Which transformation is this an example of?
A. reflection
B. rotation
C. translation
D. None of these
Answers
Answer:
B. rotation
Step-by-step explanation:
A reflection would mean that the shape would be mirrored across the y-axis or the x-axis. A translation means that nothing about the shape changes except for the location. A dilation (not an answer option but still helpful to know) is the change in size of the shape. And finally, the correct answer for this problem, a rotation means that the shape is rotated at a specific point.
I included a picture that uses a shape to help explain this idea. I hope this helps! Have a lovely day!! :)
explanation: reflection is a mirrored version of it.
translation is where it doesn’t change at all except for where it is.
rotation is where it flips horizontal to vertical over and over.
find the inverse of the function
Answers
as you already know, to get the inverse of any expression we start off by doing a quick switcheroo on the variables and then solving for "y", let's do so.
[tex]\stackrel{h(x)}{y}~~ = ~~6\sqrt[3]{2x+5}-1\implies \stackrel{\textit{quick switcheroo}}{x~~ = ~~6\sqrt[3]{2y+5}-1} \\\\\\ x+1=6\sqrt[3]{2y+5}\implies \cfrac{x+1}{6}=\sqrt[3]{2y+5}\implies \left( \cfrac{x+1}{6} \right)^3=\left( \sqrt[3]{2y+5} \right)^3[/tex]
[tex]\left( \cfrac{x+1}{6} \right)^3=2y+5\implies \left( \cfrac{x+1}{6} \right)^3-5=2y\implies \cfrac{\left( \frac{x+1}{6} \right)^3-5}{2}=y \\\\\\ \cfrac{\left( \frac{x+1}{6} \right)^3}{2}-\cfrac{5}{2}=y\implies \cfrac{~~ \frac{(x+1)^3}{6^3}~~}{2}-\cfrac{5}{2}=y\implies \cfrac{(x+1)^3}{432}-\cfrac{5}{2}=\stackrel{y}{h^{-1}(x)}[/tex]
two gymnasts are running toward each other in a floor routine, and they plan to precisely time a flip to stay synchronized for the audience. The path of the gymnasts is parabolic and modeled by the following equations, where y is the height of the flip and x is the time in seconds:
y = – (x – 5)2 + 3
y = –3(x –3)2 + x + 1
30 POINTS !! To make sure the flip is in unison, after how many seconds should the flip occur?
2 seconds
3 seconds
4 seconds
5 seconds
Answers
To make sure the flip is in unison, after 4 seconds should the flip occur, as given by the option C: 4 seconds.
What does synchronized motion mean?Synchronized motion is a motion of two or more system which goes in syncronization with each other.
For this case, the flip will occur such that both gymnasts are synchronized and flip is unison (simultaneous).
For that, we need the time(x) and the height (y) same.
Since the motion paths are:
[tex]y= -(x-5)^2 + 3\\\\y = -3(x-3)^2 + x + 1[/tex]
Therefore, we need to find the values of x for which same y comes as output.
Let x = t be the time for which the height y is same, then:
[tex]-(t-5)^2 + 3 = -3(t-3)^2 + t + 1[/tex] = height achieved by both gymnasts.
Solving it further:
[tex]-(t-5)^2 + 3 = -3(t-3)^2 + t + 1\\3(t^2 + 9 -6t) -(t^2 + 25 -10t) -t + 2 = 0\\\\2t^2 -9t + 4 = 0\\2t^2 -8t - t + 4 = 0\\2t(t-4) -1(t-4) = 0\\(2t -1)(t-4) = 0\\\\t = 4, t = 1/2[/tex]
Assuming they planned to do flip after integral number of time in seconds, the correct option is t = 4 seconds.
Thus, to make sure the flip is in unison, after 4 seconds should the flip occur, as given by the option C: 4 seconds.

What is the circumference of a circle with a diameter of 8 inches?
a 12.56
b 25.12
c 50.24
d 200.96
Answers
A Circle is a closed plane geometric shape figure. The diameter of a circle is the longest chord of a circle. The radius drawn perpendicular to the chord bisects the chord. A Circle is always lie at an equal distance from a center point. Circles having different radius are similar.
Circumference of Circle:The circumference of a circle is the product of pi and length of the diameter of a circle. Mathematically;
[tex]\longrightarrow \tt{Circumference_{(circle)} = \pi{D}}[/tex]
Here, D is the diameter of the circle or distance between the circle.
Elucidation:We are asked to find the circumference of the circle if the diameter is 8 inches.
We know that, The circumference of a circle is the product of pi and length of the diameter of a circle. Therefore;
[tex]\implies \tt{Circumference_{(circle)} = \pi{D}}[/tex]
[tex]\implies \tt{Circumference_{(circle)} = 3.14 \times 8}[/tex]
[tex]\implies \boxed{\pmb{\tt{Circumference_{(circle)} = 25.12}}}[/tex]
Hence, the circumference of the circle is 25.12 inches. So option (B) is correct.
Answer:
Circumference of circle = 25.12 inchesThus Option B is correct .Step-by-step explanation:
In the question we are given that diameter of circle is of 8 inches . And we have asked to find the circumference of the circle .
For finding circumference of circle we must have to know that what is the formula for finding circumference of circle. So :
[tex] \quad \quad \: \red{\underline{\pink{ \boxed{ \frak{Circumference \: of \: Circle =2 \pi r }}}}}[/tex]
Where ,
π refers to 3.14 r refers to radius of circleSolution : -
As in the question we are given length of diameter . So for finding circumference we need to find the radius of circle .
We know that diameter of circle is two times its radius ,
[tex] \qquad \: \rm {Diameter = 2 × Radius }[/tex]
So for radius we are dividing both side with 2 :
[tex]\qquad \: \rm { \dfrac{Diameter}{2} = \dfrac{ \cancel{2} × Radius}{ \cancel{2}} }[/tex]
We get that ,
[tex] \qquad \: \rm {Radius = \dfrac{Diameter}{2} }[/tex]
Therefore , we can say that radius of circle is half of its diameter .
Now using this , firstly we are finding radius of circle . So :
[tex] \longmapsto \quad \: \boxed{\rm{ Radius = \frac{8}{2} \: \: inches}}[/tex]
Therefore , radius of circle is 4 inches .Now , we are moving towards our final solution .
So ,
[tex] \longmapsto \quad Circumference_ { (Circle)} =2 \times 3.14 \times 4 [/tex]
Multiplying 2 with 3.14 :
[tex]\longrightarrow \quad Circumference_ { (Circle)} = 6.28 \times 4 [/tex]
Multiplying 4 and 6.28 :
[tex]\longrightarrow \quad \purple{{\boxed{\frak{Circumference_ { (Circle)} = 25.12\: inches }}}}[/tex]
Therefore , circumference of circle having diameter 8 inches is 25.12 inches and hence option b is correct .#Keep LearningAt a local high school, enrollment in the drama club increases by 5% each year. what is the common ratio in this situation? 0.05 0.95 1.05 1.95

What is the percentage?A percentage is a minimum number or ratio that is measured by a fraction of 100.
At a local high school, enrollment in the drama club increases by 5%.
Let an initial number of students in high school be 'a'.
so next year increase in students will be = 5% of a

The expected number of vowels in 30 spins is:
Expected = Vowels/Sections * 30

There are 420 fans at a high school basketball game. The ratio of students to parents is 5 to 2. Exactly how many more students are there than
parents at the game?
Answers
Answer:
180 more students than parents at the game
Step-by-step explanation:
There are 5 students for every 2 parents equalling 7 people in one set of students to parents ratio.
There are 420 fans at the game. Divide the 420 by the 7 people per set.
420 / 7 = 60 (There are 60 sets of 5 students to 2 parents ratio)
Multiply the 60 sets by 5 students and 2 parents, respectively:
60 x 5 = 300 students
60 x 2 = 120 parents
Subtract the number of parents from number of students:
300 students - 120 parents = 180 more students
