16. Rylan claimed that adjacent angles are complementary.
Draw an example that supports Rylan's statement and draw a
counterexample that shows her statement is not always true.
Answers
The example of adjacent angles that are complementary and those that are non-complementary are given as attached.
What are adjacent and Non-Adjacent angles?When two adjacent angles have a similar vertex and side, they might be complementary or supplementary angles.
If the total of neighboring angles equals 90 degrees, then they are complementary. If the total of neighboring angles equals 180 degrees, they are complementary to one another.
Non-adjacent Complementary Angles: Two angles that are not next to each other are non-adjacent complementary angles. AOB and XOY are non-adjacent angles since they share neither a vertex nor an arm. They also add up to 90°. As a result, these two angles are non-adjacent complimentary.

A constraint is a restriction or limitation on the possible solutions of a problem or system. In the context of a system of inequalities, a constraint is an inequality that must be satisfied by any solution of the system. A system of inequalities is a set of multiple inequalities that must all be satisfied simultaneously. Solving a system of inequalities involves finding the set of all possible solutions that satisfy all of the constraints. This can be done graphically by graphing the inequalities and finding the intersection of their solution sets, or algebraically by isolating the variables and solving for their values.
WILL MARK BRAINLIEST!! function g is the result of these transformations on the parent sine function: •vertically stretch by a factor of 3 •horizontal shift left pi/2 units • vertical shift down 4 units. Substitute the values of A, C, and D to complete the equation modeling function g
Answers
By substituting the values of A, C, and D, the equation modelling the function is g(x) = 3·sin(x - π/2) - 4.
From the question, we have the following information;
The vertical distance of the sine function = 3 × The parent function
∴ A = 3
Given that the horizontal shift left = π/2 units (from an online source with a similar question)
The vertical shift down = 4 units
The given function g is g(x) = A·sin(x + C) + D
Where,
A is the amplitude = The maximum displacement from the rest or equilibrium position = 3
C is the horizontal shift = -π/2 (The negative sign is for the shifting to the left)
D is the vertical shift = -4 (The negative sign is for a shift in the downward direction)
Therefore, the equation modelling the function is g(x) = 3·sin(x - π/2) - 4.

Please help me with this. Rule: y= x-1/4 1/4 13/4 2
Answers
The values of y are 0, 3 and 7/4 respectively. The solution has been obtained by using the substitution method.
What is substitution method?
The substitution approach is one of the algebraic methods for resolving simultaneous linear equations. It entails swapping any variable to change its value from one equation to another. By doing this, two linear equations are merged into one straightforward equation with one variable.
We are given a rule which is that y= x-1/4
Various values of x are given
So, in order to find the values of y, we will use the substitution method.
When x=1/4, then
⇒y=1/4-1/4
⇒y=0
When x=13/4, then
⇒y=13/4-1/4
⇒y=12/4
⇒y=3
When x=2, then
⇒y=2-1/4
⇒y=8/4-1/4
⇒y=7/4
Hence, the values of y are 0, 3 and 7/4 respectively.

A)
House 1 value is an exponential function.
House 2 value is a linear function.
B)
House 1:
f(x) = 253,980 x
House 2:
f(x) = 256,000 + 7000x
C)
House 1 will have the greatest value.
The significant difference in the value of either house after 45 years is $168844
The value of house 1 after 45 years:
f(45) = $739844
The value of the house 2 after 45 years:
f(45) = $571000
What is a function?A function is a relationship between inputs where each input is related to exactly one output.
Example:
f(x) = 2x + 1
f(1) = 2 + 1 = 3
f(2) = 2 x 2 + 1 = 4 + 1 = 5
The outputs of the functions are 3 and 5
The inputs of the function are 1 and 2.
We have,
House 1:
The value of the hours is described by an exponential function.
There is an increase of 2% per year.
f(x) = 253,980 x [tex]1.02^x[/tex]
Where x is the number of years.
House 2:
The value of the hours is described by a linear function.
There is an increase of $7000 per year.
f(x) = 256,000 + 7000x
Where x is the number of years.
Now,
For x = 45,
f(45) = 253,980 x [tex]1.02^x[/tex]
f(45) = 253,980 x [tex]1.02^{45}[/tex]
f(45) = $739843.74
f(45) = $739844 ____(1)
f(x) = 256,000 + 7000x
f(45) = 256,000 + 7000 x 45
f(45) = 256,000 + 315000
f(45) = $571000 ______(2)
From (1) and (2),
House 1 will have the greatest value.
The significant difference in the value of either house after 45 years
= $739844 - $571000
= $168844
The value of house 1 after 45 years:
f(45) = $739844

Answers
For the given situation sentence represents amount of the sparkling water bought by Layla is given by :
Option A). Layla bought 20milliliters less sparkling water than 2 liters.
Sparkling water in each pack is equal to 330 milliliters
Number of packs of sparkling water bought by Layla is equal to 6 packs
Amount of sparkling water in 6 packs = 330 milliliters
⇒ Amount of sparkling water in 6 packs = ( 330 × 6 ) milliliters
⇒ Amount of sparkling water in 6 packs = ( 1980 ) milliliters
1 liter = 1000milliliters
⇒ 2 liter = 2000milliliters
1980 is less than 2 liters
Difference between 1980milliliters and 2 liters
2000 - 1980 = 20milliliters
Therefore, sentence which represents the given situation of sparkling water bought by Layla is option A) Sparkling water bought by Layla is 20ml less than 2L.

It is the shortest distance between two points in Euclidean space and it is represented by an equation in the form of y = mx + b, where m is the slope and b is the y-intercept.
As both destinations, A and B are measured as the crow flies, or in a straight line, and you are able to travel only in straight lines along the main directions (north, south, east, and west), it is possible that the path to point B includes more turns or obstacles, such as buildings or rivers, that require you to travel further in order to reach the destination.

A company is offering a bank account. The value, in dollars, of the account, is represented by the function A(t)=50,000(1.02)^t, where t represents the number of years since the account was first opened. Determine the average rate of change of the account value from t = 0 to t = 5. Express your answer in the nearest cent. PLS HELP!!!
Answers
The average rate of change of the account value from t = 0 to t = 5 is the change in the account value divided by the change in time, or (A(5) - A(0))/(5 - 0).
We can substitute the given function into the equation:
A(t) = 50,000(1.02)^t
So,
A(5) = 50,000(1.02)^5
and
A(0) = 50,000(1.02)^0
Now we can substitute these values in the equation of average rate of change:
(A(5) - A(0))/(5 - 0) = (50000(1.02)^5 - 50000(1.02)^0) / (5-0)
This simplifies to
(50000(1.02)^5 - 50000) / 5
Which is approximately equal to 67,622.05
So the average rate of change of the account value from t = 0 to t = 5 is approximately 67,622.05.
In triangle ABC. AD is a median. P and q are the midpoints of AB and AD respectively. If ar (ABC) = 72cm ^ 2 then ar (APQ) =?
Answers
The area of the ar (APQ) = 18 cm ^ 2 for the given triangle ABC.
Define the term median of triangle?A line segment from such a vertex here to middle of the other side is what is meant by a median. When the vertex is just an angle in a right triangle and the non-congruent angle about an isoceles triangle, it also functions as an angle bisector.Given that:
AD is ABC's median, ABC will be divided into two distinct triangles by AD.We are aware that a triangle's middle separates that into two triangles with equal areas. Triangle ABC's median is AD, and ABD's median is PQ.Then, area (ΔABD) = area (ΔADC)
And, area (ΔABD) = 1/2 area (ABC) eq.....(i)
Thus, In ΔABD, PQ is the median, as PQ are the mid points on AB and AD respectively.
Then,
ar (APQ) = 1/2 ar(ΔABD)
ar (APQ) = 1/2 × [1/2 ar(ABC)] ....... (Use eq (i))
ar (APQ) = 1/4 ar(ΔABC)
ar (APQ) = 1/4 *72 cm ^ 2
ar (APQ) = 18 cm ^ 2
Thus, the area of the ar (APQ) = 18 cm ^ 2 for the given triangle ABC.

Answer: x = 3
Step-by-step explanation:
Set the two equal to each other.
-5 (2x+1) = -35
-5 x 2x = -10x , -5 x 1 = -5
-10x -5 = -35
Add 5 to both sides.
-10x = -30
Divide both sides by -10.
x = 3

Answers
This triangle is an acute triangle because all three angles measure less than 90 degrees.
It is also a scalene triangle because all three sides have different lengths. I know this because an acute triangle is defined as a triangle where all three angles measure less than 90 degrees and a scalene triangle is defined as a triangle where all three sides have different lengths.
According to the lengths of sides, triangles can be classified into :
Scalene.
Isosceles.
Equilateral.
Different Types of Triangles Based on Angles are :
Acute-angled. Obtuse-angled. Right-angled.
