Answer:

the answer is to the question is 12

The function represents the domain of a function is x ≥ -2.

What is a graph of a quadratic function?

A graph of a quadratic function is a type of parabola, which is a symmetric, U-shaped curve that opens either upward or downward. The equation of a quadratic function is y = ax² + bx + c, where x and y are variables, and a, b, and c are constants.

The graph of a quadratic function is determined by the value of the coefficient a. If a is positive, the parabola opens upward, and if a is negative, the parabola opens downward. The vertex of the parabola is the highest or lowest point on the graph and it is the point of symmetry of the parabola. The x-coordinate of the vertex is given by -b/(2a) and the y-coordinate of the vertex is given by the value of the function at that point.

In the given figure, we can see that it is a parabola, and if we look towards the options, then the third option is a domain of the given function

x ≥ -2

So we can say this is the perfect match for the given figure.

Hence, the function represents the domain of a function is x ≥ -2.

Answer:

No. The relation shows indirect variation.

Step-by-step explanation:

      In this relation the absolute value of one variable increases while the other gets decreased.

xy = k

  [tex]\sf x = \dfrac{k}{y}[/tex]

Here, xy = 3

           [tex]\sf x = \dfrac{3}{y}[/tex]

So, if the product of two variables is constant, then it is indirect or inverse variation.

a) A linear equation that describes the relationship between the number of buses and the number of vans needed for 120 students is 24x + 8y = 120.

b) If the teachers rent 4 buses, the number of vans they will need to transport all the students is 3.

c) If the teachers rent 6 vans, the number of buses they will need to transport all the students is 3.

d) If the teachers rent only vans, the number of vans needed will be 15.

e) Suppose the teachers rented only buses, the number of buses needed will be 5.

A linear equation is an algebraic equation of the form y = mx+b.

A linear equation involves a constant and a first-order (linear) term, with m as the slope and b as the y-intercept.

The total number of students on the field trip = 120

The number of students a bus can seat = 24

The number of students a van can seat = 8

Let the number of buses = x and the number of vans = y

24x + 8y = 120

b) Renting 4 buses, the number of vans needed:

24(4) + 8y = 120

96 + 8y = 120

8y = 24

y = 3

c) Renting 6 vans, the number of buses will be:

24x + 8(6) = 120

24x = 48 = 120

24x = 72

x = 3

d) Renting only vans, the number needed will be:

24(0) + 8y = 120

8y = 120

y = 15

e) Renting only buses, the number needed will be:

24x + 8(0) = 120

24x = 120

x = 5

Everything above 5 goes to the next tenth. Example:

17 = 20

Everything below 5 goes to the next below tenth. Example:

13 = 10

You get it or more expantion?

The solution to the inequality:

(1/2)*|x + 1| ≤ 6

is:

x ≤  11 or x ≥  -13

Here we want to solve the inequality below:

(1/2)*|x + 1| ≤ 6

To solve it we need to isolate x, so let's start by multiplying both sides by 2:

2*(1/2)*|x + 1| ≤ 2*6

|x + 1| ≤ 12

Now we can break the absolute value part into two inequalities:

(x + 1) ≤ 12

(x + 1) ≥ -12

Solving these two we will get:

x ≤ 12 - 1 = 11

x ≥ -12 -1 = -13

That is the solution.

There are 55 adults and 27 younglings attended the club.

let the number of adults attended the club be x

let the number of younglings  attended the club be y

total people attended the club = 82

so,

x + y = 82.....[1]

cost for the adult = $6

cost for the younglings = $4

so total amount collected = $438

so, equation formed is ,

6x + 4y = 438.......[2]

from equation [1]

x + y = 82

x = 82 - y

put this in equation [2]

6(82 - y) + 4y = 438

492 - 6y + 4y = 438

492 - 2y = 438

492 - 438 = 2y

2y = 54

y = 27

put this value in equation [1]

For the energy use to double it will take approximately 69.66 years.

To find out how many years it will take for the energy use to double, we can use the formula for exponential growth:

P = P₀ * (1 + r)^t

where P is the final amount of energy use, P₀ is the initial amount of energy use, r is the growth rate (1% per year in this case), and t is the number of years.

Setting P = 2 * P₀ and solving for t, we get:

2 * P₀ = P₀ * (1 + r)^t

Dividing both sides by P₀:

2 = (1 + r)^t

Taking the natural logarithm of both sides:

ln(2) = t * ln(1 + r)

Dividing both sides by ln(1 + r):

t = ln(2) / ln(1 + r)

Plugging in the values for r = 0.01 and using the natural logarithm function, we get:

t = ln(2) / ln(1 + 0.01) = 69.66 years

So it will take approximately 69.66 years for the energy use to double.

The slope of the line is 0.93 and the y intercept is 100.54

Value of tempareture at time 30 mins = 1/2 hr = 101.01°

Value of tempareture at 1 hr is = 101.47°

Value of temperature at 90 mins  =1.5 hr = 101.935°

An equation is a formula that uses the equals sign to connect two expressions to show that they are equal.

A line's slope is how steeply it slopes from LEFT to RIGHT. The slope of a line is determined by dividing its rise, or vertical change, by its run, or horizontal change.

The range of values that we are permitted to enter into our function is known as the domain of a function. The x values for a function like f make up this set (x). A function's range is the collection of values it may take as input. After we enter an x value, the function outputs this sequence of values.

The collection of all a function's outputs is its range. Example: Let's have a look at the function f: A - > B, where f(x) = 2x and A and B each represent a "collection of natural numbers." The domain in this instance is A, and the co-domain is B. The range then appears as the function's output.

As per the problem

at starting that is x =0 hrs The temperature y = 99.9°

at x = 10/60 = 1/6 , y = 100.7° and at x = 2 , y = 102.4°

The equation of the line is

y-y₁ = (y₂ - y₁)/(x₂ - x₁) * (x - x₁)

(y - 100.7) = (102.4 - 100.7)/(2 - 1/6) * (x - 1/6)

y = 0.93x + 100.54

The slope of the line is 0.93 and the y intercept is 100.54

Value of tempareture at time 30 mins = 1/2 hr = 101.01°

Value of tempareture at 1 hr is = 101.47°

Value of temperature at 90 mins  =1.5 hr = 101.935°

Temperature at 4 hrs past current time  = 104.26°

The domain of the function will be the time which can go upto infinite.

Regardless of the sign, a modulus function returns the magnitude of a number. The absolute value function is another name for it.

It always gives a non-negative value of any number or variable. Modulus function is denoted as y = |x| or f(x) = |x|, where f: R → (0,∞) and x ∈ R.

The value of the modulus function is always non-negative. If f(x) is a modulus function , then we have:

If x is positive, then f(x) = x

If x = 0, then f(x) = 0

If x < 0, then f(x) = -x

Given data ,

Let the modulus function be represented as A

Now , the equation will be

The amount James borrowed from Rita or Rita borrowed from James = $ 12

And , Let x be the amount of money James will have after he sees Rita

The amount of money with James in his wallet = $ 48

So ,

x = 42.80 - 12

On subtracting 42.80 on both sides of the equation , we get

x - 42.80 = -12   be equation (1)

And , when James receives the amount from Rita , the equation is

x = 42.80 + 12

So, there are 56 different committees possible, of 3 people, that could be elected to attend a political national convention from a ballot of 8 names.

When choosing a committee of 3 people from a group of 8 names, the order in which the names are chosen does not matter and repetition is not allowed, this is an example of a combination.

The number of different committees possible is given by the binomial coefficient (n choose k) where n is the number of items to choose from (in this case, 8 names) and k is the number of items to choose (in this case, 3 names for the committee).

The binomial coefficient is calculated as:

n!/(k!(n-k)!)

where ! denotes the factorial operator, meaning the product of all positive integers up to that number.

So in this case, the number of different committees possible is (8!/(3!(8-3)!) = 8!/(3!5!) = (876)/(321) = 56.
