What is the correct order of the steps used to derive the identity?
A.) 4, 3, 5, 1, 2
B.) 4, 5, 3, 1, 2,
C.) 3, 4, 5, 1, 2
D.) 3, 4, 1, 5, 2
The correct order of the steps used to derive the identity is (A.) 4, 3, 5, 1, 2
How to determine the correct order of step?The trigonometry identity is given as:
tan(2x)
When the tangent formula is applied, we have:
[tex]\tan(2x) = \frac{\sin(2x)}{\cos(2x)}[/tex] --- step 4
Expand sin(2x) and cos(2x)
[tex]\tan(2x) = \frac{2\sin(x)\cos(x)}{\cos^(x) - \sin^2(x)}[/tex] --- step 3
The option from the list that obey the above order is (a) 4, 3, 5, 1, 2
Hence, the correct order of the steps used to derive the identity is (A.) 4, 3, 5, 1, 2

Which set of line segments could create a right triangle?
As we know in a right angled triangle the sum of two sides will always be greater than the third side.
We will use the Pythagoras Theorem here:
c² = a² + b²; where c is the longest side.
The only segments satisfying this are

Point Lis a centroid of the triangle FWD, If RL = 54 cm, what is RD?
O 81 cm
O 162 cm
O 100 cm
O 58 cm
Answer:
RD = 162 cm
Step-by-step explanation:
LD = 2 RL = 2* 54 = 108
RD = RL + LD
RD = 54 + 108
RD = 162 cm
The length of RD is 162 cm if Point L is a centroid of the triangle FWD, If RL = 54 cm option (B) is correct.
What is the triangle?In terms of geometry, the triangle is a three-sided polygon with three edges and three vertices. The triangle's interior angles add up to 180°.
We have:
Point L is a centroid of the triangle FWD, If RL = 54 cm
From the centroid definition:
LD = 2RL
LD = 2×54 = 108 cm
RD = RL + LD
RD = 54 + 108
RD = 162 cm
Thus, the length of RD is 162 cm if Point L is a centroid of the triangle FWD, If RL = 54 cm option (B) is correct.

Which two points should the line of best fit go through to best represent the data in the scatterplot?
Given : A graph with points (1, 3), (2, 7), (3, 8), (4, 11), (5, 12), (6, 13).
To find : From Which two points the line of best fit goes through
Solution:
(3, 8) & (5, 12) will be two points
as then line points will be
( 1 , 4 ) , ( 2, 6) , ( 3 , 8 ) , ( 4, 10) , (5 . 12) & ( 6 , 14)
(1, 3) will be below ( 1 , 4 )
(2 , 7) will be above ( 2 , 6)
( 3 , 8 ) will be on line
(4 , 11 ) will be above ( 4 , 10)
( 5 , 12 ) will be on line
( 6 , 13) will be below ( 6 , 14 )
(1, 3) & ( 6 , 13) two points are below line
(2 , 7) & (4 , 11 ) two points above line
Hence points are Equally scattered above & below line
Hence (3, 8) & (5, 12) will be two points on line of best fit
Hope it helpss !!

What is an Equation of a line?
The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept
And y - y₁ = m ( x - x₁ )
y = y-coordinate of second point
y₁ = y-coordinate of point one
m = slope
x = x-coordinate of second point
x₁ = x-coordinate of point one
The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )
Given data ,
Let the equation be A
Let the two points be A and B
where the point A is A ( x₁ , y₁ ) = A ( 2 , 7 )
The point B ( x₂ , y₂ ) = B ( 1 , 3 )
Now , the equation of line is given by
y - y₁ = m ( x - x₁ )
The slope of the line is m = ( y₂ - y₁ ) / ( x₂ - x₁ )
Substituting the values in the equation , we get
m = ( 7 - 3 ) / 2 - 1 )
m = 4
The equation of line is y - y₁ = m ( x - x₁ )
Substituting the values in the equation , we get
y - 7 = 4 ( x - 2 )
y - 7 = 4x - 8
y = 4x - 1
The equation of line is y = 4x - 1
So , the points which satisfies the line is A ( 2 , 7 ) and B ( 1 , 3 )

Tina has two rectangular playpens to keep her new pet dogs. The first rectangle has a width of 6 feet and a length of x - 4 feet. The second rectangle has a width of 8 feet and a length of x + 2 feet. What is the sum of the two perimeters?
Answer:
4x+24 ft.
Step-by-step explanation:
Perimeter of first rectangular playpen mentioned: 2(6+x-4), which can be simplified to 2(x+2) = 2x + 4.
Perimeter of second playpen mentioned: 2(8+x+2), which can be simplified to 2(x+10) = 2x+20.
Add these two together: 2x+4 + 2x+20 = 4x+24. Don't forget to add units: 4x+24 ft.

If ray ST bisects ∠RSU and m∠TSU=43°, find m∠RSU.
Answer: 86 degrees
Explanation:
Angle TSU is formed when we bisect angle RSU. Recall that bisect means to cut in half. So TSU is half of RSU. Put another way, RSU is twice that of TSU.
angle RSU = 2*(angle TSU)
angle RSU = 2*43
angle RSU = 86

What is Proportion?
The proportion formula is used to depict if two ratios or fractions are equal. The proportion formula can be given as a: b::c : d = a/b = c/d where a and d are the extreme terms and b and c are the mean terms.
Given data ,
The number of batch recipe calls for 1 / 2 lb of flour = 1 batch
And to calculate the number of batches , we use
The number of batch recipe calls for 1 lb of flour will be
1 / 2 lb of flours = 1 batch
Multiplying by 2 on both sides , we find the number of batches for 1 lb of flour
Therefore , 1 / 2 x 2 = 1 x 2
1 lb of flour = 2 batches
3 / 4 lb of flour is 1 x 3 / 4 = 2 x 3 / 4
= 3 / 2 batches
= 1.5 batches
1 / 4 lb of flour is 1 x 1 / 4 = 2 x 1 / 4
= 1 / 2 batches
= 0.5 batch
Hence , The number of batches that can be made with 1 lb , 3 / 4 lb and 1 / 4 lb are 2 batches , 1.5 batches and 0.5 batch respectively

Answer:
8 correct.
Step-by-step explanation:
80 / 100 = x / 40 (Since he got 80% INCORRECT you will subtract the value of x from 40)
100x = 80 x 40
x = 3200 / 100
