cervical cancer is increasing in the US. The study of epidemiology focuses on the interventions and preventions available to decrease the prevalence and incidence of HPV‚ cervical cancer‚ and genital warts in teenagers. This paper will evaluate the role of epidemiology in HPV by utilizing the epidemiological triangle‚ methods and types of epidemiology‚ the population affected‚ and the levels of prevention in the HPV disease. “Epidemiology is the study of populations in order to: monitor the

value is held constant. r as a Constant If we let the value of r be equal to 1‚ we can use that information to find the length of OP’ when OP=2‚ 3‚ and 4. The first thing one can deduce is that by using the points A‚ O‚ P’‚ and P two isosceles triangles can be formed; ∆AOP and ∆AOP’. To rationalize this assertion through an analytic approach it should first be understood that all line segments that connect the center of a circle to its perimeter‚ or circumference‚ is considered to be its radius

The life and brutal death of Hypatia of Alexandria has been a topic of debatable discussion since the 4th century C.E. She lived Alexandria‚ Egypt (the center of ancient knowledge) and while it is assumed that she learned the study of mathematics from her father‚ “Theon of Alexandria” it is known that she was the head geometry teacher of the Neo-Platonist school (Belenky‚ 2010). Hypatia is regarded as one of the first women that contributed in many ways to the field of mathematical findings that
