Acetaminophen is a common pain reliever and fever reducer. Here is a graph showing the amount of acetaminophen, in milligrams, in an adult's body at different times after they take a normal dose. 1. What is the vertical intercept? What does it mean in this situation? 2. What fraction of the medicine remained after one hour? 3. Write an equation that represents the amount of medicine, a, after t hours.

Answers

Answer:

I don't know 1

2. 3/4

3. y= 1000(0.75)^x

Step-by-step explanation:

According to the information depicted on the graph:

Vertical intercept = 1000

This is the initial Value of acetaminophen in the body just after taking the normal dose ; At time, t = 0

Fraction left after 1 hour = 0.75

Amount after t hours = [tex]y(t) = 1000(0.75)^{t}[/tex]

The vertical intercept is the value of the y - intercept, where the line crosses the y - axis. ; vertical intercept = 1000

The y - intercept is the amount of the drug in the body 0 minutes after taking it.

Fraction of drug left after one hour :

t(1) ÷ t(0) = 750 / 1000 = 3/4 = 0.75

Amount of medicine left after t hours :

Initial amount(rate of decrease)^time

[tex]y(t) = 1000(0.75)^{t}[/tex]

Hence, the function which models the graph is [tex]y(t) = 1000(0.75)^{t}[/tex]

It is produced from an ore that contains ilmenite (FeTiO3) and ferric oxide (Fe2O3). The ore is digested with an aqueous sulfuric acid solution to produce an aqueous solution of titanyl sulfate [(TiO)SO4 ] and ferrous sulfate (FeSO4 ). Water is added to hydrolyze the titanyl sulfate to H2TiO3, which precipitates, and H2SO4. The precipitate is then roasted, driving off water and leaving a residue of pure titanium dioxide. (Several steps to remove iron from the intermediate solutions as iron sulfate have been omitted from this description.) Suppose an ore containing 24.3% Ti by mass is digested with an 80% H2SO4 solution, supplied in 50% excess of the amount needed to convert all the ilmenite to titanyl sulfate and all the ferric oxide to ferric sulfate [Fe2 (SO4 )3 ]. Further suppose that 89% of the ilmenite actually decomposes. Calculate the masses (kg) of ore and 80% sulfuric acid solution that must be fed to produce 1000 kg of pure TiO2.
