What statement is true about the sum of two rational numbers

After evaluating the logarithm log₂ 2⁵, we get the result as 5.

The common logarithm is also known as the base 10 logarithm. It is represented by log10 or simply log.

For example, the common logarithm of 1000 is written as log(1000). The common logarithm defines how many times we need to multiply by 10 to get the required output.  The natural logarithm is called the logarithm of base e. The natural logarithm is represented by ln or loge. Here, "e" stands for Euler's constant which is approximately equal to 2.71828.

For example, the natural logarithm of 78 is written as ln 78. The natural logarithm determines how much we need to multiply "e" to get the required output.

We need to evaluate log₂ 2⁵Using the property logₐ (mⁿ) = n logₐ m log₂ 2⁵ can be written as

log₂ 2⁵ = 5 log₂ 2

We know that logₐ a = 15 log₂ 2= 5

Therefore, after evaluating the logarithm log₂ 2⁵, we get the result as 5.

To calculate the value of the function f(x) + 1, we use the following definitions:

New function = f(x) + 1

Substitute f(x) = 3x + 2 in New function = f(x) + 1

So, we have

New function = 3x + 2 + 1

The result of simplifying each number 64²/₃ 64²/₃  using the exponent rules is 256

To solve this exercise we have to resolve algebraic operations following the exponent rules.

64²/₃ * 64²/₃

The base number 64 is the same that: 4³, then we get:

Answer:

see explanation

Step-by-step explanation:

substitute the values of x, situated inside the parenthesis into f(x)

f(- 1) = - 1 - 5 = - 6

f(0) = 0 - 5 = - 5

f(1) = 1 - 5 = - 4

f(2) = 2 - 5 = - 3

f(5) = 5 - 5 = 0

f(8) = 8 - 5 = 3

1) Substitute x = -1 into f(x) = x - 5

2) Substitute x = 0 into f(x) = x - 5

3) Substitute x = 1 into f(x) = x - 5

4) Substitute x = 2 into f(x) = x - 5

5) Substitute x = 5 into f(x) = x - 5

6) Substitute x = 8 into f(x) = x - 5

The solution for the given logarithmic expression log₂4+3 log₂9 as a single logarithm is log₂ (2916).

A logarithmic equation is one that includes a logarithm in the variable x.

An exponential formula is one where the variable is represented by an exponent. To answer exponential equations, first determine whether both sides of the equation can be written as powers of the exact number. If you can't, take the common logarithm from both of the equation's sides and use property 7 to solve the problem.

Now, as per the stated condition in question;

The expressed equation is;

= log₂4+3 log₂9

Using the Power Rule in the second term.

= log₂4+log₂9³

=  log₂4+log₂729

As, the base of each log term is 2. We can use product rule to simplify the equation.

= log₂(4×729)

= log₂ (2916) [As a single log function]

Therefore, the simplification of the given logarithmic expression as the single logarithm is log₂ (2916).

The two pages the boys are reading are pages 31, and 30. I'm not sure which is which. (would depend on who is reading the odd number page).

Josiah is reading page 31. The page he is reading is an odd-numbered page is 31 by factorizing number.

Step 1: Determine the factors of 930.

The factors of 930 are 1, 2, 3, 5, 6, 10, 15, 31, 62, 93, 155, 186, 310, 465, and 930.

Step 2: Identify the factors that correspond to odd-numbered pages in the book.

Since Josiah is reading an odd-numbered page,  eliminate the even factors.

This leaves  with the odd factors:

1, 3, 5, 15, 31, 93, 155, and 465.

Step 3: Determine which odd factor corresponds to a page number within the range of the book.

Since the book has 50 pages,  eliminate the odd factors greater than 50. This leaves us with the odd factors: 1, 3, 5, 15, and 31.

Step 4: Identify the odd factor that, when multiplied by its complement, equals 930, that is:

31 × 30 = 930,

so Josiah is reading page 31.

Therefore, Josiah is reading page 31 of the book.

Step-by-step explanation:

Step-by-step explanation:

The situation in which a function behaves differently over different parts of its domain is modeled by considering it to be a piecewise function.

What is Mathematical function ?

Function is defined as the expression or relation between any given two variables such as x and y and there must be an independent variable and dependent variable

Such a situation can be explained through an example:

f(x) =   { x, for x > 0

        {     1, for x = 0

        { -x, for x < 0

now, when we take x value less than 0, say x= -1

   thus, f(x)= f(-1)= -(-1) = 1 , here we used f(x) given x<0

now, when we take x value more than 0, say x= 1

   thus, f(x)= f(1)= (1) = 1, here we used f(x) given x>0

now, when we take x =  0,

   thus, f(x)= f(0)= 1, here we used f(x) given x=0

this is how we model piecewise function, we  use f(x) as per the value of x. Following image shows plotted answer for this example.

Since inequalities given are exclusive of 0, we leave the dot at the origin unfilled. Now, for x = 0. Since the value is constant at f(x) =1, we pointed a point at (0,1)

Raising both sides by 10, in order to remove the logarithm:
