Yes , the given function is an inverse function which is given by  [tex]f^{-1}(y)=\frac{y-2}{\sqrt{2} }[/tex] .

We have given a function [tex]f(x)=x\sqrt{2} -1+3[/tex] .        ....(1)

On simplifying the equation we, get

     [tex]f(x)=x\sqrt{2} +2[/tex]

Let y = f(x)

      [tex]y=x\sqrt{2} +2\\\\y-2=x\sqrt{2}\\\\x=\frac{y-2}{\sqrt{2} }[/tex]           ......(2)

Swap the values of x and y, then the inverse is then

     [tex]x=f^{-1}(y)[/tex]     ...(3)

Comparing equation (2) and (3) , we get

  [tex]f^{-1}(y)=\frac{y-2}{\sqrt{2} }[/tex]

We can check that this is really an inverse function or not

Putting [tex]x=f^{-1}[/tex] in equation (1) , we get

   [tex]f(f^{-1}(y))=\frac{y-2}{\sqrt{2} } \sqrt{2} -1+3\\\\y=y-2+2\\\\y=y[/tex]

 As LHS = RHS  which means inverse function is correct .

Step-by-step explanation:

I found the graph, the answer should be 25$

The inverse function is given by f⁻¹(x)=∛x+2 and the inverse is a function.

The opposite function is referred to as the inverse of a function. To map the dependent variable y based on the independent variable x, we should ideally utilize a function. The relationship that determines the value of x based on a certain value of y is known as an inverse function.

The domain of a function shifts to the range for an inverse function, and vice versa.

For a function that is mathematically denoted by the formula y=g(x), where g(x) is a polynomial of x. We use y to solve the equation for x.

Given function is in the form  f(x)=(x-2)³

It can be written as

y=(x-2)³

Then we take the cube root on either sides of the equation.

∛y=x-2

or, x=∛y+2

So the inverse function is:

f⁻¹(x)=∛x+2

Answer: Solution is where the x intercepts on the graph

Step-by-step explanation:

The total number of occasions the dice would land on 1 or 3 is 98.

The probability space associated with a randomly chosen experiment is established by three components: the result space, whose element is an experiment outcome, a collection of events F whose elements represent subsets of, and a probability measure IP assigned towards the elements in F.

As a result, for problems like Cards, Coins, and Dices, it is preferable to record the potential scenarios and determine the individual probabilities of each case before ORing/ANDing them in accordance with the problem demand. If done correctly, this will provide a great solution that will never fail you.

All of the probability will add upto 1.

this give us the equation:

P(1)+0.17 + 0.18 + 0.09 + 0.15 + 0.1 = 1

P(1) + 0.69 = 1

P(1) = 1 - 0.69

   P(1)  = 0.31

We now need to find the probability of 1 or 3

P(1 or 3) = P(1) + P(3)

             = 0.31 + 0.18

             = 0.49

We now use the predicting outcomes formula.

expected = P(1 or 3) x no. of times.

                = 0.49 x 200

                = 98

the total number of times the dice will land on 1 or on 3 = 98.

lets start with the first equation

33*33^7

Since they are not in parentheses, the only one going the power of 7 is the second 33. The first 33 will just have n exponent of one, so you add those together and get 33^8

The next equation is explained like this

(33*33)^7

Since this equation is in parentheses, first you will combine the 33:

a. The type of sequence we have here is a Geometric Progression.

b. The common ratio of the sequence is 7/10.

c. iPhone 10 will cost $83 in 2025.

Given sequence is:  

$1000, $700, $490, $343, $240

a. To determine the type of sequence we find the common ratio between terms:

   700/1000 = 7/10

   490/700 = 7/10

All terms differ by a common ratio hence it is a geometric progression.

b. From above,          

 1000 × 7/10 = 700

 700 × 7/10 = 490

 490 × 7/10 = 343

 343 × 7/10 = 240

Hence, the common ratio of G.P is 7/10.

c. The next terms in the given G.P is:

240 × 7/10 = 168

So, iPhone 10 will cost $168 in 2023.

168 × 7/10 = 118

So, iPhone 10 will cost $118 in 2024.

118 × 7/10 = 83

So, iPhone 10 will cost $83 in 2025.

We are Given:

Full amount of fuel = 300 gallons

No amount of fuel = 0 gallons

Thus, the set of all possible input values which is the domain is;

A function is a relation that uniquely associates members of one set with members of another set. More formally, a function from A to B is an object f such that every a in A is uniquely associated with an object f(a) in B. A function is therefore a many-to-one (or sometimes one-to-one) relation. The set A of values at which a function is defined is called its domain, while the set f(A) subset B of values that the function can produce is called its range. Here, the set B is called the codomain off.

A function from a set X to a set Y is an assignment of an element of Y to each element of X. The set X is called the domain of the function and the set Y is called the codomain of the function.

A function, its domain, and its co-domain are declared by the notation f: X→Y, and the value of a function f at an element x of X, denoted by f(x), is called the image of x under f, or the value of f applied to the argument x.

Functions are also called maps or mappings, though some authors make some distinction between "maps" and "functions"

ln 1 is the converted from the expression 2 ln 8-3 ln 4 to a single natural logarithm.

A number's natural logarithm is its logarithm to the base of the transcendental and irrational number e, which is roughly equivalent to 2.718281828459.

Typically, the natural logarithm of x is denoted by the symbols ln x, loge x, or, if the base e is implicit, just log x. When adding parentheses for clarity, the values ln(x), loge(x), or log (x). In order to avoid ambiguity, this is notably done when the argument to the logarithm is not a single symbol.

The power to which e would need to be raised in order to equal x is the natural logarithm of x.

For instance, e2.0149... = 7.5, thus ln 7.5 equals 2.0149.

Since e1 = e, the natural logarithm of e itself, or ln e, is equal to 1, while the natural logarithm of 1 is 0, since e0 = 1.

We need to convert 2 ln 8-3 ln 4 as a single natural logarithm

First apply power property

Answer:

-2

Step-by-step explanation:

For a given atom, net charge can be determined by looking at how many protons the atom has in its nucleus and how many electrons it has surrounding its nucleus.

More specifically, the atom will have

a positive net charge if it has more protons in its nucleus than electrons surrounding its nucleus

a negative net charge if it has more electrons surrounding its nucleus than protons in its nucleus

no net charge if it has equal numbers of protons and electrons

When an atom carries a positive net charge, it forms a cation, or positively charged ion. Likewise, when an atom carries a negative net charge, it forms an anion, or negatively charged ion.

In your case, the atom is said to contain

eight protons

nine neutrons → they do not influence the net charge of the atom

ten electrons

Now, electrons and protons carry opposite charges. A proton is said to carry a 1+ charge, while an electron is said to carry a 1−.

In your case, you have 8 protons and 10 electrons. This means that the atom will carry a total

2×(1−)=2−

net charge.

Therefore, you are dealing with an anion that carries a 2− net charge, i.e. it has two more electrons than it does protons.
