Layla tried to define a rotation. For the center point C, the image C' is at the same point as C.
For a point P that is not at C, a counterclockwise rotation of 0 about point C creates point P'
P, prime, such that m\angle PCP'=m∠PCP =θm
What mistake did Layla make in her definition of a rotation?
Choose 1

(Choice A)
A
Layla needed to include the distance between each point PPP and its image P'P
′
P, prime.

(Choice B)
B
CPCPC, P must be perpendicular to CP'CP
′
C, P, prime.

(Choice C)
C
The lengths of \overline{CP}
CP
start overline, C, P, end overline and \overline{CP'}
CP
′

start overline, C, P, prime, end overline must be equal.

(Choice D, Checked)
D
Layla did not make a mistake.

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.

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11
