The order of decreasing water solubility for the given amines is NH2 B > II > III > I. Option B is the correct option.
When it comes to water solubility, the most important factor is the ability of a compound to form hydrogen bonds with water molecules. In the case of amines, the presence of a lone pair of electrons on the nitrogen atom allows for the formation of hydrogen bonds with water molecules.
Looking at the given amines, we can see that amine B (NH2) has the potential to form two hydrogen bonds with water, making it the most soluble amine.
Between amines I, II, and III, we can observe that amine II has two methyl groups, which reduce its polarity and ability to form hydrogen bonds with water molecules.
This makes it less soluble than amine B but more soluble than amine I. Amine I has a long carbon chain, which further reduces its polarity and ability to form hydrogen bonds, making it the least water-soluble amine of the three. Option B is the correct option.

What is circle ?
A circle is a two-dimensional geometric shape defined as the set of all points that are a fixed distance, called the radius, from a central point, called the center. A circle is the set of all points in a plane that are at a given distance from a given point, the center.
The area of a circle is given by the formula A = [tex]\pi r^{2}[/tex], where r is the radius of the circle. To find the area of a circle with a diameter of 5 m, we first need to find the radius. We can do this by dividing the diameter by 2:
r = 5 m / 2 = 2.5 m
Then we can substitute this value of r into the formula for the area of a circle:
A = [tex]\pi r^{2}[/tex] = π(2.5 m)^2 = 3.14 * 6.25 m^2 = 19.63 m²
So the area of a circle with a diameter of 5 m is 19.63 m², rounded to the nearest tenth, it would be 19.6 m². So the answer is c. 19.6 m².

How to find the image of a given set of points by rigid transformations
In this problem we find three points: A(x, y) = (- 2, 8), B(x, y) = (2, 4) and C(x, y) = (- 2, 6), whose images must be determined by means of rigid transformations, that is, transformations that modify a points without any alteration on Euclidean distances.
The transformation rule of this question is a combination of reflection about x-axis, dilation, horizontal and vertical translations, all of them rigid transformations. Now we determine the image of each point:
Point A
A'(x, y) = (- 0.5 · (- 2) + 3, - 0.5 · 8 + 3)
A'(x, y) = (1 + 3, - 4 + 3)
A'(x, y) = (4, - 1)
Point B
B'(x, y) = (- 0.5 · 2 + 3, - 0.5 · 5 + 3)
B'(x, y) = (- 1 + 3, - 2.5 + 3)
B'(x, y) = (2, 0.5)
Point C
C'(x, y) = (- 0.5 · (- 2) + 3, - 0.5 · 6 + 3)
C'(x, y) = (1 + 3, - 3 + 3)

A lighthouse sits at the edge of a cliff, as shown. A ship at sea level is meters from the base of the cliff. The angle of elevation from sea level to the base of the lighthouse is . The angle of elevation from sea level to the top of the lighthouse is . Find the height of the lighthouse from the top of the cliff. Do not round any intermediate computations. Round your answer to the nearest tenth. Note that the figure below is not drawn to scale.
There is no numbers provided, but this is how you solve it.
We can use the tangent function to solve for the height of the lighthouse.
Let h be the height of the lighthouse from the top of the cliff.
tan(angle of elevation from sea level to the top of the lighthouse) = (h+ height of lighthouse from sea level ) / distance from the base of the cliff
tan( angle of elevation from sea level to the top of the lighthouse) = (h+x) / distance from the base of the cliff
tan(angle of elevation from sea level to the base of the lighthouse) = (h) / distance from the base of the cliff
By dividing the first equation by the second equation
(h+x) / distance from the base of the cliff = tan( angle of elevation from sea level to the top of the lighthouse) / tan( angle of elevation from sea level to the base of the lighthouse)
(h+x) = (h) * (tan( angle of elevation from sea level to the top of the lighthouse) / tan( angle of elevation from sea level to the base of the lighthouse))
h = (x * tan( angle of elevation from sea level to the base of the lighthouse)) / ( tan( angle of elevation from sea level to the top of the lighthouse) - tan( angle of elevation from sea level to the base of the lighthouse))
After plugging in the values into the equation, we get:
h = (x * tan( )) / ( tan( ) - tan( ))
Round to the nearest tenth
h = (x * tan( )) /
How do you find the perpendicular bisector of a line segment?
The perpendicular bisector can be found by solving for the equation of the line and substituting the two points.
The perpendicular bisector of a line segment can be found by using the midpoint formula. The midpoint formula is used to find the midpoint of two points (x1,y1) and (x2,y2). The formula is:
Midpoint = (x1 + x2)/2, (y1 + y2)/2
Once the midpoint is found, the slope of the perpendicular line is found by using the negative reciprocal of the original line. The formula for the slope of the perpendicular line is y = -1/m * x + b, where m is the slope of the original line.
The equation of the perpendicular bisector is then found by substituting the slope and the midpoint into the equation of a line, y - y1 = m(x - x1).
Finally, the perpendicular bisector can be found by solving for the equation of the line and substituting the two points. The resulting equation is the equation of the perpendicular bisector.

What is the factor theorem formula?
The Factor Theorem states that if a polynomial P(x) has a factor (x-a), then P(a) = 0. In other words, if x-a is a factor of the polynomial, then the value of the polynomial when x=a is equal to zero.
The factor theorem is a fundamental concept in algebra and polynomial functions. This can be useful for determining the roots of a polynomial equation.
Key points:
The factor theorem only applies to polynomials, not other types of functions.The factor (x-a) must be a factor of the polynomial, not just a term.The value of P(a) will be zero only if x-a is a factor of the polynomial, not if it is just a root.The factor theorem can be used to find the roots of a polynomial equation by setting P(x) = 0 and solving for x.The factor theorem is closely related to the remainder theorem, which states that if P(x) is divided by (x-a), the remainder is P(a).In summary, The Factor Theorem is a fundamental concept in Algebra and Polynomials, it helps us understand the relationship between the roots and the factors of a polynomial equation and how a root of a polynomial is related to the value of the polynomial evaluated at that point.

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 )
given
x - 5y = 8 ( subtract x from both sides )
- 5y = - x + 8 ( divide through by - 5 )
y = [tex]\frac{1}{5}[/tex] x - [tex]\frac{8}{5}[/tex] ← in slope- intercept form
with slope m = [tex]\frac{1}{5}[/tex]
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}{\frac{1}{5} }[/tex] = - 5 , then
y = - 5x + c ← is the partial equation

In how many ways can 345 be written as the sum of an increasing sequence of two or more consecutive positive integers
There are 7 ways for 345 to be written as the sum of an increasing sequence of two or more consecutive positive integers.
We need to find consecutive numbers (an arithmetic sequence that increases by 1) that sum to 345. This calls for the sum of an arithmetic sequence given that the first term is k, the last term is g, and with n elements, which is:
n(k+g)/2.
There are 7 ways can 345 be written as the sum of an increasing sequence of two or more consecutive positive integers.
We look for sequences of n consecutive numbers starting at k and ending at k + n − 1. We can now substitute g with k+n- 1. Now we substitute our new value of g into n(k + g)/2 to get the sum i.e.
n(k+k+n-1)/2 = 345
This simplifies to n(2k+n-1)/2 = 345.
This gives a nice equation. We multiply out the 2 to get that n. (2k+n-1): =690. This leaves us with 2 integers that multiply to 690 which leads us to think of factors of 690.
We know the factors of 690 are:
