Find the inverse of each function. Is the inverse a function? f(x)=1/4x
The Inverse of given function F(x) = 1 / 4x is F⁻¹(x) = 1 / 4 x
F(x) = 1 / 4x is a function of x.
Changing F(x) to the variable y
This means that F(x) = 1/4x becomes y = 1/4x.
Changing the variables x and y in the previously obtained equation
This means that we can deduce x = 1 / 4y from the equation y = 1 / 4x.
Solving the newly discovered equation for y
This means that we must simplify the equation by rearranging the terms in order to obtain the equation in terms of the variable x.
x = 1 / 4y
=> 4 y = 1 / x
=> y = 1 / 4 x
As a result, we obtain the required equation.
Switching the variable y with F⁻¹(x)
This assumes, y = 1 / 4 x becomes F⁻¹(x) = 1 / 4 x
Hence, the value of the given function F⁻¹(x) = 1 / 4 x

Write each equation in exponential form.
log₄1=0
Answer:
The answer to the given equation is 1
Logarithmic scale: A measurement scale in which the position is marked using the logarithm of a value rather than the actual value.
A logarithmic equation includes a logarithm in the variable x.
An exponential equation is one in which the variable is represented by an exponent. A logarithmic equation is one in which the logarithm of a variable-containing expression is used.
For logarithmic equations, log b (x) = y is equivalent to b^y = x such that x > 0, b > 0 and b is not equal to 1.
In the given problem b = 4, x = 1 and y = 0
b = 4
x = 1
y = 0
Substituting the values of b, x and y into the equation b^y = x;
4^(0) = 1

addie organizes the Venn diagram below showing the factors of 56 and 42. Reid says that she is incorrect. Who is corect? justify your thinking
Addie is correct because both 2 and 14 are common factors of 56 and 42.
Who is correct?The factor of a number is the number that can perfectly divide another number without leaving any remainder. For example, a factor of 20 is 10 because 10 perfectly divides 20 to 2.
A common factor is a factor that is common to two or more integers. An example of a common factor of 15 and 20 is 5.
A Venn diagram uses circles that overlap each other to show logical relationships between two or more sets of items. The numbers at the intersection of the two circles are common to both numbers.
Factors of 56 = 1, 2, 4, 7, 8, 14, 28 and 56.
Factors of 42 = 1, 2, 3, 6, 7, 14, 21 and 42.
Common factors = 1, 2, 7, 14
This means that Addie is correct because both 2 and 7 are common factors of 56 and 42.

The table gives the average number of days of rain in each month of the year. Find the median of the
given data.
The median of a data set is 9.5
How to find mean and median of a data?Mean is the ratio of sum of the observations to the total number of observations.
Median is such a number for the arranged data set(ascending or descending order) such that to its left and to its right belong same number of observations.
The median of a data set is the middle number when all of the data points are ordered from smallest to largest. For the data set, the first thing you want to do is put them in order from smallest to largest gives you:
6 6 7 7 7 9 10 10 10 10 11 12
Then we will find the middle of the data set. Since there is an even number of twelve data points; it will be between the sixth and seventh point:
6 6 7 7 7 9 ^ 10 10 10 10 11 12
Now the average of those two in the middle to get the median:

Write each equation in logarithmic form.
10³=1000
We get the equation in logarithmic form as log₁₀ 1000 = 3.
A “logarithmic equation” is an equation which involves the “logarithm” of any expression which is containing a variable.
Now, we have been given an equation:
10 ³ = 1000
We need to write it in the logarithm form.
We know that, it will be written as:
log₁₀ 1000 = 3
Since the power goes after the equal sign, so 3 is placed after the equal sign.
The actual value is taken after log, so 1000 is placed there and the base number is taken as the base for the log, so 10 is taken as the base for the log.
Therefore, we get the equation in logarithmic form as log₁₀ 1000 = 3.

In most of the previous examples there were only two terms. Extend your work with using the distributive
property "backwards" and write the following as a product of binomials.
(a) x(x+2)+3(x+2)+4x(x+2)
(b) 2x(x-5)+3(x-5)+(x-1)(x-5)
The expression is written as a product of binomials as;
a) (x + 2) (5x + 3)
b) (x - 5) ( 3x + 2)
What is Distributive property?
Distributive property is said to be multiplying the sum of two or more number will give the same result as multiplying each addend individually by the number and then adding the products together.
Now, For solving the expression by using the distributive property "backwards" , we can find the GCD of each term using in the expression as;
(a) x(x+2) + 3(x+2) + 4x(x+2)
GCD of x(x + 2), 3(x + 2), 4x(x + 2) = (x + 2)
Hence, Firstly take (x + 2) as common term we get;
x (x + 2) + 3(x + 2)+ 4x(x + 2) = (x +2) ( x + 3 + 4x)
= (x + 2) (5x + 3)
The expression is written as a product of binomials as;
a) x (x + 2) + 3(x + 2)+ 4x(x + 2) = (x + 2) (5x + 3)
And, (b) 2x(x-5) + 3(x-5) + (x-1) (x-5)
GCD of 2x(x-5) , 3(x-5) , (x-1) (x-5) = (x - 5)
Hence, Firstly take (x - 5) as common term we get;
2x(x-5) + 3(x-5) + (x-1) (x-5) = (x - 5) (2x + 3 + x - 1)
= (x - 5) ( 3x + 2)
So, The expression is written as a product of binomials as;
b) 2x(x-5) + 3(x-5) + (x-1) (x-5) = (x - 5) ( 3x + 2)
Therefore, The expression is written as a product of binomials as;
a) (x + 2) (5x + 3)
b) (x - 5) ( 3x + 2)
