Given the vertex of a parabola is (-6, 8) and its focus is (-6, 10), find the equation.

Step-by-step explanation:

If you plot the vertex and the focus, you'll see that the focus is 2 units above the vertex. That tells us 2 things: first, that the parabola opens upwards and, second, that the value of p in our equation is 2 (since p is the number of units between the vertex and the focus). The equation is:

where h and k are the coordinates of the vertex and p is the number of units between the vertex and the focus. The vertex is given as (-6, 8), so h is -6 and k is 8. p is 2, so filling in we get:

which simplifies down to

Not sure in what form you need it, so I'll leave it like that and you may have to do some algebraic manipulation to get it into the form your teacher wants it in.

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.
