10. The Vertical Motion Model states that the quadratic function h(t) = -167' + 38t + 5 models the path of a rocket propelled into the air from a launch pad 5 feet off the ground. Use this model to answer the following questions:
a. How long does it take for the rocket to reach its maximum height?
b. What is the rocket's maximum height?
C. How long does it take for the rocket to land back on earth?

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.

step-by-step explanation:

i believe its "c" because all of the other options include a but it could be d because there is a way of financing with cash at certain places but its uncommon.
