Triangle NGM is reflected across the x-axis, and is dilated by a factor of
\(2 \frac{1}{2} \)
what are the coordinates of vertices N'G'M'
The coordinates of vertices N'G'M' are N'(-10, -15), M'(-15, -5) and G'(-5, -10).
From the given graph, N(-4, 6), M(-6, 2) and G(-2, 4).
Scale factor = \(2\frac{1}{2}\)
= 2.5
The reflection of point (x, y) across the x-axis is (x, -y).
Here, N(-4, 6)→(-4, -6)
M(-6, 2)→(-6, -2)
G(-2, 4)→(-2, -4)
Now, with scale factor 2.5, we get
(-4, -6)→2.5(-4, -6)→N'(-10, -15)
(-6, -2)→2.5(-6, -2)→M'(-15, -5)
(-2, -4)→2.5(-2, -4)→G'(-5, -10)
Therefore, the coordinates of vertices N'G'M' are N'(-10, -15), M'(-15, -5) and G'(-5, -10).

Step-by-step explanation:
A regular polygon is shown with one of its angle measures labeled a.
If m∠a = (2z + 54)°, find the value of z.
z = 63
z = 9
z = 18
z = 27
Answer:
(d) z = 27
Step-by-step explanation:
You want the value of z where one interior angle of a regular pentagon has the measure (2z +54)°.
Interior anglesThe measure of an interior angle of a regular n-gon is ...
a = 180° -360°/n
For n=5, this is ...
a = 180° -360°/5 = 180° -72° = 108°
The problem statement tells us this is equal to the given angle expression:
108° = (2z +54)°
54 = z +27 . . . . . . . . divide by 2°
27 = z . . . . . . . . . . . subtract 27
The value of z is 27.

Additional comment
We used the fact that exterior angles of a convex polygon total 360°, and the adjacent interior angle is the supplement of that. The angle expression is often expressed as the total of interior angles being ...
180°(n -2) . . . sum of interior angles of n-gon
The angles of a regular polygon are congruent. Since we want one of those angles, we can divide by n. When we do that, we get the expression above.
The equation for the angle value is a "2-step" equation. The usual procedure for solving it is to subtract the unwanted constant (54), then divide by the coefficient of the variable. Here, we observed that all of the numbers had that coefficient (2) as a factor, so we chose to do the division first. This makes the numbers smaller and perhaps easier to work with mentally.

Answer:
The first option, V ≈ 1607.7 in²
Step-by-step explanation:
Find the volume of the given cylinder.
\(\begin{center}\framebox{\parbox{4cm}{\textbf{Volume of a Cylinder:}\\[2ex]The volume of a cylinder with radius $r$ and height $h$ is given by the formula:\\[2ex]\center{$V = \pi r^2 h$} \\ \\}}\end{center}\)
Given:
r = 8 in
h = 8 in
π = 3.14
Find:
V = ?? in³
\(\hrulefill\)
Now solving,
Substitute the given values into the formula:
=> V = (3.14)(8)²(8)
Using a calculator to simplify:
=> V = 1607.68 in²
Rounded to the nearest tenth:
∴ V ≈ 1607.7 in²
Thus, the first option is correct.
Rewrite x/-4 ≥ -1 so the negative sign in the fraction is with x
Answer: 4 over 1
Step-by-step explanation:
Directions: Follow the instructions for the following inequalities.
1. 4 < 7 Multiply both sides by 3, then by 2, then by 4, then by 9
2. 11 > -2 Add 3 to both sides, then add 3, then add (-4)
3. -2 less than or equal to -2 Subtract 6 from both sides, then 8, and then 2
4. -4 < 8 Divide both sides by -4, then by -2
5. Write a short explanation of the effects of the above operations. Did this affect the inequality sign? Was it still true? Why or why not?
Answer:
1. 504 < 1512
2. 12 > 0
3. -2 = -2
4. -1 < 2
Step-by-step explanation:
Given that both sides are being changed by the same amount and sign, the sign never changes. They always have the same value.

Answer:
vertex (-4,-1)
2nd point ( 0,31)
Step-by-step explanation:
f(x) = 2x^2 + 16x + 31
First find the vertex
The x coordinate of the vertex is -b/2a where ax^2 +bx +c
-16/ 2(2) = -16/4 = -4
Substitute into the function
f(-4) = 2 ( -4)^2 +16(-4) +31
= 2 *16-64 + 31
= 31 -64 +31
= -1
The vertex is at ( -4,-1)
Another point can be x=0
f(0) = 0+16(0)+31
= 31
( 0,31)

A comet travelling through space at a rate of 75 miles per hour has just flown into a huge amount of space dust. This dust decreases the speed of the comet by 15 miles every hour, until it completely stops moving. Which are the domain and range of the linear function that represents this relationship?
Answer:
Linear function: y = -15x + 75
Domain: x ≤ 5
Range: y ≥ 0
Please tell me if there are any mistakes in my answer and I will correct them.
Step-by-step explanation:
The linear function is y = -15x + 75, written in y=mx+b form. X is the amount of hours. Since the speed is decreasing, we will use -15. Since we started at 75 miles per hour, our b value will be 75.
DomainThe domain is all the possible values for x.
Since the comet slows down by 15 miles every hour until it stops moving, we can solve for x by putting in 0 for y.
0 = -15x + 75
15x = 75
x = 5
Therefore, the domain is x ≤ 5.
RangeThe range is the set of all possible values of y. In this case, the range can be anything but 0 in order for the equation to make sense.
So, the range is y ≥ 0.
Answer:
domain is 0,5

A histogram shows the number of magazines read last month by the students in a class. What percent of the students read less than six magazines?
can you find the mean and median of the data? Explain.
74% percent of the students read less than six magazines
What is Percentage?percentage, a relative value indicating hundredth parts of any quantity.
A histogram shows the number of magazines read last month by the students in a class
The total number of students are 2+15+3
Number of students=23
Number of students read less than six magazines is 17
Now let us find 17 is what percent of 23
x/100×23=17
23x=1700
Divide both sides by 23
x=1700/23
x=73.9
x=74%
Hence, 74% percent of the students read less than six magazines
