The relationship is not functional

In the table, students 1 and 3 are having the same output. Therefore, a table cannot be a function if there are two inputs that have the same output.

Thus, the relationship between the students and the tickets sold is not a function A function is a relation in which one input can have only one output.

Let the students be = x

Let the number of tickets sold by the student be = y

Thus, from the table, it can be inferred -

Student 1 and student 3 are having the same number of outputs meaning that the number of tickets sold by student 1 and student 3 is the same.

Thus,

There is no function between the students and the number of tickets sold.

The inverse function returns the original value for which the output of a function was given.

[tex]y^{-1}[/tex] = -1 ± √(x - 5) /2 be the inverse the function y = (1 - 2x)² + 5.

The inverse function returns the original value for which the output of a function was given. When it comes to functions, f and g are inverse, with f(g(x)) = g(f(x)) = x. A function that is made up of its inverse returns the original value. The inverse of f is then g(y) = (y - 5)/2 = x.

An inverse in mathematics is a function that serves to "undo" another function. That is, if f(x) produces y, then putting y into the inverse of f yields x. Invertible functions are those that have an inverse, which is denoted by f1.

Let the equation be y = (1 - 2x)² + 5

simplifying the above equation, we get

√(x - 5) y = (1 - 2x)² + 5

x = (1 - 2y)² + 5

The function of x be x = (1 - 2y)² + 5

x - 5 = (1 - 2x)²

± √(x - 5) = (1 - 2y)

± √(x - 5) - 1 = 2y

Divide both sides of the equation by 2, we get

[± √(x - 5) - 1]/2 = 2y/2

[± √(x - 5) -1] /2 = y

[tex]y^{-1}[/tex] = -1 ± √(x - 5) /2

Therefore, the inverse of the function be [tex]y^{-1}[/tex] = -1 ± √(x - 5) /2.

When the product of a number m and 1.7 is 6.63 the required value of m is 3.9

In mathematics, an equation is a formula that expresses the equality of two expressions by connecting them with the equal sign = .

Now the given statement is,

The product of a number m and 1.7 is 6.63

Thus, converting it into numerical form we get,

1.7m = 6.63

Dividing both the side by 1.7 we get,

1.7m/1.7 = 6.63/1.7

Solving we get,

m = 3.9

this is the required value of m.

Thus, when the product of a number m and 1.7 is 6.63 the required value of m is 3.9

The geometric probability that Juan will score more than 0 points = 0.785

Juan's game board consists of a square with a circle inscribed in it.

If he hits the circle, then he can score more than 0 points.

Length of side of the square = 50 cm

So area of the square = 50 x 50 = 2500 square cm.

Now the area of the large circle = 1963.5 square cm.

Geometric probability that Juan will score more than 0 points

                              = Area  of the circle / Area of the square

The answer to the given logarithm expression is log₄₉7  = 1/2

Another technique to clarify exponents in mathematics is through logarithms. A base number's logarithm equals another number.

For instance, log10 100 = 2 if 102 = 100. A logarithm is defined as an influence by which variety must be raised to receive another value. this is often the foremost convenient thanks to represent large numbers. Logarithms have several important properties that prove that logarithmic multiplication and division is written because the logarithm of addition and subtraction. The log is named the logarithm of base e. The logarithm is represented by ln or loge. where 'e' represents Euler's constant,  approximately capable 2.71828. as an example, the log of 76 is written as ln 76. The log defines what percentage times 'e' must be multiplied to induce the required output.

We need to evaluate log₄₉7

Using Property

logₙ (a) = 1 / logₐ (n)

log₄₉7 = 1/ log₇ 49

Using the properties of log again logₐ (mⁿ) = n logₐ m

49 = 7²log₇ 49

can be written as

log₇ 49 = 2 log₇ 7

We know that logₐ a = 12 log₇ 7= 2

Value of log₄₉7 = 1/ log₇ 49= 1/ 2 log₇ 7= 1/2

Hence,  we evaluated the logarithm which is log₄₉7  = 1/2

f(4) means what is the value of f(x) when x = 4

substitute x = 4 into f(x)

f(4) = 2(4) - 5 = 8 - 5= 3

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

2

substitute x = - 1 into g(x)

g(- 1) = 3(- 1)² + 5 = 3(1) + 5 = 3 + 5 = 8

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

3

substitute x = 4 into h(x)

h(4) = 3(4) + 2 = 12 + 2 = 14

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

4

(f + g)(- 2)

= f(- 2) + g(- 2)

= 2(- 2) - 5 + 3(- 2)² + 5

= - 4 - 5 + 3(4) + 5

= - 9 + 12 + 5

= - 9 + 17

= 8

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

5

(f + h)(2)

= f(2) + h(2)

= 2(2) - 5 + 3(2) + 2

= 4 - 5 + 6 + 2

= - 1 + 8

= 7

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

6

(f - g)(- 3)

= f(- 3) - g(- 3)

= 2(- 3) - 5 - (3(- 3)² + 5)

= - 6 - 5 - (  3(9) + 5)

= - 11 - ( 27 + 5)

= - 11 - ( 32)

= - 11 - 32

= - 43

The expanded form of 3(2x -3y -2) is given by the equation 6x -9y -6

The equation given is a linear equation in two variables and to simplify the equation 3(2x -3y -2), we need to use algebraic properties

The algebraic property used here is distributive property which says that a (b+ c) = ab + ac.

So, let us expand the equation using the algebraic property mentioned above

As a= 3, b=2x and c=3y+2

  3(2x -3y -2)

  3 (2x) -3(3y+2)

Using the property again with a=3, b=3y and c=2

     3 (2x) -3(3y+2)

     6x -3(3y) -3(2)

     6x - 9y -6

Hence, the expanded form of 3(2x -3y -2) is given by the equation 6x -9y -6
