the amount of caffeine in a persons body follows an exponential function, as do many drugs. the half life of caffeine is typically about 5.5 hours. if you drink a can of Red Bull, you put 80 mg of caffeine into your body. how long will it be until the amount of caffeine drops to 50 mg?

Solutions

Expert Solution

Note :

1. The general expression for exponential decay/depletion of a quantity is of the form

N = A. e^(-kt), where 'A' and 'k' are constants; 'A' being the initial quantity.

2. Half-life is the time required for the initial quantity to reduce to its half value.

Kevin's body metabolizes caffeine at a rate of 14.4% per hour (so the amount of caffeine in Kevin's body decreases by 14.4% each hour). If Kevin consumes a cup of coffee with 86 mg of caffeine in it, how long will it take for Kevin's body to metabolize half of the 86 mg of caffeine? If Kevin consumes an energy drink with 200 mg of caffeine in it, how long will it take for Kevin's body to metabolize half of...

The body removes antibacterial drugs at a rate in proportion to the amount present. Your task is to: Express this as a differential equation. Assume the initial dosage is 450 milligrams. 7 hours later, 50 milligrams remain inside the body. Determine the decay constant. Proceed given the facts in the previous statement. How long after the drug was administered would 200 milligrams be found in the body?

Many cancer drugs have been developed that inhibit or activate enzyme function. a. Geftinib is a tyrosine kinase inhibitor that has been shown to specifically target EGFR. EGFR is a receptor tyrosine kinase (RTK) and can become constitutively active in a cancer cell. Before we continue, explain how a RTKs function to transmit a signal (EGF) from the outside of the cell across the membrane to the inside of the cell. Be specific, what changes occur on the outside of...

6) In our body, there are many types’ of tissues which perform their physiological function according to our body’s requirement. Some of the tissues are soft, fluid and hard in nature. When we are growing old, the hard type of tissue becomes weak and doctors generally prescribe supplements which are required to strengthen them. Based on the above discussion, answer the following questions. a) List the possible supplements that can be taken to strengthen the above mentioned tissue. Justify your...

A survey​ asked, "How many tattoos do you currently have on your​ body?" Of the 1247 males​ surveyed, 197 responded that they had at least one tattoo. Of the 1025 females​ surveyed, 138 responded that they had at least one tattoo. Construct a 99​% confidence interval to judge whether the proportion of males that have at least one tattoo differs significantly from the proportion of females that have at least one tattoo. Interpret the interval. Let p1 represent the proportion...
