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.
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 = 1000This is the initial Value of acetaminophen in the body just after taking the normal dose ; At time, t = 0Fraction left after 1 hour = 0.75Amount 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 = 0.75Amount 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]

What is the best buy for the following advertise sale on pop A(eight cans for $4.88 B(10 cans for $5.80 or C(3 cans for d cans for $7.20
Buying 10 cans for $5.80 is the best deal.
What is unitary method?The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
According to the question
We have
Cost of eight cans is $4.88
⇒ cost of one can = [tex]\frac{4.88}{8}[/tex] = $0.61
Cost of 10 cans is $5.80
⇒ cost of one can = [tex]\frac{5.80}{10}[/tex] =$0.58
Cost of 3 cans is $7.20
⇒ cost of one can = [tex]\frac{7.20}{3}[/tex] = $2.4
Hence, buying 10 cans for $5.80 is the best deal.
