Which statements justify that the dilation of triangle stu is an enlargement increasing its size by the magnitude of the scale factor? check all that apply. the triangle pre-image is closer to the point of dilation than the image. the triangle image is closer to the point of dilation than the pre-image. the value of the scale factor, , is between 0 and 1. the value of the scale factor, 6, is greater than 1. the vertices of the pre-image are collinear with the vertices of the image.

Answer from: tmax267

Scale factor is the ratio of the distance of centre of dilation to the image divided by that to the preimage. therefore:
a dilation is a magnification if the scale factor is greater than one.
it is a shrinking if the scale factor is less than one.
if the scale factor is exactly one, then the image coincides with the preimage.

the triangle pre-image is closer to the point of dilation than the image.
[so the image distance is farther than the preimage => image is bigger, so magnification]
the triangle image is closer to the point of dilation than the pre-image.
[ image is closer to point of dilation, so smaller => shrinking ]
the value of the scale factor, , is between 0 and 1.
[ scale factor < 1 => shrinking ]
the value of the scale factor, 6, is greater than 1.
[ scale factor > 1 => magnification ]
the vertices of the pre-image are collinear with the vertices of the image.
[ the line of collinearity is not defined, so statement is meaningless. ]

Answer from: Quest

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.
