Find three different ways to write the number 437,000 using powers of 10.

4370*10^2

437*10^3

43.7*10^4

Step-by-step explanation:

The given number is

437000

Scientific notation can be used to write the number in different ways. We can use the powers of 10 to write the given number.

First way:

The first way is:

4370*10^2

Separating the hundred from the given number

The second way:

437*10^3

Separating the 1000 from the number in the form of power of 10

The third way:

43.7*10^4

Hence scientific notation can be used for writing the number in different ways..

introduction, methodology, results, discussion

step-by-step explanation:

an observational study is one which consists of actual observation to record data and then analyse the data.

there are a number of factors that should be analyzed before starting an observational study.

the main four factors are:

i) introduction:   this should be analysed to check whether the purpose of the study is correctly established and the data recorded are appropriate for the study

methodology:   the method of collecting the data, such as whether randomly selected, and whether sample size matches with the population to be studied, whether questions asked are easy to answer by common men, etc.

results: then results such as summary of data with comments should be studied thoroughly

discussion:   the last is the discussion, this can be either by management people or persons who are all interested , etc.

answer

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,
