The rule of reflection for the triangle is Ry ( x , y ) → ( -x , y )
What is Reflection?Reflection is a type of transformation that flips a shape along a line of reflection, also known as a mirror line, such that each point is at the same distance from the mirror line as its mirrored point. The line of reflection is the line that a figure is reflected over. If a point is on the line of reflection then the image is the same as the pre-image. Images are always congruent to pre-images.
The reflection of point (x, y) across the x-axis is (x, -y). When you reflect a point across the y-axis, the y-coordinate remains the same, but the x-coordinate is taken to be the additive inverse. The reflection of point (x, y) across the y-axis is (-x, y).
Given data ,
Let the triangle be represented as ΔMLN
Now , the coordinates of the triangle are
The coordinate of M = M ( -5 , 4 )
The coordinate of L = L ( -6 , 2 )
The coordinate of N = N ( -3 , 2 )
when the triangle is reflected across the y-axis, the y-coordinate remains the same, but the x-coordinate is taken to be the additive inverse.
The reflection of point (x, y) across the y-axis is (-x, y).
So , the coordinate of M' = M' ( 5 , 4 )
The coordinate of L' = L' ( 6 , 2 )
The coordinate of N' = N' ( 3 , 2 )
Hence , the rule of reflection is Ry ( x , y ) → ( -x , y )

The exact value of sin(π/12) is ±√(2 - √3)/2 by using half-angle formula
To find the exact value of sin(π/12), we can use the half-angle formula for sine:
sin(x/2) = ±√[(1 - cos(x))/2]
In this case, x = π/6.
Therefore, we can use the half-angle formula with x = pi/6 to find the exact value of sin(π/12).
sin(pi/12) = ±√[(1 - cos(π/6))/2]
Let's calculate the value step by step:
cos(π/6) = √3/2
sin(π/12) = ±√[(1 - √3/2)/2]
To simplify further, let's rationalize the denominator:
sin(π/12) = ±√[(2 - √3)/4]
sin(π/12) = ±√(2 - √3)/2
Therefore, the exact value of sin(π/12) is ±√(2 - √3)/2.

Find the vertical, horizontal, and slant asymptotes, if any, for f(x)=5x^3-51x^2+77x+100/x^2-11x+24
Answers
Answer:
Step-by-step explanation:
Given: f(x)=5x^3-51x^2+77x+100/x^2-11x+24
Please use parentheses to eliminate any ambiguity:
f(x) = (5x^3-51x^2+77x+100) / (x^2 - 11x + 24)
or (better yet):
5x^3-51x^2+77x+100
f(x) = ---------------------------------
x^2 - 11x + 24
The vertical asymptotes here are at the zeros of the denominator:
x^2 - 11x + 24 = 0, This quadratic equation has coefficients a = 1, b = -11 and c = 24. Thus, its roots (zeros) are:
-(-11) ± √( 121 - 4(1)(24) )
x = -------------------------------------
2(1)
or:
11 ± √( 25 )
x = --------------------
2
or: x = 8 and x = 3
The vertical asymptotes are x = 8 and x = 3.
If we attempt to divide x^2 - 11x + 24 into 5x^3 - 51x^2 + 77x + 100, we see that the first term of the quotient is 5x. As x increases or decreases without bound, 5x goes to either ∞ or -∞, so we conclude that there is no horiz. asymptote. Continuing this division results in:
5x + 4 + a fraction
This represents the slant asymptote, y = 5x + 4

Suppose that you ask three friends to go to the mall. Each one has a 0.70 chance of saying yes. What is the probability that all three friends will say they can go to the mall with you? a. 0.027 c. 0.343 b. 0.21 d. 0.657
Answers
____________________________________________________
Answer:
Your answer would be 0.343.
____________________________________________________
Step-by-step explanation:
In the probability questions like this one, in order to get the answer,we would use the multiplication rule.
In your questions, we are trying to find the probability of ALL of your friends going to the mall with you.
Lets make it easier for you.
Whenever in probability you can say and, you multiply.
This means that you would try to find if friend 1 and friend 2 and friend 3 will say yes.
That's the same as saying friend 1's probability × friend 2's probability × friend 3's probability
We know that each friend has a 0.70 chance of saying yes.
Using the multiplication rule, we would just multiply 0.7 three times.
[tex]0.7 *0.7*0.7=0.343[/tex]
When you multiply, you should get 0.343.
There is a 0.343 chance of ALL your friends saying yes to go to the mall with you.
0.343 would be your FINAL answer.
____________________________________________________
To solve this problem, you need to consider the probability of each friend agreeing to go to the mall individually, then multiply these probabilities together to find the probability that all three will say yes.
Since each friend has a 0.70 chance of saying yes, we can calculate the combined probability as follows:
For the first friend, the probability is 0.70.
For the second friend, the probability is also 0.70.
For the third friend, the probability remains 0.70.
To find the combined probability that all three friends will say yes, we multiply the individual probabilities together:
\( Probability (All Say Yes) = Probability (Friend1 says Yes) \times Probability (Friend2 says Yes) \times Probability (Friend3 says Yes) \)
\( Probability (All Say Yes) = 0.70 \times 0.70 \times 0.70 \)
When you calculate this, you get:
\( Probability (All Say Yes) = 0.343 \)
So the answer is c. 0.343.

What is the slope of the function?
-10, -5, 5, 10
Answers
It is -10
Because when you take two points from the table and put it into the equation y=my+b...
So for example, take (-4,-16) from the table and substitute into x and y...
-16=m(-4) + b
And then substitute all the options given in the question, so I tried -10 first and put it in the place of m( in the equation) because m is the slope.
Then the equation would look like this:
-16= -10(-4) +b
Now solve for b
B= 24
And then check your answer by the RHS and LHS Method..
-16=-40 +24
Which is equal to:
-16=-16
There fore the the slope of this equation is 10
Answer: 5
Step-by-step explanation:
The formula to find slope is given by :-
[tex]\text{Slope}=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
From the given table in picture,
Take [tex]x_1=0\ ;\ y_1=4\\\\x_2=2\ ;\ y_2=14[/tex]
Then, slope of the given function will be given by :-
[tex]\text{Slope}=\dfrac{14-4}{2-0}\\\\\Rightarrow\text{Slope}=\dfrac{10}{2}=5[/tex]
Hence, the slope of the given function = 5
