complementary means if two angles are added up they will equal 90. we and eliminate d cause 23.28+23.28=46.56 so d is wrong now let's try c 46.56+23.28=69.84 so c is wrong cause it doesn't equal 90 now let's try a 156.72+23.28=180 its wrong since we are using complementary angles instead of supplementary angles Supplementary are angle two angles that add up to 180. so that just leaves b cause 23.28+66.72=90. i hope this helps and i made sure to explain it as best as i can have a great day
The solution is Option B.
The measure of the complementary angles are 66.72° and 23.28°
What are Complementary Angles?When the sum of two angles is equal to 90 degrees, they are called complementary angles. For example, 30 degrees and 60 degrees are complementary angles.
Let the first angle and second angle be a and b respectively such that
a + b = 90°
Given data ,
Let the first angle be represented as A
Now , the value of A is = 23.28°
Let the second angle be represented as B
Now , the value of B is = B
The angles A and B are complementary ,
So , A + B = 90° be equation (1)
Substituting the values in the equation , we get
23.28° + B = 90°
On simplifying the equation , we get
Subtracting 23.28° on both sides of the equation , we get
B = 90° - 23.28°
B = 66.72°
Therefore , the value of B is 66.72°
Hence , the measure of the angle is 66.72°

An equation that shows the proportional relationship between cups (c) and tablespoons (n) is: B. c = 0.0625n
What is a proportion?A proportion is an equation which is typically used to indicate the equality of two (2) ratios. Therefore, proportions can be used in mathematics to show that two (2) ratios are equivalent and then used to calculate or determine all of the unknown quantities.
Mathematically, a proportional relationship can be represented by the following equation:
y = kx
Where:
y and x represent the variables in a proportional relationship.k is the constant of proportionality.Let the cups be represented by c.
Let the tablespoons be represented by n.
Next, we would determine the constant of proportionality (k) as follows:
c = kn
Making k the subject of formula, we have:
k = c/n
k = 0.5/8 ≡ 1.5/24
k = 0.0625.
Substituting the parameters into the equation for a proportional relationship, we have;
c = kn

which one of these constructiond would construct a line of relection that takes the point A to point B
Option D is the constructions that would construct a line of reflection from point A to point B. Make a line parallel to line AB.
A line parallel to line AB will generate a line of reflection that connects points A and B because a parallel line never intersects, resulting in direct imagery of Line AB.
What is a Parallel lines?Parallel lines are two lines in the same plane that are equal distance apart and never intersect. They can be both horizontal and vertical in orientation.
We have,
-Make a perpendicular bisector of segment AB.
A perpendicular bisector does not create a line of reflection that connects points A and B, but rather divides the line AB into two equal parts.
-Draw a line through B that is perpendicular to segment AB.
A perpendicular line through B to segment AB WILL NOT Make a line of reflection from point A to point B.
-Build the line that connects A and B.
A line passing through A and B will NOT create a line of reflection that connects points A and B, but will instead create Line A and B and not its reflection.
Hence,
Make a line parallel to line AB.
A line parallel to line AB will generate a line of reflection that connects points A and B because a parallel line never intersects, resulting in direct imagery of Line AB.

Step-by-step explanation:
given the system y=-1/2x-1 and -1/4x+y+4=0 write the solution to the system on the space provided below as an ordered pair
The solution to the system of equations as an ordered pair is (4, -3).
We are given a system of linear equations in two variables. The first equation is y = (-1/2)x-1. The second equation is (-1/4)x+y+4 = 0.
We need to find the solution of the system of equations. We will use the substitution method to solve for the values of "x" and "y".
y = (-1/2)x - 1
(-1/4)x + y + 4 = 0
Substitute the value of "y" from the first equation into the second equation.
(-1/4)x + (-1/2)x - 1 + 4 = 0
(-3/4)x+3 = 0
(3/4)x = 3
x = 4
Substitute the value of "x" back into the first equation to get the value of "y".
y = (-1/2)x - 1
y = (-1/2)4 - 1
y = -2 - 1

The value of n for a line that passes through point A(n, 4) and point B(6, 8) and is parallel to y = 2x - 5 is 6.
What is a parallel line?No matter how far we extend a parallel line, it will always remain straight. Take a look at the parallel lines in the following illustration. Lines "p" and "q" are parallel to each other as are lines "a" and "b."
We know that parallel lines have same slope, so the slope of y = 2x - 5 is 2 according the y intercept form, y = mx + b
Now using the point-slope form we will find the line parallel to Point B (6, 8)
y − y₁ = m(x − x₁)
Put m as 2, y₁ as 8 and x₁ as 6, and we wil get
y − 8 = 2(x −6)
y = 2x − 4 or
2 = (y + 4)/x (slope)
We will us point-slope form for point A(n, 4) too
y − 4 = 2(x −n)
y = 2x − 2n + 8 or
2 = (y - 8 + 2n)/x
As slope 2 is same in both points it means their equations are same too
(y + 4)/x = (y - 8 + 2n)/x
Lest solve for n
(y + 4)/x = (y - 8 + 2n)/x
y + 4 = y - 8 + 2n
4 = - 8 + 2n
4 + 8 = 2n
2n = 12
n = 12/2
n = 6
Thus, the value of n for a line that passes through point A(n, 4) and point B(6, 8) and is parallel to y = 2x - 5 is 6.

With the exponent 3 we get:
i³ = √(-1)³ = √(-1)²*√(-1) = -1*i = -i
i³ = -i
Finally, the exponent 4 gives:

What is a vertical angle?
When two lines intersect, the angles that face each other are called vertical angles.Instead of referring to them as being up-down, "vertical" in this context denotes that they share a vertex (corner point).Assuming that C and D constitute vertical angles
The formula is C = (-3x) + 58 and D = x - 2.
We must ascertain what D's measurement is.
Vertical angles are really a pair of opposing angles created when two lines cross.
A and B in the figure represent vertical angles. C and D are also.
Angles vertically are always congruent. Accordingly, in this illustration, A, B, and C, D
Therefore, value of C = D (-3x)+ 58 = x – 2
By assembling,
(-3x )- x = (-2) - 58
By doing more math, 4x = 60 (-4x = - 60)
4 x = 60/4 x = 15 when both sides are divided.
So, ∠D = (x - 2) and

[tex]335.67-(72.04)[/tex]Since the money coming into his account and his balance have different symbols, we will add the two values and get the result.
[tex]=263.63[/tex] dollars.A set of data is represented in the stem plot below.
Part A: Find the mean of the data. Show each step of work. Round answer to the nearest whole number. (2 points)
Part B: Find the median of the data. Show each step of work. (2 point)
Part C: Find the mode of the data. Show each step of work. (2 point)
Part D: Compare your values for mean, median, and mode from parts A, B, and C. Explain which value would best represent the data, and why? (4 points)
A. Mean = 71
B. Median = 75
C. Mode = 0
D. Mean is used to represent data, because mean measures central tendency.
What is mean , median and mode?From the given stem we have to write a data set ,
Data set = 35, 42, 43, 51, 55, 57, 62, 66, 68, 69, 74, 75, 76, 77, 78, 79 , 82, 84, 86, 88, 93, 94, 101
Mean = average
= sum of all numbers / total number of values .
= 1635 / 23
= 71.08 = 71
Median = middle term
Total there are 23 terms so middle term is the 12th term .
So median = 75
Mode = Most repeated term or term that has high frequency.
Here no terms are repeating so mode = 0
By comparing mean , median and mode ,
Mean is used to represent data .Because, the mean is the most commonly used measure of central tendency because it averages all of the values in the data set.

Solve the following a)give the solution in calculator ready form (the exact value of x) and b)approximate the solution to the nearest hundredth.8. 3^2x - 12 * 3^x -28 =0
Given the following exponential equation:
[tex]3^{2x}^{}-12\cdot3^x-28=0[/tex]Note: the given equation is a quadratic equation
Let u = 3ˣ
So, the equation will be:
[tex]\begin{gathered} u^2-12u-28=0 \\ \text{factor}\rightarrow(u-14)(u+2)=0 \\ u-14=0\rightarrow u=14 \\ u+2=0\rightarrow u=-2 \end{gathered}[/tex]so,
[tex]\begin{gathered} 3^x=14 \\ or,3^x=-2 \end{gathered}[/tex]The negative result will be rejected because the range of the exponential function is greater than zero
So, the exact value of x will be as follows:
[tex]x=\frac{\log 14}{\log 3}[/tex]The approximate solution using the calculator will be:
x = 2.40
1/2Hd=d^2 solve for b
The solution of the equation for b is b= 2d²/H
What is subject of formula?This involves taking a variable in an equation to stand alone
Note that this variable is different from the initial isolated variable
How to determine the equation for b?The equation is given as
1/2Hb = d²
Divide both sides of the equation by H
So, we have the following equation
1/2Hb/H = d²/H
Multiply both sides of the equation by 2
So, we have the following equation
2 * 1/2Hb/H = d²/H * 2
Evaluate the quotients and the products
b= 2d²/H
The above computation implies that:
We changed the subject of the formula in the equation 1/2Hb = d² from d² to b
This implies that solving for b is a concept of subject of formula
Hence, the solution is b= 2d²/H
