I'm going to provide a real life case for this answer. I own and manage an online soccer jersey store and the process behind it is quite simple:
1. Receive order
2. Buy jerseys from supplier
3. Resell at an slighly higher price
4. Pay taxes + shipping
Now, say that "x" is the amount of jerseys my store sells in a month. I can use functions to create an expression that tells me what is the total net revenue I get from selling "x" amount of jerseys a month.
For example, say that the jerseys cost $50 and you sell them for 60$. You also need to pay the shipping for each jersey (say it is $5 per jersey). Then, we can form a function like this:
[tex]y=60x-50x-5x[/tex]
As you can tell, the money that comes back to the seller ($60 dollars per jersey) is expressed as a possitive coefficient for variable "x" (number of sold jerseys). And, all the other costs, which is money that you spend in order to sell the jerseys, are expressed with a negative coefficient meaning that they are not net revenue, it isn't profit. Now, to see how much money you can make by selling 2 jerseys, simplify the function and substitute variable "x" (number of sold jerseys) by 1:
[tex]y=60x-55x\\ \\y=5x[/tex]
Say "y" is the net revenue:
[tex]y=5(2)\\ \\y=10[/tex]
You can also use functions to determine things such as, how many jerseys do I need to sell in order to make $750 of net revenue? In that case you do the following:
[tex](750)=5x\\\\x=\frac{750}{5} \\ \\x=150[/tex]
From this analysis, you can conclude that you need to sell 150 jerseys ij order to amke a net revenue of $750.
In conclusion, linear functions can be used to see how a variable value (normally called "x") can affect in the results in multiple daily situations: how many miles can your car run with a full tank, how much time do I need to work so I can buy a product, how much money I can spend in something so I can have saving of "x" amount at the end of the year, etc...
Toby has a strawberry lace that is 36 cm long ar He needs pieces 18 mm long to decorate a cake. How long is the lace in mm? How many 18 mm pieces can he cut from the lace? help⭐⭐⭐⭐⭐
Answer:
The lace is 36 cm long and 1 cm = 10 mm. So, 36 cm = 360 mm.
He can cut the lace into 18 mm pieces, so he can cut 360 mm / 18 mm = 20 pieces of 18 mm lace from the 36 cm lace.
Suppose I deposit $500 into my bank account that earns 3% interest per year. Is the total amount in my bank account per year a linear relationship? Hint: use a table of values and look at the rate of change. Also, keep in mind that once you earn interest, the next year you will earn interest not only on your original investment but on the new amount.
Answer:
The total amount in your bank account per year is not a linear relationship, it's compound interest.
Step-by-step explanation:
The total amount in your bank account per year is not a linear relationship because it is not a straight line. Linear relationships are defined by an equation in the form of y = mx + b, where m is the slope of the line, x is the independent variable and y is the dependent variable, and b is the y-intercept.
In this case, the total amount in your bank account per year is not a straight line, it is a curve. The total amount in your bank account will increase as a function of time, but the rate of increase is not constant as it is with linear relationships.
The amount of money in your account will increase over time as the interest is compounded. The interest is calculated on the principal + accumulated interest, so the growth rate of the account is not constant, it increases as the balance grows.
For example, the first year you will earn $5000.03 = $15 in interest, and the second year you will earn $5150.03 = $15.45 in interest, the next year the interest will be $530.45*0.03 = $15.91 and so on.
here are 15 European cities that Yolanda would eventually like to visit. On her next vacation, though, she only has time to visit 3 of the cities: one on Monday, one on Tuesday, and one on Wednesday. She is now trying to make a schedule of which city she'll visit on which day. How many different schedules are possible? (Assume that she will not visit a city more than once.)
The number of different schedules are possible is given by the permutation and the equation is P = 2,730 schedules
What are Permutations?A permutation is an ordered arrangement.
The number of ordered arrangements of r objects taken from n unlike objects is:
Permutation ⁿPr = n! / ( n - r )!
Given data ,
Let the total number of schedules be P
Let the total number of European cities be n = 15
Let the number of cities Yolanda can visit in time r = 3 cities
So , the total number of different schedules is calculated by permutation and ,
The total number of different schedules = ⁿPr = n! / ( n - r )!
Substituting the values in the equation , we get
¹⁵P₃ = ( 15 ) ! / ( 15 - 3 ) !
¹⁵P₃ = ( 15 ) ! / ( 12 )!
¹⁵P₃ = 15 x 14 x 13
¹⁵P₃ = 2,730 schedules
Hence , the value of P is 2,730 schedules

Step-by-step explanation:
Step-by-step explanation:
A function assigns the value of each element of one set to the other specific element of another set. The value of the function when the value of x is -4 is 92.
What is a Function?
A function assigns the value of each element of one set to the other specific element of another set.
Given that F(x)=3x²-10x+4, therefore, the value of the function can be calculated by substituting the value of x as -4.
Therefore, the value of the function when the value of x is -4 can be calculated as shown below,
F(x) = 3x² - 10x + 4
F(-4) = 3(-4)² - 10(-4) + 4
= 3(16) + 40 + 4
= 48 + 40 + 4
= 92
Hence, the value of the function when the value of x is -4 is 92.
Square ABCD has a diagonal AC with the given vertices. Find the coordinates of the remaining vertices.
A(-4,-1) and C(2,5)
The coordinates are ( , ) and ( , )
Answer: To find the coordinates of the remaining vertices of square ABCD, we can use the information we have been given about the diagonal AC and its vertices. The diagonal AC has been given as having the vertices A(-4, -1) and C(2, 5). Since a square has right angles, we know that the other two vertices of the square must form a right angle with the diagonal AC.
To find the coordinates of vertex B, we know that it must have the same y-coordinate as vertex A, but a different x-coordinate. Since the x-coordinate of vertex A is -4, we can deduce that the x-coordinate of vertex B must be the same as the x-coordinate of vertex C, which is 2. Therefore, the coordinates of vertex B are (2, -1).
To find the coordinates of vertex D, we know that it must have the same x-coordinate as vertex A, but a different y-coordinate. Since the y-coordinate of vertex A is -1, we can deduce that the y-coordinate of vertex D must be the same as the y-coordinate of vertex C, which is 5. Therefore, the coordinates of vertex D are (-4, 5).
In summary, the coordinates of the remaining vertices of square ABCD are B(2, -1) and D(-4, 5)

A whale-watching tour boat, moving west at a constant speed 45 miles per hour, has finished viewing a whale and is returning to shore. One whale that is right next to the boat swims away in the opposite direction, moving at a constant speed of 25 miles per hour. They swim apart for 35 minutes and then change direction. The boat turns south and again the whale turns in the opposite direction of the boat. They continue moving apart for another 25 minutes. How far apart are the boat and the whale? (Round your answer to the nearest mile).
The boat and the whale are about 218.5 miles apart.
Solving for the distance between the boat and the whale:Using the Pythagorean theorem to calculate the distance between the boat and the whale.
Let's call the distance between the boat and the whale "d" and the time they moved apart "t".
1st movement:
d = 45t
2nd movement:
d = (45t + 25(t+35))²
To calculate the final distance, we need to square d from the second movement and add the result from the first movement.
d² = (45t)² + (25(t+35))²
We know that the boat and the whale were moving apart for 35 minutes and 25 minutes, so we can substitute t = 35 and t = 25 in the equation.
d² = (4535)² + (2560)²
Taking the square root of the result and get the final distance between the boat and the whale.
d = ([tex]\sqrt{4535 ^{2} +2560^{2} }[/tex])
d ≈ 218.5 miles
Hence, the boat and the whale are about 218.5 miles apart.

Number of outcomes desired = 1 (that unlocks the treasure chest)
Therefore, the probability of unlocking the treasure chest
P(T) = Number of outcomes desired/ Total no. of outcomes = 1/6
P(T) is our favorable outcome.
Any other outcome would be unfavorable,
Therefore, the number of unfavorable outcomes would be
= Total no. of outcomes - number of the desired outcomes = 6-1 = 5

Verify that [n+3]!\n!=(n+1
Answer:
To verify that [n+3]! / n! = (n+1), we can use the definition of factorial:
[n+3]! = (n+3) * (n+2) * (n+1) * n!
And we can cancel out n! from both sides of the equation:
(n+3) * (n+2) * (n+1) = n+1
Which is true, and thus [n+3]! / n! = (n+1) holds true.
Another way to verify this is by simplifying the RHS and LHS
(n+1) = (n+1)
And the LHS,
(n+3)! = (n+3)(n+2)(n+1)n! = (n+1)(n+2)(n+3)n! = (n+1)(n+2)(n+3)!/n!
which is also equal to (n+1)
So, [n+3]! / n! = (n+1) is true.

The sum of two numbers is always greater than zero.If one of the numbers is negative, and its absolute value is equal to or greater than the value of the positive number, the result will always be equal to or less than zero.
Counterexample:
-5 + 1 = -4As -4 is less than zero, this proves that the conjecture is false.
Part bGiven conjecture:
The sum of a positive number and a negative number is always positive.If the absolute value of the negative number is greater than the value of the positive number, the result will always be negative.
Counterexample:
2 + (-10) = -8As -8 is negative, this proves that the conjecture is false.
Part cGiven conjecture:
If a figure has four sides, then it is a rectangle.Counterexample:
A scalene trapezium.The interior angles of a rectangle are congruent (90°).
A scalene trapezium has four sides, but as its interior angles are all different, it is not a rectangle. This proves that the conjecture is false.
a car is travelling at 18.1m/s with a constant acceleration of 3.7m/s^2. the car is attempting to pass a truck which is moving at a constant velocity of 29.7m/s. how far in meters must the car travel until it matches the trucks velocity
Answer:
Step-by-step explanation:
?
The car must travel a distance of 130.7 meters. This can be determined by using the equation for distance travelled with a constant acceleration:
Distance = Initial Velocity x Time + (1/2) x Acceleration x Time^2
In this case, the initial velocity is 18.1m/s, the acceleration is 3.7m/s^2, and the final velocity is 29.7m/s. We can set the final velocity equal to the initial velocity and solve for time:
29.7m/s = 18.1m/s + 3.7m/s^2 x Time
Time = 5.4 seconds
We can then plug this value for time into the equation for distance:
Distance = 18.1m/s x 5.4s + (1/2) x 3.7m/s^2 x 5.4s^2
Distance = 130.7 meters

Subtract: 2 1/4 - 1 2/3 =
A) 1 7/12
B) 1/3
C) 5/12
D) 7/12
Answer:
D) 7/12
Step-by-step explanation:
The first thing we want to do is find a like denominator for the fraction
Both 4 and 3 go into the multiple 12, so we'll use that
4x3=12
3x4=12
and what you do to one side, you must do to the other so we have
1/4x3= 3/12
2/3x4= 8/12
With that you get 2 3/12 and 1 8/12, which is subtractable
Take one from 2 so that you can make 3/12 15/12
15/12-8/12=7/12
This gives us our answer 7/12

2 1/4 - 1 2/3
2 1/4 to an improper fraction is 9/4
1 2/3 to an improper fraction is 5/3
to get the same denominator multiply 9/4 by 3 and 5/3 by 4.
27/12 - 20/12
7/12 IS YOUR ANSWER.

At an amusement park, only 17 people are allowed on a ride at the
same time. There are 157 people waiting in line. How many groups
of riders will there be?
Show your work.
Answer:
To find out how many groups of riders there will be, we need to divide the total number of people waiting in line (157) by the maximum number of people allowed on the ride at one time (17).
157 people / 17 people/group = 9.235 groups (approx)
But since the groups must be in whole numbers, we have to round up the value 9.235 groups to the next whole number, which is 10 groups.
So, the number of groups of riders will be 10.
Answer: 9 groups of riders.
Step-by-step explanation:
To find out how many groups of riders there will be, you need to divide the total number of people waiting in line by the maximum number of people allowed on the ride at one time.
157 (total people in line) ÷ 17 (people allowed per ride) = 9.235 (groups of riders)
Because you can't have a fraction of a group, you need to round down to get the whole number of groups.
So the answer is 9 groups of riders.
