The sales of lawn mowers t years after a particular model is introduced is given by the function y = 5500 ln (9t + 4), where y is the number of mowers sold. how many mowers will be sold 4.5 years after a model is introduced?

44.5

Step-by-step explanation:

First know that the y=5500 is just there to confuse you. Focus on the other equation that was given to you: 9t+4. with "t" meaning years you have to plug it in- or substitute the "t" variable for 4.5 because the variable means years and 4.5 years are given- and multiply to get 40.5. Then u add 40.5 to 4 and get 44.5 as your final answer.

1) 9(4.5) + 4

2) 40.5 + 4

3) 44.5

If I'm wrong then here's a possible alternative: add 44.5 to 5500.

what is the starting amount? the question is not clear sorry.

step-by-step explanation:

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.
