This portion of the graph is completely flat, and has a slope of 0. The slope is the rate of change. Any horizontal line has a slope of 0 (we can use the slope formula to prove this). The term 'constant" means "it does not change".
In contrast, sections A, B, and D are all increasing sections because they go uphill as we move from left to right. The slopes of each line segment are positive.

The mean of a set of 10 numbers is 22. Four of these
numbers (8, 12, 21, and 23) are removed from the set.
What is the mean of the six remaining numbers?
A. 19
B. 21
C. 26
D. 28
==========================================================
Explanation:
The mean of all ten numbers is 22.
This tells us the sum of those ten numbers is 10*22 = 220
Recall that
mean = (sum of items)/(number of items)
We take this process in reverse to find the sum.
In other words:
sum = (mean)*(number of items)
--------------
Now remove the elements {8,12,21,23} to get a new sum of:
220-8-12-21-23 = 156
Divide that smaller sum over 6 since removing 4 elements leaves us with 10-4 = 6 left over.
new mean = (new smaller sum)/(number of items)
new mean = (156)/(6)
new mean = 26
Which rational expression is undefined when a=1
Answer:
[tex]\frac{10a + 6}{-a^2 + 1}[/tex] is undefined at a = 1
Step-by-step explanation:
Required
Which is undefined at a = 1
An expression is undefined when its denonimator equals 0.
So, we have to test the denominator of each.
(A): 7a + 7
This gives:
[tex]= 7(1) + 7[/tex]
[tex]= 7 + 7[/tex]
[tex]= 14[/tex]
(B): 5a - 10
This gives:
[tex]= 5(1) - 10[/tex]
[tex]= 5- 10[/tex]
[tex]= -5[/tex]
(C) -a² + 1
This gives
[tex]-(1^2) + 1[/tex]
[tex]= -1 + 1[/tex]
[tex]=0[/tex]
(D) 3a²
This gives:
[tex]= 3(1)^2[/tex]
[tex]= 3 * 1[/tex]
[tex]= 3[/tex]
Notice that only (C) equals 0.
Hence:
[tex]\frac{10a + 6}{-a^2 + 1}[/tex] is undefined at a = 1

The simplified trigonometric expression is given as follows:
[tex]-sin{\theta}\tan{\theta}(1 - \csc{\theta})[/tex]
How to simplify the given trigonometric expression?The expression is given by:
[tex]\frac{\cos{\theta}}{1 + \csc{\theta}} \times \frac{1 - \csc{\theta}}{1 - \csc{\theta}}[/tex]
Applying the subtraction of perfect squares at the denominator, we have that the expression is given by:
[tex]\frac{\cos{\theta}(1 - \csc{\theta})}{1 - \csc^2{\theta}}[/tex]
Applying an identity, we have that:
[tex]1 - \csc^2{\theta} = -\cot^2{\theta}[/tex]
Hence the expression is:
[tex]-\frac{\cos{\theta}(1 - \csc{\theta})}{\cot^2{\theta}}[/tex]
cot = cos/sin, hence:
[tex]-\frac{sin^2{\theta}(1 - \csc{\theta})}{\cos{\theta}}[/tex]
tan = sin/cos, hence the simplified expression is:
[tex]-sin{\theta}\tan{\theta}(1 - \csc{\theta})[/tex]

The amount of the profit will be $50,738.
What is a profit?A monetary profit, particularly the distinction between the amount gained and the actual cost of purchasing, running, or creating anything.
The profit is given as,
Profit = Selling price - Cost price
The Wind Up Corp computed their monthly expense equation is given below.
E = 3.2q + 56,000
Its products will be sold to retailers at a wholesale price of $9 each. If 18,403 units are sold. Then the expense will be
E = 3.2 x 18403 + 56000
E = $114,889
Then the selling price will be
S = 9 x 18403
S = 165,627

Trapezoid RSTV with vertices R(-1,1), S(4, 1), T(4, -1), and V(-1, -3) and is reflected across y = -3
The vertices of the image are R'(x, y) = (- 1, - 7), S'(x, y) = (4, - 7), T'(x, y) = (4, - 5) and V'(x, y) = (- 1, - 3).
What are the coordinates of the vertices of the image by using a reflection formula?
In this question we know the locations of the four vertices of the trapezoid RSTV and we need to determine the coordinates of its image by using a reflection formula about an axis parallel to the y-axis, whose formula is described below:
P'(x, y) = P(x, y) - 2 · [P(x, y) - (p, k)]
Where:
p - x-Coordinate of the original point.k - y-Coordinate of the reflection axis.P(x, y) - Original pointP'(x, y) - Resulting pointNow we proceed to find the coordinates of the images:
R'(x, y) = (- 1, 1) - 2 · [(- 1, 1) - (- 1, - 3)]
R'(x, y) = (- 1, 1) - 2 · (0, 4)
R'(x, y) = (- 1, 1) + (0, - 8)
R'(x, y) = (- 1, - 7)
S'(x, y) = (4, 1) - 2 · [(4, 1) - (4, - 3)]
S'(x, y) = (4, 1) - 2 · (0, 4)
S'(x, y) = (4, 1) + (0, - 8)
S'(x, y) = (4, - 7)
T'(x, y) = (4, - 1) - 2 · [(4, - 1) - (4, - 3)]
T'(x, y) = (4, - 1) - 2 · (0, 2)
T'(x, y) = (4, - 1) + (0, - 4)
T'(x, y) = (4, - 5)
V'(x, y) = (- 1, - 3) - 2 · [(- 1, - 3) - (- 1, - 3)]
V'(x, y) = (- 1, - 3) - 2 · (0, 0)
V'(x, y) = (- 1, - 3)
The vertices of the image are R'(x, y) = (- 1, - 7), S'(x, y) = (4, - 7), T'(x, y) = (4, - 5) and V'(x, y) = (- 1, - 3).

Given: AOB is a right angle
Prove: mBOC = 90°
O
B
Since
AOB is a right angle, it is 90°. AOB is supplementary to BOC,
so m AOB + m BOC = 180°. By the substitution property of equality,
90 + m BOC = 180°. Applying the subtraction property of equality,
m BOC = 90%.
What statement is missing from the proof?
The missing piece of information in the proof is that m∠DOA and m∠BOC are vertical opposite angles.
How to find vertically opposite angles?We want to prove that m∠BOC = 90°.
We are given that m∠AOB is a right angle triangle. Thus;
m∠BOC must also be equal to 90°
Now, since m∠BOC and m∠AOB are right angles, then it means that we must equally say that m∠DOA and m∠BOC are vertical opposite angles and they are as such equal.
Thus, the missing piece of information in the proof is that m∠DOA and m∠BOC are vertical opposite angles.

Find an equation of the line that passes through ( -3,-10) and (7,-8). You do not need to simplify
The equation of line that passes through the given points is x-5y=47.
Given that the line that passes through ( -3,-10) and (7,-8).
The standard form of the line equation is ax+by+c = 0. Here a, b are the coefficients, x, y are the variables and c are the constant terms. It is a quadratic equation, of the variables x and y. The values of x and y represent the coordinates of the point on the line in the coordinate plane.
Firstly, we will find the slope of equation of line by using the given points.
(x₁,y₁)=(-3,-10) and (x₂,y₂)=(7,-8).
m=(y₂-y₁)/(x₂-x₁)
Now, we substitute the values, we get
m=(-8-(-10))/(7-(-3))
m=(-8+10)/(7+3)
m=2/10
m=1/5
Further, we will find the equation of line using the formula y-y₁=m(x-x₁).
Now, we will substitute the values , we get
y-(-10)=(1/5)(x-(-3))
y+10=(1/5)(x+3)
Further, we will multiply both sides by 5, we get
5(y+10)=x+3
5y+50=x+3
5y+50-50=x+3-50
5y=x-47
x-5y=47
Hence, the equation of line that passes through ( -3,-10) and (7,-8) is x-5y=47.

A hotel rents 240 240 rooms at a rate of $ 40 $40 per day. For each $ 2 $2 increase in the rate, four fewer rooms are rented. Find the room rate that maximizes daily revenue. The rate that maximizes revenue is $
Answer:
The daily rate that maximizes the revenue is $40 and the maximum revenue is $9600
Step-by-step explanation:
Given
[tex]Rooms = 240[/tex]
[tex]Price= \$40[/tex]
[tex]Increment = \$2[/tex]
First, we calculate the revenue.
[tex]Revenue (r) = Price (p) * Number\ of\ Rooms(n)[/tex]
[tex]r = p*n[/tex]
Let x be the change in rate.
i.e.
For every 2x increment in price (p) i.e. p + 2x
There will be 4 fewer rooms (n) i.e. n - 4x
So, the revenue is updated as:
[tex]r = (p + 2x) * (n - 4x)[/tex]
[tex]Price = 40[/tex]
So:
[tex]r = (40 + 2x) * (n - 4x)[/tex]
[tex]Rooms = 240[/tex]
So:
[tex]r = (40 + 2x) * (240 - 4x)[/tex]
Expand
[tex]r = 40 * 240 - 40 * 4x + 2x * 240 - 2x*4x[/tex]
[tex]r = 9600 - 160x + 480x - 8x^2[/tex]
Reorder
[tex]r = -8x^2 - 160x + 480x + 9600[/tex]
[tex]r = -8x^2 +320x + 9600[/tex]
The maximum of a function is calculated as:
[tex]Max = -\frac{b}{2a}[/tex]
In: [tex]r = -8x^2 +320x + 9600[/tex]
[tex]a = -8[/tex] [tex]b = 320[/tex] [tex]c = 9600[/tex]
So:
[tex]Max = -\frac{b}{2a}[/tex]
[tex]Max = -\frac{320}{-8}[/tex]
[tex]Max = \frac{320}{8}[/tex]
[tex]Max = 40[/tex]
To get the maximum revenue;
Substitute 40 for x in [tex]r = -8x^2 +320x + 9600[/tex]
[tex]r = -8(40)^2 + 320 * 40 + 9600[/tex]
[tex]r = 9600[/tex]
The daily rate that maximizes the revenue is $40 and the maximum revenue is $9600

5¹²/₁₅ can be broken down into 5⁴/₅
For the second mixed fraction which is 5²⁸/₄₀;
5²⁸/₄₀ can be broken down into 5⁷/₁₀
Now, 7/10 is lesser than 4/5 and so 5⁴/₅ is greater than 5²⁸/₄₀. Thus, ranking of all numbers from least to greatest is; 5, 5²⁸/₄₀, 5⁴/₅
