Is 4 a real number?.

The word "logarithm" is derived from the Greek meanings for "ratio" (logos) and "number" (arithmos).

In the 17th century, Scottish mathematician John Napier (1550-1617) developed logarithms as a tool for computing. He derived the phrase from the Greek words for ratio (logos) and number (arithmos).

Before mechanical (and later electronic) computers were developed, logarithms were essential for simplifying calculations in astronomy, navigation, surveying, and afterwards engineering. A logarithm is a mathematical formula that calculates how many times the base, or initial number, must be multiplied by itself to produce the target number. As a result of the relationship between logarithms and geometric progressions.

The total price including tax, Fawaz has to pay is $36 round to the nearest cent.

To find the total price of the phone including tax, we need to add the tax amount to the price of the phone. The tax rate is 9%, which means that for every $1 of the price of the phone, $0.09 will be added as tax. To find the total price including tax, we can use the following formula:

Total price = Price of the phone + (Price of the phone x Tax rate)

Given the information in the problem, we know that:

Price of the phone = $33

Tax rate = 9% (expressed as a decimal)

Plugging these values into the formula, we get following equation:

Total price = $33 + ($33 x 0.09)

To solve for total price, we need to calculate ($33 x 0.09)

= $3

Total price = $33 + $3

Total price = $36

So the total price including tax, Fawaz has to pay is $36 round to the nearest cent.

In simple words, we have multiplied the price of the phone with the tax rate and then added the tax amount with the price of the phone to get the total price including tax.

Note: The tax rate is given as 9% which is equal to 0.09 in decimal form.

Therefore, The total price including tax, Fawaz has to pay is $36 round to the nearest cent.

The integers of a coordinate grid are used to find points. Each point on a graph may be specified by an ordered pair of numbers called an x-coordinate and a y-coordinate, respectively.

An ordered list's pairings are indicated by parentheses (x, y) (x,y). beginning place is at (0,0). Remember that when writing coordinates, there is usually no space after the comma. The co-ordinates in graphs are the cartesian coordinate points which enables us to exactly trace the specific point on a graph. There are 4 quadrants in a graph namely first second 3rd and 4th. When we have data about X&Y coordinate of each point those points can be traced on the graph on their respective axis. For example, x,y is equal to 2, 5 lies on the first quadrant since both the values are positive.

Equivalent sets must have the same cardinality, i.e., n(A) = n(B) where, n(A ) and n(B) are the number of elements in set A and set B respectively.

Equivalent Sets means that there should be a one-to-one correspondence between the elements of both sets. Equal sets and equivalent sets are two different concepts. A is equivalent to B if A and B are two sets such that n(A) = n(B). This means that two equal sets are always equal, but the opposite of the same may or may not be true.

Statement: Set A and Set B are equivalent.

Proof: Let us consider two sets A and B. Let 'a' be any member of A. We need to show that "a" is also a member of B. Then let "b" be any member of B. We must show that b is also a member of A. If the members of A and B are defined by an algorithm or set of features, it must be shown that algorithms that define elements of A also define elements of B, and vice versa.

The answer is:

The given parameters are:

Start = 24 inches

Rate = 6 inches/second

The function model of the height is determined using a linear function:

h(t) = Start + Rate × t

Where: t represents the time in seconds

So, we have:

h(t) = 24 + 6 × t

This gives

h(t) = 24 + 6t

After 22 seconds, the height of the periscope will be

h(22) = 24 + 6 × 22

h(22) = 24 + 132

A right angle does not always have two equal sides, only in the case of an isosceles triangle it will have two equal sides.

A triangle is said to have a right angle if one of the angles is 90 degrees. Right triangles are those having angles at 90 degrees, which are referred to as right angles.

The Pythagorean rule may be used to understand the relationship between the different sides of this triangle. The biggest side, also known as the hypotenuse, is the side that forms the right angle.

The right triangles are further divided into isosceles and scalene right triangles based on the other angle values.

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

Here,
Let 'a' be the cost per gallon of fuel in the year 2000, and 'b' be the inflation rate per year. If the rate of inflation is constant then
After 7 year inflation = 7b
Cost of fuel in 2007 = a + 7b

according to the question
Change in cost of fuel
= cost in 2007 - cost in 2000

The formula of the nth term in the arithmetic sequence is a(n) = 3 + (n-1)9.

An arithmetic sequence is a sequence of numbers in which each term after the first is obtained by adding a fixed constant, called the common difference, to the preceding term.

The sequence can be represented by the general term an = a1 + (n-1)d, where a1 is the first term and d is the common difference

In an arithmetic sequence, the difference between consecutive terms is constant. Therefore, if a(1) = 3 and a(2) = 12, the common difference (d) is 12 - 3 = 9.

The nth term of an arithmetic sequence is given by the formula:

a(n) = a(1) + (n-1)d

where:

a(n) is the nth term of the sequence

a(1) is the first term of the sequence

d is the common difference

n is the position of the term in the sequence

So, for the given sequence, the nth term a(n) of the arithmetic sequence is:

a(n) = a(1) + (n-1)d = 3 + (n-1)9

This means that the nth term of the arithmetic sequence is found by adding the common difference (9) to the first term (3), and then multiplying the result by (n-1) which indicates the position of the term in the sequence.

Therefore, a(n) = 3 + (n-1)9 is the formula of the nth term in the arithmetic sequence.
