Answer:
A function f : X → Y is said to be one to one (or injective function), if the images of distinct elements of X under f are distinct, i.e., for every x1 , x2 ∈ X, f(x1 ) = f(x2 ) implies x1 = x2 . Otherwise, it is called many to one function.
Two Forest Ranger stations are located 9.8 miles apart. They both receive the same distress call. They determine that from Ranger Station 1 the distress call is at an angle of 46° and from Ranger Station 2 it is at angle of 52°. Which ranger station is closer to the distress call and by how much?
Answer:
Ranger station 2 is closer by 3.47 miles
Step-by-step explanation:
tan(46)=O/9.8
O (ranger station 2 to distress call)=10.15 miles
sin(46)=9.8/H
H (ranger station 1 to distress call)=13.62 miles
13.62-10.15=3.47 miles
So, ranger station 2 is closer by 3.47 miles

Step-by-step explanation:
On Tuesday, Marissa was $45 short of her fundraising goal. The next day, she was $5 over her goal write an equation to show how much she raised in one day.
Answer: Hello daema, let's let x be the goal and c be the collection per day.
x - 45 + c = x + 5 is the answer so now let's talk about how we did that.
So she wants to get to x which is the goal. But right now she has 45 less than what her goal is. So that would look like this x - 45 now she has to get c or the collection per day to get to her goal. So now it looks like this x - 45 + c. Now that c has to be at least x which is her goal, it now will look like this x - 45 + c = x. But we're not done, the question said that now she 5$ over her goal, or x. So we have to add the + 5 onto the end so now it looks like this x - 45 + c = x + 5. To solve the equation "if you have to" it would be x = 50$ per day.

Devin reads 2 pages of a book every 3 minutes. Which proportion could be solved to find x, the number of minutes it will take to read 6 pages?
Answer: The answer would be 2/3 = x/9
It would take 9 minutes to read 6 pages as per the proportional relationship.
What is proportionality?proportionality is defined as between two or more sets of values, and how these values are related to each other in the sense are they directly proportional or inversely proportional to each other.
Here,
Let y be the number of pages, and x be the time,
According to the quesiton,
x/y = 3 / 2
Now,
Put y = 6
x/6 = 3/2
x = 9 minutes
Thus, it would take 9 minutes to read 6 pages as per the proportional relationship.

Solve the following quadratic equation
(x-18)^2=1.
A. x = 19 and x = 17
B. x = -19 and x = -17
C. x = -19 and x = 17
D. x = 19 and x = -17
To solve the quadratic equation (x - 18)^2 = 1, we can take the square root of both sides and consider the positive and negative roots. Here's how we can proceed:
Taking the square root of both sides gives us:
x - 18 = ±√1
Simplifying the square root of 1, we have:
x - 18 = ±1
Now, let's solve for x by considering both the positive and negative cases:
Case 1: x - 18 = 1
Adding 18 to both sides:
x = 1 + 18
x = 19
Case 2: x - 18 = -1
Adding 18 to both sides:
x = -1 + 18
x = 17
Leading to our final correct answer is:
A. x = 19 and x = 17

Which table represents viable solutions for y = 5x, where x is the number of tickets sold for the school play and y is the amount of money collected for the tickets?
A 2-column table with 4 rows titled School Play Tickets. The first column is labeled tickets (x) with entries negative 100, negative 25, 40, 600. The second column is labeled money collected (y) with entries negative 500, negative 125, 250, 3000.
A 2-column table with 4 rows titled School Play Tickets. The first column is labeled tickets (x) with entries negative 20, 20, 100, 109. The second column is labeled money collected (y) with entries negative 100, 100, 500, 545.
A 2-column table with 4 rows titled School Play Tickets. The first column is labeled tickets (x) with entries 0, 10, 51, 400. The second column is labeled money collected (y) with entries 0, 50, 255, 2000.
A 2-column table with 4 rows titled School Play Tickets. The first column is labeled tickets (x) with entries 5, 65, 80, 200. The second column is labeled money collected (y) with entries 25, 350, 400, 1000.
Third table is true with 4 rows titled School Play Tickets. The first column is labeled tickets (x) with entries 0, 10, 51, 400 and the second column is labeled money collected (y) with entries 0, 50, 255,2000.
Here, the equation is given as;
y = 5x
Where, x is the number of tickets sold for the school play and y is the amount of money collected for the tickets.
What is linear equation?
A linear equation is an algebraic equation of the form y = mx + b
involving only a constant and a first order (linear) term.
Now, we have the following equation;
y = 5 x
For finding the table that complies with this restriction and also have the corresponding values for x and y.
The third table complies with the given condition and has correct values for the given variables;
⇒ x = 0 then y = 0
⇒ x = 10 then y= 50
⇒ x = 51 then y = 255
⇒ x = 400 then y = 2000
Clearly, Third table is true with 4 rows titled School Play Tickets. The first column is labeled tickets (x) with entries 0, 10, 51, 400 and the second column is labeled money collected (y) with entries 0, 50, 255,2000.

Reduced ratios are found by removing (dividing out) the greatest common factor (GCF). For several of these, that factor is the smallest number or the difference between the numbers. Knowledge of multiplication tables is helpful.
9 : 36 = 1 : 4 . . . . common factor of 9
21 : 27 = 7 : 9 . . . . common factor of 3
48 : 72 = 2 : 3 . . . . common factor of 24

10 : 70 = 1 : 7 . . . . common factor of 10

The greatest common factor can be found from your knowledge of multiplication tables and/or divisibility rules. It can also be found using Euclid's algorithm. For that, you ...
Divide the larger number by the smaller and keep the remainder.
If the remainder is 0, the smaller is the GCF.
If the remainder is not zero, replace the larger number with the remainder and repeat from the first step.

21/6 = 3 r 3
6/3 = 2 r 0 . . . . 3 is the GCF of 21 and 27
