p =0.007y^(2)-0.02y+118 if a persons systolic pressure is 130.67 mm hg, what is their age?

Typically, when a person coughs, he or she first inhales about 2.50 L of air at 1.00 atm and 25 ∘C. The epiglottis and the vocal cords then shut, trapping the air in the lungs, where it is warmed to 37 ∘C and compressed to a volume of about 1.70 L by the action of the diaphragm and chest muscles. The sudden opening of the epiglottis and vocal cords releases this air explosively. Just prior to this release, what is the approximate pressure of the gas inside the lungs?

You use a short period electrical stimuli to observe muscle fibers contracting continuously (tetanus).Chemical agents can cause tetanus by interfering with the motor neurons. These agents include atoxin produced by the soil bacterium Clostridium tetani. One of the symptoms of these agents iscalled 'spastic paralysis'! Explain in your own words why these agents would be a bad thing for youand your muscles.

Calculate the empirical formula for each over-the-counterpain reliever(a) acetaminophen (Tylenol): C, 63.56%; H, 6.00%;N, 9.27%; O, 21.17%(b) naproxen (Aleve): C, 73.03%; H, 6.13%; O, 20.84%
