A function is defined by f(x) = (x + 2)/x, where x * 0. Find f-¹(x)
The value of f-¹(x) for the function f(x) = (x + 2)/x is y = 2/(x-1).
The inverse of a function f is denoted by f-¹ and it exists only when f is both one-one and onto function. An inverse function in mathematics is function which "reverses" the another function.
For example, If function f which is applied to input a gives result b and then applying inverse of the function g to b, it gives result a and vice versa.
It can be written as:
f(a) = b if and only if g(b) = a or, f⁻¹ (b) = a
In order to calculate the inverse of function f(x) = (x + 2)/x just simply swap the x and y, and solve the resulting equation for the x.
So, we have f(x) = (x + 2)/x, swap the variable x by y, we get
f(x) = (y + 2)/y ............(1)
Now, solving the above equation x = y+2/y for y.
⇒y = 2/(x-1)
∴ The value of f-¹(x) for the function f(x) = (x + 2)/x is y = 2/(x-1).

How many Arithmetic means must be inserted between 1 and 36 so that the
sum of the resulting arithmetic progression shall be 148 ?
The Arithmetic means will be inserted between 1 and 36 such that the
sum of the resultant arithmetic progression will be 148 is 8.
What is defined as arithmetic progression?The distinction between the 2 arithmetic orders is a constant value in Arithmetic Progression (AP). Another name for it is Arithmetic Sequence.
We'd arrive along all a few key words in AP, which were denoted as:
The first term (a)Common difference (d)Term nth (an)The total of first n terms (Sn)The AP can also be defined in terms of common distinctions, as illustrated below.
The method of calculating an AP's n-th term is as follows: an = a + (n − 1) × dThe following is the arithmetic progression sum: Sn = n/2[2a + (n − 1) × d].Common difference 'd' of an AP: d = a2 - a1 = a3 - a2 = a4 - a3 = ...... = an - an-1.Now, for the stated question;
Assume the first term is'a₁' = 1.
The last term of the series that is nth term is 'a₃₆'.
The sum of all digits between 1 and 36 is given as 148.
Thus, Sn = 148
Substitute the value in the sum formula.
Sn = (n/2)×(a₁ + a₃₆)
148 = (n/2)×(1 + 36)
148 = (n/2)×(37)
n = (148×2)/37
n = 8.
Thus, the total number of Arithmetic means that can be inserted between 1 and 36 is 8.

Find the measure of the arc or angle indicated.
Applying the inscribed angle theorem, we have:
1. Measure of inscribed angle EDF = 53°
2. m<DCB = 92°
3. m<VWS = 37°
How to Apply the Inscribed Angle Theorem?In a circle, the measure of an inscribed angle is equal to half of the measure of the measure of the intercepted arc, based on the inscribed angle theorem. In order words, the measure of the intercepted arc in a circle, is always twice the measure of the inscribed angle in the circle.
1. Measure of intercepted arc EF = 106° [given]
Measure of inscribed angle EDF = 1/2(measure of arc EF) [inscribed angle theorem]
Substitute
Measure of inscribed angle EDF = 1/2(106)
Measure of inscribed angle EDF = 53°
2. m<DCB + m<DQB = 180° [opposite angles of a cyclic quadrilateral add up to 180 degrees]
Substitute
m<DCB + 88 = 180
m<DCB + 88 - 88 = 180 - 88
m<DCB = 92°
3. m<VWS = 1/2(measure of arc VS) [inscribed angle theorem]
Substitute
m<VWS = 1/2(74)
m<VWS = 37°

What is the coefficient with x in that form?
Step-by-step explanation:

Coefficient of x is 3
It is usually an integer that is multiplied by the variable and written next to it. The variables which do not have a number with them are assumed to be having 1 as their coefficient. For example, in the expression 3x, 3 is the coefficient of x but in the expression x2 + 3, 1 is the coefficient of x2.

Inventory accounting can often be used for unethical or fraudulent behavior. Discuss the accounting principles and practices as they relate to inventory, and list one or more way(s) that fraudulent activity can take place
One way to reduce the risk of fraudulent activity is to assign two persons to check the inventory.
Accounting principles lay out the basic guidelines and ideas and create the foundation upon which specific accounting standards are built.
Inventory-related accounting principles and procedures might be applied unethically. For instance, many teachers in my field who are required to gather and check-in inventory do so while keeping the inventory for themselves. Having two persons check off the inventory is one method to lower the risk.
Accounting fraud is the illegal modification of a company's financial statements in an effort to hide earnings or losses or to manipulate the company's appearance of health. Accounting fraud can be committed in a variety of ways, including overstating revenue, failing to record expenses, and misrepresenting assets and liabilities.

I have a height of a shadow that is 523 in the height of myself and my shadow 64 in and 180 in i need to cross multiply to find out what the height of the tree is
The height of the tree is 186 inches if Shadow of tree is 523 inch shadow of human is 180 inch height of human is 64 inch.
What is cross multiplication?Cross multiplication occurs when the numerator of the first fraction is multiplied by the denominator of the second fraction, and the numerator of the second fraction is multiplied by the denominator of the first fraction.
We have given information that
Shadow of tree = 523 inch
Shadow of human = 180 inch
Height of human = 64 inch
height of tree = x
Lets solve this with cross multiplication
⇒ [tex]\frac{64}{180} = \frac{x}{523}[/tex]
⇒ 180 × x = 64 × 523
⇒ x = (64 × 523)/180
⇒ x = 185.95

We need to know about radical form of a number to solve the question. The simplified version of 2[tex]\sqrt{243}[/tex]x is 18[tex]\sqrt{3}[/tex]x.
Radical form of a number is the simplified version of the number where there is no square root or third root or fourth left of the number.If there is a square root of a number present then we have to simplify it and break it down to a square root from where no other natural number root can be found.In this question we have a number 2[tex]\sqrt{243}[/tex]x, we have to simplify [tex]\sqrt{243}[/tex] so we get the radical form of the number and we assume that x>=0. We can write 243 as 9x9x3, so we can see that for the square root of 243 we can write 9[tex]\sqrt{3}[/tex]. So the number 2[tex]\sqrt{243}[/tex]x can be written as 2x9[tex]\sqrt{3}[/tex]x=18[tex]\sqrt{3}[/tex]x.
Therefore we got the radical form of 2[tex]\sqrt{243}[/tex]x to be 18[tex]\sqrt{3}[/tex]x.

A jar contains 100 marbles. There are 21 blue marbles, 19 green marbles, 37 red marbles, and 23 yellow marbles. What is the probability of randomly selecting a yellow marble? Enter the correct answer
The probability of getting yellow marbles is 0.23.
What is probability?Probability is the measure of the likelihood that an event will occur in a Random Experiment.
Experiment: A trial or an operation conducted to produce an outcome is called an experiment.
Sample Space: All the possible outcomes of an experiment together constitute a sample space. For example, the sample space of tossing a coin is head and tail.
Favorable Outcome: An event that has produced the desired result or expected event is called a favorable outcome. For example, when we roll two dice, the possible/favorable outcomes of getting the sum of numbers on the two dice as 4 are (1,3), (2,2), and (3,1).
Trial: A trial denotes doing a random experiment.
Given:
Total marbles= 100
blue marbles = 21
green marbles= 19
red marbles = 37
yellow marbles= 23
So, the probability of randomly selecting a yellow marble
= 23/100
= 0.23
