Which of the following angles DOES NOT have equal measure when a pair of parallel lines is crossed by a transversal?
Answer: we might have come across different types of lines such as parallel lines, perpendicular lines, intersecting lines, and so on. Apart from that, we have another line called transversal.
This can be observed when a road crosses two or more roads or a railway line crosses several other lines. These give a basic idea of a transversal. Transversals play an important role in establishing whether two or more other lines in the Euclidean plane are parallel.
In this article, you will learn the definition of transversal line, angles made by the transversal with parallel and non-parallel lines with an example.
SOOO in English its LM is the transversal made by the parallel lines PQ and RS such that:
The pair of corresponding angles that are represented with the same letters are equal.
If two parallel lines are cut by a transversal, each pair of alternate interior angles are equal. Transversal property 2

a pound in lukes neighborhood has a depth of 81.6 inches. during the dry season the pond losses an average of 0.02 inches of water each day. luke wrote the function below to represent the depth of the pond in inches x days after the dry season begins. explain lukes error and rewrite the function correctly? f(x) = -0.02(x+81.6)
The correct function to represent the depth of the pond in inches x days after the dry season begins is f(x) = 81.6 - 0.02x
It is a question of functions.
Given that:-
Depth of pond in Luke's neighborhood = 81.6 inches.
Depth that pond loses everyday = 0.02 inches
Function written by Luke to represent the depth of the pond in inches x days after the dry season begins = f(x) = -0.02(x+81.6)
We have to find the error in Luke's function and then rewrite then correct function.
Let x be the number of days after the dry season begins.
We know that,
Depth of pond after x days = Initial depth of pond - (Depth that pond loses everyday)* (number of days after the dry season begins)
Hence, we can write,
f(x) = 81.6 - 0.02x
Luke has wrongly multiplied -0.02 with (x + 81.6) instead of only multiplying with x.

(Edit: This is wrong)
Step-by-step explanation:
Answer:
13/24
hope it helped!!
tell me if you need an explanation
Edit:
Step 1 We can't subtract two fractions with different denominators. So you need to get a common denominator. To do this, you'll multiply the denominators times each other... but the numerators have to change, too. They get multiplied by the other term's denominator. So we multiply 7 by 3, and get 21. Then we multiply 1 by 8, and get 8. Next we give both terms new denominators 8 × 3 = 24. So now our fractions look like this: 21/24−8/24
Step 2 Since our denominators match, we can subtract the numerators. 21 − 8 = 13 So the answer is: 13/24

Step-by-step explanation:
We know that the inverse of sin is cosine. Note, arcsin means the same thing as inverse sin:
sin(ln(2x))Because sin (a) = sin (b) --> a = arcsin (b)
Therefore: ln(2x) = arcsin(y)Solve ln(2x)=arcsin(y) for x(e^arcsin(y))/2Subsitute y = x

find the 9th term of the geometric sequence. 12,36,108,...
The 9th term of the given sequence is 78732.
The given sequence is 12, 36, 108... is a geometric sequence with a common ratio of 3.To find the 9th term of the given sequence, we will use the formula for the nth term of a geometric sequence, which is given by:
aₙ = a₁rⁿ⁻¹
Here, a₁ = 12 and r = 3.
Therefore, the formula for the nth term becomes:
aₙ = 12(3)ⁿ⁻¹
Now, we need to find the 9th term of the sequence. Hence, n = 9. Substituting the values of a₁ and r, and n in the formula, we get:
a₉ = 12(3)⁹⁻¹= 12(3)⁸= 12(6561)= 78732

Kiran surveyed a random sample of students in her school district, and she found these statistics:
P(rides bike to school) = 0.1
P(has crossing guard) = 0.48
P(rides bike and crossing guard) = 0.12
Find the probability that a student rides a bike to school, given that the student's school has a crossing guard.
According to the Random Sample, If a student has a railroad crossing at his school, the probability that the student will bike to school is approximately 0.25.
For two events A and B:
Probability of event A or B occurring =
Probability of event A occurring + Probability of event B occurring - Probability of events A and B occurring at the same time.
This can be written as:
P(A ∪ B) = P(A) + P(B) - P(A ∩B)
Probability chain rule for two events:
For two events A and B:
In the chain rule states that the probability that A and B both occur
P(A ∩ B) = P(A)P(B|A) = P(A)P(A|B)
We know that,
When A is on left , then the probability of both A and B occurring is If term P(A)P(B|A)
and When B is left, B lags behind A in the next term P(B)P(A|B)
P( A|B) = Occurs because the probability B that A does so has already occurred.
and, P(B|A) = Probability of B occurring when A has already occurred.
Using the above convention, we get:
Let event A be a student biking to school.
Let's assume Event B is the crossing guards = 0.48
P(A ∩ B) = P{ride a bicycle and a railroad crossing})=0.12
P(assuming that there is a railroad crossing at the student's school, the student goes to school by bicycle) = P(A | B)
Therefore,
From Probability from the chain Rule:
P(A ∩ B) = P(B) P(A | B)
Therefore,
0.12 = 0.48 × P(A | B)
⇒ P(A | B) = 0.12/0.48
⇒ P(A | B) = 0.25
So, If a student has a railroad crossing at his school, the probability that the student will bike to school is approximately 0.25.

Answer:
Step-by-step explanation:
The length of the third side is ( x - 2 )
Step-by-step explanation:
Volume of a box is the product of its length, width and height.
Volume of box = length × width × height.
One side is (x - 4) and another side is (2x + 1).
These given sides can be either length, height or width.
The volume of a box is given by V = 2x3-11x2 +10x +8. This means each of the sides are factors of the volume. To get the third side, we divide the volume by the product of the two given sides.
Product of the two given sides =
( x-4 ) (2x + 1) = 2x^2 + x - 8x + 4

Note: Answer B is NOT the correct answer. Please find the correct answer. Any answer without justification will be rejected automatically.
The correct answer is option e. The joint probability of two statistical dependent events Y and Z can be written as P(Y and Z) = P(Y) * P(Z|Y).
The concept of joint probability is utilized in probability theory, a statistical tool that investigates the probability of two events happening simultaneously. It is an estimation of the probability of two or more events occurring simultaneously. Joint probability is a method of defining the probability of two events happening at the same time.The joint probability of two statistical dependent events Y and Z can be written as P(Y and Z) = P(Y) * P(Z|Y).This implies that the possibility of Z happening given Y has happened multiplied by the probability of Y happening is the joint probability of Y and Z. P(Z|Y) refers to the probability of Z occurring when Y is true or has already occurred. It is conditional probability and is often used to calculate joint probabilities.The formula for conditional probability is P(A|B) = P(A and B)/P(B), which can be simplified to P(A and B) = P(A|B) * P(B). This formula is applicable to P(Y and Z), where P(Y and Z) = P(Z|Y) * P(Y).

(Please make answer simple yet reasonable. Thank you for answering, have a blessed day everyone! I am thankful to have people to help and support me.)
By using trigonometric relations we will see that the area is:
\(A = h*tan(60\°)*/2 = tan(60\°)*h^2/2\)
How to find the area of one triangular section?
Remember that the area of a right triangle is equal to the product between the cathetus divided by 2.
Sadly, here we don't have the measures of any sides of the triangle, so getting the actual area is impossible, but if we assume that some dimension is given (like the height, let's say that is h).
h is the cathetus adjacent to the 60° angle, then the other cathetus (the bottom one) is given by:
tan(60°) = x/h
x = tan(60°)*h
Then our two catheti are h and tan(60°)*h.
This means that the area will be:
\(A = h*tan(60\°)*/2 = tan(60\°)*h^2/2\)
Here we only used trigonometric properties, so this area will work for any height given (always that the value of h is the cathetus adjacent to the 60° angle).

Which expression is equivalent to StartRoot 8 x Superscript 7 Baseline y Superscript 8 Baseline EndRoot? Assume x greater-than-or-equal-to 0.
x y squared StartRoot 8 x cubed EndRoot
2 x cubed y cubed StartRoot x y squared EndRoot
2 x cubed y Superscript 4 Baseline StartRoot 2 x EndRoot
4 x cubed y Superscript 4 Baseline StartRoot x EndRoot
The expression that is equivalent to StartRoot \(8 x^7 y^8\) EndRoot is (\(2 x^3 y^4\) StartRoot 2 x EndRoot)^2.
To understand why this is the case, let's break down each expression and simplify them step by step:
StartRoot \(8 x^7 y^8\) EndRoot:
We can rewrite 8 as \(2^3\), and since the square root can be split over multiplication, we have StartRoot \((2^3) x^7 y^8\) EndRoot. Applying the exponent rule for square roots, we get StartRoot \(2^3\) EndRoot StartRoot \(x^7\) EndRoot StartRoot \(y^8\) EndRoot.
Simplifying further, we have 2 StartRoot \(2 x^3 y^4\) EndRoot StartRoot \(2^2\) EndRoot StartRoot \(x^2\) EndRoot StartRoot \(y^4\) EndRoot. Finally, we obtain 2 \(x^3 y^4\) StartRoot 2 x EndRoot, which is the expression in question.
(\(2 x y^2\) StartRoot 8 x^3 EndRoot)^2:
Expanding the expression inside the parentheses, we have \(2 x y^2\)StartRoot \((2^3) x^3\) EndRoot. Applying the exponent rule for square roots, we get \(2 x y^2\) StartRoot \(2^3\) EndRoot StartRoot \(x^3\) EndRoot.
Simplifying further, we have \(2 x y^2\) StartRoot 2 x EndRoot. Squaring the entire expression, we obtain (\(2 x y^2\) StartRoot 2 x EndRoot)^2.
Therefore, the expression (\(2 x^3 y^4\) StartRoot 2 x EndRoot)^2 is equivalent to StartRoot \(8 x^7 y^8\) EndRoot.
