 + 5 7/8 = 9 10/8 = 10 2/8 = 10 1/4
I hope this helps you
