Relation 2 and 3 are actual functions with proper domain, co domain, range.

A function can be represented in several ways, including using algebraic expressions, tables, graphs, or even words. For example, the function f(x) = 2x + 1 defines a relationship between the input x and the output 2x + 1. If we input x = 3 into this function, the output would be f(3) = 2(3) + 1 = 7.

Functions can have different properties, such as being continuous or discontinuous, being differentiable or nondifferentiable, or having maximum or minimum values. Functions can also be classified according to their types, such as linear, quadratic, exponential, logarithmic, trigonometric, or piecewise-defined functions.

Functions are used extensively in mathematics, science, engineering, economics, and many other fields to describe real-world phenomena and to solve practical problems. They are also studied in their own right, as objects of mathematical interest and beauty, with deep connections to many other areas of mathematics, such as calculus, analysis, and algebra

By using the concept of compound interest, the total amount is $4063.27.

We have,

The amount that was deposited during high school graduation = $1000

The amount that was deposited during college graduation after 4 years = $2000

The total number of years elapsed = 5 years

The interest rate per annum (p.a.) = 4%

The simple Interest (SI) formula is given by,

SI = P × r × t

where, P = Principal amount

r = Rate of interest

t = Time period

Compound Interest (CI) formula is given by,

CI = P (1 + (r/n))^(nt)

Where P = Principal amount

r = Rate of interest

t = Time period

n = Number of times interest is compounded

For the total amount using compound interest.

Total amount (A) = Principal + Compound interest

A = P + CI

Implying it to our data, we get the following.

For $1000 that was deposited during high school graduation,

For 5 years, n = 1, t = 5 years, r = 4% p.a.

CI = 1000[1+(4/100)]^(1×5)

CI = 1000[1+(1/25)]^5

CI = 1000×(26/25)^5

CI = 1000×1.21665

CI = $1216.65

For $2000 that was deposited during college graduation after 4 years,

The total number of years elapsed = 5 years + 4 years = 9 years

n = 1, t = 9 years, r = 4% p.a.

CI = 2000[1+(4/100)]^(1×9)

CI = 2000[1+(1/25)]^9

CI = 2000×(26/25)^9

CI = 2000×1.4233

CI = $2846.62

Therefore, the total amount (A) is $1216.65 + $2846.62 ⇒ $4063.27.

When x is the subject of the formula a/b = 2x/x+5, the value of x = 5a/(2b - a).

The alphabetic letter that conveys a numerical value or a number is known as a variable in mathematics. A variable is used to represent an unknown quantity in algebraic equations.

Any alphabet from a to z can be used for these variables. Most frequently, the variables "a," "b," "c," "x," "y," and "z" are utilised in equations. By performing mathematical operations on variables as if they were express numbers, one is able to handle a variety of problems in a single computation. A quadratic recipe is a common example that demonstrates how to explain each quadratic condition by simply substituting the numerical estimates of the condition's coefficients for the variables that correspond to it.

The given formula is:

a/b = 2x/x+5

To make x the subject of the formula we have to isolate the value of x.

Using cross multiplication we have:

a(x + 5) = b(2x)

ax + 5a = 2bx

5a = 2bx - ax

5a = x (2b - a)

5a/(2b - a) = x

Hence, when x is the subject of the formula a/b = 2x/x+5, the value of x = 5a/(2b - a).

We can sketch the graph of 2x²+4x.

We can start by dissecting the equation and identifying its main components before drawing the graph of 2x²+4x.

The formula reads as y = ax² + bx + c, where a = 2, b = 4, and c = 0. It is a quadratic function.

The upward opening of the graph is indicated by the positive coefficient of x2 (a). By applying the formula -b/2a, which in this case equals -4/4 = -1, one can determine the vertex of the parabola.

Hence, the parabola's vertex is located at (-1,0).

By setting y = 0 and solving for x, we may get the graph's x-intercepts:

0 = 2x² + 4x

0 = 2x(x + 2)

Hence the x-intercepts are at x = 0 and x = -2.

We can set x = 0 to determine the graph's y-intercept:

y = 2(0)² + 4(0) = 0

The y-intercept is therefore at (0,0).

Using this knowledge, we can draw the 2x²+4x graph as follows:

Vertex located at (-1,0).

x = 0 and x = -2 are the two x-intercepts.

Y-intercept is located at (0,0).

The graph has a "U"-shaped opening that faces upward.

We can confirm that each person should receive exactly 224 Pokémon cards, and there won't be any cards left over.

To split the 1,792 Pokémon cards equally between 8 people, including yourself and your 7 friends, you need to divide the total number of cards by the number of people:

1,792 cards ÷ 8 people = 224 cards per person.

So each person should get 224 Pokémon cards.

However, we should also check if there is a remainder after the division. To do that, we can multiply the number of cards each person is getting by the number of people and subtract it from the total number of cards:

224 cards/person x 8 people = 1,792 cards

1,792 cards - 1,792 cards = 0 remainder

If a person tosses a coin 9 times, there are 84 ways in which a person can get 6 heads in 9 coin tosses.

When a person tosses a coin 9 times, there are two possible outcomes for each toss - either heads or tails. Hence, there are a total of 2^9 = 512 possible outcomes for 9 coin tosses.

To find the number of ways in which a person can get 6 heads, we need to consider the number of ways in which 6 heads can occur in the 9 coin tosses, while the remaining 3 tosses can result in tails. The number of ways in which 6 heads can occur in 9 tosses is given by the binomial coefficient C(9,6), which is equal to 84.

Hence, there are 84 ways in which a person can get 6 heads in 9 coin tosses. This can be calculated using the formula for binomial coefficients:

C(9,6) = 9!/(6!3!) = (987)/(321) = 84

Alternatively, we can also calculate this using a combination of multiplication and addition. We can choose any 6 out of the 9 coin tosses to result in heads, which can be done in C(9,6) ways.

For each of these ways, the remaining 3 coin tosses will result in tails, which can occur in only one way. Hence, the total number of ways in which a person can get 6 heads in 9 coin tosses is given by:

The probability of the complement of choosing an orange juice box is 17/18. (option d)

The complement of an event is the probability of that event not occurring. In this case, the event is choosing an orange juice box, so the complement is choosing any other juice box (i.e., an apple juice box or a fruit punch juice box).

The total number of juice boxes in the cooler is:

4 + 8 + 6 = 18

The number of juice boxes that are not orange juice boxes is:

4 + 6 = 10

Therefore, the probability of choosing a juice box that is not an orange juice box (i.e., the complement of choosing an orange juice box) is:

10/18 = 5/9

But the question asks for the probability of the complement, which is the probability of not choosing a juice box that is not an orange juice box. This is simply:

1 - 5/9 = 4/9

However, the question asks for the probability of the complement of choosing an orange juice box, not the complement of not choosing an orange juice box. These two probabilities are equal, since the event and its complement always add up to 1. Therefore, the probability of the complement of choosing an orange juice box is:

It takes Martha `4` hours to knit each hat and `13` hours to knit each pair of mittens.

What is meant by hours?

Hours are a unit of time used to measure the duration of an event or activity. An hour is equal to 60 minutes or 3,600 seconds. It is often used to indicate the time of day or to schedule appointments or events.

What is a pair?

A pair is a set of two things that go together or belong together, like a pair of shoes, socks, or gloves. It can also refer to a pair, a duo, or a twosome.

According to the given question

Let's assume that each hat takes `h` hours to knit and each pair of mittens takes `m` hours to knit.

From the given information, we know that:

- 3 hats and 3 pairs of mittens took a total of 51 hours. This means that 3h + 3m = 51.

- 3 hats and 5 pairs of mittens took a total of 77 hours. This means that 3h + 5m = 77.

We can use these two equations to solve for `h` and `m`.

First, let's solve for `h` by multiplying the first equation by 5 and the second equation by 3, and then subtracting the second equation from the first:

15h + 15m = 255

9h + 15m = 231

-----------------

6h = 24

h = 4

So each hat takes Martha `4` hours to knit.

Now we can use either of the original equations to solve for `m`. Let's use the first one:

3h + 3m = 51

3(4) + 3m = 51

12 + 3m = 51

3m = 39

m = 13

Step-by-step explanation:

If P represents the number of pounds of your package, and C is the total cost of shipping your package, the equation that represents the relationship between P and C is C = 3 + 0.63P.

To write an equation that represents the relationship between the weight of the package (P) and the total cost of shipping (C), we need to use the information given in the problem. The shipping company charges a fixed base cost of $3 per package plus an additional $0.63 per pound.

We can represent the additional cost per pound as 0.63P, since the cost increases by $0.63 for every additional pound. Therefore, the equation that represents the relationship between P and C is:

C = 3 + 0.63P

This equation gives us the total cost of shipping a package based on its weight. We can use this equation to calculate the cost of shipping a package of any weight by simply plugging in the weight (in pounds) for P and then solving for C.

For example, if a package weighs 5 pounds, we can substitute P = 5 into the equation to get:

C = 3 + 0.63(5)

C = 3 + 3.15
