Use the Change of Base Formula to evaluate each expression.
log₃33

Answers

Using the change of base formula the evaluated value of [tex]log_{3} 33[/tex]  is 3.184

Change of base formula is used to change the base of logarithm. It is used to write a logarithm of a number with a given base as the ratio of two logarithms each with the same base that is different from the base of the original logarithm.

According to the change of base formula :

[tex]log_{a} b = \frac{log_{x} b}{log_{x} a}[/tex]      

where base x is base 10

According to the question, we have to find the value of [tex]log_{3} 33[/tex]

Thus applying change of base formula we get

  [tex]log_{3} 33 = \frac{log_{10} 33}{log_{10} 3}[/tex]

calculating the value of log from the calculator we get,

    [tex]log_{3} 33 = \frac{1.519}{0.477}\\log_{3} 33 = 3.184[/tex]  

Thus using the change of base formula the evaluated value of [tex]log_{3} 33[/tex] is 3.184

1/6y+3/8x=24 rate of change

Answers

The constant average rates of change of 1/6y + 3/8x = 24 is -9/4

What are linear equations?

Linear equations are equations that have constant average rates of change.

Note that the constant average rates of change can also be regarded as the slope or the gradient

How to determine the constant average rates of change?

The linear equation is given as

1/6y + 3/8x = 24

Multiply through the equation 1/6y+3/8x=24 by 24 to eliminate the fraction

So, we have

24 * 1/6y + 24 * 3/8x = 24 * 24

Evaluate the product

So, we have

4y + 9x = 576

Rewrite the equation as

So, we have

4y = - 9x + 576

Divide through the equation by 4

So, we have

y = - 9/4x + 144

A linear equation is represented as

y = mx + c

Where

m = rate of change

So, we have

m = -9/4

Hence, the constant average rates of change of 1/6y + 3/8x = 24 is -9/4

Determine whether each logarithm is a common logarithm.
b. (log 64)

Answers

The logarithm function ( log 64 ) is not a common logarithm function as it does not have a base 10 but ahs a base e.

In mathematics, the common logarithm is the logarithm with base 10.

It is also known as the decadic logarithm and as the decimal logarithm function.

Here, we have the logarithm function as:

( log 64 )

Now, we can see that:

It does not have a base.

So, we will take the base as e.

So, it will not be a common logarithm function as having base 10 is an important characteristic of a common logarithm function.

Therefore, we get that, the logarithm function ( log 64 ) is not a common logarithm function as it does not have a base 10.

Two men shared the cost of a business in the ratio 2:3. if the smaller share is 75000, find the total cost of the business?

Answers

The total cost of business is 1,87,500

We are given the ratio of shares of two men. So, let the share of first person be 2x and share of second person be 3x.

It is also stated that smaller share is 75000. Out of the two shares, 2x is the smaller one. So, relating the two statements -

2x = 75000

x = 75000 ÷ 2

Performing division

x = 37500

So, finding the larger share now -

Larger share = 3x

Larger share = 3×37500

Performing multiplication

Larger share = 112500

Total cost of business = Smaller share + Larger share

Total cost of business = 75000 + 112500

Total cost of business = 1,87,500

Hence, the total cost of business is 1,87,500.

25% in the decimal number system is 0.25.

What are decimal numbers?The base-10 number system, arguably the most widely used number system, is referred to as decimal. The ten single-digit numbers in the decimal number system are 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9. The number following nine is 10. 19 is followed by 20, and so on.Decimal fractions and recurring (repeating or non-terminating, like) decimals are the three different types of decimals (a.k.a. converting a decimal into a fraction whose denominator is a power of ten).

So, we need to divide the number by 100 and we want to convert a number in percentage into decimals.

Then,

25/100 = 0.25

According to the question,

given that,

Sue's water bottle holds the water = [tex]\frac{1}{2}x + \frac{1}{2}x[/tex] = [tex]\frac{2}{2}x[/tex] = x

In its simplest form in algebra, the definition of an equation is a mathematical statement that shows that two mathematical expressions are equal. For instance, 3x + 5 = 14 is an equation, in which 3x + 5 and 14 are two expressions separated by an ‘equal’ sign. The most basic and simple algebraic equations consist of one or more variables in math.

Different Types of Equations:

Some of the math equations used in algebra are:

Linear Equation

A linear equation may have more than one variable. A linear equation is an equation in which the highest power of the variable is always 1. It is also known as a one-degree equation.

Quadratic Equation

This is a second-order equation. In quadratic equations, at least one of the variables should be raised to exponent 2.

Example:

[tex]a x^{2}[/tex] + b x + c = 0

Cubic Equation

This is a third-order equation. In cubic equations, at least one of the variables should be raised to exponent 3.

Example:

[tex]a x^{3}[/tex] + [tex]b x^{2}[/tex]+ cx + d = 0

[tex]a^{3}[/tex] – 27 = 0

Rational Equation

A rational equation is an equation that contains fractions with a variable in the numerator, denominator, or both.

Example:  

[tex]\frac{x}{2}[/tex] = [tex]\frac{x + c}{4}[/tex]

How to prove an equation

One way to prove that an equation is true is to start with one side (say, the left-hand side) and to convert it, by a sequence of equality-preserving transformations, into the other side. But remember that a proof must be easy to check, so each step deserves a justification. We keep the steps elementary, based on known facts of algebra. Also, a proof should always start with a statement of the claim that is being proved.

Decimal Fraction Math refers to the mathematical expression of a fraction or mixed number where the denominator is a power of 10, such as 10, 100, or 1000, etc. Mathematical operations can be performed on fractions more easily when they are expressed in decimal form.

From 0 to 9, single-digit numerals are read exactly as they are written. However, when two numerals are involved, the left digit implies 10 times what the right digit indicates. In the number 24, that is, 4 is 4 and 2 is 20. Together, they make 24.

The rightmost digit of a three-digit number has the same meaning as the middle one, which is ten times the digit, and the leftmost digit, which is 100 times the digit.

√97.5 + 1.96

=  9.874 + 1.96

find the distance between B and H

Answers

The distance between the points B and H on the coordinate plane is 4.48 units

What is the distance between the points B and H?

See below for the complete question

The coordinates of the points B and H are given as:

(-2.63, 7) and (1.85,7)

Rewrite properly as

B = (-2.63, 7)

H = (1.85,7)

The distance between any two points on a coordinate plane is calculated using the following distance formula

d = √(x2 - x1)^2 + (y2 -y1)^2

Substitute the known values in the above distance equation

So, we have

d = √(-2.63 - 1.85)^2 + (7 - 7)^2

Evaluate the exponents

So, we have

d = √20.0704 + 0

Evaluate the sum

So, we have

d = √20.0704

Evaluate the exponent

So, we have

d = 4.48

Hence, the distance between the points B and H on the coordinate plane is 4.48 units
