Quadrilateral QRST is shown. Two students each perform a different reflection on
the original figure.
Use the drop-down menus to give the coordinates of point T' after each reflection
Answers
When Ramona reflect the original figure over the x-axis, the coordinate of point T' will be (-2, -4). When Elias reflect the original figure over the y-axis, the coordinate of point T' will be (2, 4).
What is a reflection?A reflection can be defined as a type of transformation which moves every point of the object by producing a flipped but mirror image of the geometric figure.
In Mathematics, a reflection over the x-axis is given by this transformation rule:
(x, y) → (x, -y)
Point T = (-2, 4) → Point T' = (-2, -4)
In Geometry, a reflection over the y-axis of a graph is given by this transformation rule (x, y) → (-x, y). This ultimately implies that, the coordinates of point T' after a reflection over the y-axis is as follows:
Point T = (-2, 4) → Point T' = (-(-2), 4) = (2, 4)

The ascending order of the given numbers is 2×[tex]10^{-4}[/tex] <0.004< 4×[tex]10^{-2}[/tex] < 0.042 < 0.24
The first number = 0.24
The second number = 4×[tex]10^{-2}[/tex]
The second number is the form of scientific notation. To compare the numbers, all the numbers should be in same form. So we have to convert the scientific notation to the decimal form
4×[tex]10^{-2}[/tex] = 0.04
The third number = 0.042
Third number is decimal form
The fourth number = 2×[tex]10^{-4}[/tex]
Convert the scientific notation to the decimal form
2×[tex]10^{-4}[/tex] = 0.0002
The fifth number = 0.004
The order of the numbers from least to greatest
= 2×[tex]10^{-4}[/tex] <0.004< 4×[tex]10^{-2}[/tex] < 0.042 < 0.24
Hence, the order of the given numbers from least to greatest is 2×[tex]10^{-4}[/tex] <0.004< 4×[tex]10^{-2}[/tex] < 0.042 < 0.24

What is the equation of the line that passes through the points (-3 , 9) and (9 , -1)? Write in your answer in slope - intercept form.
Please help
(College Algebra)
Answers
The equation of the line that passes through the points (-3,9) and (9,-1) is y= -5x/6 + 39/6 .
The equation of line passing through two points (a,b) and (c,d) is given by the equation
(y-b)=m(x-a) ,
where m is the slope of the line ..
the slope m is (d-b)/(c-a)
In the question ,
it is given that
the required line passes through the points (-3,9) and (9,-1)
by formula m= (-1-9)/9-(-3)
= -10/12
So substituting the values in the formula the equation of the line becomes
y-9 = -10/12*(x-(-3))
12*(y-9) = -10*(x+3)
12y - 12*9 = -10x-30
12y-108= -10x -30
12y = -10x-30+108
12y = -10x + 78
On Dividing both sides by 12 , we get
y= -10x/12 + 78/12
y= -5x/6 + 39/6
Therefore , the equation of the line in slope intercept form that passes through the points (-3,9) and (9,-1) is y= -5x/6 + 39/6 .

The value of arithmetic progression of p = 0 and q = 10
What is arithmetic progression ?When there are identical differences between every two next words, the series is known as an arithmetic progression (AP). There is a chance to find a formula for the nth term of the AP using this kind of development. The series 2, 6, 10, 14, etc., for instance, is an example of an arithmetic progression (AP) because it follows a pattern in which each number is acquired by adding 4 to the preceding word.
Given that : -10,p,q,20 are in A.P
if this -10,p,q,20 are in A.P then it must follow
2b = a+ c
2p = -10 + q ... (i)
2q= p+20 ....(ii)
Solving both equation we get
Multiplying (1) with 2,
4p - 2q = -20
Now adding both the equations
4p - 2q + 2q - p = 0
3p = 0
p = 0
Then, q = 0 + 10 = 10

Answers
C. The image shows two right triangles with one pair of congruent leg and congruent hypotenuse. Therefore, the congruence is HL.
D. This shows two right triangles that share one side (a leg) and have the other leg also congruent to each other. Therefore, their congruence is LL and SAS (leg, right angle, leg).
E. This shows two triangles with a pair of congruent sides, a pair of congruent angles, and they have a common side, therefore congruent since they are the same.
So, their congruence is SAS.
F. This shows two right triangles sharing the same hypotenuse, and with a pair of congruent angles. Therefore, their congruence is HA.
G. This shows two right triangles with congruent hypotenuses, one congruent pair of legs, and two congruent pairs of angles (if we include the right angle).
So, their congruence is HA and HL.
H. The two triangles here have a right angle, a pair of congruent sides, and a pair of angles that are opposite by vertex, so they are also congruent angles.
Therefore, their congruence is ASA.

The mean and standard deviation for the number of correct answers for such students is; μ = 6.5 and σ = 1.802776
How to find the mean and standard deviation?Given there is a surprise true/false test with 13 questions.
Thus, the probability of correctly guessing the answer is; p=0.5
Let "X' be the answers correctly guess by a student.
The formula for the binomial probability distribution is;
P(X = x) = nCx * p^(x) * (1 - p)^(n - x)
A) The mean of the binomial distribution is given by the formula;
μ = np
μ = 13 * 0.5
μ = 6.5
The formula for standard deviation is:
σ = √(np(1 - p))
σ = √(13 * 0.5(1 - 0.5))
σ = 1.802776
B) The probability that the student getting at least 11 correctanswers is given by:
P(X ≥ 11) = P(X = 11) + P(X = 12) + P(X = 13)

if two distinct numbers are selected at random from the first seven prime numbers, what is the probability that their sum is an even number? express your answer as a common fraction.
Answers
The probability that a sum is an even number will be 5/7.
What is probability?The area of mathematics known as probability deals with numerical representations of the likelihood that an event will occur or that a proposition is true. An event's probability is a number between 0 and 1, where, roughly speaking, 0 denotes the event's impossibility and 1 denotes certainty. The probability is typically defined as the proportion of favorable outcomes to all outcomes in the sample space. The probability of an event P(E) = (Number of favorable outcomes) is how it is stated (Sample space).So, the first 7 prime numbers:
2,3,5,7,11,13,17Then,
Even numbers are always produced when two odd numbers are added together.Odd numbers are always created when Even numbers are added to Odd numbers.In the list of 7, there is only one even number. If that is one of the options, then the outcome will only be odd.As the same number cannot be chosen twice, there is a 6/7 chance that it won't be chosen the first time and a 5/6 chance that it won't be chosen the second time.By multiplying these two probabilities, we can determine the likelihood of an even sum.

Answers
An nth- degree polynomial function with real coefficient for N = 3 ; 3, 2i are zeros ; f(-1) =20 is given by f(x) = (-1)( x³ -3x²+4x -12).
As given in the question,
Number of zeros of the polynomial function N = 3
Real and complex zeros = 3, 2i , -2i
Function value f(-1) = 20
f(x) = k (x-3)(x-2i)(x+2i)
⇒f(x) = k(x-3)(x²-4i²)
⇒f(x) =k(x-3)(x²+4)
⇒f(-1) = k(-1-3)((-1)² +4)
⇒ 20 =k(-4)(5)
⇒k =-1
Now , f(x) = (-1)((x-3)(x²+4)

Reason:
To shift down 2 units, we go from f(x) = (0.5)x to g(x) = (0.5)x - 2.

Scientific notation is a form of writing a very larger number or very smaller number in a simpler form. The general form of the scientific notation is a number from 1 to 10 is multiplied by a power of 10.
Consider the unknown number as x
The first number = 2×[tex]10^{-6}[/tex]
The result of 2×[tex]10^{-6}[/tex] times x = 6×[tex]10^{-4}[/tex]
So the equation will be
2×[tex]10^{-6}[/tex] × x = 6×[tex]10^{-4}[/tex]
Move 2×[tex]10^{-6}[/tex] to the right hand side of the equation
x = 6×[tex]10^{-4}[/tex] ÷ 2×[tex]10^{-6}[/tex]

domain= (−∞,∞)
Then, range is he set of all representations of domain elements or the set of all function outputs constitutes the range of the function f.
