Parallel = lines with the same slope
Perpendicular = lines whose slopes are negative reciprocals (i.e. product is –1)
Step-by-step explanation:
The first part: circle b, c, d, f (1 ³/₄ is another way of saying ⁷/₄), and h (a horizontal line y = b has a slope of 0)
The second part: circle a, d (1 ⁴/₇ is another way of writing ¹¹/₇, the negative reciprocal of –⁷/₁₁), and e

A university has 40,140 students. In a random sample of 210 students, 14 speak three or more languages. Predict the number of students at the university who speak three or more languages.
Answers
Answer:
2676 students
Step-by-step explanation:
Total number of students =. 40,140
During study:
Sample size = 210
Number of samples who speak 3 or more languages = 14
Proportion who speak 3 or more languages :
14 / 210 = 0.0666666
Applying the proportion to the total. Population :
0.0666666 * total number of students
0.0666666 * 40140
= 2675.997324
= approximately 2676 students

Find the 14th term of the geometric sequence 2, 6, 18,
Answers
The geometric sequence is starting with 2 and multiplying by 3 every time. We can get the rule of this sequence by...
If 2 is a_0, 6 is a_1, 18 is a_2, etc.
a_n=2*3^n
For the 14th term, which is a_13, the value is 2*3^13.
Using a calculator because I'm too lazy to calculate 3^13 sorry, we can get.
3188646
The required 14th term will be 3188646 in the given geometric sequence.
What is geometric series?The geometric series defined as a series represents the sum of the terms in a finite or infinite geometric sequence. The successive terms in this series share a common ratio.
The nth term of a geometric progression is expressed as
Tₙ = arⁿ⁻¹
Where a is the first term, r is the common ratio
The geometric sequence is given in the question, as follows:
2, 6, 18,...
We have to determine the 14th term of the given geometric sequence.
As per the given geometric sequence,
The first term a = 2.
The common ratio r = 6/2 = 3
14th term = arⁿ⁻¹
Substitute the value of a = 10, r = -2, and n = 12 in the formula,
14th term = 2(3)¹⁴⁻¹
14th term = 2(3)¹³
14th term = 2(1594323)
14th term = 3188646
Thus, the required 14th term will be 3188646.

Show that the lines
y = 4x + 2 and 8x + 2y = -3 are parallel
help pls asap ty ! ! !
Answers
Answer:
They intersect
Step-by-step explanation:
We can determine from their equations whether two lines are parallel by comparing their slopes. If the slopes are the same and the y-intercepts are different, the lines are parallel. If the slopes are different, the lines are not parallel.
Here we have two functions:
1) y = 4x + 2
2) 8x + 2y = - 3
2y = - 8x - 3
// divide both sides by 2
y = - 4x - 1,5
- 4 ≠ 4 , so these lines aren't parallel, maybe you wrote the assignment incorrect (e. g. if there would be " - " before 8 in the second function, those lines would be parallel), here they intersect.

Part D

Part E
Khafre was a son of Khufu. He also had a pyramid built, but it was not as big as his father’s. The volume of the Pyramid of Khafre is about 2,115,072 cubic meters, and its height is about 136 meters. Approximate the length of each side of the base?

Part A: S^2= 3V/H
Part B: S =[tex]\sqrt{3\frac{v}{h} }[/tex]
Part C: s=√3* 2,433,400 /138=230 metres
Part D: This website says that the length of Khufu's Pyramid is about 230 meters. My calculation was correct.
Part E: S = √3*2,115,072/ 136 =216 metres
Part F: The length of Khafre's pyramid is about 215.5 My calculation was a little off, but not by much.
Part G: 14 meters longer
Step-by-step explanation:
Part A:
I am going to solve:
So,
V=1/3 [tex]HS^{2}[/tex]
Then, multiply both sides by 3:
V x 3= 1/3 [tex]HS^{2}[/tex] x 3
So,
3V=[tex]HS^{2}[/tex]
Then, we divide by H:
[tex]\frac{3V}{H}[/tex]=[tex]\frac{HSs^{2} }{H}[/tex]
So,
[tex]\frac{3V}{H}[/tex]= [tex]s^{2}[/tex]
Then switch sides:
[tex]s^{2}[/tex]= [tex]\frac{3V}{H}[/tex]
