ryaan goes skydiving and falls at a constant rate toward the ground. the equation y = -32x + 14,000 represents the situation where y is the height of ryaan in feet above the ground and x is the seconds since she jumped.

which statement describes the situation?

a. from a starting position of 14,000 feet above the ground, she is ascending at 32 feet per second.

b. from a starting position of 32 feet above the ground, she is ascending at 14,000 feet per second.

c. from a starting position of 14,000 feet above the ground, she is descending at 32 feet per second.

d. from a starting position of 32 feet above the ground, she is descending at 14,000 feet per second.

mutiple choice ! 1

C, because

-32 x seconds since she jumped + 14000

because 14000 would be 14000 units above 0, and -32 represents the seconds she had jumped, which would basically be -32+14000, which is the same as saying 14000 - 32.

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.
