Determine whether each sequence is arithmetic. If so, identify the common difference and find the 32 nd term of the sequence. 7,10,13,16, . . . . .
Common difference = 3 , 32nd term = 100
The arithmetic sequence is the sequence where the common difference remains constant between any two successive terms.
The given series is
7, 10, 13, 16....
common difference = 10-7 = 13- 10= 16-13 = 3
Therefore there is a common difference between the two consecutive number.
In this series the common difference is 3.
Hence we get to know that the given series is an arithmetic series.
To identify the 32nd term we have a formula:
[tex]t_{n}[/tex] = a +(n-1)d
Here a = first number of the series
n = number of series
d = common difference
[tex]t_{32}[/tex] = 7 + (32-1)3
= 7 + 31×3
= 7 + 93
= 100
Hence the 32nd term is 100.

What is a math conjecture?
A mathematical assertion that hasn't been thoroughly proven is referred to as a conjecture. When one observes a pattern that holds true in numerous instances, hypotheses start to form. A pattern may be true in many instances, but that does not guarantee that it will be true in all instances.A rotation of 75° (because 30 + 45 = 75) should map △ABC to △A″B″C″. By using the

The Measurement of ∠6 i.e. m∠6 is 120°
What is measurement of an angle ?The measurement of angle if the degree of that angle or we can also say that the angles are always measured in degrees. In geometry, the complete one revolution of four quadrants is of 360 degrees (360°) and divided into total of 360 parts where each part of this represents a degree.
How to find angle measurement ?As stated above there are total 360 parts in one revolution thus thus we can find value of particular angle by subtracting the angle from 360.
In the question
as ∠7 is an alternate angle to 60 degree,
thus ∠7 = 60°
According to sum of angle property :
∠7 + ∠6 = 180
60 + ∠6 = 180
∠6 = 180-60 = 120
Thus m∠6 = 120°

Hill 1 or Hill 2 (circle/underline/pick one)
Explanation:
7. Is the roller coaster a function? Why or why not?
Function: YES or NO (circle/underline/pick one)
Explanation:
Using function concepts, it is found that:
3. Two ordered pairs are: (0, 0) and (130,260). The slope is of 2.
4. The equation of the line is of y = 2x.
5. The domain is 0 ≤ length ≤ 400, and the range is 0 ≤ height ≤ 260.
6. a)
For Hill 1, we have that:
The bottom point is (130,260).The top point is (170,60).For Hill 2, we have that:
The bottom point is (400,0).The top point is (360,80).6. b) The rate of change down Hill 1 is of -5, while it is of -2 for Hill 2.
6. c) Due to the higher rate of change, Hill 1 is steeper.
7) The roller coaster is not a function, as for lengths between 190 ft and 240 ft, there are vertically aligned points on the graph.
What are the two ordered pairs on the initial climb, what is the slope, and what is the equation of the line?Two ordered pairs are: (0, 0) and (130,260).
The slope is given by change in y divided by change in x, hence:
m = (260 - 0)/(130 - 0) = 2.
Considering the slope and the intercept(which is of 0, as when x = 0, y = 0), we have that:
The equation of the line is of y = 2x.
What are the domain and the range of the graph?The domain of a function is the set that contains all possible values of the input. In the graph, it is all the values assumed by the horizontal axis.The range of a function is the set that contains all possible values of the output. In the graph, it is all the values assumed by the vertical axis.Hence:
The domain is 0 ≤ length ≤ 400, and the range is 0 ≤ height ≤ 260.
Bottom and top of the hills:For Hill 1, we have that:
The bottom point is (130,260).The top point is (170,60).For Hill 2, we have that:
The bottom point is (400,0).The top point is (360,80).The rates of change(change in height divided by change in length) are given as follows:
Hill 1: (-200)/40 = -5.Hill 2: -80/40 = -2.Due to the higher rate of change, Hill 1 is steeper.
Is the graph a function?A graph is a function if it has no vertically aligned points, that is, each value of the input is mapped to only one value of the output.
Hence:
The roller coaster is not a function, as for lengths between 190 ft and 240 ft, there are vertically aligned points on the graph.

Find the equation of the line that is perpendicular to y=2x+8 and passes through the point (8, -8).
A. y = 2x + 12
B. y = 1/2x - 4
C. y = -1/2x - 4
D. y = -2x + 12
Answer:
c. y = -1/2x - 4
Answer:
C
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c (m is the slope and c the y- intercept )
y = 2x + 8 ← is in slope- intercept form
with slope m = 2
given a line with slope m then the slope of a line perpendicular to it is
[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{2}[/tex] , then
y = - [tex]\frac{1}{2}[/tex] x + c ← is the partial equation of the perpendicular line
to find c substitute (8, - 8 ) into the partial equation
- 8 = - 4 + c ⇒ c = - 8 + 4 = - 4
y = - [tex]\frac{1}{2}[/tex] x - 4 ← equation of perpendicular line

Is an elevation of -10 feet closer or farther from the surface of the ocean than an elevation of -8 feet?
The elevation of -10 feet is farther from the surface level of the ocean than an elevation of -8 feet.
Here, we are given two elevation levels from the surface of the ocean.
One elevation is of -10 feet and another one is of -8 feet.
An elevation of -10 feet implies that the distance from the surface level is 10 feet.
On the other hand an elevation of of -8 feet implies that the distance from surface level is 8 feet.
Thus, by comparing the distances, we can see that elevation of -10 feet is farther from the surface level of the ocean than an elevation of -8 feet. To be more precise, it is 2(10-2) feet farther than an elevation of -8 feet.

1 mile is equivalent to 1.609 kilometers. Both the mile and the kilometer are units of measurement. A mile is longer than a kilometer, nevertheless. A larger unit is a "mile."
1000 meters make up one kilometer. We use kilometers to calculate distance when traveling between two points.

The 10th term of an arithmetic sequence is found to be a₁₀ = 115.
What is the sequence of AP arithmetic progression?In Arithmetic Progression, the difference between two mathematical orders is a constant quantity (AP). Arithmetic Sequence is another name for it.
We'd come across a few specific terms in AP that had been labeled as:
The first term (a)Common difference (d)Term nth (an)The total of first n terms (Sn)As shown below, the AP can also be viewed in analysed in terms of common differences.
The following is the procedure for evaluating an AP's n-th term: an = a + (n − 1) × dThe arithmetic progression sum is as follows: Sn = n/2[2a + (n − 1) × d].Common difference 'd' of an AP: d = a2 - a1 = a3 - a2 = a4 - a3 = ...... = an - an-1.Now, as per the given question;
Let the 9th term be 'a₉' = 132.
The 11th term be 'a₁₁' = 98.
The 10th term be 'a₁₀'.
The AP must have contain equal common difference. So,
d = a₁₀ - a₉
d = a₁₀ - 132
And, also
d = a₁₁ - a₁₀
d = 98 - a₁₀
Since, a₁₀ - a₉ = a₁₁ - a₁₀ for forming an AP.
Equate the common difference.
a₁₀ - 132 = 98 - a₁₀
Bring the variable part on single side.
2a₁₀ = 98 + 132
2a₁₀ = 230
a₁₀ = 115.
Therefore, the value of the 10 th term is estimated as a₁₀ = 115.

Determine whether each series is arithmetic or geometric. Then evaluate the finite series for the specified term number. 2+7+12+ . . . . . . ; n=8
The given series is an arithmetic series. The sum of its first 8 terms is 156.
To determine whether the series is an arithmetic or geometric one, we need to check how the consecutive terms relate to each other.
If it is an arithmetic series, then:
a(n) = a(n-1) + d
where d is the common difference.
If it is a geometric series, then:
a(n) = a(n-1) . r
where d is the common ratio.
The given series is:
2+7+12+ . . . .
and the number of terms is 8.
In the given series:
a(1) = 2
a(2) = 7
a(3) = 12
Notice that the difference is constant,
d = a(3) - a(2) = a(2) - a(1)
= 7 - 2 = 5
Sum formula for the first n term of an arithmetic series is:
S(n) = n/2 . [2a(1) + (n - 1) . d]
Substitute n = 8, a(1) = 2, and d = 5
S(8) = 8/2 ( 2.(2) + (8 -1) .5)
S(8) = 4. 39 = 156

Step-by-step explanation:
I think you meant
-0.4 - x = -6(x - 3.1) + 6x
-0.4 - x = -6x + 6x + 18.6
-0.4 - x = 18.6
-x = 18.6 + 0.4
-x/-1 = 19/-1
x = -19

- substitution method.
The given system of equation is:
-2x + 8y = -8 ....... (1)
5x - 8y = 20 ........(2)
Notice that in the both equations the coefficients of y are -8 and 8, hence if we add those coefficients, they will be cancelled out.
Therefore, we will choose elimination method.
Add equation (1) and equation (2)
-2x + 8y = -8
5x - 8y = 20 +
3x = 12
x = 12/3 = 4
Substitute x = 4 into equation (1):
