[1/2, sqrt(3)/2] and [-1/2, -sqrt(3)/2] are the unit vectors that are parallel to the tangent line to the curve.
Explain what a unit vector is?
A quantity with both magnitude and direction is referred to as a vector. A unit vector is one with a magnitude of 1. It also goes by the name Direction Vector.y=2sin(x)
dy/dx equals 2 cos x at pi/6 for x.
pi/6 = 2 cos pi/6 = 2 sqrt(3)/2 = sqrt = dy/dx(pi/6) (3)
the line sqrt(3) (x-pi/6) is the tangent to y at pi/6.
Atan Theta = sqrt is the angle with the x axis (3)
θ = pi/3 radians at 60 degrees
the vectors of units at (pi/6,1) [cos(60), sin(60)] and [-cos(60), -sin(60)] are parallel to this line.

New, larger bottle of shampoo contains 20 ounces. the bottle says you get 33% more than the amount in the original bottle. how many ounces of shampoo were in the original bottle?
Amount of shampoo in the original bottle is 15.0376 ounces.
Larger bottle of shampoo contains = 20 ounces
Let, amount of shampoo in the original bottle = x ounces
33% of amount of shampoo in the original bottle = ((33x)/100)
According to the question, amount of shampoo in the larger bottle is 33% more of amount of shampoo in the original bottle. So, mathematically we can write
20 = x + ((33x)/100)
⇒ 20 = x + 0.33x
⇒ 20 = 1.33 x
⇒ x = 20/1.33
⇒ x = 15.0376
Amount of shampoo in the original bottle is 15.0376 ounces.

The mean of samples 10, 10, 10, 10, 10, and 16 will be 11.
What is Mean?The mean is the straightforward meaning of the normal of a lot of numbers. In measurements, one of the markers of focal propensity is the mean. The normal is alluded to as the number-crunching mean. It's the proportion of the number of genuine perceptions to the absolute number of perceptions.
In a sample of n = 6, five individuals all have scores of x = 10 and the sixth person has a score of x = 16.
Then the data set will be given below.
10, 10, 10, 10, 10, 16
Then the mean of the data set will be
Mean = (10 + 10 + 10 + 10 + 10 + 16) / 6

Choose 5 ordered pairs whose second component is the opposite of the first component.
The 5 ordered pairs whose second component is the opposite of the first component are (-1,1), (-2,2), (-3,3), (-4,4) and (-5, 5).
Ordered pairs:
An ordered pairs is a composition of the x coordinate and the y coordinate (ordinate), having two values written in a fixed order within parentheses.
It can be written as (a,b).
Here
a represents the x coordinate and
b represents the y coordinate.
It helps to locate a point on the Cartesian plane for better visual comprehension.
Given:
The second component is the opposite of the first component.
Here we need to find the 5 ordered pairs for that.
For the given statement,
Let x be the first component and y be the second component.
So it can be written as,
=> y = -x
So, the five ordered pairs are,
=> 1 = -1
=>2 = -2
=> 3 = -3
=> 4 = -4
=> 5 = -5
So, the ordered pairs are,
(x,y) => (-1,1), (-2,2), (-3,3), (-4,4) and (-5, 5).

Mel should make 12 bracelets.
Here, we are given that Mel makes arm bracelets.
She is making a bracelet for each arm of her 6 friends.
We know that a humans by default have 2 arms each.
We will assume that all of her 6 friends have 2 arms each.
Thus, 6 of her friends will get 2 bracelets each, one for each arm.
This means that the total number of bracelets Mel should make will be given by-
2 + 2 + 2 + 2 + 2 + 2

Using the red arrows on the number line, you can tell which one is bigger or less. The dot is colored in so it has to have a line under it. So for the first one (top, left), The red arrow is pointing to the right side meaning x is bigger than 3. Therefore x ≥ 3.
In the next one (top, right) the arrow is pointing to the negative side so that one must be less than 3. The dot is also colored in meaning it is: x ≤ 3
In the next one (bottom, left) the arrow is pointing to the right, the dot not colored in, so it has no line. Therefore it is x > 3
Last one (bottom right) the arrow is pointing left, dot is white meaning that the answer is x < 3

What is the side length of a square with an area of 121 square centimeters?
In centimeters
The answer to this question is:
Size of a square's side = 11 cm
A Square is a flat geometric shape with four right angles and equal sides. The square's four sides are equal to one another or congruent. The square's opposing sides run parallel to one another. The square's diagonals form a 90° angle with one another. The two diagonals of the square are equivalent to one another. The square is made up of four vertices and four sides.
Area of square = ( Side )²
Given that:
Area of square = ( Side )² = 121 cm²
Dimensions of a square's side = √ Area
so, the length of the square's side = √ 121
= √ 11*11
= √ ( 11 )²
= 11
Thus, side of the square = 11 cm

Which of the following inequalities would be graphed with an open circle?
3(x - 2) < 18 and h + 6 > -3h + 12 would be graphed with an open circle.
Open circle is a term used for numbers that are less than (<) or greater than (>). On the other hand, Closed circle is used for numbers that are less than or equal to (≤ ) and greater than or equal to (≥).
Here, we are given four inequalities, let us check them one by one-
A. h + 6 > -3h + 12
⇒ 4h > 6
or h > 3/2
Here, we see that there is no equality sign, this means that 3/2 won't be included and hence h + 6 > -3h + 12 would be an open circle inequality.
B. 7 ≥ d/3
⇒ d ≤ 21
Here, we can clearly see the equality sign which means that 21 will be included. Hence, 7 ≥ d/3 would not be graphed with an open circle.
C. 3(x - 2) < 18
x - 2 < 6
x < 8
Here, we see that there is no equality sign, this means that 8 won't be included and hence 3(x - 2) < 18 would be graphed with an open circle.
D. 2y ≤ 14
y ≤ 7
Here, we can clearly see the equality sign which means that 7 will be included. Hence, 2y ≤ 14 would not be graphed with an open circle.
Thus, 3(x - 2) < 18 and h + 6 > -3h + 12 would be graphed with an open circle.

There is enough information to prove that triangles tno and gcm are congruent. true false
False, there is not enough information provided to Prove that both the triangles are congruent.
What is the congruent triangle?
Triangles have three sides and three angles, as we discovered in pre-algebra. We also discovered that a triangle's total angle is 180 degrees.
Congruent triangles are two triangles that are the same size and shape. Two congruent triangles remain congruent even if we flip, turn, or rotate one of them.
Two triangles must have the same angles and, as a result, must be congruent if their sides are the same. If two triangles are congruent or not, we may determine this simply by looking at their sides.
These two triangles are also equivalent if we know that two sides of one triangle and the angle between them are congruent to two sides and the angle between them of another triangle.
If we know that two angles and the side between them in one triangle are congruent with two angles and the side between them in another triangle, then these two triangles are probably congruent.
When two angles and a non-included side in one triangle are congruent to the corresponding angles and side of another triangle, we are left with the final scenario that results in congruent triangles.
The given data doesn't satisfy any of the conditions.
Hence, there is not enough information provided to Prove that the two triangles are congruent.

How do I find the value of x that make lines u and v parallel
=======================================================
Explanation:
The square marker in the top left corner tells us we have a 90 degree angle. The 8x+10 must also be 90 degrees for lines u and v to be parallel. Refer to the alternate exterior angle theorem. Ignore the diagonal lines. Your teacher likely put them there as a distraction.
