7.5
Step-by-step explanation:
You have two triangles with areas of 1.5 and 3 as well as a rectangle with an area of 3
The key to your answer is in d): What is a success? What is a failure?
If a patient was -6.0 diopters and after Lasik was -1.00 diopter, most surgeons and those in the industry would consider this a failure. The patient, however, may consider it a success because at age 50 she does not need to use reading glasses and still qualifies for a driver's license with 20/40 distance vision.. A patient who can make out the Snellen 20/20 line - familiar letters in black on a white background in a controlled lighting environment - may be considered by the doctor a success, but the patient does not have the crispness of vision experienced before Lasik and with glasses.
The nonprofit patient advocacy USAEyes.org took a different approach. Success of Lasik means that the patient received what was expected - no matter the numbers. Using a scale of Much Worse Than Expected, Worse Than Expected, As Expected, Better Than Expected, and Much Better Than Expected, the USAEyes Competence Opinion Reletave to Expectations (CORE) patient survey found:
99% report quality of life as expected, better, or much better 98% day vision as expected, better, or much better 98% no complications or issues are seldom problematic 98% would recommend surgery to family and friends. 97% would have surgery again, knowing what they know now 96% wear corrective lenses as often as expected, less, or much less than expected 96% report postop vision without lenses as expected, better, or much better than expected when compared to preop vision with lenses 96% report overall quality of vision as expected, better, or much better than expected 91% no complications at any time 91% night vision as expected, better, or much better 7% complications seldom problematic – yet 91% of these same patients would have surgery again 2% complications frequent or always problematic – yet 22% of f these same patients would have surgery again
Answer:
I don't see how the three existing points could ever become a square with the addition of a foiurth point.
Step-by-step explanation:
See the attached image.
A square would require that all angles be 90 degrees. The given points are the top three points on the graph. If we enter the two equations that intersect these points (blue and black lines), we can see that the angle on top is not 90 degrees. I can't see that this could ever be a square with a fourth point, z. I did find a value for z that make the four points a parallelogram.
The answer is : y = -3x + 1
