Answer:
f(1) = 4f(n) = f(n - 1) + 4Step-by-step explanation:
Given the sequence:
4, 8, 12, …The first term is 4 and common difference is 4
Recursive formula:
f(1) = 4f(n) = f(n - 1) + 4Determine whether or not the following graph represents two quantities that are proportional to each other. Explain your reasoning.
Answer:
The quantities are not proportional.
Step-by-step explanation:
The values, x and y, do not begin or pass through the origin, (0,0). This means they are not proportional.
The graph represents two quantities are not proportional to each other.
What is Proportional?A relationship is proportional if each pair of data values are related in the same way, by multiplying by a factor. You can recognize a proportional relationship by looking at data, an equation, or a graph.
Given:
As, A relationship is proportionate if its graph is a line or ray that passes through the origin.
and, It is not proportionate if the line or ray does not go through the origin. Additionally, if anything is not linear, it is not proportional.
Here the graph also does not pass through the origin.
Hence, the graph is not proportional.

An ice hockey puck is in the shape of a cylinder with a radius of 3.8 cm, and a thickness of 2.5 cm.
It is made out of rubber with a density of 1.5 grams per cm ³
Work out the mass of the ice hockey puck.
Give your answer correct to 3 significant figures.
The mass of the ice hockey puck with the below dimensions and density of 1.5 g/cm² is 170 grams.
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
A variable can either be dependent or independent. A dependent variable depend on other variable while an independent variable does not depend on other variables.
The volume of the puck = π * radius² * thickness = π * 3.8² * 2.5 = 113.4115 cm³
Density = mass / volume
1.5 = mass / 113.4115
mass = 170 g
The mass of the ice hockey puck with the below dimensions and density of 1.5 g/cm² is 170 grams.

A tree casts a shadow of 48ft. A man who is 6ft. tall casts a shadow of 4 ft. How tall is the tree?
Answer:
72ft.
Step-by-step explanation:
Could be mis-understanding the problem, but if the man is 6ft tall and having a 4ft shadow, then you want to figure out how many times 4 goes into 48, which signifies how many times taller the tree is compared to the man.
48/4= 12
next you want to multiply 6 by 12, which shows exactly how tall the tree is.
6x12= 72.
Answer:
72ft
Step-by-step explanation:
so you would divide 6 and 4 and that is 1.5
then you would do 48ft x 1.5 which is 72ft
so the tree is 72ft tall

In a sixth grade class at Lincoln Middle School, there are 3 boys for every 4 girls in the class.
Fill in the blank: The ratio of boys to girls in the class is __________.
If there are between 20 and 30 students in the class, what could be the actual number of boys and girls in the class?
Answer:
There are multiple possibilities. One is there are 12 boys, and 16 girls. 12+16= 28 which is between 20 and 30. That would be 12:16, which can be simplified to 3:4. There is also 9 boys, and 12 girls. that would be 9:12, which can be simplified to 3:4. Also, 9 + 12 = 21, which is between 20 and 30.

Which expression is equivalent to
1.5(x + 3) + 3.8(7x –2)? Be sure to show all
steps of simplifying after picking an answer choice.
4.5x – 8.8
12.3x + 1
28.1x – 3.1
28.1x + 1
explain why also!
Answer:
28.1x – 3.1
Step-by-step explanation:
1.5(x + 3) + 3.8(7x –2)
Open the parenthesis
= 1.5x + 4.5 + 26.6x - 7.6
Simplify
= 28.1x - 3.1
Therefore, the equivalent expression to 1.5(x + 3) + 3.8(7x –2 is 28.1x - 3.1
Evaluate f(x)= -6+12 when x= -3,x=0, and x=1.
When x= -3, f(x)= , when x=0,f(x)= , and when x=1,f(x)= .
Given :
A function, f(x) = -6 + 12
To Find :
The value of f(x) when x= -3, x= 0 and x=1.
Solution :
Given function is f(x) = -6 + 12 .
Simplifying above function, we get :
f(x) = 6
Now, the given function is independent of x.
So, for any value of x the the value of functions remains constant.
Hence, this is the required solution.

Drag the tiles to the boxes to form correct pairs.
Match each pair of lines to the correct description
parallel lines
EF and CD
perpendicular lines
GH and EF
neither parallel nor
perpendicular lines
AB and CD
When two lines intersect at 90° degrees angle, the lines are perpendicular to each other. Two perpendicular lines, their slope will give a product of -1
i.e. if the first's line slope is 5, then the second line's will be -1 ÷ 5 = -¹/₅
To find the slope of a line, we divide the vertical distance by the horizontal distance.
We'll use the trial and error method to find the right pairing
Let's start with A(3, 3) and B(12, 6)
Vertical distance =
Horizontal distance =
The slope AB = ³/₉ = ¹/₃
We want BC to have a slope -1 ÷ ¹/₃ = -3
Try C(16, -6); check the slope with B(12, 6)
Vertical distance =
Horizontal distance =
Slope of BC = -12 ÷ 4 = -3
The slope BC = -3 is the value we want so, tile 1 pair with tile 4
-------------------------------------------------------------------------------------------------------------
Let's do A(-10, 5) and B(12, 16)
Vertical distance = 16 - 5 = 11
Horizontal distance = 12 - -10 = 22
Slope AB = ¹¹/₂₂ = ¹/₂
The perpendicular slope would be -1 ÷ ¹/₂ = -2
Try C(18, 4) with B(12, 16)
Vertical distance = 16 - 4 = 12
Horizontal distance = 12 - 18 = -6
Slope BC = ¹²/₋₆ = -2
Slope BC and slope AB perpendicular, so tile 3 matches with tile 6
--------------------------------------------------------------------------------------------------------------
Let's try A(12, -14) and B(-16, 21)
Vertical distance = 21 - -14 = 35
Horizontal distance = -16 - 12 = -28
The slope AB = ³⁵/-₂₈ = ⁵/₋₄
We need the perpendicular slope to be -1 ÷ -⁵/₄ = ⁴/₅
Try C(-11, 25)
Vertical distance with B = 25 - 21 = 4
Horizontal distance with B = -11 - -16 = 5
The slope = ⁴/₅
Tile 7 matches tile 8
--------------------------------------------------------------------------------------------------------------
Take A(-12, -19) and B(20, 45)
Vertical distance = 45 - -19 = 64
Horizontal distance = 20 - -12 = 32
Slope AB = ⁶⁴/₃₂ = 2
We need the perpendicular slope to be -1 ÷ 2 = -¹/₂
We have C(6, 52) and checking the slope with B(20, 45)
Vertical distance = 45 - 52 = -7
Horizontal distance = 20 - 6 = 14
The slope is ⁻⁷/₁₄ = -¹/₂
Tile 9 pairs with tile 2
-----------------------------------------------------------------------------------------------------------
Conclusion
Tile 1 ⇒ Tile 4
Tile 3 ⇒ Tile 6
Tile 7 ⇒ Tile 8
Tile 9 ⇒ Tile 2
Tile 5 and Tile 10 do not have pairs
Answer:
Parallel lines = AB and CD
Neither parallel nor perpendicular lines = GH and EF
Perpendicular lines = EF and CD
