Describe the sequence of transformations that maps triangle XYZ onto triangle X”Y”Z”
Answer:
1. Translation 5 units to the left and 1 unit down
2. Reflection across the x-axis
Step-by-step explanation:
Triangle XYZ has its vertices at points X(-6,2), Y(-4,7) and Z(-2,2).
1. Translate triangle XYZ 5 units to the left and 1 unit down. This translation has the rule:
[tex](x,y)\rightarrow (x-5,y-1)[/tex]
Then
[tex]X(-6,2)\rightarrow X'(-11,1);[/tex]
[tex]Y(-4,7)\rightarrow Y'(-9,6);[/tex]
[tex]Z(-2,2)\rightarrow Z'(-7,1).[/tex]
2. Reflect triangle X'Y'Z' across the x-axis. This reflection has the rule:
[tex](x,y)\rightarrow (x,-y)[/tex]
Then
[tex]X'(-11,1)\rightarrow X''(-11,-1);[/tex]
[tex]Y'(-9,6)\rightarrow Y''(-9,-6);[/tex]
[tex]Z'(-7,1)\rightarrow Z''(-7,-1)[/tex]
These points are exactly the vertices of the triangle X''Y''Z''.
The sequence of transformations is translation, rotation, reflection, and dilation.
Explanation:The sequence of transformations that maps triangle XYZ onto triangle X"Y"Z" is:
Translation: Move the triangle in a linear direction without rotating it.
Rotation: Rotate the triangle about a fixed point or axis.
Reflection: Mirror the triangle across a line known as the axis of reflection.
Dilation: Increase or decrease the size of the triangle while preserving its shape.
By applying these transformations in the specified sequence, triangle XYZ can be mapped onto triangle X"Y"Z".
Can I get a check to see if these are right please?

Two sides of an acute triangle measure 5 inches and 8 inches. The length of the longest side is unknown.
What is the greatest possible whole-number length of the unknown side?
The greatest whole possible whole number length of the unknown side is 9 inches
Solution:
Two sides of an acute triangle measure 5 inches and 8 inches
The length of the longest side is unknown
We have to find the length of unknown side
The longest side of any triangle is a hypotenuse
For a acute triangle we know:
If c is the longest side of a acute triangle, a and b are other two sides of a acute triangle then the condition that relates these three sides are given as:
[tex]c^2<a^2+b^2[/tex]
Here in this sum,
a = 5 inches
b = 8 inches
c = ?
Substituting we get,
[tex]c^2< 5^2+8^2\\\\c^2 < 25 + 64\\\\c^2 < 89\\\\c < 9.4[/tex]
On rounding to nearest whole number,
c < 9
Hence, to the greatest whole possible whole number length of the unknown side is 9 inches
Answer:
The greatest whole possible whole number length of the unknown side is 9 inches
Step-by-step explanation:
A cone with a radius of 6 cm and a height of 8 cm has the same volume as a cylinder with a height of 6 cm. What is the radius
of the cylinder?
A)4 cm
B)4 cm
C)6 cm
D) 8 cm
Answer:
The radius of the cylinder is 4 cm.
Step-by-step explanation:
Given:
radius of cone = 6 cm
height of the cone = 8 cm
height of cylinder = 6 cm
We need to find the radius of cylinder.
Solution:
First we will find the volume of cone.
Volume of cone is one third time square of radius times height times π.
framing in equation form we get;
Volume of cone = [tex]\frac{1}{3}\pi r^2h = \frac{1}{3}\pi\times 6^2\times 8 \approx 301.44 \ cm^3[/tex]
Now Volume of cylinder is given by square of radius times height times π.
framing in equation form we get;
Volume of cylinder = [tex]\pi r^2h=18.84r^2[/tex]
Now it has been given that;
Volume of cone is equal to Volume of cylinder.
so we can say that
[tex]18.84r^2=301.44[/tex]
Dividing both side by 18.84 we get;
[tex]\frac{18.84r^2}{18.84}=\frac{301.84}{18.84}\\\\r^2\approx16[/tex]
Taking square root on both side we get;
[tex]\sqrt{r^2}=\sqrt{16} \\\\r=4\ cm[/tex]
Hence the radius of the cylinder is 4 cm.
Match each three-dimensional figure to its volume based on the given dimensions. (Assume T = 3.14.)
a right cylinder with radius 4 cm
and height 3 cm
314 cu cm
a cone with radius 5 cm and
height 12 cm
160 cu cm
a pyramid with base area
16 sq cm and height 30 cm
48 cu cm
a pyramid with a square base of
length 3 cm and height 16 cm
150.72 cu cm
A right circular cylinder with radius 4 cm and height 3 cm-150.72 cu cm
A cone with radius 5cm and height 12 cm-314 cu cm
A pyramid with base area 16 sq cm and height 30 cm-160 cu cm
A pyramid with a square base of length 3 cm and height 16 cm-48 cu cm
Explanation
volume of cylinder=[tex]\pi r^2h[/tex][tex]3.14*4^2*3=150.72[/tex] cu cm
volume of cone=[tex]1/3 \pi r^2 h[/tex]=314 cu cm
volume of pyramid=[tex](base area*height)/3=(16*30)/3[/tex]=160 cu cm
volume of pyramid=
=[tex](base area*height)/3\\square base length=3 cm\\base area=a^2 =3^2 =9\\volume=(9*16)/3=48cm^3[/tex]
What is an equation that passes through the points (3,8) and (1,0)
Answer:
y=4x-4
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(0-8)/(1-3)
m=-8/-2
m=4
y-y1=m(x-x1)
y-8=4(x-3)
y=4x-12+8
y=4x-4
Answer:y - 4x + 4 = 0
Step-by-step explanation: Formula for equation of a line passing through two coordinates is
y - y₁ y₂ - y₁
______ = ______
x - x₁ x₂ - x₁
Therefore, y₂ -y₁
y - y₁ = ____ × ( x - x₁ )
x₂ - x₁
where x₁ =3, y₁ =8, x₂ = 1 and y₂ 0
Now substitute for the value
y - 8 = 0 - 8
______ x ( x - 3 )
1 - 3
Therefore y - 8 = -8/-2 × (x - 3 )
y - 8 = -8/-2 × (x - 3)
y -8 = 4 × (x - 3 )
y - 8 = 4( x - 3 )
y - 8 = 4x - 12, when the brackets are open,
So y = 4x - 12 + 8
y = 4x - 4
Therefore the equation of the line is
y - 4x + 4 = 0
The price of a movie ticket increased from $25 to $30 What does this mean about the new price?
Choose the correct answer below
O A. The new price is 80% of the old price because 25-30 s 8. or 80%
OB. The new price is 80% of the old price because the price decreases by 20%, which is subtracted from 100%
OC. The new price is 125% of the old price because the price increases by $5, which is multiplied by the original price 5x 25 = 125%
O D. The new price is 20% of the old price because the price increases by 55 and 55 is 20% of $25
OE. The new price is 120% of the old price because the price increases by 20%, which is added to 100%
O F. The new price is 750% of the old price because 25 x 30 = 750
The correct option will the new price is 120% of the old one because the price increases by 20%, which is added to 100%.
What is percent of change?Percent of change is determined by the difference between the two values divided by the orginal one, then multiplied by 100.
i.e. percent of change=(change in value/original value)*100
So according to the asked question,
old value of the shoes=$25
new value of the shoes=$30
change in value=30-25=$5
percent of change=((30-25)/25)*100=20%
hence price increases by 20%.
If the old price is 100 and price increases by 20% then new price will be 120.
So the new price is 120% of the old one.
in another way we can calculate that
old value*x%=new value
⇒old value*x/100=new value
⇒x=new value*100/old value=30*100/25=120%
Therefore the new price is 120% of the old one because the price increases by 20%, which is added to 100%.

Sum of first 1000 consecutive odd counting numbers
Answer:
100,000,000
Step-by-step explanation:
did some research to solve this one, i recommend looking more into to it to ensure that this is the correct answer ;)
The sum of the first 1000 consecutive odd counting numbers is 1,000,000.
To find the sum of the first 1000 consecutive odd counting numbers, we need to recognize a pattern and utilize a simple formula.
Step 1: Identify the Sequence of Odd Numbers
The first few odd counting numbers are:
1, 3, 5, 7, 9, 11, 13, ...
Step 2: Determine the Formula for the Sum
The sum of the first n odd counting numbers can be calculated using the formula:
Sum = n²
This means that the sum of the first n consecutive odd numbers is equal to the square of n.
Step 3: Apply the Formula to Our Problem
In this case, we want to find the sum of the first 1000 odd numbers. Therefore, we set n to 1000:
Sum = 1000²
Step 4: Calculate the Value
Now, we perform the calculation:
Sum = 1000 * 1000 = 1,000,000

Please help! An angle measuring 3.5 radians is equal to which of the angle measures given below? (Use 3.4 for pi). Check ALL that apply.
A) 630 degrees
B) 200.64 degrees
C) 200 degrees 38'24"
D) 210 degrees
The measure of the angle is;
200.64 degrees ⇒ B
200 degrees 38' 24" ⇒ C
Step-by-step explanation:
To convert the measure of an angle from degrees to radians or from radians to degrees use these rules
If the measure of the angle is x°, then multiply it by [tex]\frac{\pi }{180}[/tex] to find its measure in radiansIf the measure of the angle is x radians, then multiply it by [tex]\frac{180}{\pi }[/tex] to find its measure in degrees∵ The measure of an angle is 3.5 radians
- We need to change its measure to degree, use the 2nd rule
∵ π = 3.14
∴ Its measure in degree = [tex](3.5).(\frac{180}{3.14})[/tex]
∴ Its measure in degree = 200.64°
To find its measure in degree, minutes and seconds, multiply the number before decimal point by 60 to find the number of minutes
∵ 1° = 60'
∵ 0.64 × 60 = 38.4
- That means the number of minutes is 38
∵ 1' = 60"
∵ 0.4 × 60 = 24
- That means the number of seconds is 24
∴ The measure of the angle is 200° 38' 24"
The measure of the angle is;
200.64 degrees
200 degrees 38' 24"

Consider the following piece-wise function. Which of the below correctly describes the graph shown?
Answer:
C
Step-by-step explanation:
The function is formed of 2 straight lines
The equation of a straight line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate the slope using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (- 4, - 5) and (x₂, y₂ ) = (2, - 2) ← endpoints of left line
m = [tex]\frac{-2+5}{2+4}[/tex] = [tex]\frac{3}{6}[/tex] = [tex]\frac{1}{2}[/tex]
Note the line crosses the y- axis at (0, - 3) ⇒ c = - 3
y = [tex]\frac{1}{2}[/tex] x - 3 for x < 2 ( arrow on line points left )
Repeat
with (x₁, y₁ ) = (2, - 2) and (x₂, y₂ ) = (3, 1) ← 2 points on right line
m = [tex]\frac{1+2}{3-2}[/tex] = [tex]\frac{3}{1}[/tex] = 3, thus
y = 3x + c ← is the partial equation
To find c substitute either of the 2 points into the partial equation
Using (3, 1), then
1 = 9 + c ⇒ c = 1 - 9 = - 8
y = 3x - 8 for x ≥ 2 ( arrow on line points right )
