Alcohol absorption In one individual, the percent of alcohol absorbed into the bloodstream after drinking two glasses of wine is given by the following formula. Find the percent of alcohol absorbed into the blood after 12 hour. Pt=0.31-e-0.05t where, t is in minutesarrow_forwardThe intensitylevels I of two earthquakes measured ona seismograph can be compared by the formula logI1I2=M1M2 where M is the magnitude given by the Richter Scale. In August 2009, an earthquake of magnitude 6.1 hitHonshu, Japan. In March 2011, that same regionexperienced yet another, more devastating earthquake, this time with a magnitude of 9.0.[23] Haw many timesgreater was the intensity of the 2011 earthquake?Round to the nearest whole number.arrow_forward
- The formula for measuring sound intensity indecibels D is defined by the equation D=10log (II0), where I is the intensity of the sound in wattsper square meter and I0=1012 is the lowest level ofsound that the average person can hear. How manydecibels are emitted from a largeorchestra with asound intensity of 6.3103 watts per square meter?arrow_forwardThe formula for measuring sound intensityin decibels D is defined by the equation D=10log(II0) where I is the intensity of the sound in watts persquare meter and I0=1012 is the lowest level of sound that the average person can hear. How manydecibels are emitted from a rock concert with a sound intensity of 4.7101 watts per square meter?arrow_forwardWhen a certain drug is taken orally, the concentration of the drug in the patient's bloodstream After t minutes is given by C(t)=0.06t0.0002t2 where 0t240 and concentration is measured in mg/L .When is the maximum serum concentration reached, and what is that maximum concentration?arrow_forward
