The range of the function f(x) = 5 -10x for domain {-1, 2, 4}  is { 15, -15, -35}

A function's domain and range are its constituent parts. Range, Domain, and Function. A is the domain and B is the co-domain if a function f: A B exists that maps every element of A to an element in B. 'b', where (a,b) R, provides the representation of an element 'a' under a relation R. The collection of photos is the function's range. In general, a function's domain and range are denoted as follows:

Domain(f) = {x ∈ R} and range(f)={f(x) : x ∈ domain(f)}

"All the values" that are input into a function are referred to as the domain of a function. The collection of all potential inputs for a function is its domain. Think of this box as the f(x) = 2x function. The domain is only the collection of natural numbers when the input values are x = 1,2,3,4,..., and the values that are returned are referred to as the range. However, f(x) = 2x is often defined for all real values of x, and as a result, its domain is the set of all real numbers, which is represented by  (-∞, ∞). The general formulae for determining the domain of various types of functions are listed below. The set of all real numbers, or R, is used here.

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. Set of even natural numbers is the range. The components of the co-domain that are mapped are known as the pictures, while the elements of the domain are known as pre-images. The set of all pictures of the domain's elements in this case serves as the function's range, as does the set of all of its outputs.

Domain of the function x = {-1,2,4}

The function is  f(x) = 5 - 10x

range when x = -1

f(x) = 5 - 10*(-1) = 15

when x = 2

f(x) = 5 - 10* 2 = -15

and x= 4

f(x) = 5 - 10*4 = -35

The range of the function for domain {-1, 2, 4}  is { 15, -15, -35}.

What is Domain and Range of a function ?

The domain of a function is the set of all possible inputs for the function. It is the set of all x-values which will make the function "work", and will output real y-values. The range of a function is the set of all possible outputs of the function. It is the set of all y-values which can be produced by the function for the given set of x-values. In other words, it is the set of values that result when the function is applied to all the elements of the domain. In order for a function to be defined, both the domain and the range must be specified.

Answer:

the price of an adult ticket is $8, and the price of a child ticket is $14.

Step-by-step explanation:

To find the price of an adult ticket and the price of a child ticket, we need to set up a system of equations. Let "A" represent the price of an adult ticket and "C" represent the price of a child ticket.

On the first day, the school sold 3 adult tickets and 1 child ticket for a total of $38, so we can set up the following equation to represent this information:

3A + C = 38

On the second day, the school took in $104 by selling 6 adult tickets and 4 child tickets, so we can set up the following equation to represent this information:

6A + 4C = 104

Now that we have our two equations, we can solve for the values of A and C. We can use the elimination method to solve this system of equations. To do this, we need to multiply one of the equations by a constant so that one of the variables has the same coefficient in both equations. We'll multiply the first equation by 2:

6A + 2C = 76

We can then subtract this equation from the second equation to eliminate the C term:

6A + 4C - 6A - 2C = 104 - 76

This simplifies to:

0A + 2C = 28

Dividing both sides by 2, we get:

C = 14

We can now substitute this value for C in one of our original equations and solve for A. We'll use the first equation:

3A + 14 = 38

Subtracting 14 from both sides, we get:

3A = 24

Dividing both sides by 3, we get:

A = 8

Therefore, the price of an adult ticket is $8, and the price of a child ticket is $14.

The level in the pot rising when the coffee in the cone is 5 in deep is 0.35 in/min.

Here the variables are the height of the coffee in the filter hf , the radius of the top of the coffee in the filter rf , and the height of the coffee in the pot hp:

We allowed Vp to represent the volume of coffee in the pot. We are interested in the instant when

hf = 5 in and dVp/dt = 10 in³/min.

The question is dhp/dt =? when dVp/dt = 10 in³/min and hf = 5 in

We need to relate hp to the other variables. In the pot (idealized as a cylinder), we have the volume Vp as Vp = π(3)²hp = 9πhp in³(since the volume of a cylinder of radius r and height h is V = πr²h).

Differentiation of Vp with respect to time gives dVp/dt = 9πhp/dt or

dhp/dt = (1/9π).(dVp/dt)

When dVp/dt = 10 in³/min and hf = 5 in, we have

dhp/ dt = 1/9π(10)

= 10/9π in/min

dhp/ dt ≈ 0.35 in/min (notice that the answer here is independent of hf ).

Hence, the level in the pot rising when the coffee in the cone is 5 in deep is 0.35 in/min.

The coach can select the players in 1081575 ways .

A combination is a technique for finding the number of possible arrangements in a set of items where the order of the selection is irrelevant. .

The formula for determining the number of possible arrangements by selecting only a few objects from a set with no repetition is expressed mathematically as follows:

[tex]nC_r=\frac{n!}{r!(n-r)!}[/tex]

Where:n denotes the total number of elements in a set,

k denotes the number of selected objects

! - the factorial

Factorial (noted as "!") is the sum of all positive integers that are less than or equal to the number preceding the factorial sign.

For instance, [tex]3! = 1 * 2 * 3 = 6[/tex].

Given,

Total number of players,n = 25

Number of selected players,r = 8

Number of ways that players are selected is determined by,

[tex]25C_8=\frac{25!}{8!(25-8)!}\\\\=\frac{15511210043330985984000000}{(40320)*(355687428096000)}\\\\=1081575[/tex]

Answer: 15,000

Step-by-step explanation:

For a quadratic function f(x) = ax² + bx + c, we can find the minimum and maximum value using the formula -b/2a or by graphing the function.

We know that the general form of quadratic function is f(x) = ax² + bx + c ; a ≠ 0

The graph of quadratic function is a parabola. The graph is parabola that either opens upward or downward.

For a quadratic function is f(x) = ax² + bx + c,

if a is positive (a > 0) then the parabola opens upward.

In this case you will be finding the minimum value of f(x) at the vertex of parabola.

if a is negative (a < 0), then the parabola opens downward.

In this case you will find its maximum value of f(x) at the vertex of parabola.

Also, the value of -b/2a will tell you the minimum or maximum value of f(x) which is the vertex of the parabola.

Therefore, to find the minimum and maximum of a quadratic function f(x) = ax² + bx + c :

1) find vertex of function from the graph

Answer:

10. Given a, b E Z, if a²(b² - 2b) is odd, then both a and b must be odd numbers. This is because the only way for the product of two numbers to be odd is if both of the numbers are odd. In other words, if a and b are both even, then a²(b² - 2b) would be an even number, and if one of a and b is odd and the other is even, then a²(b² - 2b) would be an even number. So the only way for a²(b² - 2b) to be odd is if both a and b are odd.

11. Given m, n E Z, if 25 + mn is divisible by 5, then either m or n must be divisible by 5. This is because if both m and n are not divisible by 5, then the product mn will not be divisible by 5, and 25 + mn would not be divisible by 5. However, if either m or n is divisible by 5, then the product mn will be divisible by 5, and 25 + mn would be divisible by 5. So if 25 + mn is divisible by 5, then either m or n must be divisible by 5.

12. If m, n E Z and m + n is even, then m² + n² is also even. This is because the sum of two even numbers is always even, and the square of an even number is always even. So if m + n is even, then both m and n must be even, and m² and n² would both be even. Therefore, the sum m² + n² is also even.

13. An integer n is even if and only if n² + 2n + 9 is odd. This is because the square of an even number is always even, and the sum of two even numbers is always even. So if n is even, then n² and 2n are both even, and the sum n² + 2n + 9 would be odd. On the other hand, if n² + 2n + 9 is odd, then the sum of the first two terms, n² + 2n, must be even. Since the square of an even number is always even, this means that n must be even. So n is even if and only if n² + 2n + 9 is odd.

14. If a is an odd integer, then a² + 3a + 5 is also odd. This is because the product of two odd numbers is always odd, and the sum of two odd numbers is always even. So if a is odd, then a² and 3a are both odd, and the sum a² + 3a + 5 would be even. Since the sum of two odd numbers is always even, this means that a² + 3a + 5 is odd. Therefore, if a is an odd integer, then a² + 3a + 5 is also odd.

The greatest whole number possible length for the given measures of triangle is 23 cm.

As given in the question,

Measure of two side-length of a given triangle are :

Let 'x' be the side length = 8.5cm

And 'y' be the side length = 15cm

'z' be the side length of the third side of a triangle.

Sum of two sides is greater than third side and difference of two sides is smaller than the third side.

y - x < z < y + x

⇒ 15 - 8.5 < z < 15 + 8.5

⇒ 6.5 cm < z < 23.5cm

Greatest whole number representing length of the third side of a triangle is  less than 23.5 .

Based on the triangle inequality theorem, the list that could not be the measures of lengths of the three sides of a give triangle is: D. 12 yd, 35 yd, 20 yd.

The triangle inequality theorem expresses the relationship between the three lengths of sides that can form a triangle. If the sides are are a, b, and c, it states that:

a + b > c

a + c > b

c + b > a.

Considering this set of three sides, 5cm, 12 cm, 15 cm, we have:

5 + 12 > 15

17 > 15 [true]

5 + 15 > 12

20 > 12 [true]
