6.1²66.7t + 3000t² +573=The function p(t) = 6.1t²-66.7t+3000/t²+573 models the pH level p(t) of a mouth t minutes after eating food containing sugar.a) Find, to the nearest tenth, the pH of a mouth 30 minutes after eating a food containing sugar.b) Find the equation of the horizontal asymptote.c) What happens to the pH level of a mouth as the time since eating the sugary food increases?The mouth returns to its normal pH of 6.1.The mouth returns to its normal pH of 5.24.The sugar keeps the pH of the mouth at abnormal levels until the end of time.The pH of the mouth approaches 0.
